Android逐条加载ListView，实现动画更新

配置文件：

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

程序：
