Get listview item value (specific textview) when deleting

Question

I am creating a CMS application and I want to delete an item, for that I need the ID that I have hidden in the listview item. When I hold a listview item it pops up with a delete button which I click, that brings me to this piece of code:

@Override
public boolean onContextItemSelected(MenuItem item) {
    AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo) item.getMenuInfo();
    switch(item.getItemId()) {
        case R.id.delete:

            new HttpDelete("http://test.soundwave.drieo.nl/api/content/"+ text + apikey);
            return true;
        default:
            return super.onContextItemSelected(item);
    }
}

Custom listview:

When hold clicking on an item this appears wich calls the code. (Verwijderen == delete)

Custom Row XML for custom adapter:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="?android:attr/listPreferredItemHeight"

Try this

public boolean onContextItemSelected(MenuItem item){
    AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo)item.getMenuInfo();

    switch(item.getItemId()) {
    case R.id.delete:    
Toast.makeText(MainActivity.this, ((TextView) info.targetView.findViewById(R.id.tbid)).getText().toString(),Toast.LENGTH_SHORT).show();

    return true;
    default:
        return super.onContextItemSelected(item);
    }
}

you need to get the selected item position (from listview)

public boolean onContextItemSelected(MenuItem item) {
    //...codes 
    AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo();
    int index = info.position;
    //... other codes
}

now use index to get the item from the data set ex, assume data set ArrayList or Array named myItems:

int itemId = myItems.get(index).getId();
//call API using itemId as parameter

Get listview item value (specific textview) when deleting
