com.com.adapterdialog.MainActivity has leaked window com.android.internal.policy.impl.PhoneWindow$De

在一个ListView的Item中，点击一个Item内的一张图片放大，我在ListView的Adapter中对该图片设置了监听，点击时弹出一个Dialog。然后切屏，报以下错误：

解决方法：
      在定义Activity的地方加上这个属性：android:configChanges="keyboardHidden|orientation"。当在xml文件中配置了android:configChanges="keyboardHidden|orientation"属性，在横紧屏切换的时候不会重新执行Activity的onCreate方法，只是执行onConfigurationChanged方法，否则切换的时候会重新执行onCreate方法。
