Android checkbox dialog (easy)

I have a dialog with checkboxes, and I was trying to do different things when options are selected and when OK is pressed.

I thought I knew what I was doing after reading some tutorials, but when I press OK it just toasts "Everything" even if it isn't checked. So it seems that my if statements are not working correctly, but I don't know why.

What am I doing wrong and how do I fix it?

    final CharSequence[] items = {"Item 1", "Item 2", "Item 3"};
    final boolean[] states = {false, false, false};
    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setTitle("What would you like to do?");

    builder.setMultiChoiceItems(items, states, new DialogInterface.OnMultiChoiceClickListener(){
        public void onClick(DialogInterface dialogInterface, int item, boolean state) {
        }
    });

    builder.setPositiveButton("Okay", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int id) {
            SparseBooleanArray CheCked = ((AlertDialog)dialog).getListView().getCheckedItemPositions();
            if(CheCked.get(CheCked.keyAt(0)) == true){
                Toast.makeText(Backup.this, "Item 1", Toast.LENGTH_SHORT).show();
            }
            if(CheCked.get(CheCked.keyAt(1)) == true){
                Toast.makeText(Backup.this, "Item 2", Toast.LENGTH_SHORT).show();
            }
            if(CheCked.get(CheCked.keyAt(2)) == true){
                Toast.makeText(Backup.this, "Item 3", Toast.LENGTH_SHORT).show();
            }
        }
    });

    builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int id) {
             dialog.cancel();
        }
    });

    builder.create().show();
}
