Question

I want to make a menu, which contains 4 different LinearLayouts.
Top one has title, second one has description, the third one has 3 ImageViews, which have event onClick, and the fourth one has a Button which also has onClick event.

Somehow, android doesn’t like it, and forcing me to use ListView.

The exception message is: java.lang.RuntimeException: Your content must have a ListView whose id attribute is ‘android.R.id.list’

I have already tried to use ListView, and it didn’t work as I expected. For example, the 3rd layout, which has 3 buttons, the events are not working for each ImageView, but instead on the row of the ListView.

What can be done?

Displaying my layouts xml files:

options.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="fill_parent"
    android:layout_height="fill_parent" android:id="@+id/optionsLayout"
    android:background="@drawable/bg" android:layout_gravity="center">

    <include  layout="@layout/options_layout1" android:id="@+id/optionsLayout1" />
    <include  layout="@layout/options_layout2" android:id="@+id/optionsLayout2" />
    <include  layout="@layout/options_layout3" android:id="@+id/optionsLayout3" />

The problem is not the xml, the problem is somewhere in the code. You use a specific class which expects an ID R.id.list to be in your layout. Probably your Activity still extends ListActivity? This Activity needs an R.id.list in it’s layout.
