java - Android Studio Google Glass 模拟器中未检测到点击/滑动

Question

我正在运行一个谷歌眼镜模拟器，如下所示，通过显示设置、主显示屏甚至我的 Activity (我假装是交互式静态卡)，工作得非常完美。

我发现运动手势是使用 onKeyUp 或 onKeyDown 事件捕获的，但两者都不起作用我不明白为什么。

这是我的代码。

public class LiveCardMenuActivity extends Activity {

    private TextView textView;

    @Override //isn't catching a thing, even with onKeyDown (mouse taps or slides in the emulator)
    public boolean onKeyUp(int keycode, KeyEvent event){
        Log.d("tag","keyUp");
        if(keycode == KeyEvent.KEYCODE_DPAD_CENTER){
            Log.d("tag","keypadcenter");
            textView.setText("tap");
        }else if(keycode == KeyEvent.KEYCODE_BACK){
            Log.d("tag","swipedown");
            textView.setText("down");
        }
        return true;
    }

    @Override
    public void onAttachedToWindow() {
            super.onAttachedToWindow();
            setContentView(R.layout.live_card); 
            //does successfully, I can see the layout in the emulator
           //and I can swipe it to the left (returning to the main display successfully)
            textView = (TextView) findViewById(R.id.textView);
            Log.d("tag","attached to window");
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.live_card, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
            case R.id.action_stop:
                // Stop the service which will unpublish the live card.
                stopService(new Intent(this, LiveCardService.class));
                return true;
            default:
                return super.onOptionsItemSelected(item);
        }
    }

    @Override
    public void onOptionsMenuClosed(Menu menu) {
        super.onOptionsMenuClosed(menu);
        // Nothing else to do, finish the Activity.
        finish();
    }
}

有人可以帮我解决这个问题吗？泰姆!

尝试在内容 View 上调用 setFocusable(true)。

虽然我不太了解这个模拟器的工作原理，但这就是您如何让它在标准 Android 上工作的方法。
