NodeProgressView

用來顯示物節點進度的自定義View，仿淘寶

版本尚未發佈到Jcenter，後續將會逐一發布，讓你使用更簡潔

使用

先拷貝View包下面的文件到你的項目，記得樣式等Attr文件也要複製，不然會報錯

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"
    />

然後第一步，你的物流數據，我們先假設幾條，一般要從服務器獲取

        List<LogisticsData> logisticsDatas;
        logisticsDatas = new ArrayList<>();
        logisticsDatas.add(new LogisticsData().setTime("2016-6-28 15:13:02").setContext("快件在【相城中轉倉】裝車,正發往【無錫分撥中心】已簽收,簽收人是【王漾】,簽收網點是【忻州原平】"));
        logisticsDatas.add(new LogisticsData().setTime("2016-6-28 15:13:02").setContext("快件在【相城中轉倉】裝車,正發往【無錫分撥中心】"));
        logisticsDatas.add(new LogisticsData().setTime("2016-6-28 15:13:02").setContext("【北京鴻運良鄉站】的【010058.269】正在派件"));
        logisticsDatas.add(new LogisticsData().setTime("2016-6-28 15:13:02").setContext("快件到達【濰坊市中轉部】,上一站是【】"));
        logisticsDatas.add(new LogisticsData().setTime("2016-6-28 15:13:02").setContext("快件在【濰坊市中轉部】裝車,正發往【濰坊奎文代派】"));
        logisticsDatas.add(new LogisticsData().setTime("2016-6-28 15:13:02").setContext("快件到達【濰坊】,上一站是【濰坊市中轉部】"));
        logisticsDatas.add(new LogisticsData().setTime("2016-6-28 15:13:02").setContext("快件在【武漢分撥中心】裝車,正發往【晉江分撥中心】"));
        logisticsDatas.add(new LogisticsData().setTime("2016-6-28 15:13:02").setContext("【北京鴻運良鄉站】的【010058.269】正在派件"));
        logisticsDatas.add(new LogisticsData().setTime("2016-6-28 15:13:02").setContext("【北京鴻運良鄉站】的【010058.269】正在派件"));
        logisticsDatas.add(new LogisticsData().setTime("2016-6-28 15:13:02").setContext("【北京鴻運良鄉站】的【010058.269】正在派件"));
        logisticsDatas.add(new LogisticsData().setTime("2016-6-28 15:13:02").setContext("【北京鴻運良鄉站】的【010058.269】正在派件"));

第二，找到你的控件併爲其設置NodeProgressAdapter適配器

        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，剩下的就是交給控件了，有興趣的童鞋可以看看源碼，寫的不是很好，多多指教，是不是很簡單呢；

值得注意的是使用此控件的童鞋，裏面有一個JavaBean需要實現，你也可以繼承自此Bean
