如何从Firebase或infoWindow中检索特定推送ID子代的所有数据 [英] How to retreive all of the data of a specific pushed ID Child from Firebase or, From a infoWindow

问题描述

我需要从Pu​​sh
生成的节点中获取所有存储的数据。这是我的结构：
$ b

我的所有节点都给这些不同的infoWindows
发送数据：
$ b $ 链接。

  FirebaseUtils.getPostRef（）。orderByKey（）。addChildEventListener（new ChildEventListener（）{
 @Override 
）public void onChildAdded（final DataSnapshot dataSnapshot，String s）{
 latitud = dataSnapshot.getValue（Post.class）.getLatitud（）; 
 longitudinal = dataSnapshot.getValue（Post.class）.getLongitud（） ; 
 
 titulo = dataSnapshot.getValue（Post.class）.getTitulo（）; 
 costo = dataSnapshot.getValue（Post.class）.getCosto（）; 
 mes = dataSnapshot .getValue（Post.class）.getMes（）; 
 numeroDia = dataSnapshot.getValue（Post.class）.getDia（）; 
 organizadoPor = dataSnapshot.getValue（Pos t.class）.getOrganizadoPor（）; 
 descripcion = dataSnapshot.getValue（Post.class）.getDescripicion（）; 
 hora = dataSnapshot.getValue（Post.class）.getHora（）; 
 minutos = dataSnapshot.getValue（Post.class）.getMinutos（）; 
 
 Post post = new Post（）; 
 //将所有数据添加到post对象例如post.setLatitud（latitud）; 
 
 BitmapDescriptor bm = BitmapDescriptorFactory.fromResource（R.mipmap.m5）; 
 LatLng latLng1 =新LatLng（纬度，纵向）; 
 mMarker = new MarkerOptions（）。position（latLng1）.title（titulo）.snippet（costo）.icon（bm）; 
 mp.add（mMap.addMarker（mMarker））; 
 
 //将您的发布数据与标记
 mMarker.setTag（post）; 
 
 
} 
}）; 
  

使用此方法检测标记点击次数

<$ （）$ {
$> $ $ $ $ $ $ {
$ on $ {$ b $ on $'$' b $ b Intent intent = new Intent（HomeActivity.this，OtherActivity.class）;
Bundle bundle = new Bundle（）;
//从点击的标记中获取数据并将其附加到
bundle.putSerializable（post，（Post）marker.getTag（））;
intent.putExtras（bundle）;
startActivity（intent）;
return true;
}
}）;
}

在您的OtherActivity中使用它来获取数据。

  Post mPost =（Post）getIntent（）。getSerializableExtra（post）; 
  

您的Post模式可能是这样的。

  public class Post实现Serializable {
 
私有字符串纬度，纵向，角度，titulo，mes， numeroDia，organizadoPor，descripcion，hora，minutos; 
 
 
 public String getLatitud（）{
 return latitud; 
} 
 
 public void setLatitud（String latitud）{
 this.latitud = latitud; 
} 
 
 public String getLongitud（）{
 return longitudinal; 
} 
 
 public void setLongitud（String longitudinal）{
 this.longitud = 
} 
 
 public String getCosto（）{
 return costo; 
} 
 
 public void setCosto（String costo）{
 this.costo = costo; 
} 
 
 public String getTitulo（）{
 return titulo; 
} 
 
 public void setTitulo（String titulo）{
 this.titulo = titulo; 
} 
 
 public String getMes（）{
 return mes; 
} 
 
 public void setMes（String mes）{
 this.mes = mes; 
} 
 
 public String getNumeroDia（）{
 return numeroDia; 
 
 
 public void setNumeroDia（String numeroDia）{
 this.numeroDia = numeroDia; 
} 
 
 public String getOrganizadoPor（）{
 return organizadoPor; 
} 
 
 public void setOrganizadoPor（String organizadoPor）{
 this.organizadoPor = organizadoPor; 
} 
 
 public String getDescripcion（）{
 return descripcion; 
 
 $ b $ public void setDescripcion（String descripcion）{
 this.descripcion = descripcion; 
} 
 
 public String getHora（）{
 return hora; 
} 
 
 public void setHora（String hora）{
 this.hora = hora; 
} 
 
 public String getMinutos（）{
 return minutos; 
} 
 
 public void setMinutos（String minutos）{
 this.minutos = minutos; 
} 
} 
  

I need to get all the stored data from the nodes generated by Push This is my structure:

All my nodes give data to various infoWindows like these:

Each infoWindow contains data specific to several nodes, what I need is to obtain that data from each of those infoWindows or specific nodes

I need these specific data to put them in another activity, either by getting the data from the node or from the infoWindow How do I do it?

