    You can use a class inheriting from ArrayAdapter, and overriding its getView() method.

    public class StudentAdapter extends ArrayAdapter<Student> {
    
    protected LayoutInflater inflater;
    
        public StudentAdapter(final Context context) {
            super(context, 0);
            inflater = (LayoutInflater) ((Context) context)
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        }
    
        public View getView(int position, View convertView, ViewGroup parent) {
    
            // Note: You should optimize here with re-using convertView
    
            View rowView = inflater.inflate(R.layout.user_address_row_layout,
                    parent, false);
            TextView sNo = (TextView) rowView.findViewById(R.id.sNo);
            sNo.setText(getItem(position).number);
                // same for every field of the row
                // ...
    
            return rowView;
        }
    
     }

    This is a sample example of custom adapter for listview. Modify it as your need: XML layout :

    <?xml version="1.0" encoding="utf-8"?>
    <LinearLayout android:id="@+id/main"
        android:orientation="vertical"
        android:layout_height="fill_parent"
        android:layout_width="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android">
        <!-- Header -->
    
        <LinearLayout
            android:id="@+id/header"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="@color/black" >
    
            <TextView
                android:id="@+id/item2"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:height="30dip"
                android:text="Latest News - Your Healing Place"
                android:textAppearance="?android:attr/textAppearanceMedium"
                android:textColor="#FFFFFF"
                android:width="100dip" />
    
            <TextView
                android:id="@+id/item1"
                android:layout_width="wrap_content"
                android:layout_height="fill_parent"
                android:height="30dip"
                android:width="20dip" />
    
        </LinearLayout>
    
        <View android:layout_width="fill_parent"
            android:layout_height="1dip"
            android:background="?android:attr/listDivider" />
    
        <LinearLayout android:id="@+id/layout"
            android:layout_width="wrap_content"
            android:layout_height="fill_parent">
    
            <ListView
                android:id="@+id/listview"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                android:background="@color/black" >
    
            </ListView>
    
        </LinearLayout>
    </LinearLayout>
    

    news.java :

    List<HashMap<String, String>> fillMaps = new ArrayList<HashMap<String, String>>();
    String[] from = new String[] {"details", "date"};
    int[] to = new int[] { R.id.item1, R.id.item2};
    ListView lv= (ListView)findViewById(R.id.listview);
    HashMap<String, String> map = new HashMap<String, String>();
    map.put("details", "This is a sample message");
    map.put("date", "24-07-2003");
    fillMaps.add(map);
    
    SimpleAdapter adapter = new SimpleAdapter(this, fillMaps, R.layout.grid_item, from, to);
    lv.setAdapter(adapter);
