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 found that I was returning true for all events, where I should only have been returning it for the code that I was using. I moved the return true inside the scope of the if statement and returned false otherwise That brought my menu back!

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    super.onKeyDown(keyCode, event);
    if (keyCode == KeyEvent.KEYCODE_BACK) {
        dba.close();
        Intent result = new Intent("Complete");
        setResult(Activity.RESULT_OK, result);
        finish();
        return true;
    }
    return false;
}
