Try like this.
You have set android:layout_marginLeft="280dp"
so replace this with
android:layout_marginLeft="20dp"
or something else
so basically your button's code will look something like this
<Button
android:id="@+id/next_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="20dp"
android:layout_marginLeft="20dp"
android:text="@string/create_card_next_button"
android:onClick="next"/>
I think you have set margin left to 280dp
which is causing problem and making it out of your screen set it to 20dp
or as per your screen requirement as you have set other and it should work.
