Here are the classes: This is the Fragment with the ListView on it, that i want to refresh, when the Dialog is closed. public class RegisterListFragment extends Fragment { public static final String TAG = "RegisterListFragment"; RegisterListAdapter adapter; @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { setRetainInstance(true); // TODO Auto-generated method stub View view =

I have an adapter with gridview that works as an Activity. I am trying to place it in a Fragment now and converted things but it does not work. When I include the IconFragmentSystem in my Activity I get a force close when I try to open the Activity. I know the Activity works because I can use other Fragments and everything is okay so I know my issue lies within this file. package com.designrifts.ultimatethemeui; import com.designrifts.ultimatethemeui.R; import android.content.Context; import android.content.Intent; import android.content.res.Resources; import android.net.Uri; import android.os

1、主要概念 ListView 用于将大数据集以列表的形式展示。 ListView 可以看成一个容器，它有如下继承链： View <- ViewGroup <- AdapterView <- AbsListView <- ListView 可见 ListView 继承自 AdapterView , 而 AdapterView 的作用就是为 ListView 提供数据。 主要的API: listView.setAdapter(adapter实例) 我们通常用的 Adapter 有如下几个： BaseAdapter , CursorAdapter , ArrayAdapter , SimpleAdapter .它们有如下的继承关系： Adapter <- ListAdapter <- BaseAdapter SimpleAdapter 、 CursorAdapter 和 ArrayAdapter 都是 BaseAdapter 的子类。 2、使用方法 在 Activity 布局文件中加入一个 ListView 组件 <ListView android:layout_width="match_parent" android:layout_height="wrap_content" android:entries="@array/listItems"></ListView> 这里

The AsyncTask runs when the user reaches the bottom of the listView. The problem is the BaseAdapter wont add new data.
