Problems with AdapterView and addView

Question

I want some text images / buttons / spinners, as well as a ListView containing the parsed data, to be displayed in the class below. However, listview / adapter / addview cause certain problems. Here is the error I get:

java.lang.UnsupportedOperationException: addView (View, LayoutParams) is not supported in AdapterView

I feel this is related to my xml files, but Im not too sure. Here is my code:

public class StatisticsScreen extends ListActivity{ private List<Message> messages; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.statisticsscreen); loadFeed(); //other textviews and listeners added } private void loadFeed() { try{ BaseFeedParser parser = new BaseFeedParser(); messages = parser.parse(); List<String> titles = new ArrayList<String>(messages.size()); for (Message msg : messages){ titles.add(msg.getTitle()); } ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.xmldatarow,titles); this.setListAdapter(adapter); } catch (Throwable t){ Log.e("AndroidNews",t.getMessage(),t); } } 

My xml screen statistics:

 <ListView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent"> <LinearLayout android:id="@+id/statsviewlayout" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="@color/black"> //other layouts/textviews/buttons added <include layout="@layout/xmllayout" android:id="@+id/xmllist" /> </LinearLayout> </ListView> 

xmllayout xml:

  <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content"> <ListView android:id="@+id/xmllist" android:layout_width="wrap_content" android:layout_height="wrap_content"/> </LinearLayout> 

xmldatarow is a simple text file.

EDIT:

Ok, so I updated some files, and I get an exception exception at runtime:

Your content should have a ListView whose attribute is "android.R.id.list"

here are the updated files:

class:

 setContentView(R.layout.statisticsscreen); loadFeed(); getListView().addHeaderView(View.inflate(this, R.layout.xmllayout, null)); private void loadFeed() { try{ BaseFeedParser parser = new BaseFeedParser(); messages = parser.parse(); List<String> titles = new ArrayList<String>(messages.size()); for (Message msg : messages){ titles.add(msg.getDate()); } ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.xmldatarow,titles); this.setListAdapter(adapter); } catch (Throwable t){ Log.e("AndroidNews",t.getMessage(),t); } } 

My statsscreenlayout stil has all linear schedules with text images, etc., and I removed this from it:

 <include layout="@layout/xmllayout" android:id="@+id/xmllist" /> 

Then my other two layouts are plain text view (xmldatarow) and listview (xmllayout). So, just to clarify, there is no list or any include in my statsscreenlayout.

Any tips? Thanks

You cannot inflate views directly as a list. I think you can search the ListView methods addHeaderView or addFooterView . Be sure to call them before calling setListAdapter .

EDIT: fully state this. Suppose you wanted statsviewlayout at the top of the list: Do not put LinearLayout directly on the ListView element ( ListViews should not have children). Put it in a separate XML file (say statsview.xml ) and do something similar in your onCreate:

 getListView().addHeaderView(View.inflate(this, R.layout.statsview.xml, null));
