blocks|key|958049|text|对于第一个问题，您应该知道，在启动应用程序上没有标签的情况下，名称来自应用程序标记的android:label属性中设置的默认标签：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|958050|<application+android:name="ApiDemosApplication"
+++android:label="@string/activity_sample_code"
+++android:icon="@drawable/app_sample_code">|code-block|syntax|javascript|958051|如果Activity有标签，则将使用该标签。|958052|对于第二个问题，在清单中，您的所有活动很可能都指定了一个带有android.intent.category.LAUNCHER操作的意图过滤器。例如：|958053|<activity+android:name="ApiDemos">
+++++<intent-filter>
+++++++++<action+android:name="android.intent.action.MAIN"+/>
+++++++++<category+android:name="android.intent.category.DEFAULT"+/>
+++++++++<category+android:name="android.intent.category.LAUNCHER"+/>
+++++</intent-filter>
</activity>|958054|如果您在所有活动上都有这样的意图过滤器标签，那么除了要在启动时启动的Activity之外，您应该删除所有其他活动上的意图过滤器标签。如果此Activity有标签，则该标签将与启动器图标一起显示。|958055|截至2019/01/03在27%2B接口上，LAUNCHER类别的第一个活动似乎将启动，其标签将与应用程序图标关联，因此可能没有严格的必要删除所有多余的意图过滤器，但我无论如何都会这样做，因为这可能会导致混淆。|958056|entityMap^0|16|D|0|0|2|8|0|0|0|Y|8|1X|8|0|K|8|0^^$0|@$1|2|3|4|5|6|7|W|8|@$9|X|A|Y|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|Z|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|10|8|@$9|11|A|12|B|C]]|D|@]|E|$]]|$1|M|3|N|5|6|7|13|8|@]|D|@]|E|$]]|$1|O|3|P|5|H|7|14|8|@]|D|@]|E|$I|J]]|$1|Q|3|R|5|6|7|15|8|@$9|16|A|17|B|C]|$9|18|A|19|B|C]]|D|@]|E|$]]|$1|S|3|T|5|6|7|1A|8|@$9|1B|A|1C|B|C]]|D|@]|E|$]]|$1|U|3|-4|5|6|7|1D|8|@]|D|@]|E|$]]]|V|$]]

For the first issue, you should be aware that in absence of a label on the launching <code>Activity</code> the name comes from the default label set in the <code>android:label</code> attribute on the application tag:

<pre><code>&lt;application android:name="ApiDemosApplication"
 android:label="@string/activity_sample_code"
 android:icon="@drawable/app_sample_code"&gt;
</code></pre>

If the <code>Activity</code> has a label, that label will be used instead.

For the second issue, in the manifest, it is likely that all your activities specify an intent filter with an action of android.intent.category.LAUNCHER. For example:

<pre><code>&lt;activity android:name="ApiDemos"&gt;
 &lt;intent-filter&gt;
 &lt;action android:name="android.intent.action.MAIN" /&gt;
 &lt;category android:name="android.intent.category.DEFAULT" /&gt;
 &lt;category android:name="android.intent.category.LAUNCHER" /&gt;
 &lt;/intent-filter&gt;
&lt;/activity&gt;
</code></pre>

If you have such intent-filter tags on all activities, you should take out the intent filter tags on all but the <code>Activity</code> that you want to launch at startup. If this <code>Activity</code> has a label, it is the label that will be shown along with the launcher icon. 

As of 2019/01/03 on API 27+, it appears that the first activity with the <code>LAUNCHER</code> category will be launched and its label will be associated with the app icon, so it may not be strictly necessary to remove all the redundant intent filters, but I'd do it anyway because it can lead to confusion.

blocks|key|958139|text|当您通过Eclipse创建活动时，活动中的android:label属性会在AndroidManifest.xml中自动设置为"@string/+your+_+Activity+_name“。添加意图过滤器为此活动提供启动器，您的启动器将获得与您的活动相同的标签android:label。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|958140|如果你想用你的应用程序名来标记启动器，你应该将活动android:label改为类似于"@string/app_+name“的内容。|958141|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

When you create an Activity via Eclipse, the property android:label inside your activity is automatically set to "@string/your_activity_name" in the AndroidManifest.xml. Adding the intent filter to provide a launcher for this activity, your launcher gets the same label as your Activities android:label.

If you want to label the launcher with your application name, you should change the Activities android:label to something like "@string/app_name".

blocks|key|742314|text|要使应用程序名称(显示在应用程序图标下的名称)和当您点击应用程序图标时启动的活动具有不同的名称，一种方法是在活动的onCreate()方法中显式设置不同的字符串，如下所示：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|742315|@Override
public+void+onCreate(Bundle+savedInstanceState)+{
++super.onCreate(savedInstanceState);

++//+Do+your+thing
++//+...+bla+bla+bla

++getActionBar().setTitle(R.string.activity_title);
}|code-block|syntax|javascript|742316|希望这能有所帮助！|742317|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

One way to have a different application name (the name that appears under the app icon) and a different name for the activity that is being launched when you tap on the app icon is to explicitly set a different string in the activity's onCreate() method, like this:

<pre><code>@Override
public void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);

 // Do your thing
 // ... bla bla bla

 getActionBar().setTitle(R.string.activity_title);
}
</code></pre>

Hope this helps!

As if you want to place a image view in the place of toolbar title. You have to update the label of particular activity in the android manifest as <code>android:label="";</code> by doing this your activity name won't gets displayed in the toolbar after the image view and please use the following code for setting image view along with navigation icon and no toolbar title.

<pre><code>try {
 Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
 setSupportActionBar(toolbar);
 toolbar.setTitle("");
 if (getSupportActionBar() != null)
 getSupportActionBar().setIcon(R.drawable.header_image_wt);
} catch (Exception e) {
 e.getMessage();
}
</code></pre>

I have reviewed the manifest for application, and under apps launcher it displays as Activity Name rather than its app name? Why is this. I have another application where when I install it, there are 5 entries one for each activity in the application when there should be just one name, that of the app? So when I go to launch it has 5 identically named apps in the launch list. These are named after the app but there is one for each activity. What could be the reason for this?

Android Application Name Appears as Activity Name

Android

Eclipse

我已经检查了应用程序的清单，在应用程序启动程序下，它显示为活动名称而不是其应用程序名称？为什么会这样。我有另一个应用程序，当我安装它时，有5个条目，每个条目对应于应用程序中的每个活动，而实际上应该只有一个名称，应用程序的名称？所以当我启动时，启动列表中有5个同名的应用程序。这些都是以应用程序命名的，但每个活动都有一个。...
