本文介紹了Android輕松實現多語言的方法示例，分享給大家，具體如下：

1.創建多語言包

2.首先在onCreate方法中調用此方法查看上一次保存的是什么語言

 public void setLanguage() {    //根據讀取到存放在sp里面的數據 進行設置    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.點擊某個按鈕彈出選擇框選擇語言包

  btn_qiehuan.setOnClickListener(new View.OnClickListener() {      @Override      public void onClick(View v) {        String[] strings = {"簡體中文", "English"};        //首次進入判斷是否是中文語言        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() {                  //點擊單選框某一項以后                  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();                    //重啟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();      }    });
