This Article shows to create SimpleAdapter for ListView in Android.

1- Create row xml for ListView(row.xml).

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
     xmlns:android="http://schemas.android.com/apk/res/android"
     android:layout_width="fill_parent"
     android:layout_height="wrap_content"
     android:orientation="vertical">
     <TextView android:id="@+id/text1"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"/>
     <TextView android:id="@+id/text2"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:layout_weight="1"/>
     <TextView android:id="@+id/text3"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:layout_weight="1"/>
</LinearLayout>

2- Create ListActivity(MainActivity.java).

import java.util.ArrayList;

import java.util.HashMap;

import android.app.ListActivity;

import android.os.Bundle;

import android.widget.SimpleAdapter;

public class Abc extends ListActivity { 

@Override

protected void onCreate(Bundle savedInstanceState) {

// TODO Auto-generated method stub

super.onCreate(savedInstanceState);

ArrayList<HashMap<String, String>> list =

                  new ArrayList<HashMap<String, String>>();

String[] from = new String[] {"Text1", "Text2", "Text3"};

int[] to = new int[] {R.id.text1, R.id.text2, R.id.text3};

for(int i=0; i<3; i++) {

HashMap<String,String> map = new HashMap<String, String>();

//initialize row data

map.put(from[i], "Text" + i);

list.add(map);

}

setListAdapter(new SimpleAdapter(this, list, R.layout.row, from, to));

}

}
