android程序怎样进行语言切换

 首先创建多语言资源，参考

在MainActivity的onCreate（）中添加如下代码

 public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

       String languageToLoad  = "zh";

        Locale locale = new Locale(languageToLoad);

        Locale.setDefault(locale);

        Configuration config = new Configuration();

        config.locale = locale;

        getBaseContext().getResources().updateConfiguration(config， null);

    }

AndroidManifest.xml中：

<application android:icon="@drawable/icon" android:label="@string/app_name">

        <activity android:name=".MainActivity"

                  android:label="@string/app_name"

                 android:configChanges="locale">

            <intent-filter>

                <action android:name="android.intent.action.MAIN" />

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

            </intent-filter>

        </activity>

    </application>

    <supports-screens

       android:smallScreens="true"

       android:normalScreens="true"

       android:largeScreens="true"

       android:anyDensity="true"/>

每一个Activity中都要加： android:configChanges="locale"。

加 <supports-screens>是为了解决如下问题：
