Número de Diálogos Personalizados (Selecionador de Data e Hora) com relação aos Botões de Rádio
Eu tenho um grupo de botões de rádio, como mostrado no botão de código abaixo. Quando eu clico em cada botão de rádio, eu quero um diálogo diferente, como mostrado na imagem abaixo. Um para cada botão de rádio. Estes devem estar em caixas de diálogo. Como eu faço isso?No final Tudo que eu preciso é gerar esses Diálogos Personalizados. Alguém pode me ajudar como eu posso fazer isso?
Também estou recebendo uma exceção de ponteiro nulo. Como resolvo?
