我试图做一个聊天app.I有SlidingDrawer活动，它有很多碎片，其中ChatFragment是one.Now当我发短信给我的朋友，我有一个Chatting Window ，如果任何消息来自GCM服务我在ChatFragment则此消息会去那个片段，当我想更新chatWindow当任何消息来一边聊天一边现在我试图做类似下面的更新列表视图。
GcmIntentService：
public class GcmIntentService extends IntentService {
public GcmIntentService() {
super("GcmIntentService");
}
@Override
protected void onHandleIntent(Intent intent) {
Bundle extras = intent.getExtras();
GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);
// The getMessageType() intent parameter must be the intent you received
// in your BroadcastReceiver.
String messageType = gcm.getMessageType(intent);
if (extras != null && !extras.isEmpty()) { // has effect of unparcelling Bundle
// Since we're not using two way messaging, this is all we really to check for
if (GoogleCloudMessaging.MESSAGE_TYPE_MESSAGE.equals(messageType)) {
Logger.getLogger("GCM_RECEIVED").log(Level.INFO, extras.toString());
showToast(extras.getString("message"));
Intent sendData = new Intent("chatupdater");
sendData.putExtra("msg", extras.getString("message"));
LocalBroadcastManager.getInstance(this).sendBroadcast(sendData);
Log.i("chat","i am in GCMIntentService");
}
}
GcmBroadcastReceiver.completeWakefulIntent(intent);
}
在这里我开始一个BroadcastReceiver在onHandleIntent（）。
ChatBroadCastReceiver：
public class ChatBroadCastReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
Log.i("chat","I am in ChatBroadCastReceiver");
String msg = intent.getStringExtra("msg");
Log.i("chat",msg);
//Intent data = new Intent("chatupdater");
//Intent data = new Intent("chatupdater");
//data.putExtra("key","data");
//data.putInt("fragmentno",1); // Pass the unique id of fragment we talked abt earlier
//context.sendBroadcast(intent);
}
}
这是我的ChatBroadCastReceiver类如果有任何消息传出它成功地在接收onReceive() method.Now我想这个消息发送给我试过Fragment.What，我注册的片段与它试图让在同一数据onReceive()的ChatFragment 。但它并没有call.I试图通过记录看。
public class ChatFragment extends Fragment {
//ChatBroadCastReceiver mReceiver;
private EditText et_chat;
Bundle mailData;
String caller_mail;
private ListView chatListview;
private ChatWindowAdapter chatWindowAdapter;
private List<ChatSession>PreviousChatSession;
private List<ChatInfo> chatListItems;
Button chat_send;
public ChatFragment() {
}
public BroadcastReceiver mReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
Log.i("chat","I am in BroadCastReceiver");
String msg = intent.getStringExtra("msg");
Toast.makeText(getActivity(),msg,Toast.LENGTH_LONG).show();
}
};
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mReceiver = new ChatBroadCastReceiver();
//getActivity().registerReceiver(new ChatBroadCastReceiver(),new IntentFilter("chatupdater"));
LocalBroadcastManager.getInstance(getActivity()).registerReceiver(new ChatBroadCastReceiver(),new IntentFilter("chatupdater"));
Log.i("chat", "I am in onCreate");
}
现在，我怎样才能得到我在ChatFragment的广播接收器到的onReceive（）得到的消息？
