Android之国际化(在程序内部强制转换语言)

首先看一下效果图：

        

项目结构图：

 

Android 3.0以下版本的做法：

import java.util.Locale;
import android.app.Activity;
import android.app.AlertDialog;
import android.content.Context;
import android.content.DialogInterface;
import android.content.Intent;
import android.content.SharedPreferences;
import android.content.SharedPreferences.Editor;
import android.content.res.Configuration;
import android.content.res.Resources;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemSelectedListener;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.Spinner;

public class HelloMyL10NActivity extends Activity {
    private SharedPreferences preferences;
    
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
//        if(savedInstanceState==null){
//            savedInstanceState = getIntent().getBundleExtra("Instance");
//            if(savedInstanceState!=null){
//                onRestoreInstanceState(savedInstanceState);
//            }
//        }
        preferences = getSharedPreferences("lang",Context.MODE_PRIVATE);
        String langString = preferences.getString("lang", "en");
        setLanguage(langString);
        setContentView(R.layout.main);
        
        Button b;
        (b = (Button)findViewById(R.id.flag_button)).setBackgroundDrawable(this.getResources().getDrawable(R.drawable.flag));
                        
        //语言选择
        final String lang[] = new String[]{"en","fr","de","ja"};
        String items[] = new String[]{"英文","法文", "德文", "日文"};
        Spinner spinner = (Spinner)findViewById(R.id.chooseLang);
        spinner.setAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item,items));
        if(preferences.getInt("lang",0) != 0){
            spinner.setSelection(savedInstanceState.getInt("position"), true);
        }
        spinner.setOnItemSelectedListener(new OnItemSelectedListener() {

            @Override
            public void onItemSelected(AdapterView<?> parent, View view,
                    int position, long id) {
                if(!(preferences.getString("lang", "en").equals(lang[position]))){
                    setLanguage(lang[position]);
                    Editor editor = preferences.edit();
                    editor.putString("lang", lang[position]).commit();
                    
                    Intent intent = new Intent(HelloMyL10NActivity.this,HelloMyL10NActivity.this.getClass());
                    startActivity(intent);
                    finish();
                }
                
            }

            @Override
            public void onNothingSelected(AdapterView<?> parent) {
                // TODO Auto-generated method stub
            }
        });
    }
    
    
    private void setLanguage(String langString){
        
         Resources resources = getResources(); 
         Configuration config = resources.getConfiguration(); 
         Locale locale = new Locale(langString);
         Locale.setDefault(locale);
         config.locale = locale; //简体中文 
         resources.updateConfiguration(config, null); 
    }

}  

这种方法来到Android 4.0就行不通，文字的效果还是有国际化但是图片就没有了国际化的效果。

推荐一个博客http://blog.csdn.net/a_colt/article/details/6193857  ，看一下它里面说的这个问题你有没有存在

“但同时发现了个问题

如果是用 button 的事件来触发

对于同一activity 中已生成的 目录按钮 不起作用，但对于触发前还没生成的对话框却起作用，是不是在触发后需要刷新下以生成的目录菜单呢？ ”

最后上传一个国际化转化的工具类，用的时候需要以下配置： /Files/lee0oo0/LanguageSettingUtil.rar

LanguageSettingUtil.init(getActivity());

languageSetting = LanguageSettingUtil.get();

//拿到当前系统语言设置

final String curSysLanguage = Locale.getDefault().getLanguage();

languageSetting.checkSysChanged(curSysLanguage); 

 

// 设置更换的语言 

languageSetting.saveLanguage("zh");

// 更新 

languageSetting.refreshLanguage();
