<linearlayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="vertical" android:background="@android:color/black">  <linearlayout     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:orientation="horizontal">      <imageview         android:layout_width="40dp"         android:layout_height="40dp"         android:id="@+id/icon"/>      <linearlayout         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:orientation="vertical">          <textview android:id="@+id/line_a"             android:textsize="14dp"             android:textcolor="@android:color/white"             android:layout_width="fill_parent"             android:layout_height="wrap_content"             android:textstyle="bold"/>          <textview android:id="@+id/line_b"             android:textsize="10dp"             android:textcolor="@android:color/darker_gray"             android:layout_width="fill_parent"             android:layout_height="wrap_content"/>      </linearlayout>  </linearlayout> 

java:

    simpleadapter sa;     arraylist<hashmap<string,string>> list = new arraylist<hashmap<string,string>>();     hashmap<string,string> item;      for(int = 0; < j; i++){         item = new hashmap<string,string>();         item.put( "line1", listdata[i][0]);         item.put( "line2", listdata[i][1]);         item.put( "type", listdata[i][2]);         list.add( item );     }      sa = new simpleadapter(this, list,             r.layout.two_lines_list,             new string[] { "line1","line2" },             new int[] {r.id.line_a, r.id.line_b});                          // can add setimageview here? if yes, how?     setlistadapter( sa ); } 

how can make icon image res/drawable... depending on type (listdata[i][2] inserted in hashmap)? eg. if type "1" set icon1.png @ beginning of 2-line-row

you should override simpleadapter.getview(int position, view convertview, viewgroup parent) method, , list item current position(the first param in method), check value set set icon want.

note: you' d better use viewholder pattern in getview method performance.
