百度地图开发-将多个地点标记在地图上，点击节点弹出PopupWindow

最近在写一个安卓程序，用到了百度地图API的一些内容，就随便玩耍了一下。

这个DEMO是用来将多个地点标记在地图上，然后点击节点弹出PopupWindow

下面是一些截图：

main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.example.baidumaptest.MainActivity" >

    <LinearLayout
        android:id="@+id/ll_baidumap"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="horizontal"
        >

       <TextView
           android:id="@+id/tv_showinfo"
           android:layout_width="wrap_content"
           android:layout_height="wrap_content"
           />

    </LinearLayout>

      <com.baidu.mapapi.map.MapView
          android:id="@+id/bmapView"
          android:layout_width="fill_parent"
          android:layout_height="fill_parent" />

</RelativeLayout>

            android:text="地点："
