    @Override
    public void onClick(View v) {
        v.setBackgroundDrawable(context.getResources().getDrawable(R.drawable.btn_changecard_changed));
    }
    
}
class ViewHolder{
    public TextView txtCompanyName;
    public Button btnChangeCard;
}

然后是listviewitem的布局文件：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal"
    android:descendantFocusability= "blocksDescendants"
    android:background="@drawable/listview_pressed_bg"
     >

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerVertical="true"
            android:id="@+id/rankinglistitemid"
            android:textColor="@color/black"
            android:textSize="18sp" 
            android:layout_marginLeft="15dip"
            android:layout_marginTop="10dip"
            android:layout_marginBottom="10dip"
            />
        <Button
            android:layout_width="60dip"
            android:layout_height="30dip"
            android:gravity="center"
            android:layout_gravity="center"
            android:layout_centerVertical="true"
            android:id="@+id/rankingchangecardid"
            android:text="@string/exchangecard"
            android:textColor="@color/white"
            android:textSize="14sp"
            android:background="@drawable/changecardbtn_pressed_bg"
            android:focusable = "false"
            android:layout_alignParentRight="true"
            android:layout_marginRight="15dip"
            android:layout_marginTop="10dip"
            android:layout_marginBottom="10dip">
            
        </Button>
</RelativeLayout>

这个布局文件中，

<RelativeLayout>下的

android:descendantFocusability= "blocksDescendants"
和

<Button>下的

android:focusable = "false"可以分离listview和Button的点击事件。
