No - this is an unnecessary layer that is quite expensive in memory and CPU resources. You have an Activity that probably has a call to setContentView(v). Here 'v' can be any View. It does not have to be a layout. In general, View widgets do not need to be declared inside layout widgets (layouts are ViewGroup instances). For example ---list.xml--- <?xml version="1.0" encoding="utf-8"?> <TextView xmlns:android="http://schemas.android.com/apk/res/android"; ... /> > > On Dec 30, 2:51 pm, jotobjects <jotobje...@gmail.com> wrote: > > > Does android.widget.TwoLineListItem do what you want? > > > BTW - looks like the outer LinearLayout is unnecessary in list.xml and > > listadapter.xml. > > > On Dec 29, 5:41 pm, Mystique <joven.ch...@gmail.com> wrote: > > > > Hi, > > > I have an app that I mine data with an ArrayList and load to an > > > ArrayAdapter to display as listview.
