title: Draw rectangle Over ImageVIew
body: <p>I want to implement a crop feature, where I want to have a small rectangle over an imageView. The rectangle should be static and I want to move the image and get the image to be cropped within the rectangular area. Then fetch the image within the rectangle as an cropped image.
  I have tried creating a canvas using Bitmap as a parameter but it doesn't worked. I have tried a lot to search how to do this. but couldn't find it anywhere. Please help..</p>
  
  <pre><code>Bitmap bitmap=BitmapFactory.decodeResource(this.getResources(), R.drawable.indoor);
  
      Bitmap mutBitmap = Bitmap.createBitmap(200, 400,bitmap.getConfig());
  
      Canvas canvas = new Canvas(mutBitmap);
  
              Paint paint = new Paint();
              paint.setColor(Color.BLACK);
              paint.setStyle(Paint.Style.FILL_AND_STROKE);
              paint.setStrokeWidth(10);
              float leftx = 20;
              float topy = 20;
              float rightx = 50;
              float bottomy = 100;
              canvas.drawRect(leftx, topy, rightx, bottomy, paint);
  </code></pre>
  
  <p>I'm using the above code, but no rectangle is drawn on the imageView..</p>
