                    public void onClick(DialogInterface dialog,int id) {
                        // if this button is clicked, close
                        // current activity

                        Log.d("TAG","button inside sdCard");
                        AlarmActivity.this.finish();
                    }
                  });
                 alertDialogBuilder.show();

Try this..

Change this..

AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(
                        getApplicationContext());

to

AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(
                        AlarmActivity.this);

EDIT

radio_btn.xml

<?xml version="1.0" encoding="UTF-8"?>
<RadioGroup xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/status_group"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_margin="5dp"
    android:orientation="vertical" >

    <RadioButton
        android:id="@+id/default_btn"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Default music" />

    <RadioButton
        android:id="@+id/external_btn"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="External card music" />

</RadioGroup>

JAVa

    LayoutInflater inflater = getLayoutInflater();
    View dialoglayout = inflater.inflate(R.layout.radio_btn, (ViewGroup) getCurrentFocus());
    RadioButton default_btn = (RadioButton) dialoglayout.findViewById(R.id.default_btn);
    RadioButton external_btn = (RadioButton) dialoglayout.findViewById(R.id.external_btn);
    AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(
                        AlarmActivity.this);
                Log.d("TAG","button inside mobile");
                alertDialogBuilder
                //.setMessage("Click yes to exit!")
                .setCancelable(false)
                .setView(dialoglayout);
                .setPositiveButton("OK",new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog,int id) {
                        // if this button is clicked, close
                        // current activity
                        AlarmActivity.this.finish();
                    }
                  });
                 alertDialogBuilder.show();

Use AlarmActivity.this or this intead of getApplicationContext().

Create in layout in res/layout

radio_dialog_layout.xml

<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>

create dialog in activity by using this code:

Dialog dialog = new Dialog(this);
dialog.setContentView(R.layout.radio_dialog_layout);
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();

Create one xml file,

 <RadioButton
    android:id="@+id/radiobutton1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Hi" />

<RadioButton
    android:id="@+id/radiobutton2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_below="@+id/radiobutton1"
    android:text="Bye" />

<Button
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_below="@+id/radiobutton2"
    android:layout_centerInParent="true"
    android:text="Click" />

and create Dialog in activity,

Dialog dialog = new Dialog(MainActivity.this);
    dialog.setContentView(R.layout.activity_main);
    dialog.setTitle("My Dialog Box");
    dialog.setCancelable(true);

    // set up radiobutton inside dialog box
    RadioButton rb1 = (RadioButton) dialog.findViewById(R.id.radiobutton1);
    RadioButton rb2 = (RadioButton) dialog.findViewById(R.id.radiobutton2);

    // Show the dialog
    dialog.show();
