SwipeRefreshLayout简单使用

Activity：

import java.text.DateFormat;

import java.util.Date;

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;

import android.app.Activity;

public class SwipeRefreshActivity extends Activity implements OnRefreshListener{

private SwipeRefreshLayout swipeRefreshLayout;

private TextView dateTv;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

swipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.refresh);

dateTv = (TextView) findViewById(R.id.date);

swipeRefreshLayout.setOnRefreshListener(this);

}

@Override

public void onRefresh() {

swipeRefreshLayout.setRefreshing(true);

(new Handler()).postDelayed(new Runnable() {

@Override

public void run() {

swipeRefreshLayout.setRefreshing(false);

Date date = new Date(System.currentTimeMillis());

dateTv.setText(DateFormat.getDateTimeInstance().format(date));

}

}, 3000);

}

}

布局文件：

<android.support.v4.widget.SwipeRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android"

xmlns:tools="http://schemas.android.com/tools"

android:id="@+id/refresh"

android:layout_width="match_parent"

android:layout_height="match_parent"

tools:context=".SwipeRefreshActivity" >

<ScrollView

android:layout_width="match_parent"

android:layout_height="match_parent" >

<LinearLayout

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:orientation="vertical" >

<TextView

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="下拉刷新以产生当前日期" />

<TextView

android:id="@+id/date"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="日期" />

</LinearLayout>

</ScrollView>

</android.support.v4.widget.SwipeRefreshLayout>

感觉还是第三方的好，系统控件在不同版本系统上运行效果相差很大！
