服务类。

public class StartNotification extends Service {

    SharedPreferences sharedPreferences;
    String notification_Url = KP.KPURL.NOTIFICATION;
    public ProgressDialog pDialog;
    public Message m = new Message();
    private static final int PROCESS_START = 0;
    private static final int PROCESS_STOP = 1;

    // "2014-02-04 00:00:00"
    @Override
    public IBinder onBind(Intent intent) {
        throw new UnsupportedOperationException("Not yet implemented");
    }

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

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

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        processLoading();
        return super.onStartCommand(intent, flags, startId);
    }
public void storelocalDB() {
// my logic
}

    private void processLoading() {
        m.what = PROCESS_START;
        handler.sendMessage(m);
        storelocalDB();
        m = new Message();
        m.what = PROCESS_STOP;
        handler.sendMessage(m);
    }
private Handler handler = new Handler() {
        @Override
        public void handleMessage(Message msg) {
            switch (msg.what) {
            case PROCESS_START:
                pDialog = ProgressDialog.show(getApplicationContext(),
                        " Please wait...!", "Loading...", true, false);
                break;
            case PROCESS_STOP:
                if (pDialog.isShowing()) {
                    pDialog.dismiss();
                }
                break;
            }
        }
    };
}

Answer 1

首先尝试创建一个新对象：

ProgressDialog pdialog = new ProgressDialog(getActivity());

我没有看到你创建了一个对象。

Answer 2

我认为你不能从服务中显示ProgressDialog。更好的选择是你必须在活动中显示对话框，从那里开始服务并从那里注册接收器。当服务停止向活动发送广播并完成正在运行的进度对话框

android中服务类的进程对话框
