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 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.)
