问题描述
如何创建一个列表阵列(列表中显示第一字母时,滚动)用光标数据?
How can I create a list Array (the list display First Alphabet when scroll) with the cursor data?
推荐答案
通过每一个元素进去的光标
,并逐个添加它们一到的ArrayList
。
Go through every element in the Cursor
, and add them one by one to the ArrayList
.
ArrayList<WhateverTypeYouWant> mArrayList = new ArrayList<WhateverTypeYouWant>();
for(mCursor.moveToFirst(); !mCursor.isAfterLast(); mCursor.moveToNext()) {
// The Cursor is now set to the right position
mArrayList.add(mCursor.getWhateverTypeYouWant(WHATEVER_COLUMN_INDEX_YOU_WANT));
}
(更换 WhateverTypeYouWant
与任何类型你想的的ArrayList
和 WHATEVER_COLUMN_INDEX_YOU_WANT
与您希望从游标来获取值的列索引。)
(replace WhateverTypeYouWant
with whatever type you want to make a ArrayList
of, and WHATEVER_COLUMN_INDEX_YOU_WANT
with the column index of the value you want to get from the cursor.)
