I have really tried hard for a week trying to figure out how to make multiline text in a listview. but i simply cant figure out what i am doing wrong.

tells me i need a listview named android.R.id.list but i can find anywhere in the code where i have referred to such a list.

anyone who can help would be appreciated.

Ty for your time and best regards,
Mark


i have created a list view

Java Code:
<ListView
        android:id="@+id/listview2"
        android:layout_width="fill_parent"
        android:layout_height="match_parent"
        android:layout_above="@+id/AddsBannerHere"
        android:layout_alignParentLeft="true"
        android:layout_below="@+id/NameOfList"
        android:layout_toLeftOf="@+id/NameOfItem"
        android:layout_marginLeft="5dp" >

        
    </ListView>
and made a textview to put in the text

Java Code:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >
    <TextView 
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/line_a"/>
    
    <TextView 
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/line_b"/>
    
    <TextView 
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/line_c"/>
    </LinearLayout>
and wrote this for class

Java Code:
public class CreateFirst extends ListActivity {
	
	private AdView adView;
	private SimpleAdapter sa;
	ArrayList<HashMap<String,String>> list = new ArrayList<HashMap<String,String>>();

public void Add_New_Item() {
    	
    	HashMap<String,String> item;
    	
    	EditText nameofitem = (EditText) findViewById(R.id.NameOfItem);
    	String stringnameofitem = nameofitem.getText().toString();
    	
    	item = new HashMap<String,String>();
    	item.put("line1", stringnameofitem);
    	
    	EditText nrofitem = (EditText) findViewById(R.id.NrOfItem);
    	EditText weightofitem = (EditText) findViewById(R.id.Weight_Liter);
    	String stringnrofitem = nrofitem.getText().toString() + " " + weightofitem.getText().toString();
    	item.put("line2", stringnrofitem);
    	
    	EditText valueofitem = (EditText) findViewById(R.id.Value_Of_Item);
    	String stringvalueofitem = valueofitem.getText().toString();
    	item.put("line3", stringvalueofitem);
    	list.add( item );
    	
    	sa = new SimpleAdapter(this, list, 
    			R.layout.activity_multi_lines, 
    			new String[] {"line1", "line2","line3"}, 
    			new int[]{R.id.line_a, R.id.line_b, R.id.line_c});
    	
    	setListAdapter(sa);
    }

when i try to open the activity i get
