Answer 1

创建一个类像

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; 
    } 
} 

，然后在活动或片段该适配器设置为你的ListView这样的：

TestAdapter testAdapter=new TestAdapter(YourActivity.this) 

yourlistview.setAdapter(testAdapter); 

多了一个指针：

你给编辑按钮id为cancel_btn，并将CANCEL BUTTON ID设为edit_btn！

Answer 2

您可以创建一个扩展BaseAdapter的新类，并在getView方法中使用按钮执行所需的操作。在使用listView的活动中，您使用setAdapter。
