直接看代码吧

你需要在你的sub activity的oncreate方法这样获得content view

        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);
