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();
      }
    });
