Android ListView物流获取追踪功能实现

这样，我们的Adapter就已经适配完成，下面我们在Activity中实验一下。

（三）：Activity实验：

package com.bobo.trace;
import java.util.ArrayList;
import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.widget.ListView;
import com.bobo.adapters.TraceAdapter;
import com.bobo.beans.Trace;
public class MainActivity extends Activity {
private ListView lv_trace;
private ArrayList<Trace> tradeLists = new ArrayList<Trace>();
private TraceAdapter ta;
private Context context;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
context = MainActivity.this;
initView();
}
private void initView(){
lv_trace = (ListView)findViewById(R.id.lv_trace);
initData();
ta = new TraceAdapter(tradeLists, context);
lv_trace.setAdapter(ta);
}
private void initData(){
tradeLists.add(new Trace(true, "商家已从广东发货", "15253157943", "2016-03-16 13:30:43"));
tradeLists.add(new Trace(false, "货物正在配送", "", "2016-03-16 18:30:43"));
tradeLists.add(new Trace(false, "货物已到达天津转运中心", "", "2016-03-17 13:30:43"));
tradeLists.add(new Trace(false, "货品已到济南货运站", "", "2016-03-18 13:30:43"));
tradeLists.add(new Trace(false, "货物已送达济南高新区站点", "", "2016-03-19 13:30:43"));
}
}

这样运行之后，我们就会发现，ListView的selector宽度是占满全屏的，这样，我们就需要编写一个inset来调整ListView的selector。

trace_divider.xml:

<?xml version="1.0" encoding="utf-8"?>
<inset xmlns:android="http://www.easck.com/apk/res/android" 
android:insetLeft="50dp"
android:drawable="@color/mgrey">
</inset>

这样，我们的物流追踪界面就算是完成了，很简单。
