我在一个 Activity 中有以下代码,它为包含片段的布局启动一个对话框。
...
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工作得很好,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:

任何想法,什么可能导致此异常?我必须以某种方式卸载片段吗?
