Android :: Drag Items Around In A ListView To Change Their Order?

Sep 1, 2010

Let's say I have a ListView of items:

Cat
Dog
Mouse

And these are bound to the ListView via an adapter to a database.

What I want to be able to do is to be able to re-order the list view,. For example I want to somehow drag "Mouse" up to the top of the list above "Cat". Once I have an order set, I then want to "save" the list and its order back to the database.

Is there any way to do this? Has someone made such a custom ListView that I could use? The only alternative I can think of is to long press on a list view item and have a "Move up by one", "Move to top", etc. context menu that moves items around in the list.

Android :: Dynamically Change Text Color Of A TextView Inside A ListView

Nov 18, 2010

I'm trying to create a game lobby for a project, and I'd like the game's status text to be a different color: red for an "[IN PROGRESS]" game and green for a game that's "[Waiting for x players]". The ListView will be populated with data, and each ListView item will have a game ID and then immediately to the right of that the game's status.

Right now I'm essentially using the Hello ListView code to create my ListView.

(In constructor)

CODE:...........

Then, I have a refresh button that obtains data from our database. It will get two Strings, one for the ID of the game, and the other for the status of the game. If the game status is 0, then it's still waiting for players. If the game status is 1, then the game has started. So, I create a gameItem to add to the gameList:

CODE:.............

This is where I'm stuck. I don't really understand how I can alter the specific TextView when I create the gameItem or when I add that to the gameList. There isn't a way I can see of accessing the TextView's properties. I see how the text of the view is set (through the mapping of the strings to "line1" and "line2", but I don't know how to change any of the properties.

Android : Dynamically Add Items To Preferences?

May 12, 2010

we have an XML file placed in the res/xml folder containing our preferences.

Is it possible at runtime to add new items to the preferences.

Example:

The user starts the app and the preferences consists of:
America
- New York - Los Angeles - Chicago

Where all the cities are CheckBoxPreferences.

Then the user performs some actions in the application and this triggers that two new cities are added to the preferences:

America

- New York - Los Angeles - Chicago - Seatlle - Washington

Anyone that know if it possible at all and how to do it?

Android :: ListView Items Not Responding To Tap

May 28, 2010

I'm just getting my feet wet with Android and have built a UI that contains a TabHost with three tabs. Each tab is powered by its own Activity. The first Tab contains a listview with a prepopulated set of rows and is built from a custom ArrayAdapter.

The problem I'm running into is that none of the ListView rows are tappable. In other words, when I tap on them there is no orange selection. If I use the scroll ball on my Nexus One it will select, but any touch gestures don't seem to be responding. All the UI is being handled using XML files with a main.xml housing the TabHost -> LinearLayout -> TabWidget/FrameLayout and a nearby_activity.xml file containing my ListView UI

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"............

Android :: Possible To Set Items In Listview Invisible?

Jul 20, 2010

I have a listview that's using a custom adapter. I want to dynamically show/remove items from the listview. I've tried everything inside the getView() method in my view adapter. I've tried doing setVisiblity(View.GONE) on the view I'm returning. And it infact doesn't draw the view, but it allocates space for the view and it's just a blank black space.

Is this even possible to set items in listview invisible?
