android custom TextView in ListView

I created a regular list view with custom adapter and all is well. It is showing the name of the object (exactly what I want). I also want to show couple of other information. So from my research, I found out that I will need to create a custom text view to handle the requirement. I tried doing a basic one where I change the background color to anything other than black, but not working. I really don't know why. Here is the code for custom adapter:

@Override
public View getView(int arg0, View arg1, ViewGroup arg2) {
    // TODO Auto-generated method stub
    if(arg1==null)
        arg1 = layoutInflator.inflate(R.layout.simplerow ,arg2, false);
    TextView name = (TextView)arg1.findViewById(android.R.id.text1);
    name.setText(discountObjectArray[arg0].name);
    return arg1;
}

and here is the code in simplerow.xml for the simple custom textview:

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
 android:id="@+id/customTextView" 
 android:layout_width="fill_parent" 
 android:layout_height="wrap_content"
 android:padding="10dp"
 android:textSize="16sp" 
android:textDirection="rtl"
android:background="@color/thankYouLabelColor">
</TextView>

with simple change of android.R.layout.simple_list_item_1 to R.layout.simplerow the logcat shows error in line 49 which is:

name.setText(discountObjectArray[arg0].name);

Any idea why this would not work?

From this change android.R.id.text1 to R.id.customTextView

TextView name = (TextView)arg1.findViewById(android.R.id.text1);

that is...

TextView name = (TextView)arg1.findViewById(R.id.customTextView);

You have this

      android:id="@+id/customTextView"

Replace this

     TextView name = (TextView)arg1.findViewById(android.R.id.text1);

by

     TextView name = (TextView)arg1.findViewById(R.id.customTextView);

Here's the list of R.id from the the android package

http://developer.android.com/reference/android/R.id.html

You are referring to the one in the android package android.R.id.text1 while you have in xml id of textview as customTextView.

Look at the id attribute here

The problem is you need to change the id of the Textview, so change: 

TextView name = (TextView)arg1.findViewById(android.R.id.text1);

with:

TextView name = (TextView)arg1.findViewById(R.id.customTextView);
