问题 I have different colors for different lines in the ListView, by setting the color of textbox depending on the line number (in getView() of Adapter). Now when I manually scroll the ListView upwards the correct color is displayed in the bottom lines that get revealed. But when I use scrollTo, this doesnot happen, all lines revealed have the same color (they are not updated). Has anybody faced this issue? This seems baffling! 回答1: ListView#scrollTo doesn't scroll the list contents. (It's a

问题 The data which is displayed from the database in the form of listview (here listview with headers having disabled onClick of headers).

问题 I looked at this question however, it did not help solve my problem: Resources$NotFoundException: Resource is not a Drawable I'm using ActionBarSherlock (version 4.4) within my app for compatibility in older versions. My app runs perfect on 4.1.2 but it crashes on 2.3.3. The app runs all the way up to the point of mDrawerLayout.closeDrawer(mDrawerList); then it crashes after that.

问题 I see a need in my project to move from ListView to RecyclerView. I am facing some design issue. In my current ListView implementation I am using CustomView instead of inflating there. Here is my current getView() public View getView(int position, View containerRow, ViewGroup parent) { CustomView customView; if (containerRow == null) customView = new CustomView(mContext); else customView = (CustomView) containerRow; DataModel dataModel = getModelForPosition(position); if (dataModel != null) {

问题 I have a ListView with a few EditTexts in each item. I have no issues with a hardware keyboard, but things freak out a bit with the soft keyboard. I have two issues. When I first click on an EditText, it briefly appears to have focus but then loses focus once the keyboard has shown. I must then click the EditText again to get focus.

问题 I'm adding a footer and header view to a ListView by using the methods setHeaderView() and setFooterView() and a ViewInflater . That works quite well. But how could I prevent the header or footer view from firing onListItemClick events? Of course I can catch the event and check whether it came from a header or footer, but this only solves one part of the problem, as header and footer got still focused when clicked. 回答1: Simply use the ListView#addHeaderView(View v, Object data, boolean
