:

mPosition++; 
max = mProgressBar.getMax(); 
mProgressBar.setProgress(mPosition); 
mStatus.setText(String.valueOf(max)); // here, just to test stuff! 

는 다음과 같은 예외와 함께 제공 :

mPosition++; 
max = mProgressBar.getMax(); 
mProgressBar.setProgress(mPosition); 

가 나는 TextView.setText() 추가하는 경우 :이 부분에 나타났습니다? 또는 더 나은 방법은 ProgressView 대신 TextView을 사용하도록 문서 예제를 조정하는 방법입니다.

Answer 1

다른 UI 스레드가 다시 호출되어 Fragment을 보유 할 수 있습니다. getActivity().runOnUIThread(some code)으로 해결할 수 있습니다. 그냥 내 제안.
