Navigation drawer not working in android lollipop - xamarin

I have in my project Android Design Library and I'm working with navigation view but I have an issue with it. From API 15 till 20 everything is working fine as suppose to work but when I tried on API 21 (5.0) and higher it's not working even it's not showing the hamburger button. And I can't find where is the problem. Does anyone faced with similar problem? I'm working in xamarin with C#. This is the code:

If someone face in future with similar problem this was solution for my problem. As I guessed problem wasn't in code. I added design library via components but that is not the latest version and you will face with errors in android lollipop or higher so add it via NuGet Packages or make an update and you will get the latest version.

MvvmCross Android binding EditText in release mode

I have a problem with binding EditText on Android platform.
Today I update in my project MvvmCross framework from 6.2.X to 6.3.1 (+ update others NuGets) and changed TargetSdk and CompileSdk from Android 8.1 to 9.0 and now when I have Release mode and linking set to "Sdk Assemblies" Only my app crash on View where I have binding EditText. In debug where I have checked "Use Shared Runtime" and set linking to "None" there is no problem it works.
I have Include TextView in LinkerPleaseInclude:
public void Include(TextView text)
{
text.AfterTextChanged += (sender, args) => text.Text = $"{text.Text}";
text.Hint = $"{text.Hint}";
}
it throws this exception: https://pastebin.com/EmkuL7hM

I believe the issue you are experiencing is a current bug in Xamarin's latest build (around Xamarin Android 9.4). This issue can be tracked here on GitHub.
The suggested workaround
In case any other users come across this issue when using
Xamarin.Android 9.4, a possible workaround is to use a custom linker
configuration to preserve the missing types. To do that, add a new
linker.xml file to the project, set the Build Action to
LinkDescription, and add the XML lines to preserve the missing types.
For example, for the ITextWatcherInvoker error, add the following
lines to the file:
<linker>
<assembly fullname="Mono.Android">
<type fullname="Android.Text.ITextWatcherInvoker" preserve="all" />
</assembly>
</linker>

in your HomeFragment.cs in the OnCreateView method add the following (between the declaration of view and the return statment):
var btnProducts = view.FindViewById<Button>(Resource.Id.btnProducts);
btnProducts.Click += btnProducts_Click;
Then add the method for your click event (somewhere in your HomeFragment class):
public void btnProducts_Click(object sender, EventArgs e)
{
// Action you want to take upon button click
}

Unable to convert instance of type 'Android.Widget.EditText' to type 'Android.Widget.Button'

I try to execute the following tutorial :
namespace App1
{
[Activity(Label = "App1", MainLauncher = true, Icon = "#drawable/icon")]
public class MainActivity : Activity
{
int count = 1;
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
// Set our view from the "main" layout resource
SetContentView(Resource.Layout.Main);
// Get the latitude/longitude EditBox and button resources:
EditText latitude = FindViewById<EditText>(Resource.Id.latText);
EditText longitude = FindViewById<EditText>(Resource.Id.longText);
Button button = FindViewById<Button>(Resource.Id.getWeatherButton);
// When the user clicks the button ...
button.Click += async (sender, e) => {
// Get the latitude and longitude entered by the user and create a query.
string url = "http://api.geonames.org/findNearByWeatherJSON?lat=" +
latitude.Text +
"&lng=" +
longitude.Text +
"&username=demo";
// Fetch the weather information asynchronously,
// parse the results, then update the screen:
JsonValue json = await FetchWeatherAsync(url);
// ParseAndDisplay (json);
};
}
// Gets weather data from the passed URL.
private async Task<JsonValue> FetchWeatherAsync(string url)
{
// Create an HTTP web request using the URL:
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(new Uri(url));
request.ContentType = "application/json";
request.Method = "GET";
// Send the request to the server and wait for the response:
using (WebResponse response = await request.GetResponseAsync())
{
// Get a stream representation of the HTTP web response:
using (Stream stream = response.GetResponseStream())
{
// Use this stream to build a JSON document object:
JsonValue jsonDoc = await Task.Run(() => JsonObject.Load(stream));
Console.Out.WriteLine("Response: {0}", jsonDoc.ToString());
// Return the JSON document:
return jsonDoc;
}
}
}
}
}
but when I debug it a pop-up open with the following message : "System.InvalidCastException: Unable to convert instance of type 'Android.Widget.EditText' to type 'Android.Widget.Button'."

