解决ActivityGroup的sub Activity中spinner BadTokenException的问题

在ActivityGroup的sub activity中直接使用Spinner会遇到这样的问题。?

?

View contentView = LayoutInflater.from(BrowseGroup.BROWSE_GROUP).inflate(R.layout.browse, null); pageNoSpinner = (Spinner) contentView.findViewById(R.id.pageNo); ArrayAdapter<Integer> adapter = new ArrayAdapter<Integer>(BrowseGroup.BROWSE_GROUP, android.R.layout.simple_spinner_item); for(int i=1;i<=16;i++){ adapter.add(i); } pageNoSpinner.setAdapter(adapter); riddlesListView = (ListView) contentView.findViewById(R.id.categories);setContentView(contentView);?不能直接调用setContentView(R.layout.browse);
