Android 按任意项从sqlite查找id

我必须在数据库中找到“id”，我尝试了这种方法，但我无法解决它。你能帮我吗。非常感谢

listview.setOnItemClickListener(new AdapterView.XouOnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
                                long arg3) {

            String text = (String) listview.getItemAtPosition(arg2);


            Database db = new Database(getApplicationContext());
            String query = "SELECT name, id FROM tableDB WHERE name = '" + text + "'"; // I think problem is here
            Cursor cursor = db.rawQuery(query, null);
            cursor.moveToFirst();

             id_position = cursor.getInt(cursor.getColumnIndex("id"));

            go_detail();
        }
    });

我认为错误在您的

go\u detail

函数中。尝试添加一个参数，例如

go_detail（int id_position）{….}

现在，如果没有参数，它无法获取id

否。我一行一行地尝试。明确的问题是这行字符串query=“SELECT def，id FROM tuncDB，其中def=”+second+”；但是您希望如何在

go\u detail

函数中获得

id\u position

的值呢

private void go_detail(){
            Intent intent = new Intent(getApplicationContext(), Detail_page.class);
            intent.putExtra("id", (int) name_ids[id_position]);
            startActivity(intent);
}
