Unable to check/uncheck CheckedTextView inside getView

I'm loading phone contacts in a custom ListView. Each row is a checkable LinearLayout containing a CheckedTextView and another TextView.

I'm feeding the list view with a custom ArrayAdapter. My problem is that I can't control CheckedTextViews inside getView(). For example when I try the following

public View getView(int position, View convertView, ViewGroup parent) {
        View row = convertView;
        if(row == null){            
            row = inflater.inflate(layout, parent, false);
        }

        CheckedTextView checkedTextView =  (CheckedTextView) row.findViewById(R.id.checkedTextView);
        checkedTextView.setText("A");
        checkedTextView.setChecked(true);
        return row;
    }

That's supposed to check every text view whenever I scroll the list view, but that's not happening. Can anybody tell me how to do it?

EDIT: It's important to check it inside getView(), I can't just check all after setListAdapter()

EDIT2: This is the xml file showing the view of each row

<?xml version="1.0" encoding="utf-8"?>
<com.example.multiplecontacts.CheckableLinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <CheckedTextView
        android:id="@+id/checkedTextView"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:checkMark="?android:attr/listChoiceIndicatorMultiple"
        android:paddingBottom="0dp"
        android:text="CheckedTextView"
        android:textAppearance="?android:attr/textAppearanceLarge" />

    <TextView
        android:id="@+id/subTextView"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="Small Text"
        android:paddingTop="0dp"
        android:textAppearance="?android:attr/textAppearanceSmall" />

</com.example.multiplecontacts.CheckableLinearLayout>

CheckableLinearLayout is a custom layout that extends LinearLayout and implements Checkable as I said before. And I've taken it from here

Did you set a checkMark property for your CheckedTextView in your layout xml?

For example: android:checkMark="?android:attr/listChoiceIndicatorMultiple

CheckedTextView is not just a checkbox with a text. You must also note, that CheckedTextView is not focusable, or clickable without some manipulation (since it was designed for ListView and therefore it's state must be controlled by ListView's setOnItemClickListener)

setChoiceMode should be set for a ListView. And checking of the row inside adapter's getView should be done via: listView.setItemChecked(position, value)

@Pier-Luc Gendreau and @fox mentioned the solution in comments but not in answer, so posting answer on their behalf.

As mentioned by @AlexOrlov, CheckedTextView is not focusable, or clickable without some manipulation. So what you have to do is set item check using ListView, you can either do it from the adapter itself or from activity/fragment where you have ListView.

To do it from adapter,

public View getView(int position, View convertView, ViewGroup parent) 
{ 
if (//logic) {
((ListView) parent).setItemChecked(position, true);
}
}

From activity/fragment

if (//logic) {
listView.setItemChecked(position, true);
}
