I am using asy task with adapter and get this error
java.lang.NullPointerException
the problem line is
listAdapter = new listAdpterRss(this.context, R.layout.listitems,RssArrays,RssArrays.rtl);
my asy task looks like that
protected void onPostExecute(String result) {
Dialog.dismiss();
ListView lv = getListView();
// lv.setTextFilterEnabled(true);
listAdapter = new listAdpterRss(this.context, R.layout.listitems,RssArrays,RssArrays.rtl);
lv.setAdapter(listAdapter); // on test
listAdapter.notifyDataSetChanged();
lv.setOnItemClickListener(new OnItemClickListener()
{
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Intent intent = new Intent(RssItem.this,openRssItem.WebActivity.class);
intent.putExtra("url", RssArrays.PodcastURL[position].toString());
startActivity(intent);
//new splash(ListRss.this,mHandler,listValue.get(position).toString()).execute();
}
});
You are setting adapter later and might be using in you doInBackground method . Thats why it is showing nullPointer.
Please put all of these onPreExecute():
ListView lv = getListView();
// lv.setTextFilterEnabled(true);
listAdapter = new listAdpterRss(this.context, R.layout.listitems,RssArrays,RssArrays.rtl);
lv.setAdapter(listAdapter);
And then try your code.

Please provide the solution.
Where exactly is your exception coming from? Did you manage to get the origin?
And in case you are talking about the exception from the ConfigurationManager.Initialize() method, try this.
if(Configurationmanager.AppSettings == null)
{
ConfigurationManager.Initialise(PCLAppConfig.FileSystemStream.PortableStream.Current);
}
Its just that the ConfigurationManager throws an exception if it already finds a NameValueCollection initialized.
This is going to be a long post! (grab a cup of coffee/popcorn)
I am using AltBeacon Xamarin sample in my code to show the beacons.
I have come across this example in creating Notifications in Xamarin.
Here there's an Application class where the core logic goes.
public class AltBeaconSampleApplication : Application, IBootstrapNotifier
{
private const string TAG = "AltBeaconSampleApplication";
BeaconManager _beaconManager;
private RegionBootstrap regionBootstrap;
private Region _backgroundRegion;
private BackgroundPowerSaver backgroundPowerSaver;
private bool haveDetectedBeaconsSinceBoot = false;
private string nearbyMessageString = "A beacon is nearby.";
private string nearbyTitleString = "AltBeacon Reference Application";
private MainActivity mainActivity = null;
public MainActivity MainActivity
{
get { return mainActivity; }
set { mainActivity = value; }
}
private NotificationActivity notificationActivity = null;
public NotificationActivity NotificationActivity
{
get { return notificationActivity; }
set { notificationActivity = value; }
}
public AltBeaconSampleApplication() : base() { }
public AltBeaconSampleApplication(IntPtr javaReference, Android.Runtime.JniHandleOwnership transfer) : base(javaReference, transfer) { }
public override void OnCreate()
{
base.OnCreate();
_beaconManager = BeaconManager.GetInstanceForApplication(this);
var iBeaconParser = new BeaconParser();
// Estimote > 2013
iBeaconParser.SetBeaconLayout("m:2-3=0215,i:4-19,i:20-21,i:22-23,p:24-24");
_beaconManager.BeaconParsers.Add(iBeaconParser);
Log.Debug(TAG, "setting up background monitoring for beacons and power saving");
// wake up the app when a beacon is seen
_backgroundRegion = new Region("backgroundRegion", null, null, null);
regionBootstrap = new RegionBootstrap(this, _backgroundRegion);
// simply constructing this class and holding a reference to it in your custom Application
// class will automatically cause the BeaconLibrary to save battery whenever the application
// is not visible. This reduces bluetooth power usage by about 60%
backgroundPowerSaver = new BackgroundPowerSaver(this);
PerformHttpRequest();
}
public void DidDetermineStateForRegion(int state, AltBeaconOrg.BoundBeacon.Region region)
{
}
public async void PerformHttpRequest()
{
try
{
using (var client = new HttpClient())
{
var uri = "http://exampleuri";
var result = await client.GetStringAsync(uri);
var response = JsonConvert.DeserializeObject<BeaconURL>(result);