This is the code that gives the data to the infoWindow:

   FirebaseUtils.getPostRef().orderByKey().addChildEventListener(new ChildEventListener() {
                    @Override
                    public void onChildAdded(final DataSnapshot dataSnapshot, String s) {
                        latitud = dataSnapshot.getValue(Post.class).getLatitud();
                        longitud = dataSnapshot.getValue(Post.class).getLongitud();

                        titulo = dataSnapshot.getValue(Post.class).getTitulo();
                        costo = dataSnapshot.getValue(Post.class).getCosto();
                        mes = dataSnapshot.getValue(Post.class).getMes();
                        numeroDia = dataSnapshot.getValue(Post.class).getDia();
                        organizadoPor = dataSnapshot.getValue(Post.class).getOrganizadoPor();
                        descripcion = dataSnapshot.getValue(Post.class).getDescripicion();
                        hora = dataSnapshot.getValue(Post.class).getHora();
                        minutos = dataSnapshot.getValue(Post.class).getMinutos();




                        BitmapDescriptor bm = BitmapDescriptorFactory.fromResource(R.mipmap.m5);
                        LatLng latLng1 = new LatLng(latitud, longitud);
                        mMarker = new MarkerOptions().position(latLng1).title(titulo).snippet(costo).icon(bm);
                        mp.add(mMap.addMarker(mMarker));
   }

I try with this But it only gives me the data of the last infoWindow:

  Post mPost = new Post();
  Intent intent =  new Intent(MainActivity.this, OtherActivity.class);
  intent.putExtra("abc", mPost):

the OtherActivity:

  Intent Intent = getIntent();
   mPost = (Post) intent.getSerializableExtra("abc");

解决方案

Edit your code to be like below.but you need to set data into your post object. you will attach your post data into your marker using mMarker.setTag(post); for more information have a look at this link.

   FirebaseUtils.getPostRef().orderByKey().addChildEventListener(new ChildEventListener() {
                    @Override
                    public void onChildAdded(final DataSnapshot dataSnapshot, String s) {
                        latitud = dataSnapshot.getValue(Post.class).getLatitud();
                        longitud = dataSnapshot.getValue(Post.class).getLongitud();

                        titulo = dataSnapshot.getValue(Post.class).getTitulo();
                        costo = dataSnapshot.getValue(Post.class).getCosto();
                        mes = dataSnapshot.getValue(Post.class).getMes();
                        numeroDia = dataSnapshot.getValue(Post.class).getDia();
                        organizadoPor = dataSnapshot.getValue(Post.class).getOrganizadoPor();
                        descripcion = dataSnapshot.getValue(Post.class).getDescripicion();
                        hora = dataSnapshot.getValue(Post.class).getHora();
                        minutos = dataSnapshot.getValue(Post.class).getMinutos();

                        Post post = new Post();
                        // add all your data to post object e.g post.setLatitud(latitud);

                        BitmapDescriptor bm = BitmapDescriptorFactory.fromResource(R.mipmap.m5);
                        LatLng latLng1 = new LatLng(latitud, longitud);
                        mMarker = new MarkerOptions().position(latLng1).title(titulo).snippet(costo).icon(bm);
                        mp.add(mMap.addMarker(mMarker));

                        // Associate your post data with the marker
                        mMarker.setTag(post);


                        }
                });

use this method to detect marker clicks

private void onMarkerClicked() {
    mMap.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener() {
        @Override
        public boolean onMarkerClick(Marker marker) {
            Intent intent = new Intent(HomeActivity.this, OtherActivity.class);
            Bundle bundle = new Bundle();
            // get the data from clicked marker and attach it with the intent 
            bundle.putSerializable("post", (Post) marker.getTag());
            intent.putExtras(bundle);
            startActivity(intent);
            return true;
        }
    });
}

in your OtherActivity use this to get the data .

  Post mPost = (Post) getIntent().getSerializableExtra("post");

your Post model could be like this.

public class Post implements Serializable{

   private String latitud,longitud,costo,titulo,mes,numeroDia,organizadoPor,descripcion,hora,minutos ;


public String getLatitud() {
    return latitud;
}

public void setLatitud(String latitud) {
    this.latitud = latitud;
}

public String getLongitud() {
    return longitud;
}

public void setLongitud(String longitud) {
    this.longitud = longitud;
}

public String getCosto() {
    return costo;
}

public void setCosto(String costo) {
    this.costo = costo;
}

public String getTitulo() {
    return titulo;
}

public void setTitulo(String titulo) {
    this.titulo = titulo;
}

public String getMes() {
    return mes;
}

public void setMes(String mes) {
    this.mes = mes;
}

public String getNumeroDia() {
    return numeroDia;
}

public void setNumeroDia(String numeroDia) {
    this.numeroDia = numeroDia;
}

public String getOrganizadoPor() {
    return organizadoPor;
}

public void setOrganizadoPor(String organizadoPor) {
    this.organizadoPor = organizadoPor;
}

public String getDescripcion() {
    return descripcion;
}

public void setDescripcion(String descripcion) {
    this.descripcion = descripcion;
}

public String getHora() {
    return hora;
}

public void setHora(String hora) {
    this.hora = hora;
}

public String getMinutos() {
    return minutos;
}

public void setMinutos(String minutos) {
    this.minutos = minutos;
}
 }
