android - stopService() 方法不停止服务

Question

当调用 Activity 退出时，我从调用类调用了 stopService() 方法，服务没有停止。它一直在后台运行，因此可能会给最终用户带来麻烦。任何帮助将不胜感激..

代码:

public class MainActivity2 extends ActionBarActivity {
ListView listView;
static int cnt1=0;
static int bob=1;
RelativeLayout background2;


public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_main_activity2);



background2 = (RelativeLayout) findViewById(R.id.background);
int num = 0;
final ListView theListView = (ListView) findViewById(R.id.listView);
Intent calledActivity = getIntent();
final List pe = calledActivity.getExtras().getStringArrayList("Caller1");

String[] s = new String[pe.size()];
for (int i = 0; i < pe.size(); i++) {
    s[i] = (String) pe.get(i);
}

final ListAdapter theAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, pe);
theListView.setAdapter(theAdapter);
final int cnt = 1;
Intent mIntent = new Intent(this, MyService.class);
mIntent.putStringArrayListExtra("Caller2", (ArrayList<String>) pe);
mIntent.putExtra("intCall",bob);
startService( mIntent);



theListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        String s1 = String.valueOf(parent.getItemAtPosition(position));
        pe.remove(s1);
        if (pe.size() == 0) {
            stopService(new Intent(MainActivity2.this, MyService.class));

            Intent goback;
            goback = new Intent(MainActivity2.this, MainActivity.class);
            startActivity(goback);
        }
        ((BaseAdapter) theAdapter).notifyDataSetChanged();


    }
});
}

我的服务等级:

public class MyService extends Service {
public MyService() {
}

@Override
public IBinder onBind(Intent arg0) {

return null;}

@Override
public void onCreate() {

    Toast.makeText(this, "Congrats! Blocker Created", Toast.LENGTH_LONG).show();

}

@Override
public void onStart(final Intent intent, int startId) {
int i=0;

    Timer t = new Timer();

    t.scheduleAtFixedRate(new TimerTask() {

                              @Override
                              public void run() {
                                  ActivityManager activityManager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
                                  List<ActivityManager.RunningTaskInfo> tasks = activityManager.getRunningTasks(1);


                                  ActivityManager.RunningTaskInfo ar = tasks.get(0);
                                  String activityOnTop=ar.topActivity.getClassName();
                                  Intent lockIntent = new Intent(MyService.this, LockScreen.class);
                                  lockIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                                  ComponentName componentInfo = tasks.get(0).topActivity;
                                  if(!componentInfo.getPackageName().equals("com.example.epiclapser.noprocrastinate"))
                                  {

                                        startActivity(lockIntent);
                                      Log.v("iwashere", "-- ACTIVITY --");
                                  }
                              }


                          },
            0,

            1000);

    Toast.makeText(this, "My Blocker Started", Toast.LENGTH_LONG).show();

}

@Override
public void onDestroy() {
    Toast.makeText(this, "MyService Stopped", Toast.LENGTH_LONG).show();
    super.onDestroy();
}


}

您的服务中的 onStart() 是一个已弃用的方法，您应该改用 onStartCommand。请参阅此链接 here .它还指出，默认情况下 onStart 会设置“START_STICKY”标志，这会导致服务在被终止后自动重新启动。我可以想象这会导致您的问题。尝试 OnStartCommand() 并让它返回“START_NOT_STICKY”标志。祝你好运!
