How to add functionality to the official Take Photo Button on Android phones?

Question

I need to add functionality to this button, but I don’t know the name of the button, and I don’t know how to give it functionality.

Does anyone know what to do?

SOLVED:

    mSurfaceView.requestFocus();
    mSurfaceView.setFocusableInTouchMode(true);

public boolean onKey(View v, int keyCode, KeyEvent event) {
    boolean keyManaged=false;
    switch(keyCode)
    {
        case KeyEvent.KEYCODE_CAMERA:
            mCamera.takePicture(null, mPictureCallback, mPictureCallback);  
            keyManaged=true;
            break;
    }
    return keyManaged;
}

Answer 1

It is displayed as KeyEvent.KEYCODE_CAMERAin KeyListener .

Answer 2

If you need this while your application is active, you can simply register OnKeyListenerand check the event KeyEvent.ACTION_DOWN.
