ich bearbeitet haben und veröffentlicht die XML-Layout

HotelSearch.java:

public class HotelSearch extends Fragment { 
    Button button;RelativeLayout relativeLayout,relativeLayout1;int counter=0; 
@Override 
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable final Bundle savedInstanceState) { 

     View v=inflater.inflate(R.layout.hotel_search,container,false); 

     relativeLayout=((RelativeLayout) v.findViewById(R.id.roomlayout)); 
     button=(Button) v.findViewById(R.id.addroom); 
     button.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 

       relativeLayout1=new RelativeLayout(getContext()); 
       RelativeLayout.LayoutParams layoutParams=new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT,20); 
       layoutParams.addRule(RelativeLayout.BELOW,R.id.roomlayout); 
       relativeLayout1.setBackgroundColor(Color.parseColor("#000000")); 
       relativeLayout1.setLayoutParams(layoutParams); 
       Log.e("Counter",String.valueOf(counter+1)); 


        } 


     }); 
     return v; 
    } 
}

Sie verpassen einen Aufruf von addView(). Wahrscheinlich relativeLayout.addView (relativLayout1, layoutParams) ;? – Nanoc

wie die obige Methode zu verwenden.Bitte sagen Sie mir – jobin

Das war die vollständige Zeile, die Sie brauchen ... ersetzen Sie einfach Ihren Aufruf von setLayoutParams mit dieser Zeile. – Nanoc

verwenden xml

Ich habe nur eine ID auf das Layout, die Raumaufteilung enthält.

Dann fügen Sie einfach die Ansicht, dass das Layout stattdessen

public class HotelSearch extends Fragment { 
    Button button;RelativeLayout relativeLayout,relativeLayout1;int counter=0; 
@Override 
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable final Bundle savedInstanceState) { 

     View v=inflater.inflate(R.layout.hotel_search,container,false); 

     relativeLayout=((RelativeLayout) v.findViewById(R.id.rootlayout)); 
     button=(Button) v.findViewById(R.id.addroom); 
     button.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 

       relativeLayout1=new RelativeLayout(getContext()); 
       RelativeLayout.LayoutParams layoutParams=new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT,20); 
       layoutParams.addRule(RelativeLayout.BELOW,R.id.roomlayout); 
       relativeLayout1.setBackgroundColor(Color.parseColor("#000000")); 
       relativeLayout.addView(relativeLayout1, layoutParams); 
       Log.e("Counter",String.valueOf(counter+1)); 


        } 


     }); 
     return v; 
    } 
}

Hoffnung, das hilft.

Danke Nanoc.It hat funktioniert. – jobin

Ich möchte das relative Layout1 unter dem vorherigen hinzufügen, so oft die Schaltfläche geklickt wird. Bitte teilen Sie den Code dafür mit. – jobin

Posten Sie eine andere Frage, die eine Menge Code hinzufügen wird (im Grunde genommen und speichern Sie die ID des zuletzt erstellten Layouts, wenn Sie es selbst tun können). – Nanoc

Try this:

public class HotelSearch extends Fragment { 
Button button;RelativeLayout relativeLayout,relativeLayout1;int counter=0; 
@Override 
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable final Bundle savedInstanceState) { 

    View v=inflater.inflate(R.layout.hotel_search,container,false); 

    relativeLayout=((RelativeLayout) v.findViewById(R.id.roomlayout)); 
    button=(Button) v.findViewById(R.id.addroom); 
    button.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 

      relativeLayout1=new RelativeLayout(getContext()); 
      RelativeLayout.LayoutParams layoutParams=new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT,20); 
      layoutParams.addRule(RelativeLayout.BELOW,R.id.roomlayout); 
      relativeLayout1.setBackgroundColor(Color.parseColor("#000000")); 
      relativeLayout1.setLayoutParams(layoutParams); 
      Log.e("Counter",String.valueOf(counter+1)); 

       //this is added: 
      relativeLayout.addView(relativeLayout1); 


       } 


    }); 
    return v; 
}

}

Versucht es, aber zeigt immer noch den gleichen Weg – jobin

android können nicht hinzufügen relativelayout in Fragment dynamisch
