Question

iv.setOnTouchListener(new OnTouchListener() {

        @Override
        public boolean onTouch(View v, MotionEvent event) {
            // AB| = √[(x₁-x₂)²+(y₁-y₂)²]，换成x₂-x₁和y₂-y₁
            switch (event.getAction()) {
            case MotionEvent.ACTION_DOWN:
                if ((event.getX() > -width / 2 || event.getX() < width / 2)
                        && (event.getY() < -height / 2
                        || event.getY() >height / 2)) {
                    stoptdonghua();
                }else{ 
                    stoptdonghua();
                    }
                break;
            case MotionEvent.ACTION_UP:
                if ((event.getX() > -width / 2 || event.getX() < width / 2)
                        && (event.getY() < -height / 2
                        || event.getY() > height / 2)){ 
                    stoptdonghua();
                }else{ 
                    stoptdonghua();
                }
                break;

            default:
                break;
            }
            return false;
        }
    });

说明表达式里返回值为true，需要检查一下event.getX()和width的值是不是预期想要的！
