hinzufügen 2 Taste Listview mit benutzerdefinierten Adapter

Question

i Problemen mit mir versuche, 2 Tasten in meinen Listview hinzufügen, ich bin mit einem Bild zu, was ich habe und was ich will

i Also, Ich möchte nur die 2 Tasten dort hinzufügen, aber ich habe versucht, es mit benutzerdefinierten Adaptern zu tun, aber ich kann es immer noch nicht tun, wenn jemand mir helfen könnte, würde ich es wirklich schätzen.

Meine Dateien so weit:

Vielen Dank, Jungs.

Answer 1

eine Klasse wie

public class TestAdapter extends BaseAdapter { 

    Context context; 

    public TestAdapter(Context context) 
    { 
     this.context=context; 
    } 

    //count of number of items in listview may be depending on the array ua passing....here i am keeping 5 it may be according to you! 
    int count=5; 

    @Override 
    public int getCount() { 
     return 5; 
    } 

    @Override 
    public Object getItem(int position) { 
     return null; 
    } 

    @Override 
    public long getItemId(int position) { 
     return 0; 
    } 

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 

     convertView= LayoutInflater.from(context).inflate(R.layout.row_item,parent,false); 

     TextView ordentitle=(TextView)convertView.findViewById(R.id.orden_title_text); 

     TextView textbox1=(TextView)convertView.findViewById(R.id.textbox1); 


     ordentitle.setText("Whatever yout text is"); 

     textbox1.setText("whatever your text is"); 

     Button editar=(Button)convertView.findViewById(R.id.edit_btn); 

     Button cancel=(Button)convertView.findViewById(R.id.cancel_btn); 


     editar.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       //funtionality of edit button 
      } 
     }); 

     cancel.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       //functionality of cancel button 
      } 
     }); 


     return convertView; 
    } 
} 

erstellen und dann diesen Adapter an Ihre Listenansicht in der Aktivität oder Fragment wie folgt festgelegt:

TestAdapter testAdapter=new TestAdapter(YourActivity.this) 

yourlistview.setAdapter(testAdapter); 

einen weiteren Zeiger:

SIE GAB EDIT TASTE id als cancel_btn und CANCEL BUTTON ID als edit_btn!

Answer 2

Sie könnten eine neue Klasse erstellen, die BaseAdapter erweitert, und in der getView-Methode, die Sie mit den Schaltflächen ausführen möchten. In der Aktivität mit dem listView verwenden Sie den setAdapter.
