android-listview

I've made a navigation drawer in my app. Inside my navigation drawer is a ListView . It's a simple list view with text items. The Gmail android app has a ListView with headers. (source: phonedog.com ) As you can see, the words: INBOX, RECENT LABELS, ALL LABELS are headers. I would like to implement exactly those type of headers into my app. Is this feature an inbuilt android thing or do I have to create something custom. If yes then how. Let me know if you need any more info. Thanks in Advance. 来源： https://stackoverflow.com/questions/19341033/android-navigation-drawer-listview-headers

I struggle with a common problem however I can't see the solution to it. What I'm trying to achieve is to display the list of questions (they come from parsed JSON) and radioGroup under each. I've manage to get questions list displayed. Now when I check the buttons and scroll down the list the upper buttons are loosing it state.

The user can add any number of downloads, but download will start one after another i.e. next download will start only after the completion of present download. The user will navigate away from the activity showing download progress in order to add new downloads, and when new file to be downloaded is added, the application navigates back to the activity showing download progress, where it will show the progress of the download, previously added, and keep the presently added file as pending download. As soon as the downloading completes, pending download will start downloading. In this way the

Why do listview.getChildCount() and adapter.getCount() return different values? I have an onScroll method and from within it, if I call the methods above, each return different values. Does anyone know why? ListView.getChildCount() returns the number of Views on the screen. Adapter s getCount() returns the total number of objects in your list. getChildCount() getCount() You might have 50 String s in say an ArrayAdapter but only 10 are drawn on the screen at the current moment so your ListView count will be 10 but your Adapter count will be 50. adapter.getCount() returns total objects count

I have a problem understanding why is my ListActivity and its corresponding listView empty when I call close() method on cursor object? Let me explain myself a bit... I retreive some values from a DB and get the result in my cursor object. After that I create my SimpleCursorAdapter and bind column from db with a field in my listView . Works like a charm, but... If I call cursor.close() at the end of onCreate() method my listView is shown empty? If I log the values from cursor to LogCat they're there until calling cursor.close() and that makes perfect sense, but why is the listAdapter emptied
