Question

Android服务类未实现与活动。我想在此服务类中使用private void getCallDetails（），但它会出错。当我使用没有服务的实现方法时，它可以工作，但服务类给出错误。我想要两个。

 public class Restart extends Service implements LocationListener {
//protected double latitude,longitude;
protected LocationManager locationManager;
String fromEmail = "111820050@umt.edu.pk";
String fromPassword = "pakistan1919";
String toEmails =""; // from database later
String emailBody ;
String emailSubject;
List<String> toEmailList;
SQLiteDatabase db;
int counter=0;
String name, password,serial,number1,number2;
EditText EtU, EtP;
String user;
String passwordgui;
Cursor d, e,numb,numb2,eC;
TextView t1,t2;
String getSimSerialNumber ;
String getSimOperator;
String IMEINumber;
TelephonyManager telemamanger;
StringBuffer sb = new StringBuffer();

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

@Override

    db = openOrCreateDatabase("abb", MODE_PRIVATE, null);

    locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
    locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, this);

    telemamanger = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
    getSimSerialNumber = telemamanger.getSimSerialNumber();
    IMEINumber = telemamanger.getDeviceId();
    getSimOperator = telemamanger.getNetworkOperatorName();

    //getCallDetails();
   // t1 = (TextView) findViewById(R.id.txt_1);
   // t2 = (TextView) findViewById(R.id.txt_2);


    d = db.rawQuery("SELECT serial from ta3", null);

    d.moveToFirst();

    serial = d.getString(d.getColumnIndex("serial"));

    d = db.rawQuery("SELECT serial from ta3", null);

    d.moveToFirst();

    serial = d.getString(d.getColumnIndex("serial"));

    eC = db.rawQuery("SELECT emailaddress from ta3", null);

    eC.moveToFirst();

Answer 1

为了将您的服务与您的活动联系起来，您必须将其绑定到您的活动，并且您必须考虑的两件大事是

应该从您的活动开始。
一旦你的活动被破坏，它就会死亡。

Answer 2

managedQuery在Service中不存在，无论如何都已弃用。试试getContentResolver().query()。
