CheckedTextView set to checked oncreate in listview?
I am trying to make a shoppinglist, where the CheckedTextView is checked if you have already picked your item previously ie the item has a boolean set to true if picked.
I have overriden the getview method to change the CheckedTextView text with setText() and that works but setting the setChecked(true) method in CheckedTextView doesnt not make it checked.
I know that I am not recycling any views in getview(), that will be a later project in the project, right know I need to see a green checkmark =)
Any thoughts? please help.
my xml files:
test.xml
<CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/text1"
android:layout_width="fill_parent"
android:layout_height="?android:attr/listPreferredItemHeight"
android:textAppearance="?android:attr/textAppearanceLarge"
android:gravity="center_vertical"
android:checkMark="?android:attr/textCheckMark"
android:paddingLeft="5dip"
android:paddingRight="50dip"
android:textColor="#000000"
android:background="#ffffff"
android:tag="text1"
android:text="testtestetstt"
android:focusable="false"/>

If you are going to use setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
, you need to use the setSelection()
method on ListView
to indicate which get checked, not handle that yourself during row binding.
Look at this post: Android ListView CHOICE_MODE_MULTIPLE, how to set checked index? It sais that the method setItemChecked of ListView should be used to set the preselection.
