Android日常知識收集與總結之對話框異常

今天弄項目時發現一個有趣的錯誤BUG，特來記載一下，初步定義爲視圖加載的問題，

錯誤信息先沾上來:

java.lang.RuntimeException: Unable to start activity ComponentInfo

java.lang.RuntimeException: Unable to start activity ComponentInfo

java.lang.RuntimeException: Unable to start activity ComponentInfo

android.view.WindowManager$BadTokenException: Unable to add window -- token android.app.LocalActivityManager$LocalActivityRecord@422dc6e8 is not valid; is your activity running?

at android.widget.TabHost$IntentContentStrategy.getContentView(TabHost.java:768)

Andrdoid用仿iphone的TabBar是用TabHost+ActivityGroup來解決的，裏面用View堆棧的形式加載 Activity，在裏面的Activity用AlertDialog對話框是，報異常：android.view.WindowManager$BadTokenException: Unable to add window -- token android.app.LocalActivityManager$LocalActivityRecord@422dc6e8 is not valid; is your activity running?

把AlertDialog裏面的context：xxxActivity.this 改爲：：“xxxActivity.this..getParent()”就搞定！
