Creating Listview using BaseAdapter

Here using List view we can customize List View's as we want by using Base Adapter.Here Base Adapter return one view for each row in getView() method.Main thing about Base Adapter
are following--
1) getView() create a new view when it call first time else it will return an already created view (this is called recycled of view).That's why it make List View scrolling faster

2)getCount() you can limit the number of row by returning a value here

If you want to inflate a complete layout in each row then we have to use LayoutInflatre .I explain here with a layout inflating in each row.So our first step will be to create a layout for row

1).Create one layout for one row

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" >

    <ImageView
        android:id="@+id/icon"
        android:layout_width="22px"
        android:layout_height="22px"
        android:layout_marginLeft="4px"
        android:layout_marginRight="10px"
        android:layout_marginTop="4px"
        android:src="@drawable/ic_launcher" >
    </ImageView>

    <TextView
        android:id="@+id/label"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@+id/label"
        android:textSize="20px" >
    </TextView>

</LinearLayout>

2)Now Create one adapter class

public class MySimpleArrayAdapter extends ArrayAdapter<String> {
 private final Context context;
 private final String[] values;

 public MySimpleArrayAdapter(Context context, String[] values) {
  super(context, R.layout.rowlayout, values);
  this.context = context;
  this.values = values;
 }

 @Override
 public View getView(int position, View convertView, ViewGroup parent) {
  LayoutInflater inflater = (LayoutInflater) context
    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
  View rowView = inflater.inflate(R.layout.rowlayout, parent, false);
  TextView textView = (TextView) rowView.findViewById(R.id.label);
  ImageView imageView = (ImageView) rowView.findViewById(R.id.icon);
  textView.setText(values[position]);
  // Change the icon for Windows and iPhone
  String s = values[position];
  if (s.startsWith("Windows7") || s.startsWith("iPhone")
    || s.startsWith("Solaris")) {
   imageView.setImageResource(R.drawable.no);
  } else {
   imageView.setImageResource(R.drawable.ok);
  }

  return rowView;
 }
}

3)Create one activity class

public class MyListActivity extends ListActivity {
 public void onCreate(Bundle icicle) {
  super.onCreate(icicle);
  String[] values = new String[] { "Android", "iPhone", "WindowsMobile",
    "Blackberry", "WebOS", "Ubuntu", "Windows7", "Max OS X",
    "Linux", "OS/2" };
  MySimpleArrayAdapter adapter = new MySimpleArrayAdapter(this, values);
  setListAdapter(adapter);
 }

}
That will show following design in android

If you want to set onClicklistener to your list view then change your activity class to following

public class MyList extends ListActivity {

 

/** Called when the activity is first created. */
public void onCreate(Bundle icicle) {
  super.onCreate(icicle);
  // Create an array of Strings, that will be put to our ListActivity
  String[] names = new String[] { "Linux", "Windows7", "Eclipse", "Suse",
    "Ubuntu", "Solaris", "Android", "iPhone" };
  ArrayAdapter<String> adapter = new MyPerformanceArrayAdapter(this, names);
  setListAdapter(adapter);
  ListView list = getListView();
  list.setOnItemLongClickListener(new OnItemLongClickListener() {

   @Override
   public boolean onItemLongClick(AdapterView<?> parent, View view,
     int position, long id) {
    Toast.makeText(MyList.this,
      "Item in position " + position + " clicked",
      Toast.LENGTH_LONG).show();
    // Return true to consume the click event. In this case the
    // onListItemClick listener is not called anymore.
    return true;
   }
  });
 }

 @Override
 protected void onListItemClick(ListView l, View v, int position, long id) {
  super.onListItemClick(l, v, position, id);
  // Get the item that was clicked
  Object o = this.getListAdapter().getItem(position);
  String keyword = o.toString();
  Toast.makeText(this, "You selected: " + keyword, Toast.LENGTH_SHORT)
    .show();

 }

}
