Итак, в своих примерах он утверждает, что PullToRefreshAttacher всегда должен создаваться в onCreate.
Однако с моим кодом
public class MainActivity extends FragmentActivity {
PagerAdapter adapter;
ArrayList<ImagePanel> mListOfImagePanel = new ArrayList<ImagePanel>();
ArrayList<String> mListOfImagePanelNames = new ArrayList<String>();
ListView mDrawerList;
ArrayAdapter<String> mDrawerListAdapter;
boolean doOnce = false;
DrawerLayout mDrawerLayout;
Flipper mFlip;
PullToRefreshLayout mPullToRefreshLayout;
private PullToRefreshAttacher mPullToRefreshAttacher;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//DO THESE FIRST
setContentView(R.layout.activity_main);
mPullToRefreshAttacher = PullToRefreshAttacher.get(this); // This line, nullpointerexception
Однако, когда я пытаюсь подключить PullToRefreshAttacher, он выдает исключение NullPointerException, так в чем здесь ошибка?
Вот мой логарифм:
