I have a problem about screen rotation. I know that I must use method "onSaveInstanceState(Bundle outState)" but I have no ideal how it works. My application have to add the "marker" to Google Map.
class AddMarker extends Fragment{
private static final String KEY = "marker";
private ArrayList<LatLng> mData;
private GoogleMap mMap;
private MapView mMapView;
#Override
public void onSaveInstanceState(Bundle outState) {
outState.putParcelableArrayList(KEY, mData);
super.onSaveInstanceState(outState);
mapView.onSaveInstanceState(outState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
View v = inflater.inflate(R.layout.map, container, false);
mMapView = (MapView) v.findViewById(R.id.mapview);
mMapView.onCreate(savedInstanceState);
mMap = mMapView.getMap();
mMap.setMyLocationEnabled(true);
if((savedInstanceState != null)
&& (savedInstanceState.getParcelableArrayList(KEY) != null)){
mData = savedInstanceState.getParcelableArrayList(KEY);
// What should I do here ????
// call drawMarker(mData) ???
}
else
drawMarker(mData);
return v;
}
}

I am trying to build a Grid View inside Expandable list view. The problem i am facing is that the the columns in gridview are repeating no matter the number of columns i specify in xml. please find below the code and screen shot. That is there are two child view A and B. Instead of each coming in a single row. A is coming completely on 1st row no matter the number of columns and B is coming on the complete second rows.

may I ask how to pass the value to other Activity using the code below? This is because I want to pass each value of TextView in my ListView to another Activity. Thank you.
public class MySimpleArrayAdapter extends ArrayAdapter<String> {
private final Context context;
private final ArrayList<String> values;
public MySimpleArrayAdapter(Context context, ArrayList<String> values) {
super(context, R.layout.rowlayout, values);
this.context = context;
this.values = values;
}
/**
* Here we go and get our rowlayout.xml file and set the textview text.
* This happens for every row in your listview.
*/
#Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View rowView = inflater.inflate(R.layout.rowlayout, parent, false);
TextView textView = (TextView) rowView.findViewById(R.id.criteriaName);
final TextView textView2 = (TextView)rowView.findViewById(R.id.txtView2);
SeekBar seekBar = (SeekBar)rowView.findViewById(R.id.sbBar);
// Setting the text to display
textView.setText(values.get(position));
seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar, int i, boolean b) {
textView2.setText(""+i);
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
});
return rowView;
}
}
So, how am I going to pass the value in TextView2 to another Activity?
At first convert you Textview to a String then , do this
Intent i = new Intent(CurrentActivity.this,ClassOfNextActivity.class);
i.putExtra("My_String",convertedString);
startActivity(i);
On the next Activty you have to do this, to get your String from your first Activity.
Intent i = getIntent();
String newString = (String) i.getSerializableExtra(My_String):
I've been searching everywhere for the solution, but it has come to a dead end.
Please help!
