Problem 1 how to create custom RadioButton ?

Answer: you can apply the custom style to your RedioButton. now there are very simple way to create custom style for a UI control. Here I show you how to crate custom style for RedioButton:

<style name="MyRadioButtonStyle" parent="@android:style/Widget.CompoundButton.RadioButton">
<item name="android:button">@drawable/custom_btn_radio</item>

create a drawble selector for the button state. res/drawable/custom_btn_radio.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="true" android:state_window_focused="false"
      android:drawable="@drawable/btn_radio_on" />
<item android:state_checked="false" android:state_window_focused="false"
      android:drawable="@drawable/btn_radio_off" />

<item android:state_checked="true" android:state_pressed="true"
      android:drawable="@drawable/btn_radio_on_pressed" />
<item android:state_checked="false" android:state_pressed="true"
      android:drawable="@drawable/btn_radio_off_pressed" />

<item android:state_checked="true" android:state_focused="true"
      android:drawable="@drawable/btn_radio_on_selected" />
<item android:state_checked="false" android:state_focused="true"
      android:drawable="@drawable/btn_radio_off_selected" />

<item android:state_checked="false" android:drawable="@drawable/btn_radio_off" />
<item android:state_checked="true" android:drawable="@drawable/btn_radio_on" />

Problem 2 How to show Two activity in a single Container(Perhaps It is also be a part of Activity) Answer : There are no way to open Activities in a single Activity class. You can open multiple Fragment in a single Activity. or Other way replace your layout at runtime on radio button selection. As i know First one is good way.
