Snackbar 與回撥

你可以使用 Snackbar.Callback 來監聽快餐欄是否被使用者解僱或超時。

Snackbar.make(getView(), "Hi snackbar!", Snackbar.LENGTH_LONG).setCallback( new Snackbar.Callback() {
                @Override
                public void onDismissed(Snackbar snackbar, int event) {
                    switch(event) {
                        case Snackbar.Callback.DISMISS_EVENT_ACTION:
                            Toast.makeText(getActivity(), "Clicked the action", Toast.LENGTH_LONG).show();
                            break;
                        case Snackbar.Callback.DISMISS_EVENT_TIMEOUT:
                            Toast.makeText(getActivity(), "Time out", Toast.LENGTH_LONG).show();
                            break;
                    }
                }

                @Override
                public void onShown(Snackbar snackbar) {
                    Toast.makeText(getActivity(), "This is my annoying step-brother", Toast.LENGTH_LONG).show();
                }
            }).setAction("Go!", new View.OnClickListener() {
                @Override
                public void onClick(View v) {

                }
            }).show();
