我在Activity中有以下代码,它启动包含片段的布局的对话框.

...
case R.id.pick_resource:
        dialog = new Dialog(this);
        dialog.setContentView(R.layout.resource_picker);
        dialog.setCancelable(true);
        dialog.setTitle("Pick a resource");
        dialog.show();

这在应用程序启动后第一次运行得非常好,但是当对话框退出并稍后再次调用时,我得到了这个堆栈跟踪:

我有以下问题:

我有一个现有的ListFragment,但我想将其显示为对话框.

我的第一种方法是创建一个DialogFragment必须ListFragment在其中的内容,但显然目前不可能将片段放入片段中.

由于方法的大量使用,延伸DialogFragment而不是ListFragment也是不可能的ListFragment.

是否有捷径可寻？
