我目前正在为我的标签设置内容，例如
TabSpec spec1=tabHost.newTabSpec("TAB 1");
spec1.setContent(R.id.tab1);
spec1.setIndicator("", ressources.getDrawable(R.drawable.image_large));
但是如何将活动设置为此
的内容spec1.setContent(ProfileMenuAllTopics.this,MainActivity.class);
它说它不适用于此

/**
* This is a helper class that implements the management of tabs and all
* details of connecting a ViewPager with associated TabHost. It relies on a
* trick. Normally a tab host has a simple API for supplying a View or
* Intent that each tab will show. This is not sufficient for switching
* between pages. So instead we make the content part of the tab host
* 0dp high (it is not shown) and the TabsAdapter supplies its own dummy
* view to show as the tab content. It listens to changes in tabs, and takes
* care of switch to the correct paged in the ViewPager whenever the selected
* tab changes.
