Without going into details, I need to attach a drawable at the bottom of last item in ListView. The limitation is I can only use styles & themes to achieve it. No Java code is allowed. I also can't add any item to the end of the adapter.
How can I do it? All hacks are welcome. Thanks!
Added: Or maybe it's possible to attach footerview to the listview via xml?

I'm not averse to rolling my own, but wanted to make sure I'm not overlooking pre-existing functionality.
I need a ListView where each View can take a highlighted state and then be un-selected by virtue of selecting a different item in the list. Basically a radio list.
I totally understand how to build one myself, so please don't jump down my throat with "what have you tried"... I'm just asking if I'm overlooking a pre-built tool already baked into the Android toolkit.
Either add attribute android:choiceMode=singleChoice in layout.
or,
call setChoiceMode(AbsListView.CHOICE_MODE_SINGLE) on ListView from your code.
If you need item views to highlight on selection, use android.R.layout.simple_list_item_activated_1 or android.R.layout.simple_list_item_activated_2 for item layout.
What's the easiest way to create separate preferences for each item in an Android listview? I found this question, but it's kind of general. Could anyone be more specific, possibly show a quick example?
If you want to do this, you should write some code into your adapter getView method.
You can check the position (with an if-clause) in the method and add a custom desgin/layout depending on the position.
If you use a LinearLayout or RelativeLayout in your ListView item XML you can fill this programmatically in the getView method with all the widgets (edittext, checkbox, etc) you need.
I am trying to create a screen where I get two items from SharedPreferences and display them to the screen, and then display a list via an adapter.
What I am not sure about is how to structure the layout xml file for this. Any suggestions how to do that?
Thanks!
You can have the main layout with a listview. Then you can have a sub layout for each row of your list. This row layout, let's call it row_layout.xml may have two text areas if your items are text or it may have a text area and a checkbox button if that's what you want. Basically, whatever you want to display in a single row of your list.
Read up a tutorial, here's one: http://www.vogella.de/articles/AndroidListView/article.html
Take a look # MergeAdapter, you can also create a view only listitem and add these item as header to the list
I am not sure what you mean. Are you asking for examples of layouts with two textviews that can be updated via sharedprefs, with a ListView in the activity? Or just suggestions? An easy way to get started would be to use the Eclipse Android plugin that has a layout designer in it. Here is a tutorial on how to use it http://mobile.tutsplus.com/tutorials/android/android-layout/ Its pretty easy and straight forward.
I have a Custom ListView in my application and it has some TextViews inside it to which the styles are provided at run time. When I scroll down the ListView and again scroll up, the styles given previously to the TextView changes to some different style.
Is there any way to prevent this?
I think, putting all the code here will make the page look ugly. So kindly follow these links for code-
MyAdapter.java
CustomListItem.java
Do you use custom Adapter? Maybe it is some issue with incorectly reusing convertView, can you post the code?
Or maybe it is just changing background color? In that case simple:
android:cacheColorHint="#00000000"
in ListView's XML will do the work.
I found a way to fix it. Just set the TextView with some default style in the "Convert View" like
textView.setTextAppearance(context , android.R.style.TextAppearance_Small);
in the ViewHolder constructor and in your method you use to set the elements to default state.
I'm developing an app on Honeycomb with a ListView. When using a normal ArrayAdapter to feed the ListView content, I can pass it a built-in layout such as Android.R.layout.simple_selectable_list_item. This creates a clickable item with a nice fading animation when selecting an item that is consistent with the overall Honeycomb feel.
However, if I decide to use my own custom layout (or to create a custom adapter), I no longer have any animation when focusing on or selecting an item in the ListView. I could construct my own animation, but I would prefer to use the default Holo theme when developing for Honeycomb for simplicity and consistency.
I'm at a loss for how to do this and haven't been able to find anyone else with my struggle (perhaps I'm searching the wrong terms, or am missing something obvious!). Does anyone have any suggestions? I figure it involves identifying some sort of style or theme in the XML file for the layout, but I haven't figured out where to put that or what the contents might be.
Thanks!
Got it: I had to remove all references to android:listSelector and android:background for my ListView. Then I added
android:background=?android:attr/listChoiceBackgroundIndicator
to my top-level view for the ListView row layout.
