概述
这篇比较简单，就是收藏自己的快递信息以后随便查阅进度，界面找了一些小logo显得比较干净整洁，数据库部分处理是使用了Xutil中的DbUtils部分来处理
1、快递收藏效果
在MyExpressActivity.java中的写了一个适配器
MyExpressAdapter adapter;，进入MyExpressAdapter.java中可以看出它继承BaseAdapter，其中核心是在getview部分
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
ViewHolder holder;
if (convertView == null) {
<span style="color:#009900;"> convertView = mInflater.inflate(R.layout.my_express_item,parent, false);</span>
holder = new ViewHolder();
holder.remarkName = (TextView) convertView.findViewById(R.id.tv_remark_name);
holder.expressNameAndNumber = (TextView) convertView.findViewById(R.id.tv_express_name_number);
holder.newInfo = (TextView) convertView.findViewById(R.id.tv_new_context);
holder.newTime = (TextView) convertView.findViewById(R.id.tv_new_time);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.remarkName.setText(lists.get(position).getName());
holder.expressNameAndNumber.setText(lists.get(position).getExpressName() + " " + lists.get(position).getExpressNumber());
holder.newInfo.setText(lists.get(position).getNewInfo());
holder.newTime.setText(lists.get(position).getNewDate());
return convertView;
}
在面绿色的布局文件中，就是这个效果的核心所在
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
xmlns:baiduadsdk="http://schemas.android.com/apk/res/com.weimeijing.feigeshudi"
>
<TextView
android:id="@+id/tv_remark_name"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="备注名称"
android:textColor="#FF000000"
android:textSize="15dp" />
<TextView
android:id="@+id/tv_express_name_number"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="快递名称 + 单号"
android:background="@drawable/mark"
android:textColor="@color/white"
android:textSize="13dp" />
<TextView
android:id="@+id/tv_new_context"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="最新信息"
android:textColor="#FF000000"
android:textSize="17dp" />
<TextView
android:id="@+id/tv_new_time"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="最新时间"
android:textColor="#FF353535"
android:textSize="13dp" />
</LinearLayout>
2、逻辑处理
在MyExpressActivity.java利用Xutil中的DbUtils部分来处理，来完成增删改查
