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

Answer Source

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)
