如何修复它，以便不执行重新启动应用程序过程。谢谢
使用以下代码更改语言
if (context != null) {
Resources res = context.getResources();
DisplayMetrics dm = res.getDisplayMetrics();
android.content.res.Configuration conf = res.getConfiguration();
conf.setLocale(new Locale(language));
res.updateConfiguration(conf, dm);
}
它不会立即反映，因此要解决此问题，只需打开它应该反映的默认或启动器活动。
