Fragment切換

    / 
     Fragment切換 
    @Params toFragment 將要切換到的Fragment 
            resId      裝載Fragment的view Id 
            index      Fragment的標識index 
            toleft     判斷Fragment向左切換還是向右切換，以采用不同的動畫 
    Notes:  R.anim.push_left_in等均為簡單的Tranlate動畫 
            mCurrentFragment為當前所在的Fragment，繼承自BaseFragment
