推荐答案

Override onTouchEvent 在您的 WebView 中.
它适用于所有情况.

Override the onTouchEvent in your WebView.
It works in all cases.

@Override
public boolean onTouchEvent( MotionEvent event ) {

    if (event.getAction() == MotionEvent.ACTION_UP) {

        event.setAction(MotionEvent.ACTION_CANCEL);
        super.onTouchEvent(event);
        event.setAction(MotionEvent.ACTION_DOWN);
        super.onTouchEvent(event);
        event.setAction(MotionEvent.ACTION_UP);
    }

return super.onTouchEvent(event);
}
