NPE when scrolling recyclerview

[jcholin]

I have a NPE when scrolling a recyclerview with ExpandableTextView in items

java.lang.NullPointerException: Attempt to invoke virtual method 'int android.text.Layout.getEllipsisCount(int)' on a null object reference
                                                             at tm.charlie.expandabletextview.ExpandableTextView.updateState(ExpandableTextView.kt:349)

                                                             at android.app.ActivityThread.main(ActivityThread.java:5526)
                                                             at java.lang.reflect.Method.invoke(Native Method)
                                                             at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:726)
                                                             at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:616)

Here the layout of the item:

<tm.charlie.expandabletextview.ExpandableTextView
        android:id="@+id/textview_description"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:etv_animationDuration="200"
        app:etv_collapsedLines="3" />

@arslancharyev31 any idea? The bug appears on a OnePlus X, and Sony Xperia

@jcholin Honestly, haven't tested it with RecyclerView yet. Would you be kind enough to share your recycler view snippet (if possible, with activity) reproducing the NPE? Are you inflating xml from Java? Kotlin?
