In which file do you have:
android:onClick="viewOfferingDetails"
Maybeok 14-Apr-18 2:50am    
It is in offering_list_item.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:onClick="viewOfferingDetails"
android:clickable="true"
android:id="@+id/offeringListLinearLayout">

<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">

<TextView
android:text="TextView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textSize="20sp"
android:id="@+id/offeringListFullNameTextView" />






1 solution

The exception is clear enough. You have defined onClick in xml layout, but you not adding that method in your activity class. It should have something like this in your activity class.
public void viewOfferingDetails(View view) {
       .....
    });

From the error you post earlier, it looked like you have defined viewOfferingDetails in xml layout, but I didn't see that. Have you changed something in layout ?

no i have not changed anything
