4.singletonf类:
/** * 用于存储消息数目 * created by admin on 2017/9/4. */ public class singletonf{ private int info_number=0; private static class singletonholder { /** * 单例对象实例 */ static final singletonf instance = new singletonf(); } public static singletonf getinstance() { return singletonholder.instance; } /** * private的构造函数用于避免外界直接使用new来实例化对象 */ private singletonf() {} public int getinfo_number() { return info_number; } public void setinfo_number(int info_number) { this.info_number = info_number; } // /** // * 若singletonf implements serializable则必须实现readresolve方法 // * readresolve方法应对单例对象被序列化时候 // */ // private object readresolve() { // return getinstance(); // } }
5.mybroadcastreceiver类:
import java.text.simpledateformat; import java.util.date; import android.app.notification; import android.app.notificationmanager; import android.app.pendingintent; import android.content.broadcastreceiver; import android.content.context; import android.content.intent; import android.os.handler; import android.os.message; import android.support.v4.app.notificationcompat; import android.util.log; import android.widget.remoteviews; public class mybroadcastreceiver extends broadcastreceiver { private singletonf singletonf; private context context1; @override public void onreceive(context context, intent intent) { this.context1 = context; // if (intent.getstringextra("info").equals("广播发送了")) { // log.i("静态广播:", "广播我已经接受了"); // } message message = handler.obtainmessage(); message.what = 0; handler.sendmessage(message); } private handler handler = new handler() { @override public void handlemessage(message msg) { switch (msg.what) { case 0: singletonf = singletonf.getinstance(); int first = singletonf.getinfo_number(); first++; date nowtime = new date(system.currenttimemillis()); simpledateformat sdformatter = new simpledateformat("hh:mm"); string retstrformatnowdate = sdformatter.format(nowtime); singletonf.setinfo_number( first); remoteviews contentviews = new remoteviews(context1.getpackagename(), r.layout.layout_item); // 通过控件的id设置属性 contentviews.setimageviewresource(r.id.imageview1, r.mipmap.ic_launcher_round); contentviews.settextviewtext(r.id.textview1, "消息标题"); contentviews.settextviewtext(r.id.textview2, "消息内容"); contentviews.settextviewtext(r.id.textview3, " (" + first + "条新消息)"); contentviews.settextviewtext(r.id.textview4, "" + retstrformatnowdate); // 点击通知栏跳转的activity intent intent = new intent(context1, actdetail.class); pendingintent pendingintent = pendingintent.getactivity(context1, 0, intent, pendingintent.flag_cancel_current); notificationcompat.builder mbuilder = new notificationcompat.builder(context1) .setsmallicon(r.mipmap.ic_launcher_round).setticker("new message"); // 自动管理通知栏消息 mbuilder.setautocancel(true); mbuilder.setcontentintent(pendingintent); /// 自定义布局 mbuilder.setcontent(contentviews); // 使用默认提示音 mbuilder.setdefaults(notification.default_all); notificationmanager mnotificationmanager = (notificationmanager) context1 .getsystemservice(context1.notification_service); // notify(int id, notification notification)若id为同一个值,则通知栏只会显示一行,并不停更新此消息内容 // 若为类似uuid.randomuuid().hashcode()这样不同的唯一标识符,则有几条消息通知栏就显示几行 mnotificationmanager.notify(1, mbuilder.build()); break; default: break; } } }; }
6.mainactivity类:
import android.content.intent; import android.support.v7.app.appcompatactivity; import android.os.bundle; import android.view.view; import android.widget.textview; public class mainactivity extends appcompatactivity { private textview tv_show; private int btn_number = 0; @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.activity_main); tv_show = (textview) this.findviewbyid( r.id.tv_show); tv_show.setonclicklistener(new view.onclicklistener() { @override public void onclick(view view) { shownotify(); btn_number++; tv_show.settext("发送了" + btn_number + "次广播"); } }); } private void shownotify() { intent intent = new intent(); intent.setaction("massage_notification"); // intent.putextra("info", "广播发送了"); sendbroadcast(intent); } @override protected void onstop() { btn_number = 0; tv_show.settext("发送了" + btn_number + "次广播"); super.onstop(); } @override protected void onpause() { btn_number = 0; tv_show.settext("发送了" + btn_number + "次广播"); super.onpause(); } @override protected void ondestroy() { btn_number = 0; super.ondestroy(); } }
7.actdetail类:
import android.app.notificationmanager; import android.content.context; import android.os.bundle; import android.support.annotation.nullable; import android.support.v7.app.appcompatactivity; /** * created by admin on 2017/9/4. */ public class actdetail extends appcompatactivity{ notificationmanager notificationmanager; singletonf singletonf; @override protected void oncreate(@nullable bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.activity_detail); singletonf = singletonf.getinstance(); notificationmanager = (notificationmanager) getsystemservice(context.notification_service); notificationmanager.cancel(1); singletonf.setinfo_number(0); } }
