Firstly, you have to keep focus of any one of items (i.e. Button, TextView, etc.) as below. And also, you have to apply it's nextFocusDown, nextFocusLeft, nextFocusRight & nextFocusUp properties. So it will fire it's releveant event when you click TV remote navigation buttons.

Add request focus to your edit text like this,

<EditText
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:id="@+id/bTextUrl"
   android:layout_alignParentTop="true"
   android:layout_alignParentStart="true"
   android:layout_alignParentEnd="true"
   android:background="#faf6f6"
   android:layout_marginTop="60dp"
   android:nextFocusDown="@+id/bSendUrl">

   <requestFocus></requestFocus>
</EditText>   

<Button
   android:layout_width="@dimen/latimea_button_send_tv"
   android:layout_height="@dimen/inaltimea_button_send_tv"
   android:text="@string/button_send_android_tv"
   android:id="@+id/bSendUrl"
   android:background="@drawable/button_send_tv"
   android:layout_below="@+id/bTextUrl"
   android:layout_alignParentStart="true"
   android:layout_marginTop="35dp" />
</Button>

And after that, you can add more properties like nextFocusDown, nextFocusLeft, nextFocusRight, nextFocusUp to focus next item.
