Question

I have a custom listView in my app I would like to implement my select all button I have created.

My ListView looks like.

[(Image)(Text)(CheckBox)]

I have looked at some similar questions, the most common answer was with the user of the notifyDataSetChanged () method, iv’e tried researching and implementing without any luck, I was wondering can you think of a way round it or give me an example of how I can implement the method

Answer 1

I couldn’t get the above answer to work, so I used parts of another answer and found the answer.

I added this this globally.

ListView list;
//\\ 0 = None set \\// 1 = Select all \\// 2 = Un-Select all//\\
int selState = 0;

Then in the onClick method I used

        selState = 2;
        list.invalidateViews();

selState being equal to what function you want to do

In the Adapter, this is final part of code

switch(selState)
   {
   ...     
   case 2:
       CheckBox.setChecked(false);
       break;      
   }
