在我的清单中,我指定了(对于整个应用程序)样式:

  android:theme="@android:style/Theme.NoTitleBar"

然后在我的应用程序中,我想使用绘图缓存创建应用程序的屏幕截图:

  View activityView = getActivity().getWindow().getDecorView().findViewById(android.R.id.content);
  activityView.setDrawingCacheEnabled(true);
  Bitmap currentScreen = Bitmap.createBitmap(activityView.getDrawingCache());
  activityView.setDrawingCacheEnabled(false);

问题是屏幕截图上有一个空白(标题栏的大小).如果标题栏已打开,或者应用程序处于全屏模式,我会获得正确的屏幕截图.我尝试使用buildDrawingCache(true),但它没有任何区别.任何想法如何在noTitleBar模式下获得"真正的"屏幕截图？

上次更新后,我的应用有以下问题:

但是,我从不打电话requestWindowFeature或类似.也没有涉及对话.该报告本身来自BugSense,我自己从未遇到过这个问题.这是一个相当受欢迎的应用程序,该问题是Android Honeycomb 独有的:3.2,3.2.1和3.1.它在以前版本的应用程序中没有发生.自更新以来功能的唯一变化是我切换到的事实.onCreateActionBarSherlockActionBarCompat

任何人都发现了这个问题和/或有任何想法如何克服这个问题？ …