SendNotificationFromBeacon(response);
}
}
catch(Exception ex)
{
throw ex;
}
}
private void SendNotificationFromBeacon(BeaconURL receivedNotification)
{
// Setup an intent for SecondActivity:
Intent notificationIntent = new Intent(this, typeof(NotificationActivity));
// Pass some information to SecondActivity:
notificationIntent.PutExtra("CompaignUrl", receivedNotification.CompaignUrl);
notificationIntent.PutExtra("MediaUrl", receivedNotification.MediaUrl);
notificationIntent.PutExtra("titleText", receivedNotification.Title);
notificationIntent.SetFlags(ActivityFlags.NewTask);
// Create a task stack builder to manage the back stack:
Android.App.TaskStackBuilder stackBuilder = Android.App.TaskStackBuilder.Create(this);
// Add all parents of SecondActivity to the stack:
stackBuilder.AddParentStack(Java.Lang.Class.FromType(typeof(NotificationActivity)));
// Push the intent that starts SecondActivity onto the stack:
stackBuilder.AddNextIntent(notificationIntent);
// Obtain the PendingIntent for launching the task constructed by
// stackbuilder. The pending intent can be used only once (one shot):
const int pendingIntentId = 0;
PendingIntent pendingIntent =
stackBuilder.GetPendingIntent(pendingIntentId, PendingIntentFlags.OneShot);
// Instantiate the builder and set notification elements, including
// the pending intent:
var builder =
new NotificationCompat.Builder(this)
.SetContentTitle(receivedNotification.Title)
.SetContentText(receivedNotification.Text)
.SetSmallIcon(Android.Resource.Drawable.IcDialogInfo);
// Build the notification:
Notification notification = builder.Build();
// Get the notification manager:
NotificationManager notificationManager =
GetSystemService(Context.NotificationService) as NotificationManager;
// Publish the notification:
const int notificationId = 0;
notificationManager.Notify(notificationId, notification);
}
}
BeaconURL is a POCO class
NotificationActivity is a basic Activity class.
I perform the HttpClient request and get data. I create a notification and present it on my screen. It goes like this
Now when I tap on the notification, I dont go to the NotificationActivity. I am trying to invoke an activity from an ApplicationClass. Is this the right way to perform such stuff. Kindly provide details.
Thanks.
Edit: Added NotificationActivity Class
[Activity(Label = "NotificationActivity")]
public class NotificationActivity : MainActivity
{
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
// Create your application here
SetContentView(Resource.Layout.NotificationLayout);
TextView titleTextView = FindViewById<TextView>(Resource.Id.txtTitle);
titleTextView.Text = Intent.Extras.GetString("titleText", "");
ImageView mediaImage = FindViewById<ImageView>(Resource.Id.imgViewMedia);
mediaImage.SetImageBitmap(GetImageBitmapFromUrl(Intent.Extras.GetString("MediaUrl", "")));
}
private Bitmap GetImageBitmapFromUrl(string url)
{
Bitmap imageBitmap = null;
using (var webClient = new WebClient())
{
var imageBytes = webClient.DownloadData(url);
if (imageBytes != null && imageBytes.Length > 0)
{
imageBitmap = BitmapFactory.DecodeByteArray(imageBytes, 0, imageBytes.Length);
}
}
return imageBitmap;
}
}
First thing you need to do is to set the your pending intent within the notification builder, it will get your NotificationActivity launching:
var builder =
new NotificationCompat.Builder(this)
.SetContentTitle("receivedNotification.Title")
.SetContentText("receivedNotification.Text")
.SetSmallIcon(Android.Resource.Drawable.IcDialogInfo)
.SetContentIntent(pendingIntent);
The second will be to get your back stack setup, from what you posted I'm not sure what the flow should be as the user will exit the app if they use the back button.
If you want the user to go back to the MainActivity when that press the back button, then you can add a ParentActivity to your NotificationActivity activity attribute, i.e.:
[Activity(Label = "NotificationActivity", ParentActivity = typeof(MainActivity))]
And thus the line:
stackBuilder.AddParentStack(Java.Lang.Class.FromType(typeof(NotificationActivity)));
Would add the MainActivity to the back stack.
