How to add sticky header in listview with background image on list row in android?

Question

I am trying to add sticky header in listview. I implemented that with the help of code which I found at https://github.com/beworker/pinned-section-listview

Below is the picture in which I got the listview row as

Its working fine but I need to customize above row. there are two separate layout for a single row which are a.) listheader.xml b.) listrow.xml both the xml are two separate parts of a single row of listview.

Now what I want to do is that list row header should be with transparent background(listheader.xml) and listrow.xml should not have the background image of a guy carrying camera. the image should be set to background of each listview row. which will look like below

so my listview row will have a background image and a header not above image but over the image as you can see in the above image. can anybody tell me how can I do that. below is my code of adapter I used.

public abstract class SectionAdapter extends BaseAdapter implements
        OnItemClickListener {

    private int mCount = -1;

    Context context;

    public SectionAdapter(Context c) {
        this.context = c;
        // TODO Auto-generated constructor stub
    }

    public abstract int numberOfSections();

    public abstract int numberOfRows(int section);

    public abstract View getRowView(int section, int row, View convertView,
            ViewGroup parent);

    public abstract Object getRowItem(int section, int row);

    public boolean hasSectionHeaderView(int section) {
        return false;
    }

    public View getSectionHeaderView(int section, View convertView,
            ViewGroup parent) {
        return null;
    }

    public Object getSectionHeaderItem(int section) {
        return null;
    }

    public int getRowViewTypeCount() {
        return 1;
    }

    public int getSectionHeaderViewTypeCount() {
        return 0;
    }

    /**
     * Must return a value between 0 and getRowViewTypeCount() (excluded)
     */
    public int getRowItemViewType(int section, int row) {
        return 0;
    }

     * (excluded, if > 0)
     */

        return 0;
    }

    @Override

            int position, long id) {

Answer 1

I think you need to add another layout file, say listrowitem.xml with RelativeLayout where you will put your listheader.xml on top of listrow.xml. After that, you can make your listheader to have @null background.

Answer 2

Problem

• You want your listheader.xml to be on top of listview
• You want that each item on listView to have its own background

Solution

1. To bring your listheader.xml on top of listView you should do something like this in your main activity XML :

   <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" >
   
   
     <include
       android:id="@+id/listheader"
       android:layout_alignParentTop="true"
       layout="@layout/listheader" />
     . <!-- dont forget your listheader.xml should have transparent background -->
   
     <ListView
       android:id="@+id/yourList"
       android:layout_width="match_parent"
       android:layout_height="match_parent"
       android:layout_alignParentTop="true"
       android:divider="@android:color/transparent" >
     </ListView>
   
   </RelativeLayout>
   

2. To set background to your list view items you should do this:

    public final View getView(int position, View convertView, ViewGroup parent) {
   
   
     /**
      * I didnt have time to study your code about what happens here,
      * but I know the possible solution that you should be implemented here :)
      * Here I will post the code that puts background 
      * to listView row at this position as shown
      * in your image. So here you put your conditions for your 
      * rows that are the same as in the image above that you have shown
      * */
   
       if( /* put the your conditions here so that the row would be the same as in the image */ ){
        LayoutInflater inflater = (LayoutInflater) context.getApplicationContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
       rowView = inflater.inflate(R.layout.listrow, null); // this is your listrow.xml
         // i guess your xml has as root element a relative layout
         RelativeLayout rLayout = (RelativeLayout) rowView .findViewById (R.id.rLayout);
          Resources res = contetx.getResources(); //resource handle
           Drawable drawable = res.getDrawable(R.drawable.newImage);// here you put your image that you want for each row based on your row position or whatever your condition is
   
         rLayout.setBackgroundDrawable(drawable);
       }
   
     }
