在我正在处理的应用中,每当用户收到消息时,消息内容都会使用BroadcastReceiver
传递到应用。我想为这个意图添加一个字段并获得一些额外的信息,只是不知道意图来自何处。
这是广播及其onReceive()
方法:
br = new BroadcastReceiver() {
public void onReceive(Context context, Intent intent) {
int task = intent.getIntExtra(PARAM_TASK, 0);
int status = intent.getIntExtra(PARAM_STATUS, 0);
int msgId = intent.getIntExtra("msgId", 0);
long msgFromUserId = intent.getLongExtra("msgFromUserId", 0);
int msgFromUserState = intent.getIntExtra("msgFromUserState", 0);
int msgFromUserVerify = intent.getIntExtra("msgFromUserVerify", 0);
String msgFromUserUsername = intent.getStringExtra("msgFromUserUsername");
String msgFromUserFullname = intent.getStringExtra("msgFromUserFullname");
String msgFromUserPhotoUrl = intent.getStringExtra("msgFromUserPhotoUrl");
String msgMessage = intent.getStringExtra("msgMessage");
String msgImgUrl = intent.getStringExtra("msgImgUrl");
int msgCreateAt = intent.getIntExtra("msgCreateAt", 0);
String msgDate = intent.getStringExtra("msgDate");
String msgTimeAgo = intent.getStringExtra("msgTimeAgo");
int msgTransactionValue = intent.getIntExtra("transValue",0);
Chat1Item c = new Chat1Item();
c.setId(msgId);
c.setFromUserId(msgFromUserId);
c.setFromUserState(msgFromUserState);
c.setFromUserVerify(msgFromUserVerify);
c.setFromUserUsername(msgFromUserUsername);
c.setFromUserFullname(msgFromUserFullname);
c.setFromUserPhotoUrl(msgFromUserPhotoUrl);
c.setMessage(msgMessage);
c.setImgUrl(msgImgUrl);
c.setCreateAt(msgCreateAt);
c.setDate(msgDate);
c.setTimeAgo(msgTimeAgo);
c.setTransactionValue(msgTransactionValue);
Log.e(LOG_TAG, "onReceive: task = " + task + ", status = " + status + " " + c.getMessage() + " " + Integer.toString(c.getId()));
final Chat1Item lastItem = (Chat1Item)
listView.getAdapter().getItem(listView.getAdapter().getCount() - 1);
messagesCount = messagesCount + 1;
chat1List.add(c);
if (!visible) {
try {
Uri notification =
RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
Ringtone r = RingtoneManager.getRingtone(getActivity(), notification);
r.play();
} catch (Exception e) {
e.printStackTrace();
}
}
chatAdapter.notifyDataSetChanged();
scrollListViewToBottom();
getNextMessages();
}
它还使用IntentFilter注册BroadcastReceiver
:
IntentFilter intFilt = new IntentFilter(BROADCAST_ACTION);
getActivity().registerReceiver(br, intFilt);
这些也是我的清单文件中的intent-filters:
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<service
android:name="com.thetasocial.app.service.MyFcmListenerService">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT" />
</intent-filter>
</service>
<service
android:name="com.thetasocial.app.service.MyInstanceIDListenerService">
<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT" />
</intent-filter>
</service>
<service
android:name="com.thetasocial.app.service.MyService"
android:exported="false" />
给我一个从头开始的线索。提前谢谢。

找到sendBroadcast文件或项目......在那里你会看到BroadcastReciever广播的意图和意图内容......
答案 1 :(得分:0)
首先,这是本地广播接收器。即,匿名类,因此您无法在manifest.xml
中找到该接收器。该接收器必须是注册和未注册的,这是强制性的,并且必须在该特定活动(或)片段中完成,在注册(或)注销代码中,我们可以找到广播意图过滤器名称。在您的情况下,BROADCAST_ACTION
是名称。尝试在整个项目中查找BROADCAST_ACTION
的用法。要查找整个项目的用法,如果您使用的是Android工作室,则快捷方式为ctrl
+ shift
+ F
。您的广播意图如下所示,
Intent intent = new Intent(BROADCAST_ACTION);
sendBroadcast(intent);
注意,如果在某处声明了常量值,则intent过滤器名称只是一个字符串BROADCAST_ACTION
。
希望这有用:)
