You need to remove this function for clickable to childview

it doesn't work for me ，in my case ，childView’s click event area is not change after scaled ,
For example, after the ViewGroup is zoomed in, the click event area of ​​the child View is still the area before the zoom, resulting in the click being unavailable.

@guvencan
The ViewGroup is scaled by dispatchDraw, which is equivalent to the actual position of the child View. The position of the click event after zooming in or out is incorrect. Is there any other solution? Thank you

Because view translating in dispatchDraw function for save position on the screen but view position will be changed. For example your view position is (100, 100) in 1x scale, after scaled 2x position is (50,50) but object stay same place on the screen. You can use TapInfo class for the follow position.

Main issue it this, every ZoomLayout's 'onTouchEvent' handled. It should handle child view 'onTouchEvent' at first.
For example,
We have 3 CustomViews with touch to draw.
When we touch on screen, it should first handle top most view's 'onTouchEvent', if it fails (like view is disabled, or not active), then 2nd from top, and so on. If no view handles 'onTouchEvent' then it must be handles by 'ZoomLayout'.
