如何在安卓系统中进行SQLiteDatabase包含搜索

// 创建数据库和表
public class DBHelper extends SQLiteOpenHelper {
    private static final String DATABASE_NAME = "mydatabase.db";
    private static final int DATABASE_VERSION = 1;
    private static final String TABLE_NAME = "mytable";
    private static final String COLUMN_NAME = "name";

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

    @Override
    public void onCreate(SQLiteDatabase db) {
        String createTableQuery = "CREATE TABLE " + TABLE_NAME + " (_id INTEGER PRIMARY KEY AUTOINCREMENT, " + COLUMN_NAME + " TEXT)";
        db.execSQL(createTableQuery);
    }

    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        // 处理数据库升级
    }
}

// 插入数据
public void insertData(String data) {
    SQLiteDatabase db = dbHelper.getWritableDatabase();
    ContentValues values = new ContentValues();
    values.put(DBHelper.COLUMN_NAME, data);
    db.insert(DBHelper.TABLE_NAME, null, values);
    db.close();
}

// 执行查询
public Cursor searchData(String keyword) {
    SQLiteDatabase db = dbHelper.getReadableDatabase();
    String[] columns = {DBHelper.COLUMN_NAME};
    String selection = DBHelper.COLUMN_NAME + " LIKE ?";
    String[] selectionArgs = {"%" + keyword + "%"};
    Cursor cursor = db.query(DBHelper.TABLE_NAME, columns, selection, selectionArgs, null, null, null);
    return cursor;
}

// 使用查询结果
Cursor cursor = searchData("keyword");
if (cursor != null && cursor.moveToFirst()) {
    do {
        String data = cursor.getString(cursor.getColumnIndex(DBHelper.COLUMN_NAME));
        // 处理数据
    } while (cursor.moveToNext());
}
cursor.close();
