我正在构建一个应用程序，用户可以在应用程序启动时选择想要设置的语言。弹出窗口将显示“选择您的语言”，其中一个用于阿拉伯语，另一个用于英语。从Alert for Android设置语言（XAMARIN Studio）
的问题是，当我改变了语言环境和执行这条线
SetContentView (Resource.Layout.Main);
的应用打破了。没有错误或任何异常，但所有控件都停止捕获事件。我尝试使用this和this.Class声明一个Intent，当我调用StartActivity时，它就像重新启动整个应用程序一样，然后弹出窗口再次选择语言。我是新来的Android开发为我花了我近两年来在SAP ABAP工作，所以我可能会问一个愚蠢的问题：d
这里是我的代码
using System;
using Android.App;
using Android.Content;
using Android.Runtime;
using Android.Views;
using Android.Widget;
using Android.OS;
namespace Khums
{
[Activity (Label = "Khums", MainLauncher = true, Icon = "@drawable/icon")]
public class MainActivity : Activity
{
protected override void OnCreate (Bundle bundle)
{
base.OnCreate (bundle);
// Set our view from the "main" layout resource
int r = Resource.Layout.Main;
SetContentView (Resource.Layout.Main);
var languageIso = "ar-SA";
AlertDialog.Builder alert = new AlertDialog.Builder (this);
//alert.SetTitle ("Selected Language");
AlertDialog alertDiaog = alert.Create();
alertDiaog.SetTitle ("Select Language:");
alertDiaog.SetButton ("العربية", (s, EventArgs) => {
languageIso = "ar-SA";
var locale = new Java.Util.Locale(languageIso);
Java.Util.Locale.Default = locale;
var config = new Android.Content.Res.Configuration{Locale = locale };
BaseContext.Resources.UpdateConfiguration(config, BaseContext.Resources.DisplayMetrics);
//base.SetContentView(r);
//Intent intent = new Intent(this, this.Class);
//StartActivity(intent);
SetContentView (Resource.Layout.Main);
});
alertDiaog.SetButton2 ("English", (s, EventArgs) => {
languageIso = "en-US";
var locale = new Java.Util.Locale(languageIso);
Java.Util.Locale.Default = locale;
var config = new Android.Content.Res.Configuration{Locale = locale };
BaseContext.Resources.UpdateConfiguration(config, BaseContext.Resources.DisplayMetrics);
SetContentView (Resource.Layout.Main);
});
alertDiaog.Show();
Button button = FindViewById<Button> (Resource.Id.myButton);
RadioButton rb_FirstTime = FindViewById<RadioButton> (Resource.Id.radioButton1);
RadioButton rb_Regular = FindViewById<RadioButton> (Resource.Id.radioButton2);
EditText ti_lyearBalance = FindViewById<EditText> (Resource.Id.ti_lastBalance);
EditText ti_Balance = FindViewById<EditText> (Resource.Id.ti_Balance);
EditText ti_Clothes = FindViewById<EditText> (Resource.Id.ti_Clothes);
EditText ti_Food = FindViewById<EditText> (Resource.Id.ti_Food);
EditText ti_Perfumes = FindViewById<EditText> (Resource.Id.ti_Perfumes);
EditText ti_Subscriptions = FindViewById<EditText> (Resource.Id.ti_Subscriptions);
EditText ti_Others = FindViewById<EditText> (Resource.Id.ti_Others);
TextView lbl_lyearBalance = FindViewById<TextView> (Resource.Id.lbl_lastBalance);
rb_FirstTime.Click += RadioButtonHandler;
rb_Regular.Click += RadioButtonHandler;
button.Click += MyButtoHandler;
}
private void RadioButtonHandler(object sender, EventArgs e)
{
}
private void MyButtoHandler(object sender, EventArgs e)
{
}
private double calculateKhumus (double[] amounts, Boolean isRegular)
{
}
private void LangSwitchHndler(Object sender, EventArgs e)
{
}
}
}
可以请你告诉我，我什么在这里做错了。我试图使用togglebutton而不是alert和标准按钮，但最终出现同样的问题。谢谢。
