奇怪的SearchView行为(Strange SearchView behaviour)

 我最初使用ActionBarSherlock工作，但自从重新使用我的代码以使用android.support.v7库时，我在SearchView展开时看到一个模糊的蓝色叠加层。  
 以下是我的Nexus 7的屏幕截图，软键盘处于打开状态。  
 
 当我关闭键盘时，模糊的蓝色图像消失，但SearchView仍然存在模糊，如下图所示。  
 
 我正在使用菜单xml文件来创建各种菜单项 - 搜索项目如下...  
<item android:id="@+id/options_menu_search"
    android:title="@string/search"
    android:icon="@android:drawable/ic_menu_search"
    com.mycompany.mypackage:showAsAction="ifRoom|collapseActionView"
    com.mycompany.mypackage:actionViewClass="android.support.v7.widget.SearchView" >
</item>
 
 它实际上在我可以执行搜索的意义上工作，但对于我的生活，我无法解决模糊图像来自哪里。  
 我确实发现ActionBar中的这个SearchView drawables显得模糊，但是接受的答案不适用于我的问题，因为我没有以编程方式创建SearchView。  
 有没有人见过类似的东西并找到了修复方法？ 

I originally had this working with ActionBarSherlock but since re-working my code to use the android.support.v7 libraries I'm seeing a blurred blue overlay when the SearchView is expanded. 
The following is a screenshot from my Nexus 7 with the soft keyboard open. 
 
When I close the keyboard the blurred blue image disappears but there is still a blur to the SearchView as in the image below. 
 
I'm using a menu xml file to create the various menu items - the search item is as follows... 
<item android:id="@+id/options_menu_search"
    android:title="@string/search"
    android:icon="@android:drawable/ic_menu_search"
    com.mycompany.mypackage:showAsAction="ifRoom|collapseActionView"
    com.mycompany.mypackage:actionViewClass="android.support.v7.widget.SearchView" >
</item>
 
It does actually work in the sense I can perform searches but for the life of me I can't work out where the blurred images are coming from. 
I did find this SearchView drawables in ActionBar appear blurred but the accepted answer doesn't apply to my problem as I'm not creating the SearchView programatically. 
Has anybody seen anything similar and found a fix?

 你可以尝试我写的这个扩展方法来解决类似的问题  
public static async Task<bool> TryToAsync( Action action, int timeoutInSeconds )
        {
            var timeout = DateTime.Now.AddSeconds( timeoutInSeconds );
            while ( DateTime.Now < timeout )
            {
                try
                {
                    action();
                    return true;
                }
                catch ( Exception )
                {
                    await Task.Delay( 200 );
                }
            }

            return false;
        }

you can try this extension method which I wrote to solve similar type of problem 
public static async Task<bool> TryToAsync( Action action, int timeoutInSeconds )
        {
            var timeout = DateTime.Now.AddSeconds( timeoutInSeconds );
            while ( DateTime.Now < timeout )
            {
                try
                {
                    action();
                    return true;
                }
                catch ( Exception )
                {
                    await Task.Delay( 200 );
                }
            }

            return false;
        }
