上面是搜索到的方法，值得看看，下面是我在做悬浮球时模拟截屏，和锁屏的功能，感谢李工：

 private void sendDownEvents(int keyCode) {
   final long token = Binder.clearCallingIdentity();
 
   // Inject down.
   final long downTime = SystemClock.uptimeMillis();
   KeyEvent down = KeyEvent.obtain(downTime, downTime, KeyEvent.ACTION_DOWN, keyCode, 0, 0,
     KeyCharacterMap.VIRTUAL_KEYBOARD, 0, KeyEvent.FLAG_FROM_SYSTEM,
     InputDevice.SOURCE_KEYBOARD, null);
   InputManager.getInstance().injectInputEvent(down,
     InputManager.INJECT_INPUT_EVENT_MODE_ASYNC);
   down.recycle();
 
   Binder.restoreCallingIdentity(token);
  }

 private void sendUpEvents(int keyCode) {
   final long token = Binder.clearCallingIdentity();
 
   // Inject down.
   final long downTime = SystemClock.uptimeMillis();
   KeyEvent up = KeyEvent.obtain(downTime, downTime, KeyEvent.ACTION_UP, keyCode, 0, 0,
     KeyCharacterMap.VIRTUAL_KEYBOARD, 0, KeyEvent.FLAG_FROM_SYSTEM,
     InputDevice.SOURCE_KEYBOARD, null);
   InputManager.getInstance().injectInputEvent(up,
     InputManager.INJECT_INPUT_EVENT_MODE_ASYNC);
   up.recycle();
 
   Binder.restoreCallingIdentity(token);
  }
 public void screenShot() {
  sendDownEvents(KeyEvent.KEYCODE_VOLUME_DOWN);
  sendDownEvents(KeyEvent.KEYCODE_POWER);
  try {
   Thread.sleep(600);
  } catch (InterruptedException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }
  sendUpEvents(KeyEvent.KEYCODE_VOLUME_DOWN);
  sendUpEvents(KeyEvent.KEYCODE_POWER);
 }
 public void lockScreen2(){
     sendDownEvents(KeyEvent.KEYCODE_POWER);
    sendUpEvents(KeyEvent.KEYCODE_POWER);
 }
