我嘗試與第一用戶答案，我得到這個異常：12-14 22:39:56.191: ERROR/AndroidRuntime(917): java.lang.IllegalStateException: ArrayAdapter requires the resource ID to be a TextView

這是XML項目我做的代碼：

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" > 
     <TextView 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:text="Left side" 
     android:layout_alignParentLeft="true"/> 
     <TextView 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:text="Right side" 
     android:layout_alignParentRight="true"/> 
</RelativeLayout> 

這是代碼，我有我的清單：

public class PendingInvitations extends ListActivity { 

...... 
..... 
....  
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
    private List<String> usernames=new ArrayList<String>(); 
     for (int i=0;i<friends.size();i++) 
       { 
       usernames.add(i,friends.get(i).getFullName()); 
       } 


       setListAdapter(new ArrayAdapter<String>(this, R.layout.list_item2, usernames));

這將是用於每個細胞

<?xml version="1.0" encoding="utf-8"?> 
    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content" > 
     <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Left side" android:layout_alignParentLeft="true"/> 
     <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Right side" android:layout_alignParentRight="true"/> 
    </RelativeLayout> 

這個觀點是一個例子，因爲我不知道在哪裏你的知識是在與列表，如果上面的XML被稱爲「temp.xml」你會在setlistadapter功能

import android.app.ListActivity; 
    import android.os.Bundle; 
    import android.widget.ArrayAdapter; 

    public class FooList extends ListActivity extends BaseAdapter { 
     String[] listItems = {"item 1", "item 2 ", "list", "android", "item 3", "foobar", "bar", }; 
     @Override 
     public void onCreate(Bundle savedInstanceState) { 
      super.onCreate(savedInstanceState); 
      setContentView(R.layout.layout_with_listview); 

      // implement your own adapter 

     } 

    } 
public View getView(int position, View convertView, ViewGroup parent) { 
       // A ViewHolder keeps references to children views to avoid unneccessary calls 
       // to findViewById() on each row. 
       ViewHolder holder; 

       // When convertView is not null, we can reuse it directly, there is no need 
       // to reinflate it. We only inflate a new View when the convertView supplied 
       // by ListView is null. 
       if (convertView == null) { 
        convertView = mInflater.inflate(R.layout.temp, null); 

        // Creates a ViewHolder and store references to the two children views 
        // we want to bind data to. 
        holder = new ViewHolder(); 
        holder.left = (TextView) convertView.findViewById(R.id.left); 
        holder.right = (TextView) convertView.findViewById(R.id.right); 

        convertView.setTag(holder); 
       } else { 
        // Get the ViewHolder back to get fast access to the TextView 
        // and the ImageView. 
        holder = (ViewHolder) convertView.getTag(); 
       } 

       // Bind the data efficiently with the holder. 

       holder.left.setText("left text"); 
       holder.right.setText("right text"); 

       return convertView; 
      } 

    class ViewHolder 
    { 
     public TextView left; 
     public TextView right; 
    }

ListView的每個項目必須是一個視圖。這包括ViewGroups。因此，您可以使用任何佈局來排列ListView項目中的多個視圖。
