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
[java] view plain copy
- @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
[html] view plain copy
- <?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
