Answer 1

Try to do this, you just have to select the default selection and add to the dialog an integer -> inputSelection

final CharSequence[] items = { " HDMI IN ", " AV IN" };

        // Creating and Building the Dialog
        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setTitle("Select Input Type");

        builder.setSingleChoiceItems(items,inputSelection,
                new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int item) {
                        inputSelection = item;
                        levelDialog.dismiss();
                    }
                });
        levelDialog = builder.create();
        levelDialog.show();

My method making Custom dialog

http://www.helloandroid.com/tutorials/how-display-custom-dialog-your-android-application reference from here

1. Create one xml custom dialog

      <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content" >
   
       <RadioButton
           android:id="@+id/rd_!"
           android:layout_width="wrap_content"
           android:layout_height="wrap_content"
           android:text="A" />
   
       <RadioButton
           android:id="@+id/rd_2"
           android:layout_width="wrap_content"
           android:layout_height="wrap_content"
           android:layout_below="@+id/rd_!"
           android:text="B" />
   
       <Button
           android:layout_width="fill_parent"
           android:layout_height="wrap_content"
           android:layout_below="@+id/rd_2"
           android:layout_centerInParent="true"
           android:text="OK" />
       </RelativeLayout>
   

and activity.java file

  Dialog dialog = new Dialog(Dialogeshow.this);
    dialog.setContentView(R.layout.custom_dialoge);
    dialog.setTitle("This is my custom dialog box");
    dialog.setCancelable(true);
    // there are a lot of settings, for dialog, check them all out!
    // set up radiobutton
    RadioButton rd1 = (RadioButton) dialog.findViewById(R.id.rd_);
    RadioButton rd2 = (RadioButton) dialog.findViewById(R.id.rd_2);

    // now that the dialog is set up, it's time to show it
    dialog.show();
