二：设置语言后要跳转的activity加入（这里拿VipLoginActivity登录作为重启activity）
public static void reStart(Context context) {
Intent intent = new Intent(context, VipLoginActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent);
}
二：所有activity基类里都加入（这里是关键，一定要保证所有activity都加入一下代码，如果有activity有没添加，一旦该activity处于栈里就会出现语言错乱混合）

//国际化
@Override
protected void attachBaseContext(Context newBase) {
super.attachBaseContext(LocalManageUtil.setLocal(newBase));
}
@Override
public Resources getResources() {
Resources res = super.getResources();
Configuration config = new Configuration();
config.setToDefaults();
res.updateConfiguration(config, res.getDisplayMetrics());
return res;
}
