Answer 1

You can optimize your code like this :

Replace

if(lv.isItemChecked(0)){
    for(int i = 0; i<=size; i++){
        lv.setItemChecked(i, false);
    }
} else {
    for(int i = 0; i<=size; i++){
        lv.setItemChecked(i, true);
    }
}

by

    boolean check = lv.isItemChecked(0);
    for(int i = 0; i <= size; i++)
        lv.setItemChecked(i, !check);
