问题 I have a bunch of dynamically created ImageViews representing different objects in a game, which is working fine. However if any Image reaches the edge of the screen, it shrinks.

The gestureDetector is a member variable of the adapter-class. private GestureDetectorCompat gestureDetector;

问题 I have an apps that let the user to add text/image to the main image, and the main image can be zoomed.
