Question

我有一个 loginActivity 和 MainActivity，其中包含多个片段，其中之一称为 NotificationFragment。

要求：假设用户已经登录并且当前在 Home Fragment（在 Main Activity 内）并且应用程序在后台。现在他们收到推送通知，用户应该被重定向到通知片段（在 Main Activity 上）。

截至目前，登录 Activity 正在从通知中接收意向数据。登录 Activity 是我们目前的发布 activity。

问题：Login Activity（在返回堆栈上）应如何通知 Main Activity 将用户从 Home Fragment 重定向到 Notification Fragment？

清单看起来像这样：

<activity
        android:name="com.X.LoginActivity"
        android:configChanges="orientation"
        android:icon="@mipmap/ic_launcher"
        android:screenOrientation="portrait"
        android:windowSoftInputMode="adjustPan">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
        <intent-filter>

            <!-- Sets the intent action to view the activity -->
            <action android:name="android.intent.action.VIEW" />
            <!-- Allows the link to be opened from a web browser -->
            <category android:name="android.intent.category.BROWSABLE" />
            <!-- Allows the deep link to be used without specifying the app name -->
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>

    </activity>
    <activity
        android:name="com.X.MainActivity"
        android:configChanges="orientation"
        android:launchMode="singleTop"
        android:screenOrientation="portrait"
        android:theme="@style/AppTheme.NoActionBar"
        android:windowSoftInputMode="adjustPan" />

试试这个

 private void sendMyNotification(String title,String message) {

    //On click of notification it redirect to this Activity
    Intent intent = new Intent(this, MainActivity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_ONE_SHOT);

    Uri soundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    Bitmap icon = BitmapFactory.decodeResource(getResources(),
            R.mipmap.ic_appicon);
    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this,"Default")
            .setSmallIcon(R.drawable.ic_noti_new)
            .setLargeIcon(icon)
            .setContentTitle(title)
            .setContentText(message)
            .setAutoCancel(true)
            .setSound(soundUri)
            .setContentIntent(pendingIntent);

    NotificationManager notificationManager =
            (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    notificationManager.notify(0, notificationBuilder.build());
}

它将触发主activity。

添加

android:launchMode="singleTask" in your mainactivity to avoid running mutiple instance of MainActivity.

 <activity
        android:name=".MainActivity"
        android:launchMode="singleTask" />
