Lets say I have a list on screen, which I always want to be usable. I also want a small image or textview to slightly overlap the listview. Is anything this possible without using absolute layout parameters?

I've never seen it in any android app or tutorial, but there are things like this in many iPhone apps. It adds a nice touch.

(Also, I don't have any code to show because I'm not sure where to start)

Relative Layouts also allow things to overlap. Views declared later in the xml will be on top. I believe that aligning view edges and use of margins should allow you to achieve this affect without great difficulty.

You could use RelativeLayout and set for example android:layout_marginTop="-50dip" android:layout_below="@id/my_list".

As well as RelativeLayouts, you can also use FrameLayouts to stack objects. Other than the z-order (last object declared = highest z-order), the child objects don't depend on the positioning of other objects in the group, so you can just set margins or gravity to position them.

So in your instance, just declare a TextView after your ListView, and position it wherever you want. It won't interfere with the ListView's positioning, and it will sit on top.

  • Thanks for the reply. I'm going to check it out. I have used z-indexes in web-development and they are pretty simple. i didn't know that they were in Android. Thanks. – NotACleverMan Apr 27 '11 at 13:50
