上一篇参考了一位博友的文章,给大家分享了如何集成极光推送,没看上一篇的请先看上一篇
http://blog.csdn.net/gao_blog/article/details/79640279
今天主要和大家分享的是Android实现单点登录,俗称“挤下线”功能
第一步
首先第一步就是先集成好极光推送,我在上一篇文章中有讲到如何集成,本篇不再讲解;
第二步
在登录成功之后设置别名;
public static void setAlias(Context context, int sequence, String alias);
参数解释
sequence
- 用户自定义的操作序列号, 同操作结果一起返回,用来标识一次操作的唯一性。
alias
- 每次调用设置有效的别名,覆盖之前的设置。
- 有效的别名组成:字母(区分大小写)、数字、下划线、汉字、特殊字符@!#$&*+=.|。
- 限制:alias 命名长度限制为 40 字节。(判断长度需采用UTF-8编码)
举个例子
/**
* 极光推送
* 登录以后才能接收推送通知
*/
if(JPushInterface.isPushStopped(SelectionPlot.this)){
JPushInterface.resumePush(SelectionPlot.this);//恢复极光推送
}
JPushInterface.setAlias(this, 0, telephone);
第三步
接收到推送通知之后,实现退出登录,就要在MyReceiver里做操作了
package com.xhwl.xhwlownerapp.Reveiver;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.support.v4.content.LocalBroadcastManager;
import android.text.TextUtils;
import android.util.Log;
import com.xhwl.xhwlownerapp.JiGuang.ExampleUtil;
import com.xhwl.xhwlownerapp.activity.HomePageActivity;
import com.xhwl.xhwlownerapp.activity.LoginOwnerActivity;
import com.xhwl.xhwlownerapp.activity.TalkActivity.EstateTalkWaitingActivity;
import com.xhwl.xhwlownerapp.activity.TalkActivity.WaitingCallActivity;
import com.xhwl.xhwlownerapp.utils.SPUtils;
import org.json.JSONException;
import org.json.JSONObject;
import java.util.Iterator;
import cn.jpush.android.api.JPushInterface;
/**
* 自定义接收器
*
* 如果不定义这个 Receiver,则:
* 1) 默认用户会打开主界面
* 2) 接收不到自定义消息
*/
public class MyReceiver extends BroadcastReceiver {
private static final String TAG = "自定义消息";
private String type;
@Override
public void onReceive(Context context, Intent intent) {
try {
Bundle bundle = intent.getExtras();
Log.e(TAG, "[MyReceiver] onReceive - " + intent.getAction() + ", extras: " + printBundle(bundle));
if (JPushInterface.ACTION_REGISTRATION_ID.equals(intent.getAction())) {
String regId = bundle.getString(JPushInterface.EXTRA_REGISTRATION_ID);
Log.e(TAG, "[MyReceiver] 接收Registration Id : " + regId);
//send the Registration Id to your server...
} else if (JPushInterface.ACTION_MESSAGE_RECEIVED.equals(intent.getAction())) {
Log.e(TAG, "[MyReceiver] 接收到推送下来的自定义消息: " + bundle.getString(JPushInterface.EXTRA_MESSAGE));
processCustomMessage(context, bundle);
Bundle bundle1 = intent.getExtras();
String s = bundle1.getString(JPushInterface.EXTRA_MESSAGE);
// 在这里就是收到下线通知之后,就立马退出登录,直接下线
Bundle bundle2 = new Bundle();
if("下线通知".equals(s)){
SPUtils.clear(context);
Intent i = new Intent(context, LoginOwnerActivity.class); //单点登录
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
i.putExtras(bundle2);
context.startActivity(i);
JPushInterface.setAlias(context, 0, "");
//删除别名
JPushInterface.deleteAlias(context, 0);
}
} else if (JPushInterface.ACTION_NOTIFICATION_RECEIVED.equals(intent.getAction())) {
int notifactionId = bundle.getInt(JPushInterface.EXTRA_NOTIFICATION_ID);
Log.e(TAG, "[MyReceiver] 接收到推送下来的通知的ID: " + notifactionId);
} else if (JPushInterface.ACTION_NOTIFICATION_OPENED.equals(intent.getAction())) {
Log.e(TAG, "[MyReceiver] 用户点击打开了通知");
//打开自定义的Activity
