Android TV开发中所有的遥控器按键监听及注意事项

简单记录下android 盒子开发遥控器的监听 ，希望能帮到新入门的朋友们

不多说，直接贴代码

public class MainActivity extends Activity {

    private String  TAG="key";
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    @Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {

        switch (keyCode) {

           case KeyEvent.KEYCODE_ENTER:     //确定键enter
           case KeyEvent.KEYCODE_DPAD_CENTER:
               Log.d(TAG,"enter--->");

              break;

           case KeyEvent.KEYCODE_BACK:    //返回键
               Log.d(TAG,"back--->");

               return true;   //这里由于break会退出，所以我们自己要处理掉 不返回上一层

           case KeyEvent.KEYCODE_SETTINGS: //设置键
               Log.d(TAG,"setting--->");

               break;

           case KeyEvent.KEYCODE_DPAD_DOWN:   //向下键

                /*    实际开发中有时候会触发两次，所以要判断一下按下时触发 ，松开按键时不触发
                 *    exp:KeyEvent.ACTION_UP
                 */
                 if (event.getAction() == KeyEvent.ACTION_DOWN){   

                    Log.d(TAG,"down--->");
                }

                 break;

           case KeyEvent.KEYCODE_DPAD_UP:   //向上键
               Log.d(TAG,"up--->");

               break;

           case     KeyEvent.KEYCODE_0:   //数字键0
               Log.d(TAG,"0--->");

               break;

           case KeyEvent.KEYCODE_DPAD_LEFT: //向左键

               Log.d(TAG,"left--->");

               break;

           case KeyEvent.KEYCODE_DPAD_RIGHT:  //向右键
               Log.d(TAG,"right--->");
                break;

           case KeyEvent.KEYCODE_INFO:    //info键
               Log.d(TAG,"info--->");

               break;

           case KeyEvent.KEYCODE_PAGE_DOWN:     //向上翻页键
            case KeyEvent.KEYCODE_MEDIA_NEXT:
                  Log.d(TAG,"page down--->");

                break;


            case KeyEvent.KEYCODE_PAGE_UP:     //向下翻页键
            case KeyEvent.KEYCODE_MEDIA_PREVIOUS:
                  Log.d(TAG,"page up--->");

                break;

            case KeyEvent.KEYCODE_VOLUME_UP:   //调大声音键
                 Log.d(TAG,"voice up--->");

                break;

            case KeyEvent.KEYCODE_VOLUME_DOWN: //降低声音键
                 Log.d(TAG,"voice down--->");

                 break;
          default:
             break;
        }

        return super.onKeyDown(keyCode, event);

    }

}

效果如下：
