Why is CursorAdapter different from BaseAdapter?

由 天涯浪子 提交于 2019-12-07 11:12:37
问题 I would like to ask why CursorAdapter splits the process of creating a view and populating it with data into newView() and bindView() while BaseAdapter only does this with getView() ? 回答1: From Source code of CursorAdapter.java, CursorAdapter extends BaseAdapter . And you can see getView() function implementation: public View getView(int position, View convertView, ViewGroup parent) { if (!mDataValid) { throw new IllegalStateException("this should only be called when the cursor is valid"); }
