This article mainly introduces Android how to achieve Chinese and English language switching, the article introduces in great detail, has a certain reference value, interested friends must read it!

Code

@ Override protected void attachBaseContext (Context newBase) {Locale newLocale; if (SPUtil.getBoolean (newBase, "isEN")) {/ / set English newLocale = Locale.ENGLISH;} else {/ / set Chinese newLocale = Locale.SIMPLIFIED_CHINESE;} Context context = MyContextWrapper.wrap (newBase, newLocale); super.attachBaseContext (context);}

Yes, just overload (@ Override) the attachBaseContext method directly in the BaseActivity you inherited.

There is a custom 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);}}

About SPUtil, it is a simple SharedPreferences content access class:

Import android.content.Context;import android.content.SharedPreferences; public class SPUtil {/ * omnipotent put method (can store values of type String/int/boolean) * @ param context * @ param key * @ param value * / 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 can convert the reference data type to the basic data type edit.putInt (key, (int) value) } else if (value instanceof Boolean) {edit.putBoolean (key, (boolean) value);} edit.apply ();} / * get String * @ param context * @ param key * @ return * / public static String getString (Context context, String key) {SharedPreferences sp = context.getSharedPreferences ("config", Context.MODE_PRIVATE) Return sp.getString (key, ");} / * get int * @ param context * @ param key * @ return * / public static int getInt (Context context, String key) {SharedPreferences sp = context.getSharedPreferences (" config ", Context.MODE_PRIVATE); return sp.getInt (key, 0) } / * get Boolean * @ param context * @ param key * @ return * / public static boolean getBoolean (Context context, String key) {SharedPreferences sp = context.getSharedPreferences ("config", Context.MODE_PRIVATE); return sp.getBoolean (key, false) } / * * clear preferences * / public static void clearData (Context context) {SharedPreferences sp = context.getSharedPreferences ("config", Context.MODE_PRIVATE); sp.edit (). Clear (). Apply ();}}

This is the end of the code, and here are the simple steps to add an internationalized language:

Remember to reload the page after changing the language, otherwise it will not take effect immediately

SPUtil.put (SettingActivity.this, "isEN", isChecked); recreate (); these are all the contents of the article "how to switch between Chinese and English in Android". Thank you for reading!