Horizontal RecyclerViews inside vertical RecyclerView scrolling jerks

I am using a layout in which I used multiple RecyclerViews (Horizontal) as a item view of RecyclerView. The problem is that the vertical scrolling is not as smooth as I am expecting.There are some jerks in while scrolling vertically(Parent RecyclerView).
How to remove these vertical scrolling jerks ? I used to set adapters to horizontal RecyclerViews in OnBindViewHolder() method of Parent RecyclerView.
I have solved the problem.
Scrolling performance is much better in this case.
Do not set adapters to horizontal RecyclerViews in OnBindViewHolder() method of Parent RecyclerView.
Instead of it set it at very first time when the view is created via onCreateViewHolder() of RecyclerView with empty or null dataList.
Just replace the new secondary data list with previous null list at onBindViewHolder() and call notifydataSetChanged() to HorizontalAdapetr.
This is much better than setAdapter() in onBindViewHolder().
You can try this way
main activity
public void initialize(List<List<ResponseObject>> responseObjectList) {
RecyclerView upperRecyclerView = (RecyclerView) this.findViewById(R.id.main_layout);
upperRecyclerView.setLayoutManager(new LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false));
VerticalAdapter adapter = new VerticalAdapter(this, responseObjectLists);
upperRecyclerView.setAdapter(adapter);
adapter.notifyDataSetChanged();
}
Vertical recycled view adapter
public class VerticalAdapter extends RecyclerView.Adapter<VerticalAdapter.Holder> {
final private SearchActivity activity;
List<List<ResponseObject>> list;
public VerticalAdapter(SearchActivity activity, List<List<ResponseObject>> lists) {
this.list = lists;
this.activity = activity;
}
public Holder onCreateViewHolder(ViewGroup parent,int viewType) {
View itemLayoutView = LayoutInflater.from(parent.getContext())
.inflate(R.layout.vertical_layout, null);
return new Holder(itemLayoutView);
}
public void onBindViewHolder(Holder viewHolder, int position) {
List<ResponseObject> objectList = list.get(position);
viewHolder.packageTitle.setText(objectList.get(0).getTag());
ImageAdapter imageAdapter = new ImageAdapter(activity, objectList);
viewHolder.horizontalRecyclerView.setLayoutManager(new LinearLayoutManager(activity, LinearLayoutManager.HORIZONTAL, false));
viewHolder.horizontalRecyclerView.setAdapter(imageAdapter);
viewHolder.horizontalRecyclerView.setNestedScrollingEnabled(false);
imageAdapter.notifyDataSetChanged();
}
public final static class Holder extends RecyclerView.ViewHolder {
protected TextView packageTitle;
protected RecyclerView horizontalRecyclerView;
public Holder(View view) {
super(view);
this.packageTitle = (TextView) view.findViewById(R.id.recycleViewTitle);
this.horizontalRecyclerView = (RecyclerView) view.findViewById(R.id.recyclerView);
this.horizontalRecyclerView.setLayoutManager(new LinearLayoutManager(this.horizontalRecyclerView.getContext(), LinearLayoutManager.HORIZONTAL, false));
this.horizontalRecyclerView.setNestedScrollingEnabled(false);
horizontalRecyclerView.setAdapter(null);
}
}

return ListUtil.isEmpty(list) ? 0 : list.size();
}
}

this.mainPageResponseList = mainPageResponseList;
this.activity = activity;
}
public ImageAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemLayoutView = LayoutInflater.from(parent.getContext())
.inflate(R.layout.horizontal_layout_view, null);

return viewHolder;
}
