onKeyDown() issue

Question

I would like to create a photo/video capture application.

I have created a CaptureView class which extends SurfaceView and placed it in the main form.

The main form's activity has onCreateOptionsMenu() method which creates a menu. The menu worked fine but then I tried to implement a method onKeyDown:

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {

    if(event.getAction() == KeyEvent.ACTION_DOWN) {
        switch(keyCode) {
        case KeyEvent.KEYCODE_CAMERA:
            videoPreview.TakePicture();
            return true;
        }
    }

    return super.onKeyDown(keyCode, event);
}

The menu doesn't appear anymore and the method doesn't catch onKeyDown event.

Does anyone know what could be the reason for this issue?

Answer 1

I had a similar problem and solved it by adding

this.requestFocus();
this.setFocusableInTouchMode(true);

in the constructor of my SurfaceView subclass.
