当简单地放置2个手指并将它们拖动一小段距离时。应用程序停止并存在。我在下面发布我的代码。这段代码是处理我的视图ontouchlistener的唯一一块。

ScrollView scrollView = (ScrollView) findViewById(R.id.ScrollView11);
        scrollView.setOnTouchListener(textIncreaseListener);
    }

    private OnTouchListener textIncreaseListener = new OnTouchListener() {

        public boolean onTouch(View v, MotionEvent event) {
            int count = event.getPointerCount();
            if(count == 2){
                Log.d(TAG, "2 pointers");
                return true;
            }
            return false;
        }
    };

任何帮助？

问题在于event.getPointerCount（），将此行放入try catch块或只是添加一个日志，你会发现它。你想用这个scrollView做什么。
