A tutorial for creating a Custom ListView can be found here: http://justcallmebrian.com/?p=139

Just need to change the XML layout for each item to have 2 ImageViews like Robby said. Then in your getView of your Adapter (LazyAdapter if you followed along with the other people's answers) you should have something like this:

ImageView image1 = (ImageView) findViewById(R.id.image1); image1.setResource(R.drawable.icon1); ImageView image2 = (ImageView) findViewById(R.id.image2); image2.setResource(R.drawable.icon2); TextView text = (TextView)findViewById(R.id.text); text.setText("I have 2 images");

The tutorial I pasted earlier depicts a way to make the generation of the list dynamic (i.e. not having the resource of R.drawable.icon1/2 and not having the text for your Text images). Something like this may work (assuming you have a Model class that will hold all 3 pieces of information):

int resid1 = context.getResources().getIdentifier("com.domain.sub:drawable/" + myList.get(position).getImage1Name, null, null);
ImageView image1 = (ImageView) findViewById(R.id.image1);
image1.setResource(resid1);
int resid2 = context.getResources().getIdentifier("com.domain.sub:drawable/" + myList.get(position).getImage2Name, null, null);
ImageView image2 = (ImageView) findViewById(R.id.image2);
image2.setResource(resid2);
TextView text = (TextView)findViewById(R.id.text);
text.setText(myList.get(position).getText());

Of course the snippet above assumes you have an ArrayList called myList that also getters to get the image names and the text to display.

You just need to modify the list item layout (in item.xml) to have another ImageView.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" android:layout_height="wrap_content">
    <ImageView android:id="@+id/image1" android:layout_width="50dip" 
        android:layout_height="50dip" android:src="@drawable/stub" 
        android:scaleType="centerCrop" /> 
    <ImageView android:id="@+id/image2" android:layout_width="50dip" 
        android:layout_height="50dip" android:src="@drawable/stub" 
        android:scaleType="centerCrop" /> 
    <TextView android:id="@+id/text" android:layout_width="fill_parent" 
        android:layout_height="wrap_content" android:layout_weight="1" 
        android:layout_gravity="left|center_vertical" android:textSize="20dip" 
        android:layout_marginLeft="10dip" /> 
</LinearLayout>

and modify LazyAdapter's getView() method to add support for the second ImageView.

Here is an example of something similar. You have to create a custom adapter for your ListView.

http://www.softwarepassion.com/android-series-custom-listview-items-and-adapters/

You can probably use most of that example. Just change the row.xml to create tha layout you want and the getView() in the adapter.