I have class myClass extends TreeItem<file> to be used as datamodel in a TreeTableView mostly following the example here: https://docs.oracle.com/javase/8/javafx/api/javafx/scene/control/TreeItem.html .
public class myTreeItem extends TreeItem<File>
private boolean isLeaf;
private boolean isFirstTimeChildren = true;
private boolean isFirstTimeLeaf = true;
#Override public ObservableList<TreeItem<File>> getChildren() {
// ... full code see link to Oracle documentation
return super.getChildren();
}
private ObservableList<TreeItem<File>> buildChildren(TreeItem<File> TreeItem) {
// ... full code see link to Oracle documentation
};
}
I have added a function to add children to this item. I have problems with the correct update of the TreeTableView. More details see in the code and comments below:
public void addChild(String name) {
itemManger.addChild(this.getValue(), name); // Generate Child
isFirstTimeChildren = true; // Ensure that buildChildren() is called, when getchildren() is called.
// getChildren(); // If I would activate this line,
// all listeners would be notified
// and the TreeTableView is updated.
// This is most likely due to the call super.getChildren();
// However I want to throw the event on my own in order
// to avoid the extra call of this.getChildren(). Here is my
// (not sufficent) try:
EventType<TreeItem.TreeModificationEvent<MLDCostumizableItem>> eventType = TreeItem.treeNotificationEvent();
TreeModificationEvent<MLDCostumizableItem> event = new TreeModificationEvent<>(eventType,this);
Event.fireEvent(this, event);
// Here I don't know how to get a value for target.
// Is there some standard target, which includes all FX components?
}
How the correctly throw this event?
Seems that I had a missunderstanding in how the triggering works in JavaFX. Now the most simple solution is:
#Override // Taken from Link
public void update(Observable observ, Object arg1) {
if (observ!=this.item)
{
LOGGER.error(new MLDConnectionException("Unexpected call of update() with observ = " + observ.toString()));
return;
}
// Build new Chidren list
try {
super.getChildren().removeIf((x) -> true); // empty list
super.getChildren().setAll(buildChildren(this));
} catch (MLDConnectionException e) {
LOGGER.error("Error when genereting children List: ", e);
}
}
public File addChild(String name) throws MLDException {
File newChild = itemManger.addChild(item, name);
update(this.item, null);
return newChild;
}
I have programmed an Android App with fragments. A ListView fragment and a detail fragment.
What I wanna do is, if someone clicks inside the detail activity, a layout which is "View.Gone" should be "View.Visible". The code works without errors but nothing changed on the screen.
You can see it in Detail fragment code where a clik event on the ImageButton btn is.
What do i wrong?
What is the best way to update the detail screen? If someone has a small example or could write me where in my code I have to change what, it makes me happy :-)
Thanks a lot

The FragmentActivity:
public class CacheFragment extends SherlockFragmentActivity {
CacheListFragment f;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.list_cachelist);
f = new CacheListFragment();
// Supply index input as an argument.
Bundle args = new Bundle();
f.setArguments(args);
}
Here's the Detail Fragment, where you can see whatt should happen if someone clicks on the Imagebutton:
public class CacheDetailsFragment extends SherlockFragment implements OnClickListener {
private CacheDetailsLoading cdLoad= new CacheDetailsLoading();
private static GeocacheDetails _cacheDetails = new GeocacheDetails();
private static GCRatingTyp _cacheVote = new GCRatingTyp();
private CacheDetailsUsing cdUsing = new CacheDetailsUsing();
private Activity _context;
private static CacheDetailsFragment f;
private View view;
/**
* Create a new instance of DetailsFragment, initialized to
* show the text at 'index'.
*/
public static CacheDetailsFragment newInstance(int index ) {
f = new CacheDetailsFragment();
// Supply index input as an argument.
