在行 ::

android.support.v4.app.FragmentTransaction ft = getSupportFragmentManager().beginTransaction().replace(R.id.frame_container, fragment).commit(); 

我得到錯誤的 ::

The method getSupportFragmentManager() is undefined for the type MainActivity 

Answer 1

你應該擴大，而不是SherlockActivity

Answer 2

使用getActivity SherlockFragmentActivity（ ）.getSupportFragmentManager（） insted getSupportFragmentManager（）。

這是工作。
