android 官方的下拉刷新:SwipeRefreshLayout

效果如图:

<android.support.v4.widget.SwipeRefreshLayout    android:layout_width="match_parent"    android:layout_height="match_parent"    xmlns:android="http://schemas.android.com/apk/res/android"    android:paddingLeft="@dimen/activity_horizontal_margin"    android:paddingRight="@dimen/activity_horizontal_margin"    android:paddingTop="@dimen/activity_vertical_margin"    android:paddingBottom="@dimen/activity_vertical_margin"    android:id="@+id/swipe">    <ScrollView        android:layout_width="match_parent"        android:layout_height="match_parent">        <RelativeLayout            android:layout_width="match_parent"            android:layout_height="match_parent">             <TextView                android:layout_width="wrap_content"                android:layout_height="wrap_content"                android:text="Random number:"                android:id="@+id/lbl"/>             <TextView                android:layout_width="wrap_content"                android:layout_height="wrap_content"                android:id="@+id/rndNum"                android:layout_toRightOf="@id/lbl"/>              <TextView                android:layout_width="wrap_content"                android:layout_height="wrap_content"                android:layout_below="@id/lbl"                android:layout_centerHorizontal="true"                android:layout_marginTop="20dp"                android:text="Swipe to Refresh"                style="@android:style/TextAppearance.Medium"/>           </RelativeLayout>    </ScrollView></android.support.v4.widget.SwipeRefreshLayout>

import android.app.Activity;import android.os.Bundle;import android.os.Handler;import android.support.v4.widget.SwipeRefreshLayout;import android.support.v4.widget.SwipeRefreshLayout.OnRefreshListener;import android.widget.TextView;public class MainActivity extends Activity {private SwipeRefreshLayout swipe_container;private TextView tv;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);                swipe_container = (SwipeRefreshLayout) findViewById(R.id.swipe_container);        tv = (TextView)findViewById(R.id.textView1);                swipe_container.setColorSchemeResources(android.R.color.holo_blue_light, android.R.color.holo_red_light, android.R.color.holo_orange_light, android.R.color.holo_green_light);        swipe_container.setOnRefreshListener(new OnRefreshListener() {            @Override            public void onRefresh() {                tv.setText("正在刷新");                new Handler().postDelayed(new Runnable() {                    @Override                    public void run() {                        tv.setText("刷新完成");                        swipe_container.setRefreshing(false);                    }                }, 5000);            }        });    }}

在listView滑动的时候会有些问题，增加listview的一个监听，如下：

listView.setOnScrollListener(new AbsListView.OnScrollListener() {@Overridepublic void onScrollStateChanged(AbsListView absListView, int i) {}@Overridepublic void onScroll(AbsListView absListView, int firstVisibleItem,int visibleItemCount, int totalItemCount) {if (firstVisibleItem == 0)swipe_container.setEnabled(true);elseswipe_container.setEnabled(false);}});
