可扩展的listview

这个效果出现在我自己的应用掌上快递，上面的。历史记录查询

如上面效果图所表示，快递查询的历史记录分条保存在数据库中，然后查出来显示出来。

其中，整个界面用的ListActivity，自带listview。

1.我需要在上面添加自定义标题栏，于是我把listview拿出来了，把listview单独放在一个lieanrLayout中。如图所示:

historyactivity_layout.xml

<?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="match_parent"    android:orientation="vertical" >    <FrameLayout        android:layout_width="match_parent"        android:layout_height="60dp"        android:background="@drawable/tab_black_bg"        android:orientation="horizontal" >        <Button            android:id="@+id/checkpackage_backBtn"            android:layout_width="65dp"            android:layout_height="40dp"            android:layout_gravity="left|center_vertical"            android:layout_marginLeft="5dp"            android:background="@drawable/back_button_normal"            android:gravity="center|center_vertical"            android:paddingLeft="5dp"            android:text="返回"            android:textColor="#FFFFFF" />        <TextView            android:layout_width="match_parent"            android:layout_height="match_parent"            android:gravity="center|center_vertical"            android:text="查询历史"            android:textColor="#FFFFFF"            android:textSize="23sp"            android:textStyle="bold" />    </FrameLayout>    <LinearLayout        android:id="@+id/historydetailinfolayout"        android:layout_width="match_parent"        android:layout_height="match_parent"        android:background="#FFFFFF"        android:orientation="vertical" >        <ListView            android:id="@android:id/list"            android:layout_width="match_parent"            android:layout_height="match_parent"            android:cacheColorHint="#00000000"            android:clickable="false"            android:divider="#C5C1AA"            android:dividerHeight="0dp"            android:scrollbarFadeDuration="300"            android:scrollbars="vertical" >        </ListView>    </LinearLayout></LinearLayout>

2.上面红色框框中，其实是一个整体，上面标题一个layout下面显示具体一个Layout包含一个textview，用于显示具体信息，然后通过事件监听控制展示还是隐藏。

checkpackagehisinfo_layout.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="wrap_content"    android:orientation="vertical" >    <RelativeLayout        android:id="@+id/titlelayout"        android:layout_width="fill_parent"        android:layout_height="60dp"        android:background="#FFFFFF"        android:paddingRight="10dp" >        <ImageView            android:id="@+id/workStatusImg"            android:layout_width="30dp"            android:layout_height="45dp"            android:layout_alignParentRight="true"            android:layout_centerVertical="true"            android:src="@drawable/mm_submenu_normal" />        <LinearLayout            android:id="@+id/leftlayout"            android:layout_width="match_parent"            android:layout_height="60dp"            android:layout_toLeftOf="@id/workStatusImg"            android:orientation="vertical" >            <TextView                android:id="@+id/his_companynamenumber"                android:layout_width="match_parent"                android:layout_height="0dp"                android:layout_weight="1"                android:gravity="left|center_vertical"                android:paddingLeft="5dp"                android:text="圆通快递：1234567543"                android:textColor="#4F4F4F"                android:textSize="20sp" />            <TextView                android:id="@+id/his_checkpackagetime"                android:layout_width="match_parent"                android:layout_height="0dp"                android:layout_weight="1"                android:gravity="left|center_vertical"                android:paddingLeft="5dp"                android:text="上次查询时间："                android:textColor="#4F4F4F"                android:textSize="20sp" />        </LinearLayout>    </RelativeLayout>    <View        android:layout_width="match_parent"        android:layout_height="1dp"        android:background="#838B8B" />    <LinearLayout        android:id="@+id/DetailLayout"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:background="@drawable/work_detail_unfold_bg"        android:orientation="vertical" >        <TextView            android:id="@+id/detailinfotxt"            android:layout_width="match_parent"            android:layout_height="wrap_content"            android:gravity="left|center_vertical"            android:padding="5dp"            android:textColor="#4F4F4F" />    </LinearLayout></LinearLayout>

3.java逻辑代码

listview数据源使用List<Map<String, Object>>  这样，我每一条历史记录就是一个map,方便取数据。，