Bundle bundle1 = intent.getExtras();
String s = bundle1.getString(JPushInterface.EXTRA_EXTRA);
Log.e("taskId",s+"");
try {
JSONObject obj = new JSONObject(s);
type = obj.getString("key");
}catch(JSONException e){
}
// 在这里是用户点击收到的推送通知,进入到登录页面
Bundle bundle2 = new Bundle();
Log.e("type",type+"");
if("下线通知".equals(type)){
SPUtils.clear(context);
Intent i = new Intent(context, LoginOwnerActivity.class); //单点登录
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
i.putExtras(bundle2);
context.startActivity(i);
JPushInterface.setAlias(context, 0, "");
//删除别名
JPushInterface.deleteAlias(context, 0);
}
} else if (JPushInterface.ACTION_RICHPUSH_CALLBACK.equals(intent.getAction())) {
Log.e(TAG, "[MyReceiver] 用户收到到RICH PUSH CALLBACK: " + bundle.getString(JPushInterface.EXTRA_EXTRA));
//在这里根据 JPushInterface.EXTRA_EXTRA 的内容处理代码,比如打开新的Activity, 打开一个网页等..
} else if(JPushInterface.ACTION_CONNECTION_CHANGE.equals(intent.getAction())) {
boolean connected = intent.getBooleanExtra(JPushInterface.EXTRA_CONNECTION_CHANGE, false);
Log.e(TAG, "[MyReceiver]" + intent.getAction() +" connected state change to "+connected);
} else {
Log.e(TAG, "[MyReceiver] Unhandled intent - " + intent.getAction());
}
} catch (Exception e){
}
}
// 打印所有的 intent extra 数据
private static String printBundle(Bundle bundle) {
StringBuilder sb = new StringBuilder();
for (String key : bundle.keySet()) {
if (key.equals(JPushInterface.EXTRA_NOTIFICATION_ID)) {
sb.append("\nkey:" + key + ", value:" + bundle.getInt(key));
}else if(key.equals(JPushInterface.EXTRA_CONNECTION_CHANGE)){
sb.append("\nkey:" + key + ", value:" + bundle.getBoolean(key));
} else if (key.equals(JPushInterface.EXTRA_EXTRA)) {
if (TextUtils.isEmpty(bundle.getString(JPushInterface.EXTRA_EXTRA))) {
Log.i(TAG, "This message has no Extra data");
continue;
}
try {
JSONObject json = new JSONObject(bundle.getString(JPushInterface.EXTRA_EXTRA));
Iterator<String> it = json.keys();
while (it.hasNext()) {
String myKey = it.next();
sb.append("\nkey:" + key + ", value: [" +
myKey + " - " +json.optString(myKey) + "]");
}
} catch (JSONException e) {
Log.e(TAG, "Get message extra JSON error!");
}
} else {
sb.append("\nkey:" + key + ", value:" + bundle.getString(key));
}
}
return sb.toString();
}
//send msg to MainActivity
private void processCustomMessage(Context context, Bundle bundle) {
if (HomePageActivity.isForeground) {
String message = bundle.getString(JPushInterface.EXTRA_MESSAGE);
String extras = bundle.getString(JPushInterface.EXTRA_EXTRA);
Intent msgIntent = new Intent(HomePageActivity.MESSAGE_RECEIVED_ACTION);
msgIntent.putExtra(HomePageActivity.KEY_MESSAGE, message);
if (!ExampleUtil.isEmpty(extras)) {
try {
JSONObject extraJson = new JSONObject(extras);
if (extraJson.length() > 0) {
msgIntent.putExtra(HomePageActivity.KEY_EXTRAS, extras);
}
} catch (JSONException e) {
}
}
LocalBroadcastManager.getInstance(context).sendBroadcast(msgIntent);
}
}
}
这里要注意的是,不管是接收到通知后下线,还是用户点击后下线,都要对别名进行重新设置
JPushInterface.setAlias(context, 0, "");
//删除别名
JPushInterface.deleteAlias(context, 0);
