In onItemClick Follow [this video] Which seems to be good tutorial for a start. You don't open a xml. You navigate to a different activity based on the position of List item click. Each activity will have its own layout set. The below should work try { String val = values[postion]; Class ourClass = Class.forName("com.example.listview."+val); Intent intent = new Intent(MainActivity.this,ourClass); startActivity(intent); }catch(Exception e){ e.prinStacktrace(); } Make sure you make an entry for Activities in manifest file Edit: public class MainActivity extends ListActivity { String[] values = new String[] { "Android", "iPhone", "WindowsMobile", "Blackberry", "WebOS", "Ubuntu", "Windows7", "Max OS

Cites 3D-kreativ · 2013-02 · Stack Overflow · on “Change background color in list menu”
I'm building a simple app with a listmenu from a video tutorial by The new Boston [this video] And in that lesson you create this listmenu without any layout. It's all working for me, almost, the menu is in the activity, but I can't see any text in the menu. The text is visible just when i press on one of the menues option. The background is always white when I run my apps on the AVD or my phone. Is there a way to change the background color and the color of the text, when you create an listmenu in an activity without the layout.xml? Or could there be something else that is wrong? Preciate som help. Thanks! EDIT: I'm not sure if it's the background color of the activity or the buttons in the menu

I'm making an app where a user can pick a city in a giving area, and this brings up a listview of events in that given area. I'm using this video guide as a way to help me [this video] . Unlike the person in the video, I need to have my list say one thing, and the results say another. I'm having trouble finding a way to change my String before it gets to the try statement. For example, I want to change "City history" to "beachcity" (so it takes them to this page), "Fort Macon" to "fortmacon", and so on. That away the user sees something they can understand. Is there a way to do this? At worst, is there a way to change this with some if statement? Below is the JAVA code public class Alantic extend
