Android Competency Center

Hi,
I am creating an application in android. I have already done this application using J2ME.
This application completely uses List Views for every screen.
Basically i am parsing XML for every List View.
But i do not know how to go from one screen to another when i click on different items on the List.

Please advise. I am stuck for nearly a week now.

Hi Vijay,

You have to use Intent and the function onListItemClick.
Suppose you want to transfer the control to class SecondActivity from Class FirstActivity

protected void onListItemClick(ListView l, View v, int position, long id) {
super.onListItemClick(l, v, position, id);

….
Intent i = new Intent(this,SecondActivity.class);
//SecondActivity is the name of the next screen you want to //display upon the click on this list
startActivity(i);
….

}

For more on intend see docs folder in Android sdk installation

and also see this

Hi there,

I’m happy to find your blog!! It must be helpful for me!
I downloaded android source from “http://source.android.com/download/”.
I found some tips in “http://blog.michael-forster.de/2008/12/view-android-source-code-in-eclipse.html” to finish it.
So I can see android’s class files when I click on class name with CTRL key.

Now I’d like to see the android native application source and debug them.
I wonder if it’s possible with Eclipse on window OS..

Thanks..!!

I am interested in the complete list of what you can do on the Android platform. I.e.

1) utilize location based gps
