Android:从接口获取值

将此添加到活动中:

    //Use below variables to set values and access them inside your activity    
        private int hour;
        private int minute;


        @Override
        public void setTime(int hour, int minute){
        Log.i("hour",hour);
       //You can use hour minute value here like setting text to textview etc or set them to instance variable for further use

        this.hour = hour;
        this.minute = minute;
        }

您可能会出错,因为您的参数类型不对 Log 打电话。而不是这样:

Log.i("hour", hour);

Log.i("hour", String.valueOf(hour));

这是因为 日志 需要一个 String 作为参数,而不是 int .
