GCMIntentService的额外意图不通过 [英] Intent Extras of GCMIntentService is not passed

问题描述

I codeD GCMIntentService 而是叫活动不能得到其他。

I coded GCMIntentService but called Activity cannot get the Extras.

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

    Intent resultIntent = new Intent(this, MainActivity.class).setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |
            Intent.FLAG_ACTIVITY_SINGLE_TOP);
        resultIntent.putExtra("PushType", "test"); // Put String Extra.

    PendingIntent resultPendingIntent = PendingIntent.getActivity(this, 0, resultIntent, PendingIntent.FLAG_UPDATE_CURRENT);
}

和名为 MainActivity 是如下codeD。

and called MainActivity is coded as below.

@Override
protected void onResume() {
    super.onResume();

    final Intent receivedIntent = getIntent();

    if (receivedIntent != null && receivedIntent.hasExtra("PushType")) {
            // Breakpoint at here. but no Extras are given.
        }       
    }
}

我在做断点 receivedIntent 和 mExtras 里面它显示为空。

此外，我称之为 MainActivity 清单是如下codeD。

Additionally, my called MainActivity manifest is coded as below.

        <activity
        android:name=".MainActivity"
        android:theme="@android:style/Theme.NoTitleBar"
        android:configChanges="keyboardHidden|orientation|screenSize"
        android:label="@string/app_name">
        <intent-filter>
            <category android:name="android.intent.category.DEFAULT"/>
        </intent-filter>
    </activity>

我改叫意图另一个活动并成功加载其他方案。
替代活动（其中包括成功额外）的表现是如下。

I changed called intent to another Activity and it successfully loads Extras. The manifest of substitute activity (which successfully contains Extras) was as below.

        <activity
        android:name=".NotificationActivity"
        android:parentActivityName=".MainActivity">
        <meta-data
            android:name="android.support.PARENT_ACTIVITY"
            android:value=".MainActivity"/>
    </activity>

我是怎么了？

推荐答案

看起来你需要重写onNewIntent（意向意图）方法和内部onNewIntent（）调用setIntent（意向）。然后onResume（）将搭载新的意图。见<一href=\"http://developer.android.com/reference/android/app/Activity.html#onNewIntent%28android.content.Intent%29\"相对=nofollow> onNewIntent（）了解详细信息。

It looks like you need to override onNewIntent(Intent intent) method and inside onNewIntent() call setIntent(intent). Then onResume() will pick up the new intent. See onNewIntent() for more detail.
