@Override

您可以对每一列使用 LIKE 查询和循环

像这样:

    public Cursor searchDB(String query) { 
    return db.query(true, DB_TABLE, new String[] { KEY_ROWID, KEY_COLUMN1, KEY_COLUMN2,
    KEY_COLUMN3 }, KEY_COLUMN1 + " LIKE" + "'%" + query + "%' OR " + KEY_COLUMN2 + 
    " LIKE" + "'%" + query + "%' OR " + KEY_COLUMN3 + " LIKE" + "'%" + query + "%'", 
    null, null, null, null, null); 
} 

希望对你有帮助
