问题描述
大家.:) 我有一个多布局的应用程序，我试图在运行应用程序时更改语言.我发现此代码可以帮助我更改语言
everyone. :) I have App with a multi-layout and I'm trying to change the language while running the app. I find this code to help me change the language
using Android.Content;
using Android.OS;
using Java.Util;
namespace RuntimeAppLanguage
{
internal class LanguageManager
{
private const string MYLANGUAGE = "myLanguage";
private const string MYPREF = "myPreference";
public static Context LoadLanguage(Context context)
{
var loadedLanguage = GetLanguage(context, Locale.Default.Language);
return ChangeLanguage(context, loadedLanguage);
}
public static Context ChangeLanguage(Context context, string language)
{
SaveLanguage(context, language);
if (Build.VERSION.SdkInt >= BuildVersionCodes.N)
{
return ChangeForAPI24(context, language);
}
return ChangeForLegacy(context, language);
}
private static string GetLanguage(Context context, string Language)
{
var privatePreference = context.GetSharedPreferences(MYPREF, FileCreationMode.Private);
return privatePreference.GetString(MYLANGUAGE, Language);
}
private static void SaveLanguage(Context context, string language)
{
var privatePreference = context.GetSharedPreferences(MYPREF, FileCreationMode.Private);
var editor = privatePreference.Edit();
editor.PutString(MYLANGUAGE, language);
editor.Apply();
}
private static Context ChangeForAPI24(Context context, string language)
{
// for api >= 24
var locale = new Locale(language);
Locale.Default = locale;
var configuration = context.Resources.Configuration;
configuration.SetLocale(locale);
configuration.SetLayoutDirection(locale);
return context.CreateConfigurationContext(configuration);
}
private static Context ChangeForLegacy(Context context, string language)
{
var locale = new Locale(language);
Locale.Default = locale;
var resources = context.Resources;
var configuration = resources.Configuration;
configuration.Locale = locale;
resources.UpdateConfiguration(configuration, resources.DisplayMetrics);
return context;
}
}
}
我正试图让它在这个布局下工作，但我最终得到了循环:(
and I'm trying to make it work at this layout but I end up with loop :(
我想要做的是，当用户选中英语时，阿拉伯语开关转为取消选中等等.
what I'm trying to do is when the user checks English the Arabic switch turn to uncheck and so on.
<RelativeLayout

请帮帮我:(
推荐答案
我用中文"、英文"和泰国"写了一个简单的样例，是否满足你的需求:
i write a simple sample with "Chinese","English" and "Thailand",whether it meets your needs:
1.LanguageManager类，代码同上.
2.MainActivity，其中包括一个 TextView 和一个 Button；
2.MainActivity which includes a TextView and a Button;
3.在BaseActivity
public class BaseActivity: AppCompatActivity
{
protected override void AttachBaseContext(Context @base)
{
base.AttachBaseContext(LanguageManager.LoadLanguage(@base));
}
}
4.在SettingActivity里面可以设置语言，类似你的axml
4.in SettingActivity which could set the language,the axml similar to yours
public class SettingActivity : BaseActivity, CompoundButton.IOnCheckedChangeListener
{
private Switch swCh;
private Switch swEn;
private Switch swTh;
private Bundle s;
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
SetContentView(Resource.Layout.setting);
// Create your application here
initView();
}
private void initView()
{
Button back = FindViewById<Button>(Resource.Id.back);
back.Click += delegate { Finish(); };
swCh = FindViewById<Switch>(Resource.Id.switch1);
swEn = FindViewById<Switch>(Resource.Id.switch2);
swTh = FindViewById<Switch>(Resource.Id.switch3);
var s = GetSharedPreferences("myPreference", FileCreationMode.Private).GetString( "myLanguage", Locale.Default.Language);
switch (s)
{
case "ch":
swCh.Checked = true;
break;
case "en":
swEn.Checked = true;
break;
case "th":
swTh.Checked = true;
break;
}
swCh.SetOnCheckedChangeListener(this);
swEn.SetOnCheckedChangeListener(this);
swTh.SetOnCheckedChangeListener(this);
}
public void OnCheckedChanged(CompoundButton buttonView, bool isChecked)
{
if (isChecked)
{
switch (buttonView.Id)
{
case Resource.Id.switch1:
swEn.Checked = false;
swTh.Checked = false;
LanguageManager.ChangeLanguage(this, "ch");
break;
case Resource.Id.switch2:
swCh.Checked = false;
swTh.Checked = false;
LanguageManager.ChangeLanguage(this, "en");
break;
case Resource.Id.switch3:
swEn.Checked = false;
swCh.Checked = false;
LanguageManager.ChangeLanguage(this, "th");
break;
}
//restart application to change language
Intent intent = new Intent(this, typeof(MainActivity));
intent.SetFlags(ActivityFlags.ClearTask | ActivityFlags.NewTask);
StartActivity(intent);
}
}
}
5.create values-en, values-th 包括每种语言的strings
5.create values-en, values-th which include strings for each language
a.值/字符串
a.values/strings
<string name="change_language">改变语言</string>
<string name="setting">设置</string>
<string name="chinese">中文</string>
<string name="english">英语</string>
<string name="thailand">泰语</string>
b.values-en/strings
b.values-en/strings
<string name="change_language">change language</string>
<string name="setting">setting</string>
<string name="chinese">chinese</string>
<string name="english">english</string>
<string name="thailand">thailand</string>
c.values-th/strings
c.values-th/strings
<string name="change_language">เปลี่ยนภาษา</string>
<string name="setting">เปลี่ย</string>
<string name="chinese">ชาวจีน</string>
<string name="english">อังกฤษ</string>
<string name="thailand">ประเทศไทย</string>
ps:Text的所有内容都应该使用@string/***，并且每种语言在values/string中使用相同的名称>
ps: all the content of Text should use @string/*** and each language use the same name in the values/string
喜欢这个效果:
