I have an issue with the basic structure that I can't seem to get past. I am using Eclipse and trying to run through the examples in chapter 4. Here is my issue:

I have a project i setup in Eclipse. Under it have have the usual default setup. I compile and run the default code just fine. When I try to edit the TodoListItemView source file I get an error in the AndroidManifest.xml file in the project root. Here is that file and the <X> in the code below is the issue. The error message is "TDLIV.com.TodoListItemView does not extend android.app.Activity"

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="(deleted the http)schemas.android.com/apk/res/android"
      package="TDLIV.com"
      android:versionCode="1"
      android:versionName="1.0.0">
    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".TodoListItemView"
<X> android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
</manifest>

So far, I am trying to do step #1 on page 83. That code is as follows and shows no errors.
--------------------------
package TDLIV.com;

import android.content.Context;
import android.content.res.Resources;
import android.graphics.Canvas;
import android.graphics.Paint;
import android.util.AttributeSet;
import android.widget.TextView;
import android.app.Activity;
import android.os.Bundle;

public class TodoListItemView extends TextView {

      /** Constructors. Each should call init() */
      public TodoListItemView (Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        init();
      }

      public TodoListItemView (Context context) {
        super(context);
        init();
      }

      public TodoListItemView (Context context, AttributeSet attrs) {
        super(context, attrs);
        init();
      }

      private void init() {
      }

}

I am obviously a novice and would really appreciate anyones comments greatly. I used to do some java coding for fun but was not using Eclipse.

Thanks in advance for any help.

  It looks like the error your seeing in the Chapter 4 example is because the class you've created in step 1 (TodoListItemView) is not an Activity, so you can't put it directly into the Manifest as you've done. It needs to be referenced by a Layout that's in turn used by an ArrayAdapter within an Activity -- that's what's shown in steps 5 and 6.

  What might have caused the confusion is that the example you're looking at in Chapter 4 builds on an earlier example -- the To-do List example in Chapter 2 (page 37). To do the steps in the Chapter 4 example you need to have created that earlier TodoList Activity. The example in Chapter 4 lets you change the appearance of each of the to-do list Items shown in the ListView.

  From the looks of things, I'd say you can probably skip straight to step 5 on page 39 of the Chapter 2 example. Steps 5 through 8 show how to create the Activity layout and the Activity class that you need for Chapter 4. Alternatively, if you want to skip Chapter 2 entirely, you can download the source code for it from here:

http://www.wrox.com/WileyCDA/WroxTit...-DOWNLOAD.html

...and jump straight into the Chapter 4 example.

Let me know how you get on, hopefully I'll be able to help.

Thanks for the help. Of course, I see that now. I'll move on and give it another try.
