android - 带有列表的 SQLite 查询

Question

我正在将ArrayList<Integer>SQLite Query 传递给它，它像这样打印，但我没有得到任何输出

SELECT * FROM categoriesData WHERE categoryid IN [49, 67, 23]

显示空值

但如果它在圆括号中，它会打印值。

SELECT * FROM categoriesData WHERE categoryid IN (49, 67, 23)

如何使它们成为圆括号

Answer 1

String query = "SELECT * FROM categoriesData WHERE categoryid IN " + Arrays.toString(myList.toArray()).replace("[", "(").replace("]", ")");

Answer 2

    String query = "SELECT * FROM categoriesData WHERE categoryid IN " +
                   "(" + yourArrayList.get(0) + ", " +
                         yourArrayList.get(1) + ", " +
                         yourArrayList.get(2) + ");" ;

希望能帮助到你。
