不想废话,直接上干货
@Override
protected void attachBaseContext(Context newBase) {
Locale newLocale;
if (SPUtil.getBoolean(newBase,"isEN")) {
//设置英文
newLocale = Locale.ENGLISH;
} else {
//设置中文
newLocale = Locale.SIMPLIFIED_CHINESE;
}
Context context = MyContextWrapper.wrap(newBase, newLocale);
super.attachBaseContext(context);
}
是的,直接在你继承的BaseActivity里面重载(@Override)attachBaseContext方法即可。
里面有一个自定义的MyContextWrapper:
import android.content.Context;
import android.content.ContextWrapper;
import android.content.res.Configuration;
import android.content.res.Resources;
import android.os.Build;
import android.os.LocaleList;
import java.util.Locale;
public class MyContextWrapper extends ContextWrapper {
public MyContextWrapper(Context base) {
super(base);
}
public static ContextWrapper wrap(Context context, Locale newLocale) {
Resources res = context.getResources();
Configuration configuration = res.getConfiguration();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
configuration.setLocale(newLocale);
LocaleList localeList = new LocaleList(newLocale);
LocaleList.setDefault(localeList);
configuration.setLocales(localeList);
context = context.createConfigurationContext(configuration);
} else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
configuration.setLocale(newLocale);
context = context.createConfigurationContext(configuration);
}
return new ContextWrapper(context);
}
}
关于SPUtil,就是一个简单的SharedPreferences内容存取类:
import android.content.Context;
import android.content.SharedPreferences;
public class SPUtil {
public static void put(Context context, String key, Object value) {
SharedPreferences sp = context.getSharedPreferences("config", Context.MODE_PRIVATE);
SharedPreferences.Editor edit = sp.edit();
if (value instanceof String) {
edit.putString(key, (String) value);
} else if (value instanceof Integer) {
//JDK1.7之后可以把引用数据类型转为基本数据类型
edit.putInt(key, (int) value);
} else if (value instanceof Boolean) {
edit.putBoolean(key, (boolean) value);
}
edit.apply();
}
public static String getString(Context context, String key) {
SharedPreferences sp = context.getSharedPreferences("config", Context.MODE_PRIVATE);
return sp.getString(key, "");
}
public static int getInt(Context context, String key) {
SharedPreferences sp = context.getSharedPreferences("config", Context.MODE_PRIVATE);
return sp.getInt(key, 0);
}
public static boolean getBoolean(Context context, String key) {
SharedPreferences sp = context.getSharedPreferences("config", Context.MODE_PRIVATE);
return sp.getBoolean(key, false);
}
public static void clearData(Context context){
SharedPreferences sp = context.getSharedPreferences("config", Context.MODE_PRIVATE);
sp.edit().clear().apply();
}
}
代码到这里也就结束了,下面是添加国际化语言的简单步骤:
切记修改语言之后一定要重新加载页面,不然不会立即生效
SPUtil.put(SettingActivity.this,"isEN",isChecked);
recreate();
