Just replace this code below with your button you want

         <Button
            android:id="@+id/buttonChatGlobal"
            android:layout_width="wrap_content"
            android:gravity="bottom"
            android:layout_height="wrap_content"
            android:background="#359c5e"
            android:padding="8dp"
            android:layout_margin="5dp"
            android:text="ChatGlobal"
            android:gravity="bottom|left"
            android:textColor="#ffffff" />
