从谷歌Firebase实时数据库读取谷歌地图标记数据时遇到问题

我有一个Firebase实时数据库，在那里我存储谷歌地图标记数据。它看起来像这样：Firebase数据库

我的应用程序可以选择将自己的标记添加到数据库中，我的问题是，当我通过应用程序添加标记时，我的应用软件只读取Studio 1和T1中的信息，而不是从.push((添加的随机键中读取信息。关于如何让它读取随机键下的标记信息，有什么想法吗？我的代码如下：

public class MapsActivity extends FragmentActivity implements 
OnMapReadyCallback, GoogleMap.OnMarkerClickListener {
FirebaseDatabase firebaseDatabase = FirebaseDatabase.getInstance();
DatabaseReference mProfileRef = firebaseDatabase.getReference("Studios");
ChildEventListener mChildEventListener;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps);
// Obtain the SupportMapFragment and get notified when the map is ready to be used.
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
Button addAStudio = (Button) findViewById(R.id.addAStudio);
addAStudio.setOnClickListener(new Button.OnClickListener() {
public void onClick(View v) {
Intent intent = new Intent(MapsActivity.this, Rent.class);
startActivity(intent);
}
});
}
@Override
public void onMapReady(GoogleMap googleMap){
googleMap.setOnMarkerClickListener(this);
LatLng  Copenhagen = new LatLng(55.67, 12.56);
googleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(Copenhagen, 18));
googleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
//get marker info from Firebase Database and add to map
addMarkersToMap(googleMap);
if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
return;
}
googleMap.setMyLocationEnabled(true);
}
@Override
public void onStop(){
if(mChildEventListener != null)
mProfileRef.removeEventListener(mChildEventListener);
super.onStop();
}
private void addMarkersToMap(final GoogleMap map){
mChildEventListener = mProfileRef.addChildEventListener(new ChildEventListener() {

@Override
public void onChildAdded(DataSnapshot dataSnapshot, String s) {
FirebaseMarker marker = dataSnapshot.getValue(FirebaseMarker.class);
String StudioName = marker.getStudioName();
String StudioAdress = marker.getStudioAddress();
String StudioDescription = marker.getStudioDescription();
double latitude = marker.getLatitude();
double longitude = marker.getLongitude();
LatLng location = new LatLng(latitude, longitude);
map.addMarker(new MarkerOptions()
.position(location)
.title(StudioName)
.snippet(StudioAdress)
.snippet(StudioDescription))
.showInfoWindow();
}
@Override
public void onChildChanged(DataSnapshot dataSnapshot, String s) {
}
@Override
public void onChildRemoved(DataSnapshot dataSnapshot) {
}
@Override
public void onChildMoved(DataSnapshot dataSnapshot, String s) {
}
@Override
public void onCancelled(DatabaseError databaseError) {
}
});
}
@Override
public boolean onMarkerClick(Marker marker) {
return false;
}

和

public class FirebaseMarker {
public String studioName;
public String studioDescription;
public String studioAddress;
public double latitude;
public double longitude;

//required empty constructor
public FirebaseMarker() {
}
public FirebaseMarker(String studioName, String studioDescription, String studioAdress, double latitude, double longitude) {
this.studioName = studioName;
this.studioDescription = studioDescription;
this.studioAddress = studioAdress;
this.latitude = latitude;
this.longitude = longitude;
}
public String getStudioName() {
return studioName;
}
public void setStudioName(String studioName) {
this.studioName = studioName;
}
public String getStudioDescription() {
return studioDescription;
}
public void setStudioDescription(String studioDescription) {
this.studioDescription = studioDescription;
}
public String getStudioAddress() {
return studioAddress;
}
public void setStudioAddress(String studioAddress) {
this.studioAddress = studioAddress;
}
public double getLongitude() {
return longitude;
}
public void setLongitude(double longitude) {
this.longitude = longitude;
}
public double getLatitude() {
return latitude;
}
public void setLatitude(double latitude) {
this.latitude = latitude;
}

}

最后在哪里向数据库添加新的标记：

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_rent);
saveStudio = findViewById(R.id.saveStudio);
studioNameTextField = findViewById(R.id.studioNameTextField);
studioInfoTextField = findViewById(R.id.studioInfoTextField);
studioAdressTextField = findViewById(R.id.studioAdressTextField);
mDatabase = FirebaseDatabase.getInstance();
mDataBaseRef = mDatabase.getReference("Studios");
saveStudio = findViewById(R.id.saveStudio);

saveStudio.setOnClickListener(new Button.OnClickListener() {
public void onClick(View v) {
Map<String, FirebaseMarker> newStudioAdd = new HashMap<>();
newStudioAdd.put(studioNameTextField.getText().toString(),
new FirebaseMarker(
studioNameTextField.getText().toString(),
studioInfoTextField.getText().toString(),
studioAdressTextField.getText().toString(),
53.669115, 12.560311
)
);
mDataBaseRef.push().setValue(newStudioAdd);
Intent intent = new Intent(Rent.this, MapsActivity.class);
startActivity(intent);
}
});
}

到目前为止，纬度和经度都是硬编码的，因为我希望它在继续之前读取标记。
