textureview onSurfaceTextureAvailable never called inside relativelayout inside fragment
<p>onSurfaceTextureAvailable in VideoView is never called...<br>
I have this view that is holding the textureview.</p>

<pre><code>public class MyMediaPlayer extends RelativeLayout{

Context mContext;
VideoView player;//this is a custom textureview that streams video

public MyMediaPlayer(Context context) {
    super(context);
    mContext = context; 
    init();
}
public MyMediaPlayer(Context context, AttributeSet attrs) {
    super(context, attrs);
    mContext = context; 
    init();
}
public MyMediaPlayer(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
    mContext = context; 
    init();
}
private void init() {
    setBackgroundColor(Color.BLACK);    
    player = new VideoView(mContext);
    LayoutParams lp = new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
    addView(player,lp);
}
public void setURL(String url){
    player.setVideoPath(url);
}
public void start(){
    player.start();
}

}
</code></pre>

<p>VideoView is set up like this:</p>

<pre><code>public class VideoView extends TextureView {

public VideoView(final Context context) {
    super(context);
    mContext = context;
    initVideoView();
}

public VideoView(final Context context, final AttributeSet attrs) {
    super(context, attrs);
    mContext = context;
    initVideoView();
}

public VideoView(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
    mContext = context;
    initVideoView();
}

public void initVideoView() {
    Log.d(LOG_TAG, "Initializing video view.");
    videoHeight = 0;
    videoWidth = 0;
    setFocusable(false);
    setSurfaceTextureListener(surfaceTextureListener);
}
SurfaceTextureListener surfaceTextureListener = new SurfaceTextureListener() {
    @Override
    public void onSurfaceTextureAvailable(final SurfaceTexture surface, final int width, final int height) {
        Log.d(LOG_TAG, "Surface texture now avaialble.");
        surfaceTexture = surface;
        openVideo();
    }

    @Override
    public void onSurfaceTextureSizeChanged(final SurfaceTexture surface, final int width, final int height) {
        Log.d(LOG_TAG, "Resized surface texture: " + width + '/' + height);
        surfaceWidth = width;
        surfaceHeight = height;
        boolean isValidState =  (targetState == STATE_PLAYING);
        boolean hasValidSize = (videoWidth == width &amp;&amp; videoHeight == height);
        if (mediaPlayer != null &amp;&amp; isValidState &amp;&amp; hasValidSize) {
            start();
        }
    }

    @Override
    public boolean onSurfaceTextureDestroyed(final SurfaceTexture surface) {
        Log.i(LOG_TAG, "Destroyed surface number " + number);
        return false;
    }

    @Override
    public void onSurfaceTextureUpdated(final SurfaceTexture surface) {

    }
};
}

<p>MyMediaPlayer is setup in a xml of a fragment.<br>
If i place the VideoView inside the fragment then everything works fine.<br>
But if it is in mymediaplayer inside the fragment onSurfaceTextureAvailable is never called.</p>
