如何更改通知文本？
我正在开发一个android的应用程序。我有AlarmManager.This AlarmManager不能stoppable.Everytime（每2秒）根据随机数检查我的列表。随机数检查数据库并给予决定NotificationManager.İf列表行它不是绿色的。它是成功的。我的问题是当线是绿色的时候。我的通知文字没有变化。我该如何解决？
我的AlarmManagerReceiver：
DatabaseHelper mDatabaseHelper;
ArrayList listData = new ArrayList<>();
ArrayList listDataoran = new ArrayList<>();
ArrayList listDataBoya = new ArrayList<>();
ArrayList listDataId = new ArrayList<>();
ArrayList listDatanumber = new ArrayList<>();
Random secilmiskisi ;
int secilmissayı;
@Override
public void onReceive(Context context, Intent intent) {
mDatabaseHelper = new DatabaseHelper(context);
Cursor data = mDatabaseHelper.getData();
while(data.moveToNext()){
listDataId.add(data.getString(0));
listData.add(data.getString(1));
listDatanumber.add(data.getString(2));
listDataoran.add(data.getString(3));
listDataBoya.add(data.getString(4));}
secilmiskisi = new Random();
secilmissayı = secilmiskisi.nextInt(listDataId.size()) + 0;
Toast.makeText(context, "Alarm !!!!!!!!!!", Toast.LENGTH_LONG).show();
cancelAlarm(context);
// setalarm(context);
if(!listDataBoya.contains("#1eac02")){
String table = "people_table";
ContentValues productDetailsContentValues = new ContentValues();
productDetailsContentValues.put("boya", "#1eac02");
String where = " id = " + listDataId.get(secilmissayı);
mDatabaseHelper.update(table, productDetailsContentValues, where , null);

这是第一次创建活动：

答案 0 :(得分：0)
String subtext[]={"text one","text two","text three","text four"......}; int ran=new Random().nextInt(4);
android.app.Notification notif = new android.app.Notification.Builder(getApplicationContext())
.setContentTitle("M-Educate welcomes you the Digital era of learning")
.setSubText(subtext[ran])
.setSmallIcon(R.drawable.icn_app_icon)
.setLargeIcon(icon)
.setContentIntent(pendingIntent)
.setSound(alarmSound)
.build();
NotificationManager notificationManager = (NotificationManager) getApplicationContext().getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, notif);
注意：将文本设置为数组，并在每次触发通知时设置随机文本

您已全局声明了随机数，因此在整个过程中不会更改。
