Question

所以即时开发应用程序锁定服务。主活动有一个开关，只需分别使用startService()和stopService()在启动和停止服务之间切换。问题是，当我尝试停止服务时，它不会立即停止。我不知道如何阻止它。我甚至尝试在我的服务的stopself()中添加onDestroy()，但它不起作用

我的代码

public class LockerService extends Service {

String LockedApps[];
String allowedapp = null;
DataBaseHandler handler;
private ExecutorService executorService;
private ActivityManager activityManager = null;
String[] AppActivities = { .... };

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

@Override
public void onDestroy() {
    // TODO Auto-generated method stub
    super.onDestroy();
    if (executorService != null) {
        executorService.shutdown();
    }
    stopSelf();
    executorService.shutdown();
    Toast.makeText(getApplicationContext(), "service stopped",
            Toast.LENGTH_LONG).show();
}

@Override
public void onCreate() {
    super.onCreate();
    executorService = Executors.newSingleThreadExecutor();
    activityManager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
    LockerThread thread = new LockerThread();
    executorService.submit(thread);
    handler = new DataBaseHandler(this);
}

class LockerThread implements Runnable {

    Intent pwdIntent = null;

    public LockerThread() {
        pwdIntent = new Intent(LockerService.this, Locker.class);
        pwdIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    }

    @Override
    public void run() {
        while (true) {

            handler.open();
            LockedApps = handler.getPackages();
            boolean status = handler.checkdata("PACKAGE");
            handler.close();
            while (status) {
                String packname = activityManager.getRunningTasks(1).get(0).topActivity
                        .getPackageName();
                String activityname = activityManager.getRunningTasks(1)
                        .get(0).topActivity.getClassName();
                SharedPreferences sp = PreferenceManager
                        .getDefaultSharedPreferences(LockerService.this);
                allowedapp = sp.getString("allowedapp", "anon");
                // Log.i("activity name", activityname);
                if ((packname.equals("com.packagename"))
                        && (allowedapp.equals("com.packagename"))) {
                    // do nothing
                } else if ((packname.equals("com.packagename"))
                        && !(Arrays.asList(AppActivities)
                                .contains(activityname))) {

                    try {
                        Editor edit = sp.edit();
                        edit.putString("current_app", packname);
                        edit.commit();
                        startActivity(pwdIntent);
                        Thread.sleep(10000);
                    } catch (InterruptedException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                } else if ((Arrays.asList(LockedApps).contains(packname))
                        && (allowedapp.equals(packname))) {
                    // do nothing
                } else if ((Arrays.asList(LockedApps).contains(packname))) {
                    Editor edit = sp.edit();
                    edit.putString("current_app", packname);
                    edit.commit();
                    startActivity(pwdIntent);
                }
                try {
                    Thread.sleep(1500);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
        }

    }
}

}

您正在停止服务但线程仍在执行..您需要停止线程..因为您有一个while(true)循环，建议您指定一个布尔变量，该变量将设置为true on start和false on destroy和chenge the while to while（boolean_variable）

调用stopService（）时Android服务不会停止
