第二步：Application设置加载语言(适配7.0及以下)

class MyApplication : Application() {

override fun onCreate() {

super.onCreate()

//7.0以下加载此方法

if (Build.VERSION.SDK_INT < Build.VERSION_CODES.N) {

setLanguage()

}

}

override fun onConfigurationChanged(newConfig: Configuration) {

super.onConfigurationChanged(newConfig)

//7.0以下加载此方法

if (Build.VERSION.SDK_INT < Build.VERSION_CODES.N) {

setLanguage()

}

}

/**

* 设置加载语言

*/

private fun setLanguage() {

val localconfig = SPUtils.spUtils.get(applicationContext, MyParms.LANGUAGE,"") as String

val config = resources.getConfiguration()

val metrics = resources.getDisplayMetrics()

var mlocale: Locale? = null

if (null != localconfig && !"".equals(localconfig)) {

mlocale = Locale(localconfig);

} else {

mlocale = Locale.getDefault();

}

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {

config.setLocale(mlocale)

}else{

config.locale = mlocale

}

resources.updateConfiguration(config, metrics)

}

}

第三步：activity设置加载语言(适配8.0及以上)

open class BaseActivity : FragmentActivity() {

override fun attachBaseContext(newBase: Context?) {

super.attachBaseContext(newBase)

setLanguage()

}

/**

* 设置加载语言

*/

private fun setLanguage() {

val localconfig = SPUtils.spUtils.get(applicationContext, MyParms.LANGUAGE,"") as String

val config = resources.getConfiguration()

val metrics = resources.getDisplayMetrics()

var mlocale: Locale? = null

if (null != localconfig && !"".equals(localconfig)) {

mlocale = Locale(localconfig);

} else {

mlocale = Locale.getDefault();

}

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {

config.setLocale(mlocale)

}else{

config.locale = mlocale

}

resources.updateConfiguration(config, metrics)

}

}

第四步：切换语言

val config: Configuration = resources.configuration

val dm = resources.displayMetrics

when(chooseType){

1 ->{//中文简体

config.locale = Locale.SIMPLIFIED_CHINESE

}

2 ->{//english

config.locale = Locale.ENGLISH

}

}

resources.updateConfiguration(config, dm)

SPUtils.spUtils.put(this,MyParms.LANGUAGE,config.locale.getLanguage())

//这边不知道怎么回事儿，必须要阻塞几百毫秒才能切换成功

Thread.sleep(500)

//切换成功后必须要重启app，才能生效

restartApp(this, xxx::class.java)

WebView(this).destroy()

重启app代码

/**

* 重启app

*/

fun restartApp(activity: Activity, homeClass: Class?) {

val intent = Intent(activity, homeClass)

intent.flags = Intent.FLAG_ACTIVITY_NEW_TASK or Intent.FLAG_ACTIVITY_CLEAR_TASK

startActivity(intent)

Process.killProcess(Process.myPid())

System.exit(0)

}
