Apps Help required to create a ListView

thanks

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 loot at the code below and tell me what is wrong?

I tried to make this code as suggested above.
------------------------------------------------------
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"
androidadding="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>

FileActivity.java:
------------------------------------------------------
package com.vsb.file;

import android.app.ListActivity;
import android.os.Bundle;

public class FileActivity extends ListActivity {

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.listview);
FileAdapter adapter = new FileAdapter(this);
adapter.addFile(new FileView(this, null, "One", R.drawable.folder));
adapter.addFile(new FileView(this, null, "Two", R.drawable.file));
setListAdapter(adapter);
}
}

------------------------------------------------------
FileView.java:

package com.vsb.file;

import android.widget.TextView;

public class FileView extends LinearLayout {

private File file;
private ImageView image;
private TextView text;
private int resId;

public File getFile() {
return file;
}

public void setFile(File file) {
this.file = file;
}

public ImageView getImage() {
return image;
}

public void setImage(int resId) {
this.image.setImageResource(resId);
this.resId = resId;
}

public TextView getText() {
return text;
}

public void setText(CharSequence text) {
this.text.setText(text);
}

public FileView(Context context) {
super(context);
}

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

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

this.resId = resId;
image.setImageResource(resId);
}

public int getResId() {
return resId;
}

public void setResId(int resId) {
this.resId = resId;
}

}

}

public void addFile(FileView fv) {

@Override
