Apps ListView not displaying anything.

[abcd2000]

I am trying to display a text and an icon in a ListView. Below is my code. When I run, I am not getting anything displayed in simulator. Can somebody please look at the code below and tell me what is wrong?

I tried to make this code as suggested in thread http://androidforums.com/application-development/412041-help-required-create-listview.html

 listview.xml:
 ------------------------------------------------------
 <?xml version="1.0" encoding="utf-8"?>
 <ListView android:id="@android:id/list"
       xmlns:android="http://schemas.android.com/apk/res/android"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content">
       <TextView
             android:id="@+id/textView" 
             android:padding="3dip"
             android:layout_width="wrap_content"
             android:layout_height="wrap_content" />
         <ImageView 
             android:id="@+id/imageView" 
             android:layout_width="wrap_content"
             android:layout_height="wrap_content"
             android:gravity="right"/>
 </ListView>

         super.onCreate(savedInstanceState);
         //setContentView(R.layout.listview);
         FileAdapter adapter = new FileAdapter(this);
         adapter.addFile(new FileView(this, null, "One", R.drawable.folder));

Found the issue. I forgot to add the image and text to the FileView in its constructor.

public FileView(Context context, File file, CharSequence lable, int resId) {
        super(context);
        this.file = file;
        text = new TextView(context);
        text.setText(lable);
        image = new ImageView(context);
        this.resId = resId;
        image.setImageResource(resId);
        addView(image);
        addView(text);
    }
