2017最新详解Android中对话框之DatePickerDialog与TimePickerDialog

Date/TimePickerDialog只是供用户来选择日期时间,对于android系统的系统时间, 日期没有任何影响

他们两个的构造方法非常相似： DatePickerDialog(上下文；DatePickerDialog.OnDateSetListener()监听器；年；月；日)
TimePickerDialog(上下文；TimePickerDialog.OnTimeSetListener()监听器；小时，分钟，是否采用24小时制)

public class MainActivity extendsAppCompatActivity implementsView.OnClickListener{

  privateButton btn_date;

  privateButton btn_time;

  privateString result = "";

  @Override

  protectedvoid onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_main);

    bindViews();

  }

  privatevoid bindViews() {

    btn_date = (Button) findViewById(R.id.btn_date);

    btn_time = (Button) findViewById(R.id.btn_time);

    btn_date.setOnClickListener(this);

    btn_time.setOnClickListener(this);

  }

  @Override

  publicvoid onClick(View v) {

    result ="";

    switch(v.getId()){

      caseR.id.btn_date:

        Calendar cale1 = Calendar.getInstance();

        newDatePickerDialog(MainActivity.this,newDatePickerDialog.OnDateSetListener() {

          @Override

          publicvoid onDateSet(DatePicker view,int year, int monthOfYear,

                     intdayOfMonth) {

            //这里获取到的月份需要加上1哦~

            result +="你选择的是"+year+"年"+(monthOfYear+1)+"月"+dayOfMonth+"日";

            Toast.makeText(getApplicationContext(), result, Toast.LENGTH_SHORT).show();

          }

        }

            ,cale1.get(Calendar.YEAR)

            ,cale1.get(Calendar.MONTH)

            ,cale1.get(Calendar.DAY_OF_MONTH)).show();

        break;

      caseR.id.btn_time:

        Calendar cale2 = Calendar.getInstance();

        newTimePickerDialog(MainActivity.this,new TimePickerDialog.OnTimeSetListener() {

          @Override

          publicvoid onTimeSet(TimePicker view,int hourOfDay, int minute) {

            result ="";

            result +="您选择的时间是:"+hourOfDay+"时"+minute+"分";

            Toast.makeText(getApplicationContext(), result, Toast.LENGTH_SHORT).show();

          }

        }, cale2.get(Calendar.HOUR_OF_DAY), cale2.get(Calendar.MINUTE),true).show();

        break;

    }

  }

}
