may help you . Use the SubItems property of each ListViewItem in the ListView. Note that the first entry in the SubItems collection is the main ListViewItem text:
code :
    Using SW As New System.IO.StreamWriter("someFile.txt")
        Dim line As String
        Dim values As New List(Of String)
        For Each LVI As ListViewItem In ListView1.Items
            values.Clear()
            For i As Integer = 0 To LVI.SubItems.Count - 1
                values.Add(LVI.SubItems(i).Text)
            Next
            line = String.Join(",", values.ToArray)
            SW.WriteLine(line)
        Next
    End Using

This might help you Hi again i was able to successfully deleted items in the my listbox which is not yet check-out but when i was updating my database using the remaining items in the listview it yields infinite loop. the problem is at the line where i update the remaining in my listview it only updates the first line and do not loop on the next line. , this line is suspicious, just try to remove it :
code :
i = i - 1
For i As Integer = 0 To 100
    i = i - 1
Next
Console.WriteLine("Finish loop")

fixed the issue. Will look into that further You need 3 things:
a single row layout a class to store your App-Name & Icon a custom list adapter
code :
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="60dp"
android:background="@drawable/nav_item_bg"
android:clickable="true"
android:orientation="horizontal">

<ImageView
    android:id="@+id/icon"
    android:layout_width="30dp"
    android:layout_height="30dp"
    android:layout_gravity="center_vertical"
    android:layout_marginLeft="16dp" />

<TextView
    android:id="@+id/text"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerVertical="true"
    android:layout_gravity="center_vertical"
    android:layout_marginLeft="16dp"
    android:textSize="16sp" />

</LinearLayout>
public class AppDetails {
    String name;
    Drawable icon;

    public AppDetails(String name, Drawable icon) {
        this.name = name;
        this.icon = icon;
    }
}
public class AppDetailsAdapter extends BaseAdapter {

private ArrayList<AppDetails> data;
private Context context;

public AppDetailsAdapter(Context context, List<AppDetails> data){
    this.context = context;
    this.data = data;
}

@Override
public int getCount(){
    return data.size();
}

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

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

@Override
public View getView(int position, View convertView, ViewGroup parent){
    View view = convertView;

    if(view == null){
        LayoutInflater vi = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        view = vi.inflate(R.layout.custom_row_layout, null);
    }

    ImageView icon = (ImageView) view.findViewById(R.id.icon);
    TextView text = (TextView) view.findViewById(R.id.text);

    final AppDetails item = data.get(position);
    text.setText(item.name); 
    icon.setImageDrawable(item.icon);

    return view;
}
List<AppDetails> appList = new ArrayList<>();
for (Object object : pkgAppsList)
{
    //This is your foreach loop over all apps
    //.. Add these 2 line at the end of your loop
    AppDetails tmp = new AppDetails(strAppName, icon);
    appList.add(tmp)
}
ListView listview = (ListView) findViewById(R.id.listView);
AppDetailsAdapter adapter = new AppDetailsAdapter(this, appList);
listview.setAdapter(adapter);

I hope this helps you . ListViewItem class has a lot of constructors. The most appropriate for your case is ListViewItem Constructor (String[])
code :
Products.Items.AddRange(basket.ProductList.Select(p => new ListViewItem(new string[]
{ 
    p.Description,
    p.Quantity.ToString(...),
    p.UnitPrice.ToString(...),
     ...  
})).ToArray());

To fix this issue I was trying to retrieve the values from ListView items as " mylistview.getItemAtPosition(position).toString()" but its returning only the position of the item I am clicking. , You could try make methods in your adapter, something like this:
code :
public String getName(int position) {
    return name1.get(position);
}

public String getPhoneNumber(int position) {
    return phno1.get(position);
}
