android 电视盒子 遥控器 获取,Android TV开发中所有的遥控器按键监听及注意事项，新增home键监听...

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;

case KeyEvent.KEYCODE_VOLUME_MUTE: //禁用声音

Log.d(TAG,"voice mute--->");

break;

break;

default:

break;

}

return super.onKeyDown(keyCode, event);

}

}

效果如下：

home键的监听要监听广播：

class HomeRecaiver extends BroadcastReceiver{

@Override

public void onReceive(Context context, Intent intent) {

String action = intent.getAction();

if(action.equals(Intent.ACTION_CLOSE_SYSTEM_DIALOGS)){

String reason = intent.getStringExtra(SYSTEM_DIALOG_REASON_KEY);

if(SYSTEM_DIALOG_REASON_HOME_KEY.equals(reason)){

Toast.makeText(MainActivity.this,"home键触发",0).show();

Log.d(TAG, "home键触发");

}

}

}

}

在oncreate()注册广播

public final String SYSTEM_DIALOG_REASON_KEY = "reason";

public final String SYSTEM_DIALOG_REASON_HOME_KEY = "homekey";

/**

* 注册广播

*/

private void initReceiver() {

homeReceiver = new HomeRecaiver();

IntentFilter filter = new IntentFilter(Intent.ACTION_CLOSE_SYSTEM_DIALOGS);

registerReceiver(homeReceiver, filter);

}

退出注销广播

@Override

protected void onDestroy() {

super.onDestroy();

if(homeReceiver!=null){

unregisterReceiver(homeReceiver);

}

}
