fragmentpageradapter getitem初始化执行两次
怎么解决这个问题

@Override
public Fragment getItem(int position) {
// TODO Auto-generated method stub

MainFragment fragment = new MainFragment();
Bundle b = new Bundle();

String title = Constant.TITLES[position];
b.putString("TITLES", title);
Log.i("send_titles", title);
fragment.setArguments(b);

return fragment;
}

getItem不就是每次去得到需要展示的Item吗？初始化执行两次？——>需要看下完整点的代码

接收数据的 Fragment public class MainFragment extends Fragment { private int mNewsType = 0; private static int sendtimes=0; String title =""; @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { // TODO Auto-generated method stub View v = inflater.inflate(R.layout.tab_item_fragment_main, null); TextView tip = (TextView) v.findViewById(R.id.id_tip); Bundle b = getArguments(); title = b.getString("TITLES"); Log.i("title_before", title); tip.setText(title ); Log.i("title_end", String.valueOf(sendtimes)); Log.i("title_end", title); Toast.makeText(this.getActivity(),"11---------"+title, Toast.LENGTH_SHORT).show(); //tip.setText(title ); return v; } @Override public void onActivityCreated(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onActivityCreated(savedInstanceState); Log.i("onActivityCreated", title); }

TabAdapter public class TabAdapter extends FragmentPagerAdapter { public TabAdapter(FragmentManager fm) { super(fm); // TODO Auto-generated constructor stub } @Override public Fragment getItem(int position) { // TODO Auto-generated method stub MainFragment fragment = new MainFragment(); Bundle b = new Bundle(); String title = Constant.TITLES[position]; b.putString("TITLES", title); Log.i("send_titles", title); fragment.setArguments(b); return fragment; } @Override public CharSequence getPageTitle(int position) { // TODO Auto-generated method stub return Constant.TITLES[position]; } @Override public int getCount() { // TODO Auto-generated method stub return Constant.TITLES.length; } }
