how to set multiple text views with radio button in list view single choice mode in android using simple adapter

I have problem in list view with single choice mode. I want to display three text views with one radio button in list view. list view working properly. The problem is single choice mode. i want to select only one list item at a time rest of thing unselect mode. I searched last three days still i won't get any idea. Could you please help me. Thanks in advance.
You could make a variable that saves the radiobutton chosen.
In each radiobuttons onclick you could set the variable value and set the rest of the radiobuttons to unchecked.
Hints:
in the radiobutton xml add: android:onClick"method name"
In the method add View view as an argument (example: public void clickMethod(View view).....)
Im not sure if you can display 3 textviews and a radioButton without customize ArrayAdapter
but if you have succeeded to build the list you can do the following
1- remove the focus from the child elements(radioButton and textviews)
you can do this from the xml [android:focusable="false"] and for the listview [listview.setItemsCanFocus(false)]
2- make the radioButton not clickable from xml[android:clickable="false"]
3- create a variable to hold the clicked item (in the custom adapter) and make public method to update this position
4- create OnItemClickListener for the listview, update the clicked position in the adapter
and call adapter.notifydatasetchanged
5- be sure to in getView method to make the radioButton unchecked and make the view at that position is checked

Button onClick and ListView onItemClick

I got a ListView and I populate it with the view containing buttons. I set onClick listeners to the buttons from the adapted, but when I click the concrete item of the ListView - nothing happens. So, we can say only buttons onClick Listener is called, when I need listViewItem to be clicked.
What to do?
Set to your button in xml file: android:focusable="false"
This is because your Button takes focus. So now you can use both onClick for your buttons, and onItemClick for each row in ListView, by telling it that Button should not be focusable.
you need to set on item click like this listView.setOnItemClickListener();
It is better to do the onlcick on listview item only.You can set some flag and toggle between the functionalities.

nothing happens when i click on the first item in android spinner. how do i fix that?

When I click on the first item in the spinner, or the default one, the spinner just collapses. All other items perform desired action. How do I get the first item to fire an action?
You are having this problem (assuming you have implemented the setOnItemSelectedListener() for the Spinner) because Spinner calls the onItemSelected() only when you change the Selection, in other words select a new item in the Spinner. Hence the Spinner simply collapse when you select the default selection.
Hope this explanation helps.

Spinner resets its value when scrolling up

I have a ListView, with different custom rows.
The last row contains a TextView and a Spinner. The Spinner works ok (when clicked the dropdown list is shown, when I choose an option it appears in the Spinner's prompt), but when I scroll up the list, the Spinner changes its value to the value in the first position (ie the string at position 0).
Why is this happening? And what can I do to stop this?
it will its the property create custonbaseadapter set getview and newview method
Advance List
Custom Apdapter

ListView Item and OnClick problem

When you touch some grid or listview items in an android app, he change the background color telling you that you have pressed it.
I'm having a problem in my app. When I create that a listview for instance, and I press it in my phone, he change color, but if I set the OnClick property, the item dont change it color. Whats wrong? The OnClick works as its suppose.
Thanks
Generally with ListView you want to use an OnItemClickListener.
This gives you a chance to perform an action based on the position in the list that was clicked.
If you need access to the view adapter from within onItemClick then you can use AdapterView#getAdapter() on the AdapterView that is supplied to you.
