Answer 1

This will (most probably) create an image from 4, 5, 6 etc. points that you click manually on the ImageView to obtain. This should work on more than 4 points selected.

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

    ImageView imageView = (ImageView) findViewById(R.id.img);
    compositeImageView = (ImageView) findViewById(R.id.imageView);

    Bitmap bitmap1=BitmapFactory.decodeResource(getResources(), R.drawable.drawable_android);
    Bitmap bitmap2=BitmapFactory.decodeResource(getResources(), R.drawable.drawable_android_cr);

    Bitmap resultingImage=Bitmap.createBitmap(320, 480, bitmap1.getConfig());
    Canvas canvas = new Canvas(resultingImage);

    Paint paint = new Paint();
    paint.setAntiAlias(true);
    Path path=new Path();

    imageView.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            if (event.getAction() == MotionEvent.ACTION_DOWN){
                // textView.setText("Touch coordinates : " +String.valueOf(event.getX()) + "x" + String.valueOf(event.getY()));
                Log.e("X",String.valueOf(event.getX())+"");
                Log.e("y",String.valueOf(event.getY())+"");
                path.lineTo(String.valueOf(event.getX()), String.valueOf(event.getY()));
            }
            if(/*Touch count == 4 or 5 or 6 etc.*/){
                canvas.drawPath(path, paint);
                paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
                canvas.drawBitmap(bitmap2, 0, 0, paint);
                compositeImageView.setImageBitmap(resultingImage);
                return true;
            }
        }
    });
}