Bundle args = new Bundle();
args.putInt("index", index);
f.setArguments(args);
return f;
}
public int getShownIndex() {
return getArguments().getInt("index", 0);
}
public void setCacheDetail(GeocacheDetails cacheDetails)
{
_cacheDetails = cacheDetails;
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
if (container == null) {
return null;
}
Bundle bundle=getArguments();
_cacheVote= bundle.getParcelable("cacheVote");
int index = bundle.getInt("index");
_cacheDetails=StaticCacheListByGroup.getCacheList().get(index);
_context = getActivity();
_context.setTheme(R.style.Theme_Sherlock_Light_DarkActionBar);
view = inflater.inflate(R.layout.list_cachedetails, container,false);
((RelativeLayout) view.findViewById(R.id.relativeLoggingInfo)).setVisibility(View.GONE);
((RelativeLayout) view.findViewById(R.id.relativeKategorienInfo)).setVisibility(View.GONE);
ImageButton btn = (ImageButton) view.findViewById(R.id.description_expand);
btn.setOnClickListener(new OnClickListener() {
public void onClick(View v)
{
if(((RelativeLayout) getActivity().findViewById(R.id.relativeDescriptionInfo)).getVisibility() == View.GONE)
{
((ImageButton) getActivity().findViewById(R.id.description_expand)).setBackgroundResource(R.drawable.navigation_collapse_dark);
((RelativeLayout) getActivity().findViewById(R.id.relativeDescriptionInfo)).setVisibility(View.VISIBLE);
}
else
{
((ImageButton) getActivity().findViewById(R.id.description_expand)).setBackgroundResource(R.drawable.navigation_expand_dark);
((RelativeLayout) getActivity().findViewById(R.id.relativeDescriptionInfo)).setVisibility(View.GONE);
}
});
return view;
}
}
Now the Listfragment:
public class CacheListFragment extends SherlockListFragment {
boolean isDualPane;
int mCurCheckPosition = 0;
private CacheListArrayAdapter _adapter;
private SharedPrefs _sp= new SharedPrefs();
private double latitude=0;
private double longitude=0;
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
latitude =Double.parseDouble(_sp.getSharedPrefs(getActivity(), LibraryDefaults.PROGRAMMNAME, "Latitude", "0"));
longitude =Double.parseDouble(_sp.getSharedPrefs(getActivity(), LibraryDefaults.PROGRAMMNAME, "Longitude", "0"));
// Check to see if we have a frame in which to embed the details
// fragment directly in the containing UI.
View detailsFrame = getActivity().findViewById(R.id.details);
isDualPane = detailsFrame != null && detailsFrame.getVisibility() == View.VISIBLE;
if(!isDualPane)
{
Bundle bundle = getActivity().getIntent().getExtras();
if(bundle != null && bundle.containsKey("Titel"))
((TextView) getActivity().findViewById(R.id.listtitle)).setText(bundle.getString("Titel"));
else
((TextView) getActivity().findViewById(R.id.listtitle)).setText(this.getResources().getString(R.string.caches_listtitle));
}
if (StaticCacheListByGroup.getCacheList() != null)
{
GeocachingCompass gc = new GeocachingCompass(getActivity());
_adapter = new CacheListArrayAdapter(getActivity(), StaticCacheListByGroup.getCacheList(), longitude,latitude);
_adapter.setActualCoordinates(new LatLng(latitude,longitude));
_adapter.setActualHeading(gc.getBearing(latitude,longitude));
if (_adapter != null)
setListAdapter(_adapter);
if (savedInstanceState != null) {
// Restore last state for checked position.
mCurCheckPosition = savedInstanceState.getInt("curChoice", 0);
}
getListView().setChoiceMode(ListView.CHOICE_MODE_SINGLE);
getListView().setSoundEffectsEnabled(true);
getListView().setSmoothScrollbarEnabled(true);
getListView().setDrawSelectorOnTop(false);
getListView().setCacheColorHint(R.color.transparentBlack);
getListView().setDivider(getResources().getDrawable( R.color.divider));
getListView().setDividerHeight(5);
if (isDualPane) {
// In dual-pane mode, the list view highlights the selected item.
