Hi I'm trying to achieve an Activity with background made from video file. The solution posted below is working on most devices, except nexus 6 Android 5.1. The video is working, is scaled but is not cropped, so aspect ratio is not preserved.
Tested with Galaxy Note, HTC One m7, Xperia Z3, Nexus 5.
Here is the code:
public class MainActivity extends ActionBarActivity implements SurfaceHolder.Callback, OnClickListener
{
private static final int VIDEO_START_HACK_DELAY = 0;
private static final String BG_VIDEO_PATH = "/raw/construction";
private SurfaceView mSurface;
private Button mTour, mLogin;
private MediaPlayer mMediaPlayer;
private Handler mHandler = new Handler();
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_start_main);
setupUI();
}
private void setupUI()
{
mMediaPlayer = new MediaPlayer();
mSurface = (SurfaceView) findViewById(R.id.surface);
SurfaceHolder holder = mSurface.getHolder();
holder.addCallback(this);
mTour = (Button) findViewById(R.id.tour);
mLogin = (Button) findViewById(R.id.login);
mTour.setOnClickListener(this);
mLogin.setOnClickListener(this);
}
@Override
public void surfaceCreated(SurfaceHolder holder)
{
startVideo(holder);
}
@SuppressLint("NewApi")
public void startVideo(SurfaceHolder holder)
{
String path = "android.resource://" + getPackageName() + BG_VIDEO_PATH;
Uri uri = Uri.parse(path);
try
{
android.view.ViewGroup.LayoutParams lp = mSurface.getLayoutParams();
mMediaPlayer.setDisplay(holder);
mMediaPlayer.setDataSource(this, uri);
mMediaPlayer.setVideoScalingMode(MediaPlayer.VIDEO_SCALING_MODE_SCALE_TO_FIT_WITH_CROPPING);
mMediaPlayer.setLooping(true);
mMediaPlayer.setOnPreparedListener(new OnPreparedListener()
{
@Override
public void onPrepared(MediaPlayer mp)
{
mHandler.postDelayed(new Runnable()
{
@Override
public void run()
{
mMediaPlayer.start();
}
}, VIDEO_START_HACK_DELAY);
}
});
mMediaPlayer.prepareAsync();
}
catch (Exception e)
{
Log.e("VID", "Problem starting video bg", e);
}
}
@Override
public void surfaceChanged(SurfaceHolder holder, int format, int width, int height)
{
// TODO Auto-generated method stub
}
@Override
public void surfaceDestroyed(SurfaceHolder holder)
{
// TODO Auto-generated method stub
}
@Override
public void onBackPressed()
{
mSurface.setVisibility(View.INVISIBLE);
mMediaPlayer.stop();
super.onBackPressed();
}
@Override
protected void onDestroy()
{
mMediaPlayer.stop();
mMediaPlayer.release();
super.onDestroy();
}
}
Here is layout file:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<SurfaceView
android:id="@+id/surface"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_marginBottom="40dp"
android:gravity="center"
android:orientation="vertical" >
<Button
android:id="@+id/tour"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:textAppearance="@style/Base.TextAppearance.AppCompat.Medium"
android:padding="10dp"
android:text="@string/ma_tour"/>
<Button
android:id="@+id/login"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:padding="10dp"
android:textAppearance="@style/Base.TextAppearance.AppCompat.Medium"
android:text="@string/ma_log_in"/>
</LinearLayout>
</RelativeLayout>
Target sdk is set to 22. Have you maybe experienced such behavior and can give any advice?
