使用本FragmentTransaction FM = getActivity（ ）.getSupportF 。ragmentManager（）的BeginTransaction（）; – Palak
@Palak我試過這種方式FragmentTransaction fm =（（MainActivity）getActivity（））。getSupportFragmentManager（）。beginTransaction（）; 但即時獲取錯誤爲 ype不匹配：無法從android.support.v4.app.FragmentTransaction轉換爲android.app.FragmentTransaction – VenushkaT
import android.app.FragmentTransaction; n將此替換爲導入android.support.v4.app。 FragmentTransaction; – Palak
