触摸事件移除 View 区域监听

1、在 down 时获取可检测区域

            case MotionEvent.ACTION_DOWN: {
                getDrawingRect(mOutRect);
                isPressed = true;
                break;
            }

2、move 时判断

            case MotionEvent.ACTION_MOVE: {
                if (!mOutRect.contains((int) event.getX(), (int) event.getY())) {
                    isPressed = false;
                    invalidatePaint();
                    invalidate();
                }
                break;
            }

Start by locating the Android View touch-handling entry point that processes MotionEvent.ACTION_DOWN and ACTION_MOVE; no file or test path is provided. Compare the existing pressed-state behavior with the supplied snippets. Done means the drawing rectangle is captured on down, moving outside clears the pressed state, and the view is invalidated.
