RecyclerView gets Recreated when the videoview is in fullscreen

Question

I have a recyclerview which onClick shows a videoview with fullscreen button..

However when i click the full screen button on the videoview.. My RecyclerView gets displayed (or created) again..

I want to display only the video in the videoview in the fullscreen mode..

The following is my Acticity OnCreate() Method :

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mangal_stuti_activity);
toolbar = findViewById(R.id.toolbar);
toolbar.setBackgroundColor(getResources().getColor(R.color.colorPrimary));
setSupportActionBar(toolbar);
recyclerView = (findViewById(R.id.recycler_view));
mAdapter = new Adapter(this, movieList, this);

RecyclerView.LayoutManager mLayoutManager = new LinearLayoutManager(getApplicationContext());
recyclerView.setLayoutManager(mLayoutManager);
recyclerView.setItemAnimator(new DefaultItemAnimator());
recyclerView.addItemDecoration(new MyDividerItemDecoration(this, LinearLayoutManager.VERTICAL,16));
recyclerView.setAdapter(mAdapter);
recyclerView.setBackgroundColor(getResources().getColor(R.color.recyclerViewBackground));
recyclerView.addOnItemTouchListener(new RecyclerTouchListener(getApplicationContext(), this.recyclerView, new RecyclerTouchListener.ClickListener()
{
  public void onClick(View view, int position) {
    toolbar.setVisibility(View.GONE);
      playVideo();

  }

  public void onLongClick(View paramAnonymousView, int paramAnonymousInt) {}
}));

prepareMovieData();  // possibly this function is creating the recyclerview again when the fullScreen is called..

mVideoView = findViewById(R.id.videoView);
mYouTuDraggingView = findViewById(R.id.youtube_view);
mYouTuDraggingView.setCallback(this);

controlPanel = new YoutubeControlPanel(this);
controlPanel.setYouTuDraggingView(mYouTuDraggingView);
mVideoView.setControlPanel(controlPanel);
controlPanel.getFullScreenIv().setOnClickListener(new View.OnClickListener() {
  @Override
  public void onClick(View v) {
    mYouTuDraggingView.fullScreenChange();
  }
});
controlPanel.getDownIv().setOnClickListener(new View.OnClickListener() {
  @Override
  public void onClick(View v) {
    toolbar.setVisibility(View.VISIBLE);
    mYouTuDraggingView.fullScreenGoMin();
  }
});
}

The fullScreenChange() in YouTuDraggingView class is as below:

void fullScreenChange() {
    if (isLandscape()) {
        isLandscapeToPortrait = true;
        mActivity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR_PORTRAIT);
    } else {
        isPortraitToLandscape = true;
        mActivity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR_LANDSCAPE);
    }
}

The mangal_stuti_activity.xml

<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout
tools:context="com.amitabh.dhamma_jaagran.MangalStuti"
android:orientation="vertical"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:background="@color/recyclerViewBackground"
android:id="@+id/activity_main"
xmlns:tools="http://schemas.android.com/tools"
xmlns:android="http://schemas.android.com/apk/res/android">
<include layout="@layout/toolbar_stuti_activities"/>

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <android.support.v7.widget.RecyclerView
        android:id="@+id/recycler_view"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

    </android.support.v7.widget.RecyclerView>

    <com.amitabh.YouTuDraggingView
        android:id="@+id/youtube_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="bottom"
        android:orientation="vertical"
        android:visibility="invisible"/>

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentStart="true"
        android:id="@+id/footer_text"
        android:layout_alignParentLeft="true"
        android:layout_alignParentBottom="true"
        android:layout_gravity="bottom"
        android:background="@color/colorPrimaryDark"
        android:text="@string/copyright_footer"
        android:textAlignment="center"
        android:textColor="@color/white" />


</RelativeLayout>
</LinearLayout>

When i click the fullscreen button on the videoview.. the videoview only should show on the fullscreen.. not the recyclerview...

i think the problem might be in mAdapter = new Adapter(this, movieList, this); where another movieList gets created when the videoview enters fullscreen..

Any help regarding this would be of great help to me.. thanks in advance..

Answer 1

I Just added this line to my activity in which the video is being played in the AndroidManifest.xml file

android:configChanges="orientation|screenSize" 

This prevented the activity from being recreated.
