我可以简单地模拟单个触摸 - 在我的测试中点击,滑动,按住等,但完全坚持使用Android 2.2在HTСDesire上模拟多点触控。
您能告诉我,如何重现事件链以测试多点触摸?
我想我需要使用一些棘手的MotionEvent,比如MASK或类似的东西,但不知道怎么做。
我在这里发现了转载缩放事件的转储: http://www.zdnet.com/blog/burnette/how-to-use-multi-touch-in-android-2-part-3-understanding-touch-events/1775?tag=mantle_skin;content
1. event ACTION_DOWN[#0(pid 0)=135,179]
2. event ACTION_MOVE[#0(pid 0)=135,184]
3. event ACTION_MOVE[#0(pid 0)=144,205]
4. event ACTION_MOVE[#0(pid 0)=152,227]
5. event ACTION_POINTER_DOWN(pid 1)[#0(pid 0)=153,230;#1(pid 1)=380,538]
6. event ACTION_MOVE[#0(pid 0)=153,231;#1(pid 1)=380,538]
7. event ACTION_MOVE[#0(pid 0)=155,236;#1(pid 1)=364,512]
8. event ACTION_MOVE[#0(pid 0)=157,240;#1(pid 1)=350,498]
9. event ACTION_MOVE[#0(pid 0)=158,245;#1(pid 1)=343,494]
10. event ACTION_POINTER_UP(pid 0)[#0(pid 0)=158,247;#1(pid 1)=336,484]
11. event ACTION_MOVE[#0(pid 1)=334,481]
12. event ACTION_MOVE[#0(pid 1)=328,472]
13. event ACTION_UP[#0(pid 1)=327,471]
这是我的问题:
如何生成4个坐标的事件(pid 0 x0 y0和pid 1 x1 y1)?
看起来我需要找到如何使用以下事件的方式:
public static MotionEvent获取(long downTime,long eventTime,int action,int pointers,int [] pointerIds,PointerCoords [] pointerCoords,int metaState,float xPrecision,float yPrecision,int deviceId,int edgeFlags,int source,int flags )
感谢Dan的回复,我尝试了这个逻辑,但仍然遇到了添加坐标的问题:
MotionEvent event = MotionEvent.obtain(downTime, eventTime, MotionEvent.ACTION_DOWN, 135, 179, 0);
inst.sendPointerSync(event);
// eventTime+=100;
event = MotionEvent.obtain(downTime, eventTime, MotionEvent.ACTION_MOVE, 135, 184, 0);
inst.sendPointerSync(event);
// eventTime+=100;
int pointerToMove = 1; // pointer IDs are zero-based
event = MotionEvent.obtain(downTime, eventTime, (pointerToMove << MotionEvent.ACTION_POINTER_INDEX_SHIFT) + MotionEvent.ACTION_POINTER_DOWN, 138, 189, 0);
inst.sendPointerSync(event);
event = MotionEvent.obtain(downTime, eventTime, (pointerToMove << MotionEvent.ACTION_POINTER_INDEX_SHIFT) + MotionEvent.ACTION_MOVE, 158, 220, 0);
inst.sendPointerSync(event);
// eventTime+=100;
event = MotionEvent.obtain(downTime, eventTime, (2 * 256) + MotionEvent.ACTION_MOVE, 138, 180, 0);
inst.sendPointerSync(event);
// eventTime+=100;
event = MotionEvent.obtain(downTime, eventTime, MotionEvent.ACTION_MOVE, 135, 184, 0);
这些事件序列在我的测试存根中捕获并转储为:
(14368): event ACTION_DOWN[#0(pid 0)=135,179]
(14368): event ACTION_MOVE[#0(pid 0)=135,184]
(14368): event ACTION_POINTER_DOWN(pid 1)[#0(pid 0)=138,189]
(14368): event ACTION_MOVE[#0(pid 0)=158,220]
(14368): event ACTION_MOVE[#0(pid 0)=138,180]
(14368): event ACTION_MOVE[#0(pid 0)=135,184]
在这里你可以看到,那 (2 * 256)+ MotionEvent.ACTION_MOVE 不会更改事件的指针ID :( 和 pointerToMove&lt;&lt; MotionEvent.ACTION_POINTER_INDEX_SHIFT 方法不适用于ACTION_POINTER_DOWN,可能是我不允许以这种方式使用POINTER_DOWN?
我的问题是我无法为指针0和指针1生成2对坐标:
(14368): event ACTION_POINTER_DOWN(pid 1)[#0(pid 0)=138,189]
在这里你可以看到,使用你的逻辑我已经将pid1添加到事件中,但它仍然没有坐标,因为x和y与pid 0相关联。
提前谢谢。

仍然没有想法如何实现它,有人发过多点触控事件吗?

我相信你只需要在传递给MotionEvent.obtain的'action'参数中指出指针索引。具体地,动作的高8位是指针索引,低8位是动作(例如,MotionEvent.ACTION_MOVE)。所以,如果你想移动第二个指针,这应该有效:
int pointerToMove = 1; // pointer IDs are zero-based
event = MotionEvent.obtain(downTime, eventTime, (pointerToMove << MotionEvent.ACTION_POINTER_INDEX_SHIFT) + MotionEvent.ACTION_MOVE, x0, y0, 0);
inst.sendPointerSync(event);
