Change Text Of Items In Listview When It Is Displayed Using Simplecursoradapter

How to change text of items in ListView when it is displayed using SimpleCursorAdaptor? Here is my code. Cursor allTaskcursor = databaseHelper.getAllTasks(); String[] from = {'name

Solution 1:

If you want to update single list item and you know the index of item, you can call getChildAt(int) on the ListView to get the view and update it like -

TextViewtext2= (TextView) v.findViewById(R.id.text2);
text2.setText("Updated Text");

Or If, you want to update all values in array, you can update the array and call notifyDataSetChanged on adapter to reflect the updated values.

Solution 2:

SimpleCursorAdapter.ViewBinder did the job. As answered here, I changed the code to..

CursorallTaskcursor= databaseHelper.getAllTasks();
    String[] from = {"name", "date"};
    int[] to = newint[] {android.R.id.text1, android.R.id.text2};
    SimpleCursorAdaptercursorAdapter=newSimpleCursorAdapter(context, android.R.layout.simple_list_item_2, allTaskcursor, from, to, CursorAdapter.FLAG_REGISTER_CONTENT_OBSERVER);
    cursorAdapter.setViewBinder(newSimpleCursorAdapter.ViewBinder() {
        @OverridepublicbooleansetViewValue(View view, Cursor cursor, int columnIndex) {
            if (view.getId() == android.R.id.text2) {
                intgetIndex= cursor.getColumnIndex("date");
                intdate= cursor.getInt(getIndex);
                TextViewdateTextView= (TextView) view;
                dateTextView.setText(date + " days");
                returntrue;
            }
            returnfalse;
        }
    });
    allTaskListView.setAdapter(cursorAdapter);
