Şimdiden yardımlarınız için teşekkürler..

https://www.import.io/ sitesini çoğu geliştirici bilir sanırım https://www.kimonolabs.com/ un alternatifi diyebiliriz kimono ekibi Plantire katıldığı için Palantir tarafından satın alındığı için kapatıldı orda webden veri alıp api haline getirip androidde kullanmak çok kolaydı fakat ücretsiz ve güzel bir hizmet olan import.io da oluşturduğum apinin androidde nasıl kullanılacağını bir türlü bulamadım arkadaşlar anlayan bilen yapabilen varsa bu konuda yardımcı olursa çok sevinirim..

Merhabalar,
Ben geliştirdiğim uygulamada Mail Gönderme activity içerisinde kullandığım T.C Kimlik No: …….. text viewini Validate yani doğrulamak istiyorum. Bunun için sayfa activity içerisinde iki AsyncTask kullanmak zorunda kaldım biri Maili göndermek diğeride Tc kimlik sorgusunu yapıyor Geçerli yada Geçersiz olma durumunu sorguluyor. Xml kısmında ise aynı aktivity içersinde kullandığım için text viewlerin ıd lerini eşleştirdim mesela mail için ad soyad gerekirken aynı şekilde tc sorgulamak için de ad soyad gerekti ben ikisini aynı id değerinde yaparak hem gmailime kişinin ad soyadını gönderyorum hemde tc sorgulamasını yaptıryorum şimdi sorun şu ki; Ben bu activity de önce tc sorgusunun yapılmasını geçersiz yada sallamasyon bir Tc girilmişse gelen “Geçersiz Tc No”  uyarısına göre mailinde gönderilmemesini istiyorum. En kısaca olaraktan doğru tc no girmemişse mailde gönderememesini istiyorum bunu nasıl yaparım?

Bu resimdeki sol üst köşedeki float action buttonu projemde kullandım buraya kadar herşey güzel yalnız ben o papatya yapraklarına benziyen menü elemanlarının herbirine ayrı birer activity atamak istiyorum bu mümkün mü? Mümkünse bunu nasıl yapabilirim yani bir activitye nasıl bağlantı verebilirim? Aşağıda kod parçacığımı gönderdim nasıl bir ekleme yapılması gerekiyor yardımcı olan olursa çok sevinirim.
