我在这个活动中得到一个IllegalStateException,但不能确定发生了什么.这是QuickContactActivity中的ViewPagerAdapter类.
private class ViewPagerAdapter extends FragmentPagerAdapter {
public ViewPagerAdapter(FragmentManager fragmentManager) {
super(fragmentManager);
}
@Override
public Fragment getItem(int position) {
QuickContactListFragment fragment = new QuickContactListFragment();
final String mimeType = mSortedActionMimeTypes.get(position);
final List<Action> actions = mActions.get(mimeType);
fragment.setActions(actions);
return fragment;
}
@Override
public int getCount() {
return mSortedActionMimeTypes.size();
}
}
这是崩溃日志：
