由于從網(wǎng)上搜了很多文字化國家化適配的文章，感覺寫的都不是很全面而且在8.0上測試總是有問題文黎，所以經(jīng)過一番研究就把實現(xiàn)的方法整理出來惹苗，分享一下，本文主要是講代碼實現(xiàn)耸峭。（方便自己以后之際copy來用）
多語言文字切換實現(xiàn)
1.定義一個工具類桩蓉，內(nèi)容如下：
'''
public class LocaleManager {
public static final String LANGUAGE_ENGLISH = "en";
public static final String LANGUAGE_CHINESE = "zh";
private static final String LANGUAGE_KEY = "language_key";
public static Context setLocale(Context c) {
return updateResources(c, getLanguage(c));
}
//根據(jù)手機版本號進行設(shè)置語言環(huán)境
public static Context setNewLocale(Context c, String language) {
persistLanguage(c, language);
return updateResources(c, language);
}
//SharedPreferences獲取語言環(huán)境
public static String getLanguage(Context c) {
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(c);
return prefs.getString(LANGUAGE_KEY, LANGUAGE_ENGLISH);
}
@SuppressLint("ApplySharedPref")
private static void persistLanguage(Context c, String language) {
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(c);
// use commit() instead of apply(), because sometimes we kill the application process immediately
// which will prevent apply() to finish
prefs.edit().putString(LANGUAGE_KEY, language).commit();
}
private static Context updateResources(Context context, String language) {
Locale locale = new Locale(language);
Locale.setDefault(locale);
Resources res = context.getResources();
Configuration config = new Configuration(res.getConfiguration());
//做版本兼容性判斷
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
config.setLocale(locale);
context = context.createConfigurationContext(config);
} else {
config.locale = locale;
//點進去看方法詳情
res.updateConfiguration(config, res.getDisplayMetrics());
}
return context;
}
public static Locale getLocale(Resources res) {
Configuration config = res.getConfiguration();
return Build.VERSION.SDK_INT >= 24 ? config.getLocales().get(0) : config.locale;
}
}
'''
主要解決：updateConfiguration 方法過期的問題，但是這樣依舊很難再APP中把所有文字修改劳闹，因為Android26等高版本需要在Acivity中做如下操作：
BaseActivity
'''
public abstract class BaseActivity extends AppCompatActivity {
private static final String TAG = "BaseActivity";
@Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(LocaleManager.setLocale(base));
Log.d(TAG, "attachBaseContext");
}
}
'''
同時在Application中做如下設(shè)置：
'''
public class App extends Application {
private final String TAG = "App";
@Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(LocaleManager.setLocale(base));
Log.d(TAG, "attachBaseContext");
}
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
LocaleManager.setLocale(this);
Log.d(TAG, "onConfigurationChanged: " + newConfig.locale.getLanguage());
}
}
'''
補充：
'''
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.tvChinese:
LocaleManager.setNewLocale(this, LocaleManager.LANGUAGE_CHINESE);
break;
case R.id.tvEnglish:
LocaleManager.setNewLocale(this, LocaleManager.LANGUAGE_ENGLISH);
break;
}
Intent i = new Intent(this, MainActivity.class);
startActivity(i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK));
finish();
}
'''
經(jīng)過測試就可以正常在app中切換語言了具體細(xì)節(jié)在下一篇博客中做詳細(xì)講解院究。
