Answer 3

To use a specific style, use

ctw = new ContextThemeWrapper(this, R.style.MyStyle);
new AlertDialog.Builder(ctw)
    .setTitle(...)

Answer 4

I solved my problem by creating a class which extends Dialog, and I created my own functions. for example setMessage,setTitle,setPositiveButton,setNegativeButton etc.

But am confusing on how we can replace the setAdapter() and setSingleChoice().

Answer 5

Here one example For Dialog:

button = (Button) findViewById(R.id.button1);

            button.setOnClickListener(new OnClickListener() {

              @Override
              public void onClick(View arg0) {

                // custom dialog
                final Dialog dialog = new Dialog(context);
                dialog.setContentView(R.layout.custom);
                dialog.setTitle("Give a Title...");

                // set the custom dialog components - text, image and button
                TextView text = (TextView) dialog.findViewById(R.id.text);
                text.setText("Put here any custom text!");
                ImageView image = (ImageView) dialog.findViewById(R.id.image);
                image.setImageResource(R.drawable.ic_launcher);

                Button dialogButton = (Button) dialog.findViewById(R.id.ButtonOK);
                // if button is clickedthen dialog will closed
                dialogButton.setOnClickListener(new OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        dialog.dismiss();
                    }
                });

                dialog.show();
              }
            });

Custom AlertDialog

    AlertDialog.Builder builder;
    AlertDialog alertDialog;
    Context mContext;
    LayoutInflater inflater = (LayoutInflater)mContext.getSystemService(LAYOUT_INFLATER_SERVICE);
    View urlayoutfile = inflater.inflate(R.layout.custom_dialog_xmlfile,(ViewGroup)findViewById(R.id.Yourlayout_id));
    builder = new AlertDialog.Builder(this);
    builder.setView(urlayoutfile);
    alertDialog = builder.create(); 
    alertDialog.show();
