仿QQ修改密码后弹出对话框（Jpush推送下实现）

protected static boolean isTopActivity(Activity activity){
String packageName = "xxxxx";
ActivityManager activityManager = (ActivityManager) activity.getSystemService(Context.ACTIVITY_SERVICE);
List<RunningTaskInfo>  tasksInfo = activityManager.getRunningTasks(1);
if(tasksInfo.size() > 0){
System.out.println("---------------包名-----------"+tasksInfo.get(0).topActivity.getPackageName());
//应用程序位于堆栈的顶层
if(packageName.equals(tasksInfo.get(0).topActivity.getPackageName())){
return true;
}
}
return false;
}
需要添加android.permission.GET_TASKS权限

if (JPushInterface.ACTION_NOTIFICATION_RECEIVED.equals(intent.getAction())) {
Log.d(TAG, "[MyReceiver] 接收到推送下来的通知");

int notifactionId = bundle.getInt(JPushInterface.EXTRA_NOTIFICATION_ID);

String extras = bundle.getString(JPushInterface.EXTRA_EXTRA);
String messagetype = "";
try {
JSONObject extrasJson = new JSONObject(extras);
messagetype = extrasJson.getString("messagetype");
Log.i("messagetype------", messagetype);

//在前台运行执行它
