    text
    copied!<p>I have a FrameLayout containing two SurfaceViews. One of them will show the camera preview, and the other is a custom surface view I use for drawing. Problem is the surface view does not show up. If I comment out the line where the camera starts preview, it does though, on the black background. This indicates me that the Surface view is positioned well, but I suspect that when the camera preview draws, something goes wrong.</p> <p>The camera view:</p> <pre><code>public CameraView(Context context, AttributeSet a) { super(context, a); mHolder = getHolder(); mHolder.addCallback(this); mHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); } </code></pre> <p>The custom view:</p> <pre><code>public InclinaisonGauge(Context context, AttributeSet attrs) { super(context, attrs); getHolder().addCallback(this); getHolder().setFormat(PixelFormat.TRANSLUCENT); } @Override public void surfaceCreated(SurfaceHolder holder) { run = true; updateThread = new Thread() { public void run() { Canvas c = null; final SurfaceHolder inclHolder = getHolder(); while (run) { try { c = inclHolder.lockCanvas(); if(c!=null) { synchronized (inclHolder) { onDraw(c); } } } finally { // do this in a finally so that if an exception is thrown // during the above, we don't leave the Surface in an // inconsistent state if (c != null) { inclHolder.unlockCanvasAndPost(c); } } } } }; </code></pre> <p>And I use this very simple draw method on the custom view to make sure it is not a framerate issue</p> <pre><code>public void doDraw(final Canvas canvas, final boolean bigSize, float daDirection) { canvas.drawARGB(255, 255, 255, 255); } </code></pre> <p>Has anyone experienced this?</p> <p>Thanks</p>
