Try setTitle by itself, like this:

单独尝试 setTitle，如下所示：

setTitle("Hello StackOverflow");

Just an FYI, you can optionally do it from the XML.

仅供参考，您可以选择从 XML 执行此操作。

In the AndroidManifest.xml, you can set it with

在 AndroidManifest.xml 中，你可以设置它

android:label="My Activity Title"

Or

或者

android:label="@string/my_activity_label"

Example:

例子：

    <activity
        android:name=".Splash"
        android:label="@string/splash_activity_title" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

If you want it one time & let system handle the rest (not dynamic) then do like this in your manifest file:

如果你想要一次并让系统处理其余的（不是动态的），那么在你的清单文件中这样做：

<application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name_full" > //This is my custom title name on activity. <- The question is about this one.
            <intent-filter android:label="@string/app_launcher_name" > //This is my custom Icon title name (launcher name that you see in android apps/homescreen)
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

setTitle(getResources().getText(R.string.MyTitle));

回答by moberme

This worked for me.

这对我有用。

public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.fragment, container, false);
    getActivity().setTitle("My Title");
//...
}

There's a faster way, just use

有一个更快的方法，只需使用

YourActivity.setTitle("New Title");

You can also find it inside the onCreate()with this, for example:

您还可以在onCreate() 中找到它，例如：

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        this.setTitle("My Title");
    }

By the way, what you simply cannot do is call setTitle() in a static way without passing any Activity object.

顺便说一句，您根本无法做的是在不传递任何 Activity 对象的情况下以静态方式调用 setTitle() 。

If you have multiple activities, you can set it like this in AndroidManifest.xml

如果你有多个activity，可以在AndroidManifest.xml中这样设置

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    <activity android:name=".MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name=".NumbersActivity"
        android:label="@string/category_numbers"
        android:theme="@style/category_numbers" />
    <activity
        android:name=".FamilyActivity"
        android:label="@string/category_family"
        android:theme="@style/category_family" />
    <activity
        android:name=".ColorsActivity"
        android:label="@string/category_colors"
        android:theme="@style/category_colors" />
    <activity
        android:name=".PhrasesActivity"
        android:label="@string/category_phrases"
        android:theme="@style/category_phrases" />
    <activity
        android:name=".ExperimentActivity"
        android:label="@string/category_experiment"
        android:theme="@style/category_experiment" />
</application>
