布局:

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:background="@color/game_find_gray"    android:orientation="vertical"    android:paddingBottom="56dp">    <RelativeLayout        android:layout_width="match_parent"        android:layout_height="60dp"        android:background="@color/titlecolor">        <TextView            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_centerInParent="true"            android:text="任务"            android:textColor="@color/white"            android:textSize="16sp" />    </RelativeLayout>    <in.srain.cube.views.ptr.PtrClassicFrameLayout        android:id="@+id/pcfl_content"        android:layout_width="match_parent"        android:layout_height="wrap_content">            <ScrollView                android:id="@+id/sv_content"                android:layout_width="match_parent"                android:layout_height="wrap_content"                android:fillViewport="true"                android:scrollbars="none">                <LinearLayout                    android:id="@+id/myscroll_header"                    android:layout_width="match_parent"                    android:layout_height="wrap_content"                    android:orientation="vertical">这里各种复杂的布局巴拉巴拉......               </LinearLayout>            </ScrollView>    </in.srain.cube.views.ptr.PtrClassicFrameLayout></LinearLayout>

查找控件并初始化

//得到下拉刷新控件final ScrollView sv_content = (ScrollView) findViewById(R.id.sv_content);pcfl_content = (PtrClassicFrameLayout) findViewById(R.id.pcfl_content);pcfl_content.setKeepHeaderWhenRefresh(true);pcfl_content.setPtrHandler(new PtrDefaultHandler() {    @Override    public boolean checkCanDoRefresh(PtrFrameLayout frame, View content, View header) {        // 这个方法用于判断是否可以刷新,比如在scrollview中,只有当scrollview滑到顶部才可以刷新        return PtrDefaultHandler.checkContentCanBePulledDown(frame, sv_content, header);    }    @Override    public void onRefreshBegin(final PtrFrameLayout frame) {        getGameData();    }});

得到最新数据之后:

pcfl_content.refreshComplete();
