Getting image from SurfaceView to ImageView?
<p>I'm having a little trouble of getting an image/drawable or a bitmap from a SurfaceView that works as a camera preivew.</p>

<pre><code>    final CameraSurfaceView cameraSurfaceView = new CameraSurfaceView(this);
    LinearLayout ll = (LinearLayout)findViewById(R.id.linearLayout1);
    ll.addView(cameraSurfaceView); // THIS WORKS

    ImageView ivCam = (ImageView) findViewById(R.id.ivCam);
    ivCam.setImageBitmap(cameraSurfaceView.getDrawingCache()); // THIS DOESN'T :(
</code></pre>

<p>Any suggestions? Thanks!</p>

<p>EDIT:</p>

<pre><code>    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        final CameraSurfaceView cameraSurfaceView = new CameraSurfaceView(this);
        LinearLayout ll = (LinearLayout)findViewById(R.id.LLS);
        ll.addView(cameraSurfaceView); // THIS WORKS


    }
