Fragment切換動畫

FragmentTransaction ft = getSupportFragmentManager().beginTransaction();

//**************方法一，使用系統已定義動畫***************
// ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);//各個屬性含義請看FragmentTransaction中原始碼

//**************方法二，使用自定義動畫********************
ft.setCustomAnimations(R.anim.slide_in_alpha
 
, R.anim.slide_out_alpha);
ft.replace(containerViewId, newFragment).commit();
