android : customer List Adatper + ArrayList

Question

Team,

Could you please help me debug the issue?

ActivityAdapter activityAdapter = new ActivityAdapter(this,activityList); Log.d("list", "List Display - 1");

    setListAdapter( activityAdapter );
    Log.d("List", "list done");

It's throwing exception at the time of setListAdapter,

Thanks in advance,

Answer 1

java.lang.RuntimeException: Your content must have a ListView whose id attribute is 'android.R.id.list'

Does your XML view file contain a proper id field in the format: android:id="@id/android:list for the corresponding ListView tag?

Answer 2

You're using a ListActivity, which requires you to have a ListView in your content XML with the id "@id:android/list"

See the documentation for ListActivity for more details.
