如何在Android中的Fragment中创建是/否警报对话框

Question

这是我的代码,我评论了我需要的东西.我尝试了一些代码,但似乎与Fragment不兼容.

public class main extends Fragment {

    ImageButton imagebutton;

    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.main, container, false);

        imagebutton = (ImageButton) rootView.findViewById(R.id.im);

        imagebutton.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                //Open Yes/No Dialog

                //if Yes do something
            }
        });

    }
}

试试这个方法:

   private void createAndShowAlertDialog() {
     AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
     builder.setTitle("My Title");
     builder.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
         public void onClick(DialogInterface dialog, int id) {
              //TODO
              dialog.dismiss();
         }
     });
     builder.setNegativeButton(android.R.string.cancel, new DialogInterface.OnClickListener() {
         public void onClick(DialogInterface dialog, int id) {
              //TODO
              dialog.dismiss();
         }
     });
     AlertDialog dialog = builder.create();
     dialog.show();
   }
