那里）在我的应用中，我使用单DialogFragment来存储ListView中存储的ListFragment的添加和编辑项。我还要提到我的对话框在某些EditText上使用语音输入。
所以，问题是语音识别器活动将结果返回给它后，对话框不可见（嗯，实际上它在startActivityForResult()调用后立即变为不可见）。但对话仍然存在！我知道，因为当我旋转屏幕时，它会显示语音识别器活动返回的结果！仅当我从ListView项目的 contextMenu （到编辑项目）调用它时，它才会发生。当我从 optionsMenu （到添加项目）调用它时一切正常。
这是我的ProductDialogFragment.java：

这里的ListFragment（来自{{1>}的语音识别器来自项目上下文菜单使ProductDialogFragment不可见）：< / p>
DialogFragment我该怎么做才能解决这个问题？
