每日总结

1.今天继续学习Date & Time组件

DatePicker(日期选择器)：

代码实现：

DatePicker dp_test = (DatePicker) findViewById(R.id.dp_test);
        Calendar calendar = Calendar.getInstance();
        int year=calendar.get(Calendar.YEAR);
        int monthOfYear=calendar.get(Calendar.MONTH);
        int dayOfMonth=calendar.get(Calendar.DAY_OF_MONTH);
        dp_test.init(year,monthOfYear,dayOfMonth,this);
    }

    @Override
    public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
        Toast.makeText(MainActivity.this,"您选择的日期是："+year+"年"+(monthOfYear+1)+"月"+dayOfMonth+"日!",Toast.LENGTH_SHORT).show();
    }
