Answer 1

As commented, your adapter_layout does not have a CheckedTextView - checkBox1 is a CheckBox (which is a TextView). You should do this:

<CheckedTextView
    android:id="@+id/checkBox1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:padding="10dp"
    android:layout_marginTop="5dp"
    android:text="CheckBox" />

Also, your activity_main layout does not have a listView1 - but it looks like you may have pasted the same layout twice.
