1. 事件类型
MotionEvent.ACTION_DOWN
MotionEvent.ACTION_MOVE
MotionEvent.ACTION_UP
2. 事件传递
public boolean onTouch(View v, MotionEvent event) {
return false; //表示事件没有触发成功，是不会有后续事件的
return true; // 要想处理后续事件，需要返回true
}
3. 获取多个触摸点坐标
public boolean onTouch(View v, MotionEvent event) {
// TODO Auto-generated method stub
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
break;
case MotionEvent.ACTION_MOVE:
Log.d(TAG, "getPointerCount = " + event.getPointerCount());
//
Log.d(TAG, "point1: x=" + event.getX(0) + ", y=" + event.getX(0));
Log.d(TAG, "point2: x=" + event.getX(1) + ", y=" + event.getX(1));
Log.d(TAG, "point3: x=" + event.getX(2) + ", y=" + event.getX(2));
break;
case MotionEvent.ACTION_UP:
break;
default:
break;
}
return true;
}
