I have a list view that is populated with check boxes. The text on each box is set with the `ListAdapter`. When everything loads up I need a few of the check boxes to be checked by default and some of them to not be checked. I am able to call `setChecked` on the check boxes but it is not working. I believe this is because in the `onCreate()` the view is not visible yet. So I moved it to `onResume()` and `onCreate()` and so far it still does not work. It seems that they are still not yet loaded and on the screen yet.

```
private void markAllTags()//this will put a check mark on the ones that are already a tag of that question
{
    String tags[] = mUserDb.fetchTagById(mQid);//These are the tags that are already associated with this question
    for(int i = 0; i < this.getListAdapter().getCount(); i++)
    {
        View v = this.getListAdapter().getView(i, null, null);
        //Log.w("NME", "I = " + this.getListAdapter().getView(i, null, null).findViewById(R.id.checkBox1));
        if(v != null)
        {
            CheckBox cb = (CheckBox)v.findViewById(R.id.checkBox1);
            String cbTags = "" + cb.getText();
            for(int j = 0; j < tags.length; j++)
            {
                //Log.w("NME", "cbTag = " + cbTags + " tags[j] = " + tags[j]);
                if(cbTags.equals(tags[j]))
                {
                    cb.setChecked(true);
                }
            }
        }

    }
}

```

This is currently being called from onStart. 

If I use `listview.getchildAt()` I receive a null value. 

EDIT: There is no crash so nothing really coming up in logcat. So the problem is that when the final if statement is met it doesn't mark it as checked. 

EDIT 2: So I have tried a few more things. I linked the function above to a button and it still did not work. When I changed the line where `View v` is set. To this `View v = mListView.getChildAt(i);` It worked when I pressed the button. However it still does not work when the activity starts. The problem is now that v is null.