I record and save the video as the follow:
File DirectoryFile = new File(VideoPath);
recorder.setOutputFile(DirectoryFile.getAbsolutePath());
I load all the videos and set the ListView adapter from the userPath as follow:
private File[] getNewImageFilesWithFilters() {
File directory = new File(UserSavedDirectoryPATH);
return directory.listFiles(new FilenameFilter() {
public boolean accept(File dir, String name) {
return name.toLowerCase(Locale.getDefault()).endsWith(".mp4")
|| name.toLowerCase(Locale.getDefault()).endsWith(".mkv");
}
});
}
public void LoadListView() {
for (File file : listFile){
mVideoListViewObject = new VideoListViewObject();
mVideoListViewObject.setName(file.getName());
mVideoListViewObject.setVideoUrl(file.getAbsolutePath());
VideoListViewObject_List.add(mVideoListViewObject);
}
mVideoListViewAdapter = new VideoListAdapter(this, VideoListViewObject_List);
mListView.setAdapter(mVideoListViewAdapter);
}
The ListView Adapter:
public class VideoListAdapter extends BaseAdapter {
private List<VideoListViewObject> VideoObjectList;
private Context mContext;
public VideoListAdapter(Context context, List<VideoListViewObject> newList){
this.mContext = context;
this.VideoObjectList = newList;
}
#Override
public int getCount() {
return VideoObjectList.size();
}
#Override
public VideoListViewObject getItem(int position) {
return VideoObjectList.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
ViewHolder viewHolder = new ViewHolder();
LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (convertView == null) {
convertView = inflater.inflate(R.layout.listview_layout, parent, false);
viewHolder.imageView = (ImageView)convertView.findViewById(R.id.ListViewImage);
viewHolder.layout = (RelativeLayout)convertView.findViewById(R.id.ListViewLayout);
convertView.setTag(viewHolder);
}
else
{
viewHolder = (ViewHolder)convertView.getTag();
}
Bitmap bmThumbnail = ThumbnailUtils.createVideoThumbnail(VideoObjectList.get(position).getVideoUrl(),Thumbnails.MICRO_KIND);
viewHolder.imageView.setImageBitmap(bmThumbnail);
The problem is the list is slow to load, especially when there are a lot of videos.
This causes my VideoaAtivity to start very slow.
I love Piscasso and Universal Image Loader, but they only support images.
Does anyone know a better solution or a library that would help with the performance?
Thank you very much.
I just modified my own application to do similar logic to pre-create the thumbnails which made the list scroll very fast at the start, Add the thumbnail bitmap to the videoListViewObject and create the thumbnail
when loading the video list. this way you do not have to create it every time getView is called in your adapter.
public class VideoListViewObject{
private Bitmap bitmap = null;
............................
public void setBitmap(Bitmap bitmap)
{
this.bitmap = bitmap;
}
public Bitmap getBitmap()
{
return this.bitmap;
}
}
public void LoadListView() {
for (File file : listFile){
mVideoListViewObject = new VideoListViewObject();
mVideoListViewObject.setName(file.getName());
mVideoListViewObject.setVideoUrl(file.getAbsolutePath());
Bitmap bmThumbnail = ThumbnailUtils.createVideoThumbnail(VideoObjectList.get(position).getVideoUrl(),Thumbnails.MICRO_KIND);
mVideoListViewObject.setBitmap(bmThumbnail);
VideoListViewObject_List.add(mVideoListViewObject);
}
mVideoListViewAdapter = new VideoListAdapter(this, VideoListViewObject_List);
mListView.setAdapter(mVideoListViewAdapter);
}
then change your BaseAdapter code to only create the thumbnail if it is null,
public class VideoListAdapter extends BaseAdapter {
private List<VideoListViewObject> VideoObjectList;
private Context mContext;
public VideoListAdapter(Context context, List<VideoListViewObject> newList){
this.mContext = context;
this.VideoObjectList = newList;
}
#Override
public int getCount() {
return VideoObjectList.size();
}
#Override
public VideoListViewObject getItem(int position) {
return VideoObjectList.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
ViewHolder viewHolder = new ViewHolder();
LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (convertView == null) {
convertView = inflater.inflate(R.layout.listview_layout, parent, false);
viewHolder.imageView = (ImageView)convertView.findViewById(R.id.ListViewImage);
viewHolder.layout = (RelativeLayout)convertView.findViewById(R.id.ListViewLayout);
convertView.setTag(viewHolder);
}
else
{
viewHolder = (ViewHolder)convertView.getTag();
}
VideoListViewObject mVideoListViewObject = getItem(position);
Bitmap bmThumbnail = mVideoListViewObject.getBitmap();
if(bmThumbnail==null)
{
bmThumbnail = ThumbnailUtils.createVideoThumbnail(VideoObjectList.get(position).getVideoUrl(),Thumbnails.MICRO_KIND);
}
viewHolder.imageView.setImageBitmap(bmThumbnail);
