How to make a custom view on a multiselect listview. Including a select all checkbox. To use the multiselect your custom view root must implement Checkable. You have to be careful about using the list view to check and uncheck things.

CheckableRelativeLayout

public class checkedLayout extends RelativeLayout implements Checkable {

    public UnpaidItemCheckedLayout(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    boolean isChecked;


    @Override
    public boolean isChecked() {
        return isChecked;
    }

    @Override
    public void setChecked(boolean checked) {
        isChecked = checked;
        CheckBox cb;
        if((cb = (CheckBox)findViewById(R.id.itemCheckbox)) != null) {
            cb.setChecked(checked);
        }
        
    }

    @Override
    public void toggle() {
        setChecked(!isChecked);
        
    }

}

createView

@Override
    public void onViewCreated(View view, Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
        checkAllCheckbox.setChecked(true);
        checkAllCheckbox.setOnClickListener(new OnClickListener(){

            @Override
            public void onClick(View v) {
                //note that the checking action happens before onclick so the isChecked is valid for the state it will be
                if(((CheckBox)v).isChecked()) {
                    for(int i = 0; i < adapter.getCount(); i ++ ) {
                        listView.setItemChecked(i, true);
                    }
                }
                else {
                    for(int i = 0; i < adapter.getCount(); i ++ ) {
                        listView.setItemChecked(i, false);
                    }
                }
                
            }});
        
        adapter = new ArrayAdapter<Visit>(getActivity(),android.R.layout.simple_list_item_multiple_choice){
           
            @Override
            public View getView(int position, View convertView, ViewGroup parent) {
                View newView = convertView;
                if (newView == null) {
                    LayoutInflater li = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                    newView = li.inflate(R.layout.unpaid_item, null);
                }
                ((TextView)newView.findViewById(R.id.NameLabel)).setText(getItem(position).name);
                SimpleDateFormat dateFormat = new SimpleDateFormat("EEE MMM d, yyyy", Locale.US);
                ((TextView)newView.findViewById(R.id.TimeLabel)).setText("on " + dateFormat.format(getItem(position).startDateTime.getTime()));
                
                newView.setOnClickListener(new OnClickListener() {

                    @Override
                    public void onClick(View v) {
                        //toggle, if it is checked uncheck it
                        if(((checkedLayout)v).isChecked()) {
                            listView.setItemChecked((Integer) v.getTag(), false);
                            checkAllCheckbox.setChecked(false);
                        }
                        else{
                            listView.setItemChecked((Integer) v.getTag(), true);
                            if(listView.getCheckedItemCount() == adapter.getCount()) {
                                checkAllCheckbox.setChecked(true);
                            }  
                        }
                    }});
                //set the tag of the position so it can be used in the onclick
                newView.setTag(position);

                return newView;
            }
        };
        listView.setAdapter(adapter);
        listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
    }

//reading the items that are checked
        ArrayList<Item> retVal = new ArrayList<Item>();
        SparseBooleanArray checkedPositions = listView.getCheckedItemPositions();
        for(int i=0; i < adapter.getCount(); i++) {
            if(checkedPositions.get(i, false)) {
                retVal.add(adapter.getItem(i));
            }
        }
