Alarmmanager与未决的意图 [英] Alarmmanager with pending Intent

问题描述

下code片段......

The code snippet below....

    public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    ///////////Do something////////////////////////
    showtext.startScan();
    //SEt Alarm
    Intent intent = new Intent(this, TextReceiver.class);
    PendingIntent pi=PendingIntent.getBroadcast(this, 0, intent, 0);
    AlarmManager am=(AlarmManager) getSystemService(Context.ALARM_SERVICE);
    am.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis()+9000, pi);}

和我的接收机

TextReceiver extends BroadcastReceiver{

public void onReceive(Context context, Intent intent) 
{
///Show text/////
}
}

的事情是，当我9sn后运行程序，我该得到一个错误该应用程序停止unexpextdly。 。我的目标是显示文本​​每9sn
为什么我得到这个错误？
什么是alarmmanager在主要活动的正确用法？
或者我应该设置在广播接收器报警？
哪一个不使我的目标而言意义am.setRepeating或am.set？

The thing is that when I run the program after 9sn, I am getting an error that "The app stopped unexpextdly." . My goal is to show the text every 9sn Why I get this error ? What is the correct usage of alarmmanager in the main activity ? OR Should I set alarm in the BroadcastReceiver ? Which one does make sense am.setRepeating or am.set in terms of my goal ?

*的编辑：我怎样才能改变我的报警code在广播接收器上运行？ * 的

推荐答案

//试试这个

AlarmManager am=(AlarmManager)getApplicationContext getSystemService(Context.ALARM_SERVICE);

PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0,  intent, PendingIntent.FLAG_CANCEL_CURRENT);

  am.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(),(9 * 1000), pendingIntent);
