HoloEverywhere AutoCompleteTextView java.lang.ClassCastException - autocompletetextview

Question

I am trying to get the HoloEverywhere class AutoCompleteTextView to work with my app. The main reason for this is I want the Holo theme to work on pre 3.0 devices (specifically API levels 8-10) Here is my main activity code:
package com.example.testautocomp;
import org.holoeverywhere.widget.AutoCompleteTextView;
import android.app.Activity;
import android.os.Bundle;
import android.widget.ArrayAdapter;
public class MainActivity extends Activity {
private AutoCompleteTextView m_edit;
private static final String[] items = { "lorem", "ipsum", "dolor", "sit",
"amet", "consectetuer", "adipiscing", "elit", "morbi", "vel",
"augue", "purus", "sitter", "sitting", "sither", "sithar" };
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
m_edit = (AutoCompleteTextView)findViewById(R.id.edit2);
m_edit.setAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_dropdown_item_1line, items));
}
}
also my activity_main.xml code:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<AutoCompleteTextView
android:id="#+id/edit2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:completionThreshold="1"
android:hint="Testing" />
</LinearLayout>
When I run my app, it goes into the debugger for eclipse and after pressing resume (or F8) to continue the thread, my app crashes/force closes and I get the following error in my LogCat:

How do i fix this CastClassException?

Answer 1

No, your action above incorrect. You should change activity base class on org.holoeverywhere.app.Activity.

Answer 2

Very similar to this question
Fixed it by changing my main_activity.xml to:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<org.holoeverywhere.widget.AutoCompleteTextView
android:id="#+id/edit2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:completionThreshold="1"
android:hint="Testing" />
</LinearLayout>
the main part being org.holoeverywhere.widget.AutoCompleteTextView
