I have an activity that calls the
new SimpleCursorAdapter(this, R.layout.notes_row, c, from, to);
setListAdapter(notes);
I would like to add a button to the notes_row.xml that displays at the bottom of the screen "on top of" the actual notes_row allowing the user to still scroll through the list but hit the button if they want. Every time I try to change the layout of notes_row, I get the button on each item in the list. I am pretty new to Android and I think I need to inflate the button somehow so that it is layered in front of the list but doesn't impede the list, how do I go about doing that?
The R.layout.notes_row is the layout for each individual row. You will need to create a custom ListView.
Here is a tutorial: http://www.androidpeople.com/android-custom-listview-tutorial-example/
It sounds like you are adding the button to the notes_row layout. That will add it to each row.
Instead, you want to add it to the layout for the Activity. Are you extending from ListActivity? You could try adding the button as a footer to the ListView.
Otherwise, you can extend from a standard Activity and supply a layout file for that activity that includes a ListView and a Button. If you haven't yet, read through declaring layout and common layout objects to get a start on creating a layout.
If you will try to edit notes_row.xml file and add a button there it will come in each row, what you can do .. try editing the xml for the parent activity where you are trying to put you list view. In that xml you can easily put a button at the bottom

I have a ImageView with a TextView and Button. I have it currently in a custom list view, but I noticed now that I don't need to show more as one element (object). So I actually don't need a Listview to show the row (list entry). How can I show the list entry without a Listview?
You can put the elements of your custom listview item into a Layout, e.g. LinearLayout and simply add it to your activity's layout where you needed it.
You can set an OnClickListener for that layout, so user can click the whole thing.
I think you should use ListActivity. Then you can set up empty view for list. Here some tutorial: ListActivity and ListView Tips.
Also you can implement that logic with Recycler view by yourself or use library.
Here is solution from stackoverflow
I need to create a layout with three Button and three ListView,when i click on first Button first Listview should be shown in the same activity and second button second ListView so on....
How is this possible?.Can anyone help me.
Have you considered using a Tab Layout? It's easy to use and you can have three tabs showing your list views, independently.
http://developer.android.com/resources/tutorials/views/hello-tabwidget.html
Add all of them to the same activity, then set the content of the three listviews. Add onClickListener() to each button and use View.Gone and View.Visible to control the visibility of the three ListViews. Or, like Hussain pointed out, just change the content of the single ListView

I am trying to create a listview with add button on the side as shown in the right image http://developer.android.com/resources/articles/images/android.png
Is it possible to reuse this existing layout object. If so what is it called exactly? All I can find in the default listview is simple checkboxes and other listviews without buttons.
You can create your own listview by making an extra xml in your layout folder.
for example your make a textview and next to that textview a button, then inflate that.
i am trying to develop this app in android that has 3-4 buttons and a list being displayed below them. each button when clicked must reload the list with new contents based on which button was clicked.
each row in the list has a picture and two lines of text.
could some one please suggest me how do I perform the reloading part.
Attach the new adapter, with updated elements, with the listView, it will work as reloading the list view......
You could grab the list, in whatever layout it is in (ex LinearLayout) by doing a:
LinearLayout ll = (LinearLayout)getViewById(R.id.thislayout)
Remove the elements from the list as you desire using:
ll.removeView(view);
edit the view object as you want (changing the source etc) then re-add it to the LinearLayout using:
ll.addView(view);
I have created one list view.. it is having 5 items...
Now I want split the list items...
when user clickon the first listitem or focus on first item then immediately it has to show followed some text views or other things..but it has to show same list..
and agian same when he clickon or focus on the second item that first item has to be close and second item has to act some thing....
I think you need to implement the concept of "Expandable Listview", so that the clicking on one item, it will be expanded with their sub-items.
Refer the android-sdk page of Expandable ListView: http://developer.android.com/reference/android/widget/ExpandableListView.html
For having an example, check this site: http://mylifewithandroid.blogspot.com/2008/05/expandable-lists.html
Pls, check the below image, do you want to perform as same ????
If you want to do the same, it is already given in the "API-Demos" at Views/Expandable Lists/1. Custom Adapter.
Enjoy !!
The problem is that you cannot use the standard ListView in your case, because in the standard ListView, the View of each row has to be one TextView.
In your case, you need it to be at least two TextViews (The standard Text, and the one that's gonna show up onClick/onFocus).
You have to create your custom ListAdapter, and override the getView() function.
Here is a code snippet that shows how to do it properly:
Custom Adapter
In the getView(), you have to inflate the XML file that describes your List Row, and return it.
In your case, I believe your XML file should contain 2 TextViews, one visible and one invisible.
Then, to handle the clicks, you can set a onItemClickListener on your ListView in your Activity class.
The best way may be to have your Activity class implementing onItemClickListener, and to use this onItemClickListener to handle those.
In the onClick() function, you just have to set the Visibility of your hidden TextView to VISIBLE.
You need to build custom rows, and handle showing more text on each row, there is no easy magicall way of doing it, but inflating your own rows, and setting a couple of attributes visibility isnt all that hard either.
