Android轻松实现多语言的方法示例

本文介绍了Android轻松实现多语言的方法示例，分享给大家，具体如下：

1.创建多语言包

2.首先在onCreate方法中调用此方法查看上一次保存的是什么语言

 public void setLanguage() {
    //根据读取到存放在sp里面的数据 进行设置
    Configuration configuration = getResources().getConfiguration();

    SharedPreferences sharedPreferences = getSharedPreferences("key", MODE_PRIVATE);
    int language = sharedPreferences.getInt("language", 0);

    switch (language) {
      case 0:
 configuration.setLocale(Locale.CHINESE);
 break;
      case 1:
 configuration.setLocale(Locale.ENGLISH);
 break;
    }
    getResources().updateConfiguration(configuration, getResources().getDisplayMetrics());
  }

3.点击某个按钮弹出选择框选择语言包

  btn_qiehuan.setonClickListener(new View.onClickListener() {
      @Override
      public void onClick(View v) {
 String[] strings = {"简体中文", "English"};
 //首次进入判断是否是中文语言
 int selected = getSharedPreferences("language", Context.MODE_PRIVATE).getInt("language", -1);
 if (selected == -1) {
   String defaultLanguage = Locale.getDefault().toString();
   if (defaultLanguage.equals(Locale.CHINESE.toString()) || defaultLanguage.equals(Locale.SIMPLIFIED_CHINESE.toString())
|| defaultLanguage.equals(Locale.TRADITIONAL_CHINESE.toString())) {
     selected = 0;
   } else {
     selected = 1;
   }
 }
 new alertDialog.Builder(MainActivity.this)
     .setSingleChoiceItems(strings, selected,
  new DialogInterface.onClickListener() {
    //点击单选框某一项以后
    public void onClick(DialogInterface dialogInterface, int i) {
      SharedPreferences preferences = getSharedPreferences("language", Context.MODE_PRIVATE);
      SharedPreferences.Editor editor = preferences.edit();
      editor.putInt("language", i);
      editor.commit();
      dialogInterface.dismiss();
      //重启activity
      finish();
      Intent intent = new Intent(MainActivity.this, MainActivity.class);
      intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
      startActivity(intent);
    }
  })
     .create()
     .show();
      }
    });
