用来显示物节点进度的自定义View，仿淘宝
先拷贝View包下面的文件到你的项目，记得样式等Attr文件也要复制，不然会报错
在你的XMl文件中：
<com.nodeprogress.nodeprogress.view.NodeProgressView
android:id="@+id/npv_NodeProgressView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:width="2dp"
app:nodeRadius="5dp"
/>
然后第一步，你的物流数据，我们先假设几条，一般要从服务器获取
List<LogisticsData> logisticsDatas;
logisticsDatas = new ArrayList<>();
logisticsDatas.add(new LogisticsData().setTime("2016-6-28 15:13:02").setContext("快件在【相城中转仓】装车,正发往【无锡分拨中心】已签收,签收人是【王漾】,签收网点是【忻州原平】"));
logisticsDatas.add(new LogisticsData().setTime("2016-6-28 15:13:02").setContext("快件在【相城中转仓】装车,正发往【无锡分拨中心】"));
logisticsDatas.add(new LogisticsData().setTime("2016-6-28 15:13:02").setContext("【北京鸿运良乡站】的【010058.269】正在派件"));
logisticsDatas.add(new LogisticsData().setTime("2016-6-28 15:13:02").setContext("快件到达【潍坊市中转部】,上一站是【】"));
logisticsDatas.add(new LogisticsData().setTime("2016-6-28 15:13:02").setContext("快件在【潍坊市中转部】装车,正发往【潍坊奎文代派】"));
logisticsDatas.add(new LogisticsData().setTime("2016-6-28 15:13:02").setContext("快件到达【潍坊】,上一站是【潍坊市中转部】"));
logisticsDatas.add(new LogisticsData().setTime("2016-6-28 15:13:02").setContext("快件在【武汉分拨中心】装车,正发往【晋江分拨中心】"));
logisticsDatas.add(new LogisticsData().setTime("2016-6-28 15:13:02").setContext("【北京鸿运良乡站】的【010058.269】正在派件"));
logisticsDatas.add(new LogisticsData().setTime("2016-6-28 15:13:02").setContext("【北京鸿运良乡站】的【010058.269】正在派件"));
logisticsDatas.add(new LogisticsData().setTime("2016-6-28 15:13:02").setContext("【北京鸿运良乡站】的【010058.269】正在派件"));
logisticsDatas.add(new LogisticsData().setTime("2016-6-28 15:13:02").setContext("【北京鸿运良乡站】的【010058.269】正在派件"));第二，找到你的控件并为其设置NodeProgressAdapter适配器
NodeProgressView nodeProgressView = (NodeProgressView) findViewById(R.id.npv_NodeProgressView);
nodeProgressView.setNodeProgressAdapter(new NodeProgressAdapter() {
@Override
public int getCount() {
return logisticsDatas.size();
}
@Override
public List<LogisticsData> getData() {
return logisticsDatas;
}
});OK，大功告成，剩下的就是交给控件了，有兴趣的童鞋可以看看源码，写的不是很好，多多指教，是不是很简单呢；
下面将源码贴出，大家可以看一看

}值得注意的是使用此控件的童鞋，里面有一个JavaBean需要实现，你也可以继承自此Bean
