百度地圖開發-將多個地點標記在地圖上，點擊節點彈出PopupWindow，節點popupwindow

最近在寫一個安卓程式，用到了百度地圖API的一些內容，就隨便玩耍了一下。

這個DEMO是用來將多個地點標記在地圖上，然後點擊節點彈出PopupWindow

下面是一些：

main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:paddingBottom="@dimen/activity_vertical_margin"    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>

popupwindow_showlocations.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"     android:background="#89D3D3D3"    >            <TextView             android:id="@+id/tv_locationname"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:text="地點："            android:textSize="20sp"            />                <TextView             android:id="@+id/tv_locationtime"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:text="時間："            android:textSize="20sp"            />        </LinearLayout>

android中PopupWindow彈出表單後,為何不可以點擊其他控制項

因為PopupWindow獲得了焦點，其他得不到焦點，所以無法點擊，把setFocusable設為false就行了。
 
百度地圖 我做的標記,過一段時間就開啟就會彈出資料被刪除,怎才可以不被刪除

因為你不是百度工作人員，還有就是你標記的廣告嫌疑太大咯。
