copied!<p>Take a look at <a href="http://nickcharlton.net/post/building-custom-android-listviews">this link</a></p> <p>This is the resource I ve read to implement my own custom list view. It was really helpful for me. I think you need to add a checkbox in the list_item.xml file and change the layout attributes. </p> <p>You should also need to add a listener to the CheckBox object onCheckedChanged inside custom adapter. </p> <p>Here is a sample code of mine for a custom adapter;</p> <pre><code>public class EntryAdapter extends ArrayAdapter<Entry> { private Activity context; private LayoutInflater inflater; private ArrayList<Entry> entries; public EntryAdapter(Activity context, ArrayList<Entry> objects) { super(context, R.layout.entry_item, objects); // TODO Auto-generated constructor stub this.context = context; this.entries = objects; } public View getView (int position, View convertView, ViewGroup parent) { View viewRow = convertView; if(viewRow == null) { inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); viewRow = inflater.inflate(R.layout.entry_item , null, true); } Entry e = entries.get(position); if(e != null) { TextView aka = (TextView) viewRow.findViewById(R.id.authorTextView); TextView content = (TextView) viewRow.findViewById(R.id.entryContentTextView); if(aka != null && content != null){ aka.setText(e.getAka()); content.setText(e.getContent()); } } return viewRow; } </code></pre> <p>}</p> <p>In this code, there is no event listeners. What you should firstly do is to add is define an arraylist of boolean like </p> <pre><code>ArrayList<boolean> selectedItems; </code></pre> <p>after that, inside the getView method you should add the following;</p> <pre><code>CheckBox cb = (CheckBox) findViewById(R.id.checkBoxId); </code></pre> <p>after that, you should add onCheckStateChanged listener inside the getView() method</p> <pre><code>cb.setOnCheckedChangeListener(new OnCheckedChangeListener() { public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { if ( isChecked ) { // find out the item is selected or not and add to selected arraylist by using the position of the element } } }); </code></pre> <p>and lastly, you should have getSelectedMethod that returns the arraylist of selected items with respect to their positions.</p> <p>Hope I understand the question and it will be helpful for you.</p>
