Java kodunu ve xml'sini ve ekran görüntüsünü ekliyorum. tablayout.java, tablaout.xml dosyasını eklediğim sınıftır ve ekranın altındaki sekmeyi hizaladığım zaman, düzenin en üstünde yer alan alanın bir kısmı boşa gider.Düzenin sonundaki sekme düzenini hizaladığımda, düzenimin üst kısmında sola bir boşluk kalıyor
