林现在正在寻找2周，但没有成功的解决方案。 这个问题很简单。我模拟了DPAD事件（上，下，左，右，中心）进行导航在我的GUI这就是由大量的按钮和其他元素。随着模拟D-垫我可以不带线code浏览抛出这个GUI。但是，我怎么能做到这一点编程？

Im searching now for 2 weeks for a solution with no success. The problem is very simple. I have to simulate the dpad events (UP,DOWN,RIGHT,LEFT,CENTER) for navigate in my GUI thats consist of a lot of buttons and other elements. With the simulator D-Pad i can without a line code navigate throw this GUI. But how can i do this programmatically?

我已经尝试了很多，但没有成功：

I have tried a lot with no success:

KeyEvent的事件=新的KeyEvent（KeyEvent.ACTION_DOWN，KeyEvent.KEY code_DPAD_LEFT）;        View.dispatchKeyEvent（事件）; 没有发生（重点应该转移的一个元素右）

KeyEvent event = new KeyEvent(KeyEvent.ACTION_DOWN,KeyEvent.KEYCODE_DPAD_LEFT); View.dispatchKeyEvent(event); Nothing happen (the focus should move one element to right)

我也看到了很多关于windowManager.injectKeyEvent，但没有找到工作的。

I have also read a lot about windowManager.injectKeyEvent but nothing found that works.

我觉得有一个解决方案，因为对讲系统可以模拟物理方向键（http://$c$c.google.com/p/eyes-free/source/browse/trunk/ime/latinime/src/com/google$c$c/eyesfree/inputmethod/latin/LatinIME.java)

I think there is a solution, because talkback can simulate the physical D-Pad (http://code.google.com/p/eyes-free/source/browse/trunk/ime/latinime/src/com/googlecode/eyesfree/inputmethod/latin/LatinIME.java)

推荐答案

我找到了聪明的解决方案（例如下去）：

I found the smart solution (e.g for go down):

bic=new BaseInputConnection(this.getWindow().getDecorView(),false);
KeyEvent event2 = new KeyEvent(0, 0, KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_DPAD_DOWN,0, KeyEvent.META_SYM_ON, 0, 0, KeyEvent.FLAG_VIRTUAL_HARD_KEY); 

bic.sendKeyEvent(event2);

这就是所有，内部algortihm发现在你选择的方向下一个元素

Thats all, an internal algortihm find the next element in your selected direction
