How to customize android spinner like this, and also the item of spinner also will look like this width. Is it possible to do this? If yes means tell the way. Otherwise what will do?
You have to create 2 or 3 state 9 patch image for the selected, pressed and default state of the Spinner and then use them as background of the Spinner.
Have a look at this post which beautifully explain all the process.

I created with Android Studio 1.0 a new project and added a spinner. But the result doesn't look very understandable. It's not clear enough that the spinner is a clickable object. It shows only the top element and a small arrow down. My default Spinner
I've implemented the spinner the way the developer-page from android describes.
How can I change it to something, that looks more like this.
I've tried things like setting the background color, but in the result the little arrow disappears.
How is it possible, that my default layout looks so different from the declared one by developer.android.com?
In any case you can create your own custom spinner or set some selector to it. For example: http://androidexample.com/Custom_Spinner_With_Image_And_Text_-_Android_Example/index.php?view=article_discription&aid=84&aaid=107
My problem is straight-forward.
I have a default spinner in android API 19.
But i want to customize it to make it have a border and also a triangular shape at the end pointing at the bottom. (Like the spinner with old versions of android).
I have this spinner: http://androidopentutorials.com/wp/wp-content/uploads/2014/03/android-4-spinner.jpg?f9f065
But I want the spinner to be like this: http://lh4.ggpht.com/-DwIrYX29Rzg/TsPtjLkIkLI/AAAAAAAAAjs/m3GvtKmRDGo/firstLayout_thumb.png?imgmax=800
How can i customize the spinner?
I have searched for tutorials online but i got only those custom spinner with image and text together.
Have a look at this tutorial: http://www.mokasocial.com/2011/03/easily-create-a-default-custom-styled-spinner-android/
Basically, what you need is a 9-patch that you will use as a background of your Spinner.
The steps are fairly simple:
Get your 9-patches ready.
Create a <selector> that represents the stats of your Spinner by using these 9-patches.
Set the <selector> as the background for your Spinner.
The caveat to my approach is that you will have to set the background for every Spinner you use. If you want to 'do it once, use it everywhere', follow the tutorial approach where the author uses a custom theme.
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.
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.
In my app I'm using a spinners to let the user select an item from a list. Everything works fine but I'm not really happy with the look of the spinner. As you can see in the image below it has the same design as a normal button.
What I want is a spinner which looks more like a normal text field. So I browsed a little bit through the drawable folder of the Android sources and found out that the spinner background should normally look quite different. I append an image of a spinner with the background image as I found it in the drawable folder. Although the spinner in the image is focused, I think you can see the difference between both spinners.
Now I'm wondering why the my spinner (first one) doesn't have the same design as the second one as II didn't changed any attributes which are related to the design of it. Where does this button like design come from?
The first spinner screen depicts the default spinner.
So the answer is that you've expected the wrong behavior. You can however create your own spinner look.
Looks to me that the second spinner was there in the earliest versions of the android sdk and just remains there as is.
