title: Selecting/highlighting multiple items in listview with custom adapter - Android
body: <p>I followed a good tutorial, with some changes, to create a custom ListView that will allow me to display multiple images for each row in my ListView. What I would like to do is highlight by selecting multiple items in the list and then perform some sort of action to all of those list items by selecting an option on my Options Menu. However, the problem I seem to be running into is that I cannot select multiple items, even though I have added <code>android:choiceMode="multipleChoice"</code> to the ListView in the .xml file. I realize that this can be done using check boxes or radio buttons, but I would prefer to avoid that. I have attached my source code below. Any help would be appreciated. Lastly, thanks to <a href="http://custom-android-dn.blogspot.com/">http://custom-android-dn.blogspot.com/</a> for a great tutorial. Thanks.</p>
