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:
