我有始终在后台运行的 Android 服务，以及由始终运行的服务触发的另一个服务，即警报管理器服务。
但是，我想用一个按钮停止服务，我的目标是停止一直在运行的服务，这样警报管理器服务就会自动停止。是正确的观点吗？
我的示例代码如下
package com.example.deneme;
public class AndroidNotifyService extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button buttonStartService = (Button)findViewById(R.id.startservice);
Button buttonStopService = (Button)findViewById(R.id.stopservice);
buttonStartService.setOnClickListener(new Button.OnClickListener(){
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
Intent intent = new Intent(AndroidNotifyService.this, com.example.deneme.AndroidScheduledService.class);
AndroidNotifyService.this.startService(intent);
}});
buttonStopService.setOnClickListener(new Button.OnClickListener(){
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
Intent intent = new Intent();
intent.setAction(AndroidScheduledService.ACTION);
intent.putExtra("RQS", AndroidScheduledService.RQS_STOP_SERVICE);
sendBroadcast(intent);
}});
}
}
我一直在运行的服务
package com.example.deneme;
public class AndroidScheduledService extends Service {
final static String ACTION = "AndroidScheduledServiceAction";
final static String STOP_SERVICE = "";
final static int RQS_STOP_SERVICE = 1;
public int onStartCommand(Intent intent, int flags, int startId) {
// TODO Auto-generated method stub
Intent myIntent = new Intent(getBaseContext(),
MyScheduledReceiver.class);
PendingIntent pendingIntent
= PendingIntent.getBroadcast(getBaseContext(),
0, myIntent, 0);
AlarmManager alarmManager
= (AlarmManager)getSystemService(ALARM_SERVICE);
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.add(Calendar.SECOND, 10);
long interval = 60 * 1000; //
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,
calendar.getTimeInMillis(), interval, pendingIntent);
return super.onStartCommand(intent, flags, startId);
}
@Override
public void onDestroy() {
// TODO Auto-generated method stub
//this.unregisterReceiver(notifyServiceReceiver);
Intent intent = new Intent();
intent.setAction(NotifyService.ACTION);
intent.putExtra("RQS", NotifyService.RQS_STOP_SERVICE);
sendBroadcast(intent);
super.onDestroy();
}
@Override
public IBinder onBind(Intent arg0) {
// TODO Auto-generated method stub
return null;
}
}
我的报警管理器服务
public class NotifyService extends Service {
final static String ACTION = "NotifyServiceAction";
final static String STOP_SERVICE = "";
final static int RQS_STOP_SERVICE = 1;
HttpClient httpclnt;
HttpPost httppst;
String message;
String response;
//NotifyServiceReceiver notifyServiceReceiver;
private static final int MY_NOTIFICATION_ID=1;
private NotificationManager notificationManager;
private Notification myNotification;
private final String myBlog = "http://android-er.blogspot.com/";
/*
@Override
public void onCreate() {
// TODO Auto-generated method stub
notifyServiceReceiver = new NotifyServiceReceiver();
super.onCreate();
}
*/
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
// TODO Auto-generated method stub
/*
IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction(ACTION);
registerReceiver(notifyServiceReceiver, intentFilter);
*/
// Send Notification
notificationManager =
(NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
myNotification = new Notification(R.drawable.ic_launcher,
"Notification!",
System.currentTimeMillis());
Context context = getApplicationContext();
String notificationTitle = "Exercise of Notification!";
String notificationText = "http://www.google.com/";
Intent myIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(myBlog));
PendingIntent pendingIntent
= PendingIntent.getActivity(getBaseContext(),
0, myIntent,
Intent.FLAG_ACTIVITY_NEW_TASK);
myNotification.defaults |= Notification.DEFAULT_SOUND;
myNotification.flags |= Notification.FLAG_AUTO_CANCEL;
myNotification.setLatestEventInfo(context,
notificationTitle,
notificationText,
pendingIntent);
notificationManager.notify(MY_NOTIFICATION_ID, myNotification);
return super.onStartCommand(intent, flags, startId);
}
@Override
public IBinder onBind(Intent arg0) {
// TODO Auto-generated method stub
return null;
}
@Override
public void onDestroy() {
// TODO Auto-generated method stub
//this.unregisterReceiver(notifyServiceReceiver);
super.onDestroy();
}
/*
@Override
public IBinder onBind(Intent arg0) {
// TODO Auto-generated method stub
return null;
}
public class NotifyServiceReceiver extends BroadcastReceiver{
@Override
public void onReceive(Context arg0, Intent arg1) {
// TODO Auto-generated method stub
int rqs = arg1.getIntExtra("RQS", 0);
if (rqs == RQS_STOP_SERVICE){
stopSelf();
}
}
}*/

我的广播接收器课程
对于 NotifyService 类包 com.example.deneme；
public class MyScheduledReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
Intent intent2 = new Intent(context, com.example.deneme.NotifyService.class);
context.startService(intent2);
}
}
对于 AndroidScheduledService 类
package com.example.deneme;
public class AutoStartNotifyReceiver extends BroadcastReceiver {
private final String BOOT_COMPLETED_ACTION = "android.intent.action.BOOT_COMPLETED";
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
if(intent.getAction().equals(BOOT_COMPLETED_ACTION)){
Intent myIntent = new Intent(context, com.example.deneme.AndroidScheduledService.class);
context.startService(myIntent);
}
}
}
