Re: [androidbrasil-dev] Como pegar conteúdo de um TextView que está em um Fragment

Estou usando um mesmo Fragment... eu só atualizo um TextView dentro dele, quando chegar em casa eu posto a View dele.

Ela está dentro de um PagerAdapter.

Sobre o botão salvar, não sei qual o foco da tua aplicação mas recomendo a leitura do post que o Bruno Oliveira (do Google) fez no ano passado sobre esse tipo de prática:

Sobre o erro: por um acaso tu não estas com dois fragments utilizando o mesmo id ou algo do tipo?

Cara, pra descontrair, compartilhando um pensamento meu aqui, esses
logs de debug tão parecendo oração!

Rachei o bico com os será aqui! Sem querer julgar nem nada pois já
sofri da mesma maneira.

Infelizmente não tenho como ajudar, mas, essa valeu a semana...

Pode ser pura bobeira minha mas rachei o bico com isso, acho que ando
estressado demais!

Abraço!
