android-时间选择器

参考网站：http://wear.techbrood.com/guide/topics/ui/controls/pickers.html

1、首先定义一个类DatePickerFragment继承DialogFragment，并实现接口DatePickerDialog.OnDateSetListener；

/**
 * Created by czz on 2016/4/1.
 */
public class DatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener{

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {

        final Calendar calendar = Calendar.getInstance();
        int year = calendar.get(Calendar.YEAR);
        int month = calendar.get(Calendar.MONTH);
        int day = calendar.get(Calendar.DAY_OF_MONTH);

        return new DatePickerDialog(getActivity(),this,year,month, day);
    }

    @Override
    public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
        Toast.makeText(getActivity(),year+"/" + monthOfYear + "/" + dayOfMonth,Toast.LENGTH_SHORT).show();
    }
}

2、布局一个按钮或其他控件

<Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="时间选择器"
        android:id="@+id/id_selectTime"
        android:layout_below="@+id/id_togglebtn"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:layout_marginTop="43dp" />

3、声明 DialogFragment对象，调用show()方法

        selectTime = (Button) findViewById(R.id.id_selectTime);
        selectTime.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                DialogFragment TimeDF = new DatePickerFragment();
                TimeDF.show(getFragmentManager(),"datePicker");
            }
        });
