最近在看推送方面的知识，用的是信鸽推送主要是因为后台用的是信鸽
推送用第三方推送，也就是在客户端建一个广播接收器，当服务器发送消息时发送到信鸽，信鸽再发送一次，广播接受器接受下；
我实现的功能比较简单，当app在运行状态时，会在主页展示一个弹窗展示推送的消息；如果app不在运行状态且service没被销毁就展示默认的通知
那么如何在主页展示弹窗：当广播接受器收到我要的消息时，用观察者模式，收到消息在发送个消息个主界面

1.先按照官网的例子添加好权限及服务有些服务要改成自己的包名；
2.把官网的广播接受器先复制到自己的项目中，再在清单文件中添加；
3.随后添加从官网给出的3个AccessKey了
<meta-data android:name="com.tencent.rdm.uuid" android:value="eb5fa555d70c3246a4944f55be8c266b" /> <> <> <meta-data android:name="XG_V2_ACCESS_ID" android:value="2100219302" /> <> <meta-data android:name="XG_V2_ACCESS_KEY" android:value="A15KJ71W9ELC" />
4.现在在主界面中注册信鸽推送主要是获取一个token，然后可以上传给服务端，现在服务器就可以给你发送消息了；当然从信鸽官方后台可以发送消息，但是从信鸽后台发送的消息有时会接受不到，这点做的完全不及极光推送好
XGPushConfig.enableDebug(this, true);这句发布的时候记得改为false或删除
//信鸽start private String token; private Message message = null; private void XGInit() { // TODO Auto-generated method stub XGPushConfig.enableDebug(this, true); // 如果需要知道注册是否成功，请使用registerPush(getApplicationContext(), // XGIOperateCallback)带callback版本 // 如果需要绑定账号，请使用registerPush(getApplicationContext(),account)版本 // 具体可参考详细的开发指南 // 传递的参数为ApplicationContext //Context context = getApplicationContext(); //1.获取设备的Token Handler handler = new HandlerExtension(MainActivity.this); message = handler.obtainMessage(); XGPushManager.registerPush(getApplicationContext(), new XGIOperateCallback() { @Override public void onSuccess(Object data, int flag) { // TODO Auto-generated method stub Log.d("jiejie", "+++ register push sucess. token:" + data + " " + flag); token = data + ""; message.obj = "+++ register push sucess. token:" + data; System.out.println(token); message.sendToTarget(); } @Override public void onFail(Object data, int errCode, String msg) { // TODO Auto-generated method stub Log.d("jiejie", "+++ register push fail. token:" + data + ", errCode:" + errCode + ",msg:" + msg); message.obj = "+++ register push fail. token:" + data + ", errCode:" + errCode + ",msg:" + msg; message.sendToTarget(); } }); } private static class HandlerExtension extends Handler{ WeakReference<MainActivity> mActivity; HandlerExtension(MainActivity activity) { mActivity = new WeakReference<MainActivity>(activity); } @Override public void handleMessage(Message msg) { // TODO Auto-generated method stub super.handleMessage(msg); MainActivity theActivity = mActivity.get(); if(theActivity == null){ theActivity = new MainActivity(); } if(msg != null){ Log.d(Constants.LogTag, msg.obj.toString()); System.out.println("ddd"+msg.obj.toString()); } } }
5.修改广播接受器中的onTextMessage方法，当消息发送来时，将消息发送到主界面，不展示通知
不过你先要知道你app是否正在运行状态
/** * 判断是否运行在前台 * * @param context * @return */ public static boolean isRunningForeground(Context context) { String packageName = getPackageName(context); String topActivityClassName = getTopActivityName(context); Log.d("TAG", "packageName=" + packageName + ",topActivityClassName=" + topActivityClassName); if (packageName != null && topActivityClassName != null && topActivityClassName.startsWith(packageName)) { Log.d("TAG", "---> isRunningForeGround"); return true; } else { Log.d("TAG", "---> isRunningBackGround"); return false; } } // 方法2、通过RunningAppProcessInfo类判断（不需要额外权限）： public static boolean isBackground(Context context) { ActivityManager activityManager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE); List<RunningAppProcessInfo> appProcesses = activityManager.getRunningAppProcesses(); for (RunningAppProcessInfo appProcess : appProcesses) { if (appProcess.processName.equals(context.getPackageName())) { if (appProcess.importance == RunningAppProcessInfo.IMPORTANCE_BACKGROUND) { Log.i("后台", appProcess.processName); return true; } else { Log.i("前台", appProcess.processName); return false; } } } return false; }
6.通知EventBus来实现观察者模式在广播接收器中发送消息
// 消息透传 @Override public void onTextMessage(Context context, XGPushTextMessage message) { String text = "收到消息:" + message.toString(); EventBus.getDefault().post(text); System.out.println(text); // 获取自定义key-value PushTextMessage pushTextMessage = new PushTextMessage(); String title = message.getTitle(); String content = message.getContent(); pushTextMessage.setTitle(title); pushTextMessage.setContent(content); String customContent = message.getCustomContent(); if (customContent != null && customContent.length() != 0) { try { // JSONObject obj = new JSONObject(customContent); // // key1为前台配置的key // if (!obj.isNull("key")) { // String value = obj.getString("key"); // LogUtils.log(LogTag, "get custom value:" + value); // } CustomContent custom = com.alibaba.fastjson.JSONObject.parseObject(customContent, CustomContent.class); if (custom != null) { pushTextMessage.setCustomContent(custom); } // ... } catch (Exception e) { System.out.println(e + "d"); e.printStackTrace(); } } show(context, text); Log.d("jiejie", "pushTextMessage:" + pushTextMessage); // EventBus.getDefault().post(pushTextMessage); try { // APP自主处理消息的过程... boolean isForeground = AppUtil.isRunningForeground(context); Log.d("jiejie", isForeground + "d"); if (isForeground) { EventBus.getDefault().post(pushTextMessage); } else { notify(context, title, content); } } catch (Exception e) { System.out.println(e + "ddd"); e.printStackTrace(); }
7.在主界面中接受EventBus发送的消息，展示一个弹窗
@Subscribe public void onMessageReviced(final PushTextMessage pushTextMessage){ Log.d("jiejie", "好" + " 标题" +pushTextMessage.getTitle() + " 内容：" +pushTextMessage.getContent() + "CustomContent" + pushTextMessage.getCustomContent().getCmd()); if(pushTextMessage != null){ showAlertDialog(this, pushTextMessage); } } private void showAlertDialog(Context context,PushTextMessage text){ AlertDialog.Builder dialog = new AlertDialog.Builder(context); dialog.setTitle("推送的标题"); dialog.setMessage(text.getContent()); dialog.setPositiveButton("确认", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface arg0, int arg1) { // TODO Auto-generated method stub } }); AlertDialog mDialog = dialog.create(); mDialog.show(); } @Override protected void onDestroy() { // TODO Auto-generated method stub super.onDestroy(); EventBus.getDefault().unregister(this); }
