Java.lang.ClassCastException:android.widget.RelativeLayout cannot is cast to Android.widget.TextView

Recently, when learning Drawerlayout, this bug was encountered. As shown below:

Java.lang.ClassCastException:android.widget.RelativeLayout cannot is cast to Android.widget.TextView

Reason:

The ID of the TextView may not be included in the adapter parameter.

Solution:

The original adapter parameter code

Mdrawerlist.setadapter (New arrayadapter<string> (This,r.layout.list_item,datas));

You can modify it to the following form:

Mdrawerlist.setadapter (New arrayadapter<string> (This,r.layout.list_item,r.id.text_view,datas));
