NodeProgressView

用来显示物节点进度的自定义View，仿淘宝

版本尚未发布到Jcenter，后续将会逐一发布，让你使用更简洁

使用

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

        final float scale = context.getResources().getDisplayMetrics().density;
        return (int) (dpValue * scale + 0.5f);
    }

}

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
