2 günlük mücadeleden sonra bu soruna çalışan bir çözüm hazırladım, aşağıdaki çözüm sadece birkaç düzenleme metnini değiştirmek, java kodu ile rengi değiştirmek / değiştirmek ve işletim sistemi sürümlerinde farklı davranış sorunlarının üstesinden gelmek isteyenler için mükemmel setColorFilter () yöntemi kullanıldığından.
