The fragment // may still be created from its saved state, but there is // no reason to try to create its view hierarchy because it // won't be displayed. Note this is not needed -- we could // just run the code below, where we would create and return // the view hierarchy; it would just never be used. return null; } View root = inflater.inflate(R.layout.custom_list_fragment_content, null); return root; } 2. 需要外加控件自定义布局myfragment.xml: (包含custom_list_fragment_content.xml) <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent" > <TextView android:id="@+id/last_synctime_message" android:layout_width="match_parent" android:layout_height="@dimen/error_message_height" android:paddingLeft="8dip" android:paddingRight="8dip" android:gravity="right|center_vertical" android:text="@string/no_last_synctime" android:singleLine="true" android:ellipsize="end" android:background="@color/synctime_bar_background" android:visibility="gone" /> <View android:layout_width="match_parent" android:layout_height="1px" android:background="?android:attr/listDivider" /> <!-- 包含custom_list_fragment_content.xml --> <include layout="@layout/custom_list_fragment_content" android:id="@+id/list_panel" android:layout_width="match_parent" android:layout_height="0dip" android:layout_weight="1" /> <!-- Message list error overlays are dynamically inserted here --> </LinearLayout> 然后， public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View root = inflater.inflate(R.layout.myfragment, null); return root; } 有兴趣的同学可以看看源代码： package com.custom.listfragment.demo; import android.annotation.SuppressLint; import android.app.Fragment; import android.os.Bundle; import android.os.Handler; import android.view.View; import android.view.animation.AnimationUtils; import android.widget.AdapterView; import android.widget.ListAdapter; import android.widget.ListView; import android.widget.TextView; /** * 功能类似ListFragment,天机以下特性： * 1. 可下拉刷新，实现CustomListView.OnPullListener接口 * 2. 上拉加载（默认关闭） * 3.
