Question

你想在我的应用程序中播放闹钟，所以我尝试使用下面的代码使用服务当我点击开始按钮闹钟正在播放..但我想要的是，同样的活动我有两个editexts在第一我有时间9，第二个edittext我给了时间10，所以我必须只在晚上9点和10点显示通知......任何人都给我一些想法。

    public class DonnsAlarm extends Activity {
/** Called when the activity is first created. */
EditText e1,e2;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

   e1=(EditText)findViewById(R.id.editText1);
   e2=(EditText)findViewById(R.id.editText2);



    // click listener for the button to start service
    Button btnStart = (Button) findViewById(R.id.button1);
    btnStart.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
               String s1=e1.getText().toString();
                String s2=e2.getText().toString();

        Calendar cal = Calendar.getInstance();
        cal.set(Calendar.HOUR_OF_DAY, Integer.parseInt(s1));


        cal.add(Calendar.SECOND, 10);
        Intent intent = new Intent(DonnsAlarm.this, Service_class.class);
        PendingIntent pintent = PendingIntent.getService(DonnsAlarm.this, 0, intent,
                0);
        AlarmManager alarm = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
        alarm.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(),
                36000 * 1000, pintent);


 PendingIntent pintent1 = PendingIntent.getService(DonnsAlarm.this, 1, intent,
                0);

 cal.set(Calendar.HOUR_OF_DAY, Integer.parseInt(s2));
  alarm.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(),
                36000 * 1000, pintent1);




        }
    });

    // click listener for the button to stop service
    Button btnStop = (Button) findViewById(R.id.button2);
    btnStop.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            stopService(new Intent(getBaseContext(), Service_class.class));
        }
    });
}
      }
    public class Service_class extends Service {

 @Override
    public IBinder onBind(Intent arg0) {
        return null;
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        Toast.makeText(this, "Service Started", Toast.LENGTH_LONG).show();
        Intent notifyIntent = new Intent(Intent.ACTION_MAIN);
        notifyIntent.setClass(getApplicationContext(), DonnsAlarm.class);

        NotificationManager nm = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        CharSequence from ="It's Time to Play VocCards!";
        CharSequence message = "It's Time to Play VocCards!";

        PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notifyIntent, 0);


        Toast.makeText(this, "MyAlarmService.onUnbind()", Toast.LENGTH_LONG).show();

        Notification notif = new Notification(R.drawable.ic_launcher,
             "It's Time to Play VocCards!", System.currentTimeMillis());
       notif.setLatestEventInfo(this, from, message, contentIntent);
        nm.notify(1, notif);
        return START_STICKY;
    }

    @Override
    public void onDestroy() {

        super.onDestroy();
        Toast.makeText(this, "Service Stopped", Toast.LENGTH_LONG).show();

    }

    @Override
    public void onCreate() {
        super.onCreate();
    }
  }

Answer 1

我发现您的问题是将EditTexts的值提供给服务，以便服务知道播放警报的时间。您可以将EditText的值放到一个包（或intent的附加组件）中，并使用包含有关小时数据的意图启动服务。

在您的活动中使用：

btnStart.setOnClickListener(new View.OnClickListener() {

    @Override
    public void onClick(View v) {
        String s1=e1.getText().toString();
        String s2=e2.getText().toString();
        Intent intent = new Intent(getBaseContext(), Service_class.class);
        intent.putExtra("value1", s1);
        intent.putExtra("value2", s2);
        startService(intent);

    }
});

比在服务的onStartCommand方法中使用：

String val1 = intent.getExtra("value1");
String val2 = intent.getExtra("value2");

现在你有了服务中的价值！

Answer 2

    btnStart.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                String s1=e1.getText().toString();
                String s2=e2.getText().toString();

        Calendar cal = Calendar.getInstance();
        cal.set(Calendar.HOUR_OF_DAY, Integer.parseInt(s1));


        cal.add(Calendar.SECOND, 10);
        Intent intent = new Intent(DonnsAlarm.this, Service_class.class);
        PendingIntent pintent = PendingIntent.getService(DonnsAlarm.this, 0, intent,
                0);
        AlarmManager alarm = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
        alarm.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(),
                36000 * 1000, pintent);


 PendingIntent pintent1 = PendingIntent.getService(DonnsAlarm.this, 1, intent,
                0);

 cal.set(Calendar.HOUR_OF_DAY, Integer.parseInt(s2));
  alarm.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(),
                36000 * 1000, pintent1);



            }
        });

上面的代码根据第一个edittext中的值和一个根据另一个

的值设置两个警报

如何根据用户在Android中的edittext中输入值进行报警
