不兼容的類型：活動無法轉換為 OnDateSetListener

Question

錯誤：類型不兼容：FragmentActivity 無法轉換為 OnDateSetListener.callback(getActivity())

new SpinnerDatePickerDialogBuilder()
            .context(getActivity())
            .callback(getActivity())
            .spinnerTheme(R.style.NumberPickerStyle)
            .showTitle(true)
            .showDaySpinner(true)
            .defaultDate(2000, 0, 1)
            .maxDate(Integer.parseInt(temp), 0, 1)
            .minDate(1950, 0, 1)
            .build()
            .show();

您的片段必須實現接口 OnDateSetListener 並設置
SpinnerDatePickerDialogBuilder

new SpinnerDatePickerDialogBuilder()
            .context(getActivity())
            .callback(this)
            .spinnerTheme(R.style.NumberPickerStyle)
            .showTitle(true)
            .showDaySpinner(true)
            .defaultDate(2000, 0, 1)
            .maxDate(Integer.parseInt(temp), 0, 1)
            .minDate(1950, 0, 1)
            .build()
            .show();
