与 com.google.android.gms.maps.SupportMapFragment 、android 的另一个片段重复 id 、标记 null 或父 id？

Question

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;
private Context context;
private Location locationLatLong;
private LatLng markerLatLong;
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)
                .addOnConnectionFailedListener(this)
                .addApi(LocationServices.API)
                .build();
        mGoogleApiClient.connect();
    }
    mapFragment = (SupportMapFragment) fragmentManager
            .findFragmentById(R.id.mapDialog);

    buttonSave.setOnClickListener(this);
    buttonCancel.setOnClickListener(this);
    if (ownerName != null) {
        etOwnerName.setText(ownerName);
    }
    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 {
            latitude = "" + markerLatLong.latitude;
            longitude = "" + markerLatLong.longitude;
        }
        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

</LinearLayout>

当我第一次打开对话框时，它运行完美。

但是当我第二次打开它时出现这个异常

我该如何摆脱它？

Answer 1

不确定这是否正确，但它有效

@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();
}

与 com.google.android.gms.maps.SupportMapFragment 、android 的另一个片段重复 id 、标记 null 或父 id？

Duplicate id , tag null, or parent id with another fragment for com.google.android.gms.maps.SupportMapFragment , android?
