'alertDialog.dismiss（）;'的onclick部 –

AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(YourActivity.this); 

       LayoutInflater inflater = YourActivity.this.getLayoutInflater(); 
       View dialogView = inflater.inflate(R.layout.dialog_image_source_chooser, null); 
       dialogBuilder.setView(dialogView); 

       ImageButton cameraButton = (ImageButton) dialogView.findViewById(R.id.cameraButton); 

    ImageButton galleryButton = (ImageButton) dialogView.findViewById(R.id.galleryButton); 


       final AlertDialog alertDialog = dialogBuilder.create(); 
       alertDialog.show(); 

       cameraButton.setOnClickListener(new View.OnClickListener() { 
        @Override 
        public void onClick(View view) { 

         alertDialog.dismiss(); 
         Intent cameraIntent = new Intent(SingleConversationActivity.this, CameraActivity.class); 
      cameraIntent.putExtra("EXTRA_CONTACT_JID", contact.getJid()); 
      startActivity(cameraIntent); 

        } 
       });
