I am trying to populate a listview in which the rows contain a checkbox, four textviews, and two spinners. The values in the spinners on each row need to be different as they directly relate to the actual item on that row. Just to make it that little bit more complicated the spinners and the two text fields beside them are not visible (setVisibility(View.GONE)) unless the checkbox is checked. I just want the list item click-able (not the checkbox), and the spinners need to be click-able once they are shown.
All of my code is working correctly except that when the spinners are populated then I lose the ability to click the list item on that row. I can still choose values from the spinners on that row but touching anywhere else on the row does nothing at all. There are some rows that don’t return data to the spinners and they continue to operate correctly so I believe it is something to do with the adaptors connected to the spinners.
Also I know I will have to account for the list view recycling but I haven’t got that far yet.
I hope someone can point out what is wrong here before I go completely insane.
Here is the listview xml
<ListView android:id="@+id/android:list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
<TextView android:id="@+id/android:empty"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/empty"/>
</LinearLayout>
And here is the row xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<CheckBox android:id="@+id/pl_selected"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:focusableInTouchMode="false"
android:clickable="false"
android:focusable="false"
android:layout_weight="1"/>
<TextView android:id="@+id/name"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:focusableInTouchMode="false"
android:clickable="false"
android:focusable="false"/>
<TextView android:id="@+id/name2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:focusableInTouchMode="false"
android:clickable="false"
android:focusable="false"/>
</LinearLayout>
<LinearLayout android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TextView android:id="@+id/pl_tv1"
android:text="@string/pl_tv1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:focusableInTouchMode="false"
android:clickable="false"
android:focusable="false"
android:visibility="gone"/>
<Spinner android:id="@+id/pl_spin1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:visibility="gone"
android:focusableInTouchMode="false"
android:focusable="false"/>
</LinearLayout>
<LinearLayout android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TextView android:id="@+id/pl_tv2"
android:text="@string/pl_tv2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:focusableInTouchMode="false"
android:clickable="false"
android:focusable="false"
android:visibility="gone"/>
<Spinner android:id="@+id/pl_spin2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:visibility="gone"
android:focusableInTouchMode="false"
android:focusable="false"/>
</LinearLayout>
</LinearLayout>

Thanks in advance for any help you can give.
You can try adding
android:descendantFocussability=blocksDescendantsto the top most linear layout. This might be helpful.
