android开发之DatePickerDialog与TimePickerDialog的使用

通过对话框的形式，来进行选择。尤其感觉DatePickerDialog比DatePicker在用户选择交互时好的多.

DatePickerDialog与TimePickerDialog都进行了很好的封装，对于开发者来说，直接调用，非常的简单。

演示实例：

public class MainActivity extends Activity {

	Button button,button2;

	@Override
	public void onCreate(Bundle savedInstanceState) {

		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);

	}

	public void dateClick(View v) {

		Calendar calendar = Calendar.getInstance();

		DatePickerDialog datePickerDialog = new DatePickerDialog(
				MainActivity.this, new OnDateSetListener() {

					@Override
					public void onDateSet(DatePicker arg0, int year,
							int monthOfYear, int dayOfMonth) {

						//做你想做的事情

					}
				}, calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH),
				calendar.get(Calendar.DAY_OF_MONTH));
		datePickerDialog.show();

	}

	public void timeClick(View v){

		Calendar calendar = Calendar.getInstance();
		TimePickerDialog dialog = new TimePickerDialog(MainActivity.this, new OnTimeSetListener() {

			@Override
			public void onTimeSet(TimePicker arg0, int arg1, int arg2) {
				//做你想做的事情

			}
		}, calendar.get(Calendar.HOUR_OF_DAY), calendar.get(Calendar.MINUTE), true);

		dialog.show();
	}

}
