Editext不接受用戶輸入的值

Question

在我的應用程序中有一個編輯文本，下面是一個帶有複選框的列表。當用戶選擇一個特定的複選框時，該值將顯示在edittext.Now中，如果用戶將一些值寫入所述的EditText，然後選擇對應的複選框，則哪個用戶已鍵入由選定value.I重寫要被顯示在的EditText兩個值的值

    private Context context; 
    private ArrayList<EmailModel> data; 
    DbHandler dbHandler; 
    int[] emails;

     } 


     holder.tvContact.setText(data.get(i).getEmail()); 


     return view; 
    } 


    private class ViewHolder { 
     TextView tvContact; 
     CheckBox checkBox; 

    } 
} 

Answer 1

這將顯示什麼是目前位於EditText中，新文本用逗號分隔。更改

holder.tvContact.setText(data.get(i).getEmail()); 

到

String s = holder.tvContact.gettext().toString(); 
holder.setText(s + ", " + data.get(i).getEmail());
