How do I create a ListView with rounded corners in Android?

to make border u have to make another xml file with property of solid and corners in the drawable folder and calls it in background

There are different ways to achieve it. The latest approach is using CardView for each ListItem component. Here are some steps.

1. Create a layout resource file; let's name it "listitem.xml
2. Copy and paste the under enclosed Listitem.xml layout body into it.
3. Create RowItem class for each listitem data; later you will instantiate this to assign values for each list item. Check Code below, RowItem.class.
4. Create a custom ListAdapter; let's name it ListAdapter.class, and inflate this (#1) list item layout for each list item (Check the second code snippet for this one)
5. Set this adapter (#3) the way you set default adapters inside an activity the listview belongs to. maybe the only difference would be you first have to instantiate RowItem class with values and add RowItem object to your adapter then notify your adapter that the data is changed.

**listitem.xml**

RowItem.Class

public class RowItem {
    private String heading;
    private String subHeading;
    private int smallImageName;
    private String datetime;
    private int count;

    public void setHeading( String theHeading ) {
        this.heading = theHeading;
    }

    public String getHeading() {
        return this.heading;
    }
    public void setSubHeading( String theSubHeading ) {

        this.subHeading = theSubHeading;

    }

    public String getSubHeading( ) {

        return this.subHeading;

    }

    public void setSmallImageName(int smallName) {

        this.smallImageName = smallName;

    }

    public int getSmallImageName() {

        return this.smallImageName;

    }

    public void setDate(String datetime) {
        this.datetime = datetime;
    }

    public String getDate() {
        return this.datetime;
    }

    public void setCount(int count) {
        this.count = count;
    }

    public int getCount() {
        return this.count;
    }

}

Sample ListAdapter

public class ListAdapter extends BaseAdapter {
    private ArrayList<RowItem> singleRow;
    private LayoutInflater thisInflater;

    public ListAdapter(Context context, ArrayList<RowItem> aRow){

        this.singleRow = aRow;
        thisInflater = ( LayoutInflater.from(context) );
    }
    @Override
    public int getCount() {
        return singleRow.size();    }

    @Override
    public Object getItem(int position) {
        return singleRow.get( position );    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    public View getView(int position, View view, ViewGroup parent) {

        if (view == null) {
            view = thisInflater.inflate( R.layout.mylist2, parent, false );
            //set listview objects here
            //example

            TextView titleText = (TextView) view.findViewById(R.id.titleoflistview);
           
            RowItem currentRow = (RowItem) getItem(position);
            
            titleText.setText( currentRow.getHeading() );
          
        }

        return view;

//        LayoutInflater inflater=.getLayoutInflater();
//        View rowView=inflater.inflate(R.layout.mylist, null,true);
//

//        titleText.setText(maintitle[position]);
//        subtitleText.setText(subtitle[position]);

//        return null;

    };
