I'm looking for a way to dynamically change an elements properties.
For example I want the user of my app to be able to enter a value within my program that will change android:layout_marginTop="blabla" to whatever I want. It doesn't specifically have to be that property, I want to be able to change any property of any element. Is there a way to do this?

I'm making out a few menus for my Android App and throughout there is a standard textview that is repeated 5 times, only changing the android:text tag each time, everything else is the same.There are a good number of properties on this and it feels very inefficient to be copy/pasting all these for each of the textviews.Is there a way I define the common properties just once and add them to each TextView element?

Now when I'm trying to change tab in my ListActivity tab by clicking on one of the items it doesn't do anything and stays on the ListActivity tab. Perhaps I shouldn't use onResume() here. Basically I want to go to first tab when I click on one of the items in the list. Please help!
I'm using BaseExpandableListAdapter, and there is a drop-down button (looks like an arrow) on the left side for each parent item to indicate that you can expand that item to view child items. The question is: How can I change the properties of that drop-down button such as its position? I basically want to move it a bit lower in each parent item.
View 2 Replies View RelatedI am wondering if anyone else is encountering this issue (or if its just me). I converted an app I have been working on from using a regular view to using SurfaceView. The app accesses listviews to change properties of the elements I am drawing on a canvas. The listviews called from the SurfaceView version draw over themselves mis-registered when I scroll long lists quickly. If anyone out there has had a similar problem and/or has an idea what might be going on and/or has a suggestion as to how to fix this.

I have three tabs in my Application. On an event under one Tab, i want to change the title of an another existing Tab. This is the title that we provide while adding the tabs to the TabHost.
Eg: TabHost.addTab(tabHost.newTabSpec("Tab2")).setIndicator("I need to be Changed dynamically").setContent....
In the above example, the title of the tab2 that i provided under setIndicator(), should be changed dynamically.
Is there any way to accomplish this.
I have an Android application which has four tabs (I use a main TabActivity with TabHost and TabSpecs).
In one of my sub activity (activity opened in a tab), i need to open a tab not by clicking on the tab title and i don't know how to do this.
For example, i have a button in my activity and when i click on it, it opens a different tab.
For the moment, it is what i do:
Intent intent = new Intent(myActivity.this, myTabActivity.class);
intent.putExtra("ComeFrom", true);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);
Then in the TabActivity, if i get true reading the "ComeFrom" extra i open the wished tab but the problem is that it kills all the other activity. So, if someone knows a better (cleaner) way to do that trick.
I have a tab activity with 3 tabs. Each tab has a default icon.
I want these icons have to be changed dynamically on each tab selected.
I mean, each tab has two icons, one for on tab select, another for on tab deselect.
Can any one please suggest me how to do it?

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.
Can I modify android.R.layout.simple_list_item_1? For eg., I want to change the text color of the textview inside the listview dynamically. For this, I need to get to the textview and change its color.. How can I do that?
