I have a videoview on my app and Im using gogole as a reference to make the video player full screen:

https://developer.android.com/training/system-ui/immersive#java

I was following the instruccion from the above website and i was able to make the videoplayer full screen but I gt a weird problem with my media controller and the device controller(they overlp) and don't know how to fixed any ideas what is the problem.

enter image description here

public class VideoPlayer extends AppCompatActivity {

    VideoView videoView;
    MediaController mediaController;
    private String TAG = VideoPlayer.class.getSimpleName();
    @RequiresApi(api = Build.VERSION_CODES.KITKAT)
    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.video_player_activity);

        videoView = (VideoView) findViewById(R.id.videoView);
        mediaController = new MediaController(this);
        videoView.setVideoPath("android.resource://" + getPackageName() + "/" + R.raw.video1);
        mediaController.setAnchorView(videoView);
        videoView.setMediaController(mediaController);
        videoView.start(); 

    }

    @Override
    public void onWindowFocusChanged(boolean hasFocus) {
        super.onWindowFocusChanged(hasFocus);
        if (hasFocus) {
            hideSystemUI();
        }
    }

    private void hideSystemUI() { 
        View decorView = getWindow().getDecorView();
        if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
            decorView.setSystemUiVisibility(
                    View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                            | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                            | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                            | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION // hide nav bar
                            | View.SYSTEM_UI_FLAG_FULLSCREEN // hide status bar
                            | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
        }
    } 
    private void showSystemUI() {
        Log.e(TAG, "111");
        View decorView = getWindow().getDecorView();
        decorView.setSystemUiVisibility(
                View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                        | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                        | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
    }
}
Solution

  • Here is the fix for you. You have to update your controls margin dynamically by code. Idea is that add one overlay with controls in your layout file. and when navigation bar is visible update your controls bottom margin to push them up in screen. Rest code explains it worked for me.

    Layout File : video_player_activity.xml

    <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
                android:orientation="vertical"
                android:layout_width="match_parent"
                android:layout_height="match_parent">
    <VideoView android:layout_width="match_parent" android:layout_height="match_parent" android:id="@+id/videoView"/>

    <TextView android:id="@+id/text" android:layout_width="match_parent" android:layout_height="wrap_content"
              android:text="Video Controls" android:textStyle="bold" android:textSize="40sp"
              android:textColor="#FFF"
              android:background="#444444"
              android:gravity="center"
              android:layout_alignParentBottom="true"/>

    <View android:visibility="gone" android:layout_width="match_parent" android:layout_height="match_parent"
          android:id="@+id/overlay"/>

</RelativeLayout>
