使用ScheduledExecutorService延时关闭一个全屏的对话框

自定义style,设置全屏属性

<resources>        <style name="AppTheme" parent="android:Theme.Black"/>      <style name="processDialog" >          <item name="android:windowIsFloating">true</item><!--是否浮现在activity之上-->           <item name="android:windowFullscreen">true</item>            <item name="android:windowIsTranslucent">false</item><!--半透明-->            <item name="android:windowNoTitle">true</item><!--无标题-->            <item name="android:windowBackground">@android:color/transparent</item><!--背景透明-->            <item name="android:backgroundDimEnabled">true</item><!--模糊-->            <item name="android:backgroundDimAmount">0.5</item>           <item name="android:alpha">0.3</item>       </style>      </resources>

代码中加载这个view并把view set到dialog上,这样全屏的dialog就完成了

mView = LayoutInflater.from(this).inflate(R.layout.process_dialog, null);  processDialog = new Dialog(context, R.style.processDialog);  processDialog.setCancelable(false);processDialog.setContentView(mView);  mAutoCloseDialog = new AutoCloseDialog(processDialog);mAutoCloseDialog.show(Prefs.DIALOG_DISPLAY_TIME);

接下来用一个封装好的类,做一个延时关闭的效果

import java.util.concurrent.Executors;import java.util.concurrent.ScheduledExecutorService;import java.util.concurrent.TimeUnit;import android.app.Dialog;public class AutoCloseDialog{          private Dialog dialog;      private ScheduledExecutorService executor = Executors.newSingleThreadScheduledExecutor();            public AutoCloseDialog(Dialog dialog){          this.dialog = dialog;      }            public void show(long duration){              Runnable runner = new Runnable() {              public void run() {                  dialog.dismiss();              }          };          executor.schedule(runner, duration, TimeUnit.MILLISECONDS);        dialog.show();    }        }

其他用法示例：
Here is a class with a method that sets up a ScheduledExecutorService to beep every ten seconds for an hour:

import static java.util.concurrent.TimeUnit.*; class BeeperControl {    private final ScheduledExecutorService scheduler =       Executors.newScheduledThreadPool(1);    public void beepForAnHour() {        final Runnable beeper = new Runnable() {                public void run() { System.out.println("beep"); }            };        final ScheduledFuture<?> beeperHandle =            scheduler.scheduleAtFixedRate(beeper, 10, 10, SECONDS);        scheduler.schedule(new Runnable() {                public void run() { beeperHandle.cancel(true); }            }, 60 * 60, SECONDS);    } }

ScheduledExecutorService执行周期性或定时任务
