Android java.util.HashMap cannot be cast to java.lang.String

Question

public void onItemClick(AdapterView<?> parentAdapter, View view, int position,
                                     long id) {
                TextView clickedView = (TextView) view;
                /* Line 79 */ String selectedRouteName = (String) parentAdapter.getItemAtPosition(position);
                String temp = selectedRouteName.substring(0, 2);

Error shown is:

02-18 01:56:53.676: E/AndroidRuntime(821): java.lang.ClassCastException: java.util.HashMap cannot be cast to java.lang.String
02-18 01:56:53.676: E/AndroidRuntime(821):  at com.coltonnicotera.londontransitguide.SchedulesActivity$1.onItemClick(SchedulesActivity.java:79)

Not sure what is causing this, I found java.lang.String cannot be cast to java.util.HashMap exception and it seems that I'm doing everything right.

There is not enough info for us to help. Please provide the code of the adapter. — Wenhui

Why would you think that you COULD cast a HashMap to a String??? — Hot Licks

It means that parentAdapter.getItemAtPosition(position) is returning a HashMap instance, which you're trying to convert to a string with the line

String selectedRouteName = (String) parentAdapter.getItemAtPosition(position);

You should check the content of that AdaptaverView.

Please compare the java with real life, you are trying to convert DOG object into Peacock object , that is not possible.

And you should use toString() method of object class for string conversion.
