Wie in dieser POJO Klasse I bin in der Lage zu setzen alle Werte auf meine recyclerview bt setzen bin mit Ich kann nicht auf die Wetter-Arraylist zugreifen und auch nicht in der Lage, die damit verbundenen Felder zu bekommen.

public class Weather extends BaseObservable implements Serializable { 

    @SerializedName("id") 
    long id; 
    @SerializedName("main") 
    String main; 
    @SerializedName("description") 
    String desc; 
    @SerializedName("icon") 
    String icon; 

    @Bindable 
    public long getId() { 
     return id; 
    } 

    public void setId(long id) { 
     this.id = id; 
     notifyPropertyChanged(BR.id); 
    } 

    @Bindable 
    public String getMain() { 
     return main; 
    } 

    public void setMain(String main) { 
     this.main = main; 
     notifyPropertyChanged(BR.main); 
    } 

    @Bindable 
    public String getDesc() { 
     return desc; 
    } 

    public void setDesc(String desc) { 
     this.desc = desc; 
     notifyPropertyChanged(BR.desc); 
    } 

    @Bindable 
    public String getIcon() { 
     return icon; 
    } 

    public void setIcon(String icon) { 
     this.icon = icon; 
     notifyPropertyChanged(BR.icon); 
    } 
} 

Layout-Datei:

<?xml version="1.0" encoding="utf-8"?> 
<layout xmlns:android="http://schemas.android.com/apk/res/android" 
    > 

    <data> 

     <import type="com.weatherappforleftshift.currentlocation.DateUtils"/> 

     <variable 
      name="daytemp" type="com.weatherappforleftshift.currentlocation.model.DayTemp"/> 


    </data> 

      <TextView 
        android:id="@+id/weather_status" 
        android:layout_width="wrap_content" 
        android:layout_marginLeft="10dp" 
        android:layout_marginStart="10dp" 
        android:text="@{HOW TO SET TEXT HERE FROM weathers list}"

Sie können an diesem GitHub Projekt suchen

https://github.com/arunshankar87/triptrial

ich die Daten umgegangen sind für eine recyclerview Bindung

Insbesondere die folgenden 2 Dateien Interesse sein

https://github.com/arunshankar87/triptrial/blob/master/app/src/main/java/com/arunshankar/triptrial/MyAdapter.java

Answer 2

in Ihrer VM hinzu:

@Bindable 
public String getWeathersText() { 
    StringBuilder builder = new StringBuilder(); 
    for (int i = 0; i < weathers.size(); i++) { 
     builder.append(weathers.get(i).getText); 
    } 
    return builder.toString(); 
} 

und in Ihrem Layout xml:

<TextView 
     android:id="@+id/weather_status" 
     android:layout_width="wrap_content" 
     android:layout_marginLeft="10dp" 
     android:layout_marginStart="10dp" 
     app:weathersText="@{daytemp.weathersText}" 
     android:layout_height="wrap_content" /> 

ich es nicht geprüft habe, aber ich denke, es sollte helfen ...
