android 向模拟发送多点触摸事件~

要向android发送系统多点触摸事件，发现网上有人问，但是没有人有答案~我也发过帖子没有人回答~搞了好久很搞出来~google真TMD不搞个文档，搞个例子~

贴下代码~下面是适合2.2的~

public boolean sendMoveDouble()

{

//point 1 release first

Log.i("key", "199199 send sendMovedoubl...........e");

Instrumentation inst = new Instrumentation();

MotionEvent e;

//nano

e=MotionEvent.obtainNano(SystemClock.uptimeMillis(),

SystemClock.uptimeMillis(), System.nanoTime(),

0, 1, new int[]{0},

new float[]{bx1, by1, 1, 1}, 0,

0, 0, 0, 0);

Log.i("key", "199199 send sendMovedoubl...........1");

inst.sendPointerSync(e);

SystemClock.sleep(200);//Ms

e=MotionEvent.obtainNano(SystemClock.uptimeMillis(),

SystemClock.uptimeMillis(), System.nanoTime(),

261, 2, new int[]{0, 1},

new float[]{bx1, by1, 1, 1, ex1, ey1, 1, 1}, 0,

0, 0, 0, 0);

Log.i("key", "199199 send sendMovedoubl...........2");

inst.sendPointerSync(e);

SystemClock.sleep(200);//Ms

e=MotionEvent.obtainNano(SystemClock.uptimeMillis(),

SystemClock.uptimeMillis(), System.nanoTime(),

2, 2, new int[]{0, 1},

new float[]{bx2, by2, 1, 1, ex2, ey2, 1, 1}, 0,

0, 0, 0, 0);

Log.i("key", "199199 send sendMovedoubl...........3");

inst.sendPointerSync(e);

SystemClock.sleep(200);//Ms

e=MotionEvent.obtainNano(SystemClock.uptimeMillis(),

SystemClock.uptimeMillis(), System.nanoTime(),

6, 2, new int[]{0, 1},

new float[]{bx2, by2, 1, 1, ex2, ey2, 1, 1}, 0,

0, 0, 0, 0);

inst.sendPointerSync(e);

SystemClock.sleep(200);//Ms

Log.i("key", "199199 send sendMovedoubl...........4");

e=MotionEvent.obtainNano(SystemClock.uptimeMillis(),

SystemClock.uptimeMillis(), System.nanoTime(),

1, 1, new int[]{1},

new float[]{bx2, by2, 1, 1}, 0,

0, 0, 0, 0);

Log.i("key", "199199 send sendMovedoubl...........5");

inst.sendPointerSync(e);

return true;

}

MotionEvent.obtainNano这个函数是2.2的，在SDK中没有，你必须有android的源码，在源码中编译才能链接到！在sdk中提示没有这个函数

利用这个代码我在2.2中成功的实现了放大和缩小
