I would like to know if its possible to drag an item from the ListView and drop onto the Button. After dropping onto the button the text on the button will be changed.
Is it possible to drop an item onto the Button?
you can achieve that behavior with Animation except that i don't believe there is quick easy solution

As for making a popup appear on button click, use dialogfragments.
We have multiple checkboxes, as shown below:
We want the user to be able to select first checkbox for A,B,C, by him dragging over the checkboxes.
Is this possible in android?
Yes, you could do something like that. You'd have to first start a drag operation and drag a view. If you tried to do it with just your finger, it would be an exercise in gesture detection. But dragging a view would be simple.
Using this tutorial as a guide - http://developer.android.com/guide/topics/ui/drag-drop.html - you should be able to start a drag operation using a click listener on the view you want to drag. Then, as the dragged view enters the bounding boxes (you set up draglisteners on each) of a checkbox, you can set it to checked.
I have a simple soundboard which uses Buttons to represent the sounds. When a sound button is clicked. The background image is changed using the view.
Button butt = (Button)view;
butt.setBackgroundResource(buttons_on[media]);
buttons_on is a int[] representing the drawables of the buttons.
This all works perfect, but I also use a FragmentActivity to create a paged App. The App has 4 different pages which you can swipe through. When I change a button using the above code and swipe two pages to the right and than swipe back. The image of the button has changed back to it's default defined in the page.xml.
How can I prevent this behavior?
change the Buttons to ImageButtons and setting the src?
somehow prevent the page from reloading
Instead of doing that you should look at how to use a StateListDrawable. It will simplify your approach.
After dragging and dropping a button in the design view, do I need to set the button to be visible in the source code? After testing it, the buttons do not appear.
befor using Drag and drop in netbeans you have to Drop Panel in form,then drop other component in the panel. for example , you want use commandButton. first you should Drag and drop panel in form then drop commandbutton in that panel.
very easily...
I'm making a fairly simple text editor, and I have a question about my style buttons. When I highlight text and click my "bold" button, the text bolds as expected, but my selection is not longer visible. I can still unbold the selection, italicize it, or underline it, but you just can't see what is selected. So, I'm wondering if there is a setting that will allow me to click the button, but keep my selection? I tried a JMenuItem instead of a JButton, and that seemed to work, but then it made my toolbar look quite bad. Sample code below.
//frame and pane creation up here
JToolBar tool = new JToolBar();
JToggleButton boldButton = new JToggleButton("Bold");
boldButton.addActionListener(new StyledEditorKit.BoldAction());
tool.add(boldButton);
Any help is appreciated.

boldButton.setFocusable( false );
As you noticed, the selection is still there but clicking on the toolbar button removes the focus from the text pane and hides the selection. You need to set the focus back using requestFocus. However, you will need to write your own action listener to add the focus code - you could extend BoldAction to do this.
