我创建了一个 Activity ,它在通知发生时刷新,但我面临一个问题,即当通知到来时,它会继续发送无休止的相同通知。早些时候它工作正常,但我做了一些改变,这已经完成了。请帮我。我附上了我的代码。
GCM IntentService 类的代码
@Override
protected void onHandleIntent(Intent intent) {
Bundle extras = intent.getExtras();
String msgg = intent.getStringExtra("message");
final ResultReceiver receiver = intent.getParcelableExtra("receiver");
Bundle bundle = new Bundle();
if (!extras.isEmpty()) {
if (GoogleCloudMessaging.
MESSAGE_TYPE_SEND_ERROR.equals(messageType)) {
sendNotification(this, msgg);
} else if (GoogleCloudMessaging.
MESSAGE_TYPE_DELETED.equals(messageType)) {
sendNotification(this, msg);
updateMyActivity(this,msgg);
bundle.putString("result", msg);
receiver.send(STATUS_FINISHED, bundle);
} else if (GoogleCloudMessaging.
MESSAGE_TYPE_MESSAGE.equals(messageType)) {
updateMyActivity(this,msgg);
sendNotification(this, msg);
}
}
发送通知码
private void sendNotification(Context context, String message) {
Intent resultIntent;
int icon = R.mipmap.ic_launcher;
long when = System.currentTimeMillis();
NotificationCompat.Builder nBuilder;
Uri alarmSound = RingtoneManager
.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.BigPictureStyle notiStyle = new
NotificationCompat.BigPictureStyle();
notiStyle.setBigContentTitle("afewtaps");
notiStyle.setSummaryText(message);
nBuilder = new NotificationCompat.Builder(context)
.setSmallIcon(icon)
.setContentTitle("afewtaps")
.setStyle(new NotificationCompat.BigTextStyle().bigText(message))
.setLights(Color.BLUE, 500, 500).setContentText(message)
.setAutoCancel(true).setTicker("Notification from afewtaps")
.setSound(alarmSound);
resultIntent = new Intent(context,
LoginActivity.class);
resultIntent.putExtra("message", message);
resultIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent resultPendingIntent = PendingIntent.getActivity(context,
notify_no, resultIntent, PendingIntent.FLAG_UPDATE_CURRENT);
// Show the max number of notifications here
if (notify_no < 9) {
notify_no = notify_no + 1;
} else {
notify_no = 0;
}
nBuilder.setContentIntent(resultPendingIntent);
NotificationManager nNotifyMgr = (NotificationManager) context
.getSystemService(context.NOTIFICATION_SERVICE);
nNotifyMgr.notify(notify_no + 2, nBuilder.build());
}
发送消息进行广播
// This function will create an intent. This intent must take as parameter the "unique_name" that you registered your activity with
static void updateMyActivity(Context context, String message) {
Intent intent = new Intent("com.google.android.c2dm.intent.RECEIVE");
//put whatever data you want to send, if any
intent.putExtra("message", message);
//send broadcast
context.sendBroadcast(intent);
}
这结束了 Intent 类的代码。
现在我的 Activity 代码
@Override
public void onResume() {
super.onResume();
// connectToDatabase();
getActivity().registerReceiver(mMessageReceiver, new IntentFilter("com.google.android.c2dm.intent.RECEIVE"));
}
//Must unregister onPause()
@Override
public void onPause() {
super.onPause();
getActivity().unregisterReceiver(mMessageReceiver);
}
//This is the handler that will manager to process the broadcast intent
private BroadcastReceiver mMessageReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
// Extract data included in the Intent
String message = intent.getStringExtra("message");
//do other stuff here
connectToDatabase();
}
};
最佳答案
好的。因此,您的代码发生的情况是,您正在向 Receiver 发送广播,并强制再次调用 onHandleIntent
,结果调用 updateActivity 方法,该方法再次广播并无限循环。
在您的updateMyActivity
方法中,请更改:
Intent intent = new Intent("com.google.android.c2dm.intent.RECEIVE");
到
Intent intent = new Intent("myMessage");
这里的罪魁祸首是
com.google.android.c2dm.intent.RECEIVE
广播时调用 onHandleIntent。
此外,在 Activity 的onResume
方法中,请将TAG 更改为myMessage
:
getActivity().registerReceiver(mMessageReceiver, new IntentFilter("myMessage"))
