Android Share Content OnClick ListView

Question

У меня есть ListView и написать код блокирует его в порядке, и кнопка отмены:

builder.setNegativeButton("Exit", new DialogInterface.OnClickListener() { 
        public void onClick(DialogInterface dialog, int id) { 
         dialog.cancel(); 

        } 
       }); 
       builder.setPositiveButton("Share This Content", new DialogInterface.OnClickListener() { 
        public void onClick(DialogInterface dialog, int id) { 
         Notification note = new Notification(); 
         note.shareMessage("",answer);        
        } 
       }); 

и

public void shareMessage(String title, String message) { 
    Intent sharingIntent = new Intent(Intent.ACTION_SEND); 
    sharingIntent.setType("text/plain"); 
    String shareBody = title; 
    String copied = "\n\n Osmanlı Medrese İlimleri Uygulaması - Google Play "; 

    sharingIntent.putExtra(Intent.EXTRA_SUBJECT, message); 
    sharingIntent.putExtra(Intent.EXTRA_TEXT, shareBody + copied); 
    startActivity(Intent.createChooser(sharingIntent, "Paylaş")); 
} 

и это LogCat

Answer 1

I удаленный метод класса уведомления в класс MainActivity, где он называется:

общественного недействительный shareMessage (String название, String сообщение) {

Intent sharingIntent = new Intent(Intent.ACTION_SEND); 
    sharingIntent.setType("text/plain"); 
    String shareBody = title; 
    String copied = "\n\n Osmanlı Medrese İlimleri Uygulaması - Google Play "; 

    sharingIntent.putExtra(Intent.EXTRA_SUBJECT, message); 
    sharingIntent.putExtra(Intent.EXTRA_TEXT, shareBody + copied); 
    startActivity(Intent.createChooser(sharingIntent, getString(R.string.share))); 
}
