Cannot be cast to Android. widget. headerviewlistadapter

This exception usually occurs when header or footerview is set with listview.

If you didn't happen, it would happen. But you may not know the reason.

If the header or tail view is added after the listview. setadapter (adapter) method,

That is, addheaderview or addfooterview,

This exception is reported when listview. removehearderview or removefooterview is used.

If an adapter is set in the source code of listview, it is converted to headerviewlistadapter, so an error is reported.

If (madapter! = NULL & (headerviewlistadapter) madapter). removeheader (V )){
If (mdatasetobserver! = NULL ){
Mdatasetobserver. onchanged ();
}
Result = true;
}

.

Therefore, you must call addheaderview or addfooterveiw before setadapter.
