如何使用共享首选项存储3d字符串数组

String[][][] array3D = {
    {{"A1", "A2", "A3"}, {"B1", "B2", "B3"}, {"C1", "C2", "C3"}},
    {{"D1", "D2", "D3"}, {"E1", "E2", "E3"}, {"F1", "F2", "F3"}},
    {{"G1", "G2", "G3"}, {"H1", "H2", "H3"}, {"I1", "I2", "I3"}}
};

// 获取SharedPreferences对象
SharedPreferences sharedPreferences = getSharedPreferences("my_preferences", Context.MODE_PRIVATE);

// 创建一个编辑器
SharedPreferences.Editor editor = sharedPreferences.edit();

// 将数组转换为字符串
String arrayString = Arrays.deepToString(array3D);

// 将字符串存储到共享首选项中
editor.putString("array_key", arrayString);
editor.apply();

// 获取SharedPreferences对象
SharedPreferences sharedPreferences = getSharedPreferences("my_preferences", Context.MODE_PRIVATE);

// 从共享首选项中检索存储的字符串
String arrayString = sharedPreferences.getString("array_key", "");

// 将字符串转换回数组
String[][][] retrievedArray = new Gson().fromJson(arrayString, String[][][].class);
