这个问题已经被问过 - 但没有令人满意的答案了！所以我再次尝试它。

我想给我的应用程序启动器图标（上显示的启动画面的一个！）不同，短标题。看来发射器采用其标签，从对主要活动的标签mainfest部分，如下：

 ＆LT;活动机器人：名称=MainActivity机器人：标签=@字符串/ app_short_name＆GT;
＆LT;意向滤光器＆gt;
    ＆lt;作用机器人：名称=android.intent.action.MAIN/＆GT;
    ＆LT;类机器人：名称=android.intent.category.LAUNCHER/＆GT;
＆所述; /意图滤光器＆gt;
 

我已经改变了原来的引用我的应用程序的名称@字符串/ APP_NAME到一个不同的，较短的字符串这里的资源。

但是 - 大的可是：这当然也改变了本次活动的默认的标题！而且我不希望这种情况发生，有足够的空间，长期应用程序名！使用的setTitle（INT）方法的onCreate 重新设定长的标题确实没有好或者，因为短域名会是可见的很短的时间的用户，但足够长以通知！

和 - 请不要回答我的提问指的是一个自定义标题栏......我不想去，只是因为一个愚蠢的字符串的标题，很长的路要走，！这是一个痛苦的画一个自定义标题栏所以影响不大！

有没有简单的方法就这样给发射一个不同的字符串来显示？ 谢谢您的回答！

编辑：还有一个原因，有一个自定义标题栏是一个痛苦的是，它不会像默认的标题栏，我会明确地做事情，使它看起来很像在每台设备上！这不可能是一个解决方案，如果，毕竟，我不希望有一个不同的外观！

解决方案找到了！

显然＆LT;意图过滤器>可以拥有一个标签属性。如果它是不存在的标签从父组件（或者活动或应用程序）继承。所以用这个，你可以设置为启动器图标的标签，同时还具有与它自己的标题活动。

http://developer.android.com/guide/topics/manifest/intent-filter-element.html

 ＆LT;活动
  机器人：名称=。ui.HomeActivity
  机器人：标签=@字符串/ title_home_activity
  机器人：图标=@可绘制/图标＆GT;
  ＆LT;意图过滤器的Andr​​oid版本：标签=@字符串/ APP_NAME＆GT;
    ＆lt;作用机器人：名称=android.intent.action.MAIN/＆GT;
    ＆LT;类机器人：名称=android.intent.category.LAUNCHER/＆GT;
  ＆所述; /意图滤光器＆gt;
＆LT; /活性GT;
 

侧注意：＆lt;意图过滤器>也可以有一个图标的属性，但   莫名其妙地它的没有的覆盖在指定的图标   活动。如果你打算使用本机，这可能对你很重要   动作条在SDK 11+，使用图标和标识的指定   活动。

新增信息：为活动的继承的标签，而不是应用程序

 ＆lt;应用
        机器人：allowBackup =真
        机器人：图标=@可绘制/ ic_launcher
        机器人：标签=@字符串/ APP_NAME
        机器人：主题=@风格/ AppTheme＆GT;

        ＆LT;活动
            机器人：名称=。StartActivity
            机器人：标签=@字符串/ app_long_name＆GT;
            ＆LT;意向滤光器＆gt;
                ＆lt;作用机器人：名称=android.intent.action.MAIN/＆GT;
                ＆LT;类机器人：名称=android.intent.category.LAUNCHER/＆GT;
            ＆所述; /意图滤光器＆gt;
        ＆LT; /活性GT;
 

在这种情况下，app_long_name将与发射器图标显示出来，如果​​我们不把标签内，如上所述。

This question has been asked before - but with no satisfying answer at all! So I'm trying it again.

I want to give my application launcher icon (the one that is displayed on the startscreen!) a different, shorter caption. It seems the launcher takes its label from the mainfest section about the main activity's label, as here:

<activity android:name="MainActivity" android:label="@string/app_short_name">
<intent-filter>
    <action android:name="android.intent.action.MAIN" />
    <category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

I already changed the original reference to my app's name @string/app_name to a different, shorter string resource here.

BUT - big BUT: this also of course changes this activity's default title! And I did not want that to happen, there's enough space for a long application name! Setting the long title again in onCreate using the setTitle(int) method does no good either, because the short name will be visible to the user for a short time, but long enough to notice!

And - please don't answer my question by refering to a custom titlebar... I do not want to go that long way, just because of a stupid string title! It's a pain to draw a custom title bar for so little effect!

Is there no easy way to just give the launcher a different string to display? Thanks for your answers!

Edit: One more reason why having a custom titlebar is a pain is that it will not look like the default titlebar, I would have to explicitly do things to make it look alike on each device! And that can't be a solution if, after all, I don't want a different appearance!

Solution found!

Apparently <intent-filter> can have a label attribute. If it's absent the label is inherited from the parent component (either Activity or Application). So using this, you can set a label for the launcher icon, while still having the Activity with it's own title.

http://developer.android.com/guide/topics/manifest/intent-filter-element.html

<activity
  android:name=".ui.HomeActivity"
  android:label="@string/title_home_activity"
  android:icon="@drawable/icon">
  <intent-filter android:label="@string/app_name">
    <action android:name="android.intent.action.MAIN" />
    <category android:name="android.intent.category.LAUNCHER" />
  </intent-filter>
</activity>

Side Note: <intent-filter> can also have an icon attribute, but inexplicably it does not override the icon specified in the Activity. This may be important to you if you plan to use the native ActionBar in SDK 11+, which uses Icon and Logo specified on the Activity.

Added Info: The label is being inherited from Activity and not the Application.

 <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"       
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >

        <activity
            android:name=".StartActivity"
            android:label="@string/app_long_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

In this case, app_long_name will be displayed with launcher icon, if we do not put label inside as mentioned above.
