Question

I’m setting up a frame layout that has two views – one is an ImageView and the other is a camera preview. Here’s the code:

public void setUpCamera(){
    //Set cameraView as the camera preview class
    cameraView = new CameraPreview(getApplicationContext());
    //Set imageResult as an image
    imageResult = new ImageView(getApplicationContext());

    imageResult.setBackgroundColor(Color.GRAY);

    //Prime the frame and buttons from the xml file
    frameLayout = (FrameLayout) findViewById(R.id.camera_preview);
    snapPhoto = (Button) findViewById(R.id.button_capture);

    //Add both camera preview and the snapped picture to the FrameLayout in the xml file 
    frameLayout.addView(imageResult);
    frameLayout.addView(cameraView);

    frameLayout.bringChildToFront(imageResult);

Now my question is whether it’s possible to add the cameraView “invisibly” to the FrameLayout? It’s a small thing, but otherwise when the camera is set up you get a flash of the camera preview mode before the image is brought to the fore by the bringChildToFront method.

Any ideas would be much appreciated!

Answer 1

Are you after setVisibility(View.GONE) or setVisibility(View.INVISIBLE) ?

GONE adjusts your layout as if the View wasn’t completely missing, INVISIBLE maintains any spacing.
