收到C2DM推送通知时更改活动行为

我有一个有效的服务器/客户端解决方案,可以向我的设备发送推送通知。我的项目的下一步是在C2DMReceiver类中调用onReceive事件时在活动窗口上显示一个对话框。

由于我是Android的新手,我不知道如何做到这一点,所以如果有人能向我解释,我会很高兴。

基本上我重用了chrometophone Application for c2dm中的类。调用onReceive事件,因为我为logcat创建了一个日志条目。由于C2DMReceiver是一项服务,如果有新消息,如何通知我的活动?

我google了很多但找不到合适的解决方案......我试图使用registerReceiver(),但我很确定我做错了。有人有例子吗?

好的,所以这是我到目前为止所得到的:

活动

    BroadcastReceiver mReceiver = new BroadcastReceiver() {
      public void onReceive(Context context, Intent intent) {
        Log.w(Consts.LOG_TAG_SERVICE, "Test");
      }
    };

    // Called when the activity is first created.
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Log.w(Consts.LOG_TAG_SERVICE, "started");

    }

    // Called when the activity is restarted
    protected void onResume() {
        super.onResume();

        IntentFilter filter = new IntentFilter();
        filter.addCategory("com.mydomain.myapp.CONTEXT");

        registerReceiver(mReceiver, filter);
    }

    // Called when the activity is closed
    protected void onPause() {
        super.onPause();

        unregisterReceiver(mReceiver);
    }

C2DMReceiver 公共类C2DMReceiver扩展了C2DMBaseReceiver {

public C2DMReceiver() {
    super("my_test@gmail.com");

    // TODO Load dynamic Gmail address
}

@Override
public void onRegistrered(Context context, String registrationId) {
    Log.i(Consts.LOG_TAG_SERVICE, registrationId);

    // Store the registration id in the preferences
    SharedPreferences settings = Prefs.get(context);
    SharedPreferences.Editor editor = settings.edit();
    editor.putString("deviceRegistrationID", registrationId);
    editor.commit();

    // TODO: Send ID to server
}

@Override
public void onUnregistered(Context context) {
    Log.w(Consts.LOG_TAG_SERVICE, "got here!");
}

@Override
public void onError(Context context, String errorId) {
    Log.w(Consts.LOG_TAG_SERVICE, errorId);
}

@Override
protected void onMessage(Context context, Intent intent) {
    Log.w(Consts.LOG_TAG_SERVICE, "C2DMReceiver: " + intent.getStringExtra("payload"));

    Intent broadcastIntent = new Intent();
    broadcastIntent.setAction("com.mydomain.myapp.NEWMESSAGE");
    broadcastIntent.putExtra("reading", intent.getStringExtra("payload"));
    broadcastIntent.addCategory("com.mydomain.myapp.CONTEXT");
    context.sendBroadcast(broadcastIntent);

}

}

这就是我所得到的,但我从未接收过自己的广播..有没有人有一些投入?

这应该这样做。

@Override
protected void onMessage(Context context, Intent intent) {

  Log.w(Consts.LOG_TAG_SERVICE, "C2DMReceiver: " + intent.getStringExtra("payload"));

  Intent i = new Intent(context, YourMainActivity.class);
  i.putExtra("reading", intent.getStringExtra("payload"));
  i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
  context.startActivity(i);

}

然后,您可以在主要活动中处理onStart中的意图。如果您的活动已在运行,它将由现有实例处理,否则将启动新实例。
