Cursor not binding text correctly with custom adapter

由 一个人想着一个人 提交于 2019-12-07 21:37:30
问题 My Custom Adapter that extends SimpleCursorAdapter for my ListFragment does not display the items in my database correctly. it does not display the text in the TextView, what else do I have to do to the cursor for it to show the correct text? I thought I had to override the bindView but that had no effect Setting the adapter: public void populateList(){ String[] fields = new String[] {BowlersDB.NAME}; Cursor c = getActivity().getContentResolver().query(BowlersDB.CONTENT_URI, new String[]

Android UI - add buttons dynamically to Gridview

由 喜欢而已 提交于 2019-12-07 21:07:48
问题 This is where I am stuck now. I am stuck at dynamically adding buttons to gridview. - My gridview stars with a one button. - When user clicks that button a context menu , pops up, asking user to enter info, once that is done. A block in the grid view is created with that info - This is shown in the picture I have pasted the code. I do not have clear idea on how to do it. I am assuming it will be inflating a new view and adding it to parent(layout or grid ?) view. I do not have much idea on

Format data between SQLite and ListView

由 淺唱寂寞╮ 提交于 2019-12-07 19:31:31
I'm sure there must be a simple solution to this... I have a SQLite database, and I'm using the standard SimpleCursorAdaptor to put the database into a ListView. No problems there. However, I would like to be able to format some of the data in between the database and the ListView. For example, I want to divide all the data in the "price" column by 100 (in the database a price might be "5400", I want it displayed as "54.00"). Use SimpleCursorAdapter.ViewBinder : SimpleCursorAdapter simpleCursorAdapter = new SimpleCursorAdapter(..); simpleCursorAdapter.setViewBinder(new SimpleCursorAdapter

Endless scrolling ListView

由 ☆樱花仙子☆ 提交于 2019-12-07 19:25:35
I am populating a ListView with data fetched from an online service, which provides the data in pages. Rather than providing a 'next page' button, I am attempting to automatically load the next page of data when the user scrolls near the bottom of the page. Data is fetched using an AsyncTask: class RecentTracksTask extends AsyncTask<Integer, Void, Void> { ArrayList<Track> recentTracks; @Override protected Void doInBackground(Integer... page) { try { // Get a page of 15 tracks // Simplified - getPage accepts 'page' and 'limit' parameters and returns a Collection<Track> recentTracks = new

enter multi-choice mode with nothing selected

由 自古美人都是妖i 提交于 2019-12-07 17:35:48
问题 our UX asks for a button to start multi-choice mode. this would do the same thing as long-pressing on an item, but would have nothing selected initially. what i'm seeing in the code is that i cannot enter multi-choice mode mode unless i have something selected, and if i unselect that item, multi-choice mode exits (contextual action bar closes). i've also tried this in other apps (gmail), and it works the same way. is there a way to be in multi-select mode, with no items selected? thanks. 回答1:
