Hai!
In my application i want to change the listView text color in android.
How can i achieve this.
any solution will be appreciated...
ListView uses some optimizations when displaying itself, so you have to take some care when changing colors: http://developer.android.com/resources/articles/listview-backgrounds.html
You'll need to use a custom Adapter to do this. This tutorial looks pretty good: custom list view

I am using the MaterialAutoCompleteTextView component. I would like if possible to set a different background color for selected item.
This is the current UI:
I would like to achieve this:
Any idea how to solve it?
I asked in the github and the solution is update the material library and use the property MaterialAutoCompleteTextView.setSimpleItemSelectedColor() to achieve that.
(only available since 1.7.0-alpha02.)

I can't seem to find what am looking for.
I would like to know how to change all the textview fonts in all my listviews. I have my text font but when i try to apply it to code it only works for one textview1 etc.
I have been reading that i need a custom adapter to change listview styles but i don't know where to start as i am very new to android and coding. I guess am looking for a site that will get me started if anyone can help.
custom style listview for dummies lets say ;)
There is tons of information and tutorials on creating custom ListViews. I'll link some tutorials here but you really could have found what you needed by just doing a little bit more searching.

Creating Custom Adapter and ListView 2
If you have any questions or run into trouble with these I am willing to help.
Can anyone give me some idea or code if possible regarding how to change the Theme of Listview ( like the back ground color, text color, icons etc) by clicking a button for example at runtime?
I saw an example here android dynamically change style at runtime.
I want to know if something similar is possible for List Views?
Thank You.
For changing the Bg color, you can set it dynamically.
mListView.setBackgroundColor(mColor); //doc
For changing the design in your listView, you have to set some variables, then use them in your custom adapter. When you click, you change these variables and call the notifyDataSetChanged() method.
Hope this will help you.
If I understand your question correctly, you want to customize the look and feel of the rows (individually or all) dynamically. If so, using a custom adapter and overriding the getView(...) function will probably work for you.
A quick explanation is available at http://www.mkyong.com/android/android-listview-example/
Hope this helps.
Is it possible to get
this effect on a ListView in native Android? There are other alternatives like creating the list in HTML5 CSS and using phonegap etc; but it would be nice if it can be done by modifying the default behavior of Android ListView . Any ideas?
Would ExpandableListView work?
If you want rounded/beveled corners on the ListView, check this question out.
As for the individual items' backgrounds, you will probably have to make the graphics yourself.
when I show my custom listviewitem to the user, all the items and objects contained in each item have the color that I want,
but when scrooling and selecting ( with onListItemClick ), the items don't change the background color for the desired color
Sounds like you need to set the cache color hint. This blog post -- http://android-developers.blogspot.com/2009/01/why-is-my-list-black-android.html -- goes in to how to do that, and why you need to do it.
Try to add this to the onCreate method of your activity.
your_list_view.setCacheColorHint(0);
I had the same issue few days ago and it solved my problem. If you feel it is not what you need to do, then please post some code to have more details.
You will need to use selector for that. Check this http://android-codes-examples.blogspot.com/2011/03/customized-listview-items-selection.html
Read this note about CacheColorHints in the android reference guide:
http://developer.android.com/resources/articles/listview-backgrounds.html
it explains the concept behind it and why you need to set it to "#00000000" in your XML or 0 in your code.
Turns out, my view has a custom android:list<view>, and on my custom listview definition, i was using the android:background definition for each textview.
With this, I was not using the transparent or system defined color for background items on the listview. I removed this definition from my custom listview items definition, and the problem was solved.
