如何在Android中存储布尔选择

SharedPreferences sharedPreferences = getSharedPreferences("MyPrefs", Context.MODE_PRIVATE);

SharedPreferences.Editor editor = sharedPreferences.edit();

editor.putBoolean("isChoiceSelected", true); // 存储布尔值
editor.apply(); // 提交更改

boolean isChoiceSelected = sharedPreferences.getBoolean("isChoiceSelected", false); // 默认值为false

editor.remove("isChoiceSelected");
editor.apply();

public class MyDatabaseHelper extends SQLiteOpenHelper {
    private static final String DATABASE_NAME = "my_database";
    private static final int DATABASE_VERSION = 1;
    private static final String TABLE_NAME = "my_table";
    private static final String COLUMN_NAME_CHOICE = "choice";

    public MyDatabaseHelper(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
    }

    @Override
    public void onCreate(SQLiteDatabase db) {
        String createTableQuery = "CREATE TABLE " + TABLE_NAME + " (" +
                COLUMN_NAME_CHOICE + " INTEGER)";
        db.execSQL(createTableQuery);
    }

    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        // 升级数据库时的操作
    }
}

MyDatabaseHelper dbHelper = new MyDatabaseHelper(context);
SQLiteDatabase db = dbHelper.getWritableDatabase();
ContentValues values = new ContentValues();
values.put("choice", 1); // 存储布尔值
db.insert(TABLE_NAME, null, values);
db.close();

MyDatabaseHelper dbHelper = new MyDatabaseHelper(context);
SQLiteDatabase db = dbHelper.getReadableDatabase();
