slidingMenu 百度地图在Fragment中切换黑边解决方法

 由于android opengl绘制机制的原因，在使用slidingMenu和百度地图在切换的时候会出现黑边的现象，查了百度地图官方也没有找到好的解决办法，于是想到使用截图的方式来解决，大致的步骤如下：

1.slidingMenu打开的时候调用BaiduMap的snapshot方法截图获取Bitmap对象；

2.使用ImageView替换BaiduMap View并显示截取的图片;

3.slidingMenu关闭后再显示BaiduMap VIew。

主要代码：

fragmetn_map.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">
     <ImageView
         android:id="@+id/image_temp"
         android:layout_width="match_parent"
         android:layout_height="match_parent"
         android:visibility="gone"/>
    <com.baidu.mapapi.map.MapView
        android:id="@+id/bmapView"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:clickable="true" />
</LinearLayout>
