我有自己的布局对话框，其中包含一个地图片段。
public class DialogEditCustomer extends Dialog implements View.OnClickListener, OnMapReadyCallback, GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener {
private DialogEditCustomer.OnButtonClick onButtonClick;
private EditText etOwnerName, etOwnerNumber;
private TextView tvLatLong;
private Button buttonSave, buttonCancel;
private GoogleMap mMap;
private String ownerName, ownerNumber, latitude, longitude;
private FragmentManager fragmentManager;

SupportMapFragment mapFragment;
//initialize the dialog
public DialogEditCustomer(Context context, String ownerName, String ownerNumber, String latitude, String longitude, FragmentManager fragmentManager) {
super(context);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
this.setContentView(R.layout.dialog_edit_customer);
this.ownerName = ownerName;
this.ownerNumber = ownerNumber;
this.latitude = latitude;
this.longitude = longitude;
this.fragmentManager = fragmentManager;
this.context = context;
initViews();
if (context instanceof DialogEditCustomer.OnButtonClick) {
onButtonClick = (DialogEditCustomer.OnButtonClick) context;
}
}
//initialise views
private void initViews() {
tvLatLong = (TextView) findViewById(R.id.textViewLatLong);
etOwnerName = (EditText) findViewById(R.id.editTextOwnerName);
etOwnerNumber = (EditText) findViewById(R.id.editTextOwnerNumber);
buttonSave = (Button) findViewById(R.id.buttonSave);
buttonCancel = (Button) findViewById(R.id.buttonCancel);
if (mGoogleApiClient == null) {
mGoogleApiClient = new GoogleApiClient.Builder(context)
.addConnectionCallbacks(this)

}
if (ownerNumber != null) {
etOwnerNumber.setText(ownerNumber);
}
if (latitude != null && longitude != null) {
tvLatLong.setText(latitude + "," + longitude);
}
}
GoogleApiClient mGoogleApiClient;
@Override
public void onClick(View v) {
if (v == buttonSave) {
ownerName = etOwnerName.getText().toString();
ownerNumber = etOwnerNumber.getText().toString();
if (markerLatLong == null) {
latitude = "" + locationLatLong.getLatitude();
longitude = "" + locationLatLong.getLongitude();
} else {

}
onButtonClick.onSaveButtonClick(ownerName, ownerNumber, latitude, longitude);
}
if (v == buttonCancel) {
onButtonClick.onCancelButtonClick();
}
}
// implement for button clicks in activity and fragment
public interface OnButtonClick {
void onSaveButtonClick(String ownerName, String ownerNumber, String latitude, String longitude);
void onCancelButtonClick();
}
//only to be used in case of fragment
public void setListener(DialogEditCustomer.OnButtonClick onButtonClick) {
this.onButtonClick = onButtonClick;
}
@Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
try {
mMap.setMyLocationEnabled(true);
} catch (SecurityException e) {
e.printStackTrace();
}
LatLng sydney = new LatLng(locationLatLong.getLatitude(), locationLatLong.getLongitude());
MarkerOptions m1 = new MarkerOptions().draggable(true);
mMap.addMarker(m1.position(sydney).title(ownerName));
mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));
mMap.setOnMarkerDragListener(new GoogleMap.OnMarkerDragListener() {
@Override
public void onMarkerDragStart(Marker marker) {
}
@Override
public void onMarkerDrag(Marker marker) {
}
@Override
public void onMarkerDragEnd(Marker marker) {
markerLatLong = marker.getPosition();
}
});
}
@Override
public void onConnected(@Nullable Bundle bundle) {
try {
locationLatLong = LocationServices.FusedLocationApi.getLastLocation(
mGoogleApiClient);
} catch (SecurityException e) {
e.printStackTrace();
}
mapFragment.getMapAsync(this);
}
@Override
public void onConnectionSuspended(int i) {
}
@Override
public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {
}
@Override
protected void onStart() {
mGoogleApiClient.connect();
super.onStart();
}
@Override
protected void onStop() {
mGoogleApiClient.disconnect();
super.onStop();
}
}
这是我的布局XML

当我第一次打开对话框时，它会完美运行。
但是当我第二次打开它时，我得到了这个异常

如何摆脱这种情况？
答案 0 :(得分：1)
不确定这是否是正确的过程但是有效
@Override
protected void onStop() {
mGoogleApiClient.disconnect();
FragmentManager fm = fragmentManager;
Fragment fragment = (fm.findFragmentById(R.id.mapDialog));
if (fragment.isResumed()) {
FragmentTransaction ft = fm.beginTransaction();
ft.remove(fragment);
ft.commit();
}
super.onStop();
}
