好久没写文章，今天遇到一个新需求，app正在通话过程切换到后台，点击通知栏的时候回到通话界面。

直接上代码吧

首先是实现通知的代码

NotificationCompat.Builder notificationBuild =null;    int NOTIFY_ID = 100;    NotificationManager mNotificationManager;    boolean isHasNotification = false;    android.app.Notification notification;    /**     * 显示通知栏     */    public void showNotification(String title,String content){        if (mNotificationManager == null&&!isHasNotification){            Intent deleteIntent = new Intent(this, NotificationTipsReceiver.class);            notificationBuild = new NotificationCompat.Builder(this);            notificationBuild.setAutoCancel(false);//设置能手动取消            notificationBuild.setOngoing(true);//设置不能取消            notificationBuild.setContentTitle(title);            notificationBuild.setSmallIcon(R.mipmap.icon);//设置图标            notificationBuild.setTicker("小尾巴 正在接单中");            notificationBuild.setDefaults(android.app.Notification.DEFAULT_ALL);            notificationBuild.setPriority(android.app.Notification.PRIORITY_MAX);            PendingIntent pendingIntent = PendingIntent.getBroadcast(this,                    0, deleteIntent, 0);            notificationBuild.setContentIntent(pendingIntent);            mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);        }        notification = notificationBuild.build();        mNotificationManager.notify(NOTIFY_ID, notification);        isHasNotification = true;    }

下面是通知点击处理类

public class NotificationTipsReceiver extends BroadcastReceiver {    @Override    public void onReceive(Context context, Intent intent) {        //判断app进程是否存活        boolean isApplive = SystemUtil.isAppAlive(context, "com.iol8.te.tr");        Intent  dialogIntent = new Intent(context, DialogueActivity.class);dialogIntent.setFlags(Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED|Intent.FLAG_ACTIVITY_NEW_TASK);//注意这里是关键  经过测试Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED也可以用Intent.FLAG_ACTIVITY_SINGLE_TOP  也可以做到   具体区别没有去深入测试        if (isApplive) {            if (WYIMManager.isDialogue) {                if (!SystemUtil.isAppRunningForeground(context)){//app在后台运行                    context.startActivity(dialogIntent);                }                return;            }        }    }}

另外附上一个Intent的flag 启动介绍（感谢这位大神的分享）
