Android second layer on running camera app

Question

I´m new in Android programming and I want to program a simple App for practise. I already searched the web for hours, but didn´t find any answers for my problem.

I want to put a 2. layer above the running camera app.

If I take a picture, it shouldn´t show the 2. Layer in the Picture, like there was never a 2. Layer.

That´s the current code, only working camera. A picture shows how it could look like: http://www.bild.me/bild.php?file=91520242013-08-03_19-25-33.png

  public class MainActivity extends Activity {

    ImageView iv;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);        

        startCamera();

    }

    public void startCamera() {
        iv = (ImageView)findViewById(R.id.imageView);

        Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);

        startActivityForResult(intent, 0);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {

        if(requestCode == 0) {
            Bitmap theImage = (Bitmap) data.getExtras().get("date");
            iv.setImageBitmap(theImage);
            startCamera();
        }

    }


}

Take a look at: [How should I add elements to a custom camera android application?](http://stackoverflow.com/questions/17932989/how-should-i-add-elements-to-a-custom-camera-android-application/17933418#17933418) and [Is it possible to add buttons to a framelayout that was set programmatically?](http://stackoverflow.com/questions/17931151/is-it-possible-to-add-buttons-to-a-framelayout-that-was-set-programmatically/17931768#17931768) — Vikram, Aug 03 '13 at 17:56

If I understand you correctly, you want to put a 2 overlay on the preview area, but you don't want the 2 to show up on the final image.

IF this is correct, I recommend taking a look at this post: Android: Overlay on Android Camera Preview

Basically this will tell you how to draw an overlay on top of the CameraView. Look at the example on the examples page (the one called CameraPreview). http://developer.android.com/tools/samples/index.html
