大家好，又见面了，我是你们的朋友全栈君。
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！
