我正在卸載一個應用程序android.I有AlarmManager.This AlarmManager不能stoppable.Everytime（每2秒）根據隨機數檢查我的列表。隨機數檢查數據庫並給予決定NotificationManager.İf列表行是不green.It使it.My問題是，當行green.My通知文本沒有按「餘噸change.How可以修復它如何更改通知文本？

我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";

}

這是第一次活動有創建：enter image description here

Thi s是最後一次活動：enter image description here

我想在選定號碼的行（隨機數）爲綠色時更改通知文本。

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])

注：設置你的文本作爲一個數組中，並在每次射擊的通知

它沒有工作。我的問題是當while循環沒有工作，當線變綠。它沒有顯示文本.. –

時間設置隨機文本試試這個代碼，替換現有的一個：

您已經在全局聲明瞭隨機數，所以在整個過程中它不會改變。

對不起，我不明白你的意思是什麼，隨機放置在本地。我把你的代碼複製到我的broadcastreceiver.It –

+0

隨機數字發生器應該在if語句裏 –

+0

我刷新了你的代碼，你是不是這個意思？因爲它沒有工作。如果我做錯了。只要說我是begrenerner在broadcastReceiver。 –
