< RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/redbg"> 
    < ListView
        android:layout_marginTop="100dp"
        android:id="@+id/list"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
     />

    public CustomListViewAdapter(Context context, String[] values)
       {
        super(context, R.layout.list_view, values);
        this.context = context;
        this.values = values;
       }
    @Override
    public View getView(int position, View convertView, ViewGroup parent) 

     {
        LayoutInflater inflater = (LayoutInflater) context   
                                          .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View rowView = inflater.inflate(R.layout.list_view, parent, false);

        ImageView imageView = (ImageView) rowView.findViewById(R.id.icon);
        textView.setText(values[position]);
        // Change icon based on name
        String s = values[position];
        System.out.println(s);
