Custom List View with text editing and check boxes

I am new to programming and have a problem using getCheckedItemPositions()for checkboxes and getting edit values ​​from edit text in a custom list view. Can someone help me with an example of creating a custom list having the above functionality. Thank you

* This is a custom listview xml

<CheckBox android:id="@+id/checkBox" android:layout_height="wrap_content"
 android:layout_width="wrap_content" 
 android:layout_alignParentRight="true"
 android:text="CheckBox"
 android:onClick="clickHandler"
 ></CheckBox>
<TextView android:layout_height="wrap_content"
 android:layout_width="fill_parent" android:text="TextView" 
 android:id="@+id/textView1" 
 android:layout_alignParentLeft="true"
  android:layout_centerHorizontal="true" android:layout_marginBottom="14dp"

Android: layout_toLeftOf = "@ + id / checkbox">             

* This is the code for setting listview

lv1 = (ListView) dialog.findViewById(R.id.l1);               adapter2 = SimpleCursorAdapter (                           ,                           R.layout.custom,                           CURSOR2,                           new String [] { "ItemName" },                           new int [] {R.id.textView1});

         lv1.setItemsCanFocus(false);
         lv1.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
         lv1.setAdapter(adapter2);

* , ,

public void onClick (View v) {

                int len = lv1.getCount();
                 SparseBooleanArray checked = lv1.getCheckedItemPositions();
                 for (int i = 0 ; i < len; i++)
                  if (checked.get(i)) {
                   String item = mArrayList.get(i);

                mItems.add(mArrayList.get(i));

             System.out.println(item);




                   /* do whatever you want with the checked item */
                  }

        textView_heading.setText(userheading_list.get(position));

        return rowview;

//now the custom list part finish
