Fragment跳转无效

出错代码

                        Intent intent = new Intent(mActivity, MainActivity.class);                        intent.putExtra(Constants.MAIN_TYPE,                         RechargeFragment.class.getSimpleName());                        mActivity.startActivity(intent);                        //发现根本跳不过去

正确代码

                        Intent intent = new Intent(mActivity, MainActivity.class);                        intent.putExtra(Constants.MAIN_TYPE,                         RechargeFragment.class.getSimpleName());                        mActivity.startActivity(intent);                        mActivity.finish();//其实已经跳过去了，只是当前Activity没有finish
