Android 更改区域设置后刷新NavigationView菜单

我正在以编程方式从片段更改区域设置，一切正常。有一个例外，NavigationView菜单，语言没有改变。如何在不重新创建所有活动的情况下刷新它

主活动代码

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    context = this;


    NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
    navigationView.setNavigationItemSelectedListener(this);
    navigationView.setEnabled(false);

    DrawerLayout mDrawer = (DrawerLayout) findViewById(R.id.drawer_layout);
    mDrawer.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);
}

R.layout.activity\u main

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent">

    <android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        xmlns:tools="http://schemas.android.com/tools" android:id="@+id/drawer_layout"
        android:layout_width="match_parent" android:layout_height="match_parent"
        android:fitsSystemWindows="true" tools:openDrawer="start">

            <include layout="@layout/app_bar_main" android:layout_width="match_parent"
                android:layout_height="match_parent" />

        <android.support.design.widget.NavigationView android:id="@+id/nav_view"
            android:layout_width="wrap_content" android:layout_height="match_parent"
            android:layout_gravity="start" android:fitsSystemWindows="true"
            app:headerLayout="@layout/nav_header_main" app:menu="@menu/activity_main_drawer"/>

    </android.support.v4.widget.DrawerLayout>

Thanx

您可以尝试下面的代码。我还没有测试过，但我希望它能工作

for (int i = 0, count = navigationView.getChildCount(); i < count; i++) {
    final View child = navigationView.getChildAt(i);
    if (child != null && child instanceof ListView) {
        final ListView menuView = (ListView) child;
        final HeaderViewListAdapter adapter = (HeaderViewListAdapter) menuView.getAdapter();
        final BaseAdapter wrapped = (BaseAdapter) adapter.getWrappedAdapter();
        wrapped.notifyDataSetChanged();
    }
}

for（int i=0，count=navigationView.getChildCount（）；i

我已经决定了这个问题

private void refreshNavigationView(){

    getActivity().setContentView(R.layout.activity_main);
    NavigationView navigationView = (NavigationView)  getActivity().findViewById(R.id.nav_view);

}

这就足够在更改区域设置后刷新NavigationView了

但我失去了onNavigationItemSelected

因此，在main活动中

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);

    // Checks the locale has changed
    if (!currentLocale.equals(newConfig.locale)) {
        currentLocale = newConfig.locale;

        this.setContentView(R.layout.activity_main);
        NavigationView navigationView = (NavigationView)  this.findViewById(R.id.nav_view);
        navigationView.setNavigationItemSelectedListener(MainActivity.this);
    }
} 

断片

getActivity().onConfigurationChanged(getActivity().getResources().getConfiguration());

如何填充导航抽屉？列表或简单视图项。菜单布局包装中的项。getCount（）返回6。如果为真，我在菜单中有6项，但notifyDataSetChanged（）未刷新菜单或不了解新区域我已完成以下操作：（navigationView.getMenu（））.addSubMenu（“xxx”）；它添加了新项，但没有更改localeAt您将其称为OnAttachWindow的点是什么？或者在更改区域设置之后？我将静态方法放在MainActivity中，并在更改区域设置之后从fragmrnt调用它ft.detach（this.attach）（this.commit（）；MainActivity.refreshNavigationView（）；我认为有必要刷新setContentView（R.layout.activity_main）；对于从resourcesIdeally重新读取数据和新id，不应为。因为抽屉总是在那个里，它只是因为左边的重力而被隐藏了起来。您可以尝试在回调onDarwerOpen（）中刷新NavigationView

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);

    // Checks the locale has changed
    if (!currentLocale.equals(newConfig.locale)) {
        currentLocale = newConfig.locale;

        this.setContentView(R.layout.activity_main);
        NavigationView navigationView = (NavigationView)  this.findViewById(R.id.nav_view);
        navigationView.setNavigationItemSelectedListener(MainActivity.this);
    }
} 

getActivity().onConfigurationChanged(getActivity().getResources().getConfiguration());
