如何强制Android应用程序重新加载相应的语言更改活动标题？ [英] How to force Android application to reload the activity title corresponding to the language change?

问题描述

在应用程序的语言已更改怎么可能迫使Android应用程序重新加载活动的标题？为了您的信息，应用程序重新加载，只有当设备旋转的称号。然而，活动的内容重新装入相应的语言内容没有问题，但活动标题！

How could force android application to reload activity title when the language of the application has been changed? For your information, the application reloads the title only when the device is rotated. Yet, the content of the activity is reload with the appropriate language content with no problem, but the activity title!

在AndroidManifest.xml文件，安卓。configChanges =语言环境已经被加入，但没有成功。

In AndroidManifest.xml file, android:configChanges="locale" has been added with no success.

<activity
    android:name=".layout.MainActivity"
    android:configChanges="locale"
    android:label="@string/app_name" />

甚至压倒一切的onConfigurationChanged事件不能正常工作，

Even overriding onConfigurationChanged event does not work,

@Override
public void onConfigurationChanged(Configuration newConfig) {
    // refresh your views here
    super.onConfigurationChanged(newConfig);

    this.setTitle(getResources().getString(R.string.app_name));
}

感谢您，

同样的问题，通过强制标签的ActionBar在重装解决活动的onCreate 方法：

Same problem, solved by forcing ActionBar label reload in Activity onCreate method:

    PackageManager pm = getPackageManager();
        try {
            ActivityInfo ai = pm.getActivityInfo(this.getComponentName(), PackageManager.GET_ACTIVITIES|PackageManager.GET_META_DATA);
            if (ai.labelRes != 0) {
                getSupportActionBar().setTitle(ai.labelRes);
            }
        } catch (PackageManager.NameNotFoundException e) {
            e.stacktrace();
        }
