Create a for loop going through all the child items of the ListView and check if the View is of type CheckBox and perform setChecked(false) on the same.

for (int i = 0; i < mListView.getCount(); i++) { 
       View mChild = mListView.getChildAt(i);

       //Replace R.id.checkbox with the id of CheckBox in your layout
       CheckBox mCheckBox = (CheckBox) mChild.findViewById(R.id.checkbox);
       mCheckBox.setChecked(false);
}