getListView().setChoiceMode(ListView.CHOICE_MODE_SINGLE);
showDetails(mCurCheckPosition);
}
}
}
#Override
public void onResume() {
super.onResume();
GeocachingCompass gc = new GeocachingCompass(getActivity());
_adapter = new CacheListArrayAdapter(getActivity(), StaticCacheListByGroup.getCacheList(), longitude,latitude);
_adapter.setActualCoordinates(new LatLng(latitude,longitude));
_adapter.setActualHeading(gc.getBearing(latitude,longitude));
if (_adapter != null)
setListAdapter(_adapter);
}
#Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
outState.putInt("curChoice", mCurCheckPosition);
}
#Override
public void onListItemClick(ListView l, View v, int position, long id) {
showDetails(position);
}
/**
* Helper function to show the details of a selected item, either by
* displaying a fragment in-place in the current UI, or starting a
* whole new activity in which it is displayed.
*/
void showDetails(int index) {
mCurCheckPosition = index;
ReadGCVote getVote = new ReadGCVote();
GeocacheDetails cacheDetails = new GeocacheDetails();
cacheDetails=StaticCacheListByGroup.getCacheList().get(index);
if (isDualPane) {
// We can display everything in-place with fragments, so update
// the list to highlight the selected item and show the data.
getListView().setItemChecked(index, true);
// Check what fragment is currently shown, replace if needed.
CacheDetailsFragment details = (CacheDetailsFragment)
getActivity().getSupportFragmentManager().findFragmentById(R.id.details);
if (details == null || details.getShownIndex() != index) {
// Make new fragment to show this selection.
details = CacheDetailsFragment.newInstance(index);
// Execute a transaction, replacing any existing fragment
// with this one inside the frame.
FragmentTransaction ft = getActivity().getSupportFragmentManager().beginTransaction();
ft.replace(R.id.details, details);
ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE);
ft.commit();
}
} else {
// Otherwise we need to launch a new activity to display
Intent intent = new Intent();
intent.setClass(getActivity(), CacheDetailsActivity.class);
intent.putExtra("index", index);
intent.putExtra("cacheDetails",cacheDetails);
intent.putExtra("cacheVote",getVote.getGCVoteByCacheGuid( StaticGCVoteList.getCacheList(), cacheDetails.GetGUID()));
startActivity(intent);
}
}
}
I found the bug :-)
In the code snippet of the Detail Fragment ...
public void onClick(View v)
{
if(((RelativeLayout) getActivity().findViewById(R.id.relativeDescriptionInfo)).getVisibility() == View.GONE)
}
...you shouldn't use "getActivity()" use "view" from "view = inflater.inflate(R.layout.list_cachedetails, container,false);"
Then it will work
I have two asynctask working with each other. I'm using them for creating Restaurant menu. First web service gets menu's titles from database. Second web service gets items of title from database. I get title data in my first asynctask and item data in my second asynctask.
For example, I have ten menu titles. There are eight items for each title. I execute first asynctask and get all of menu titles. I want to call second asynctask in first asynctask's onPostExecute for get this title's item and add TextView. I have to wait finished every second task for add item respectively.
In short, I need call first AsyncTask and wait finish it. Then send request to second AsyncTask in First AsyncTask. I have to wait every request to finish. How can I wait ?
Here is the my code.

If you want to wait until all AsyncTasks are done before proceeding, why don't you just put all of you work in doInBackground of the first AsyncTask?
Or you don't want to do this because you want to run the 10 "second tasks" in parallel? (Which, incidentally you're not doing anyway, because you're not using the THREAD_POOL Executor for your tasks.) If this is the case then why not just do something like
// variable accessible to both tasks
ArrayList<AsyncTask> mRunningTasks = new ArrayList<AsyncTask>();
// AsyncTask1
protected void onPostExecute(String[][] sonuc){
for(int i=0;i<baslikCount;i++){
MenuDoldurAS kontrol = new MenuDoldurAS(firma_id,sonuc[2][i]);
mRunningTasks.add(kontrol);
}
for (AsyncTask task : mRunningTasks) {
task.execute();
}
}
// AsyncTask2
protected void onPostExecute(...) {
boolean allComplete = true;
for (AsyncTask task : mRunningTasks) {
if (!task.getStatus().equals(AsyncTask.Status.FINISHED)) {
allComplete = false;
break;
}
}
if (allComplete) {
//do whatever
mRunningTasks.clear();
}
}
