activity 调用

1、实现接口

public class AddwcrrActivity extends BaseFragmentActivity implements TimePickerDia.TimePickerDialogInterface

2、实现方法

@Override
public void positiveListener() {//回调结果方法
    int hour = mTimePickerDialog.getHour();
    int minute = mTimePickerDialog.getMinute();
    int year = mTimePickerDialog.getYear();
    int month = mTimePickerDialog.getMonth();
    int day = mTimePickerDialog.getDay();
    wcsqrq.setText(year+"-"+month+"-"+day+" "+hour+":"+minute);
}

@Override
public void negativeListener() {

}

3、实例化工具类

private TimePickerDia mTimePickerDialog ;

mTimePickerDialog = new TimePickerDia(this);

4、点击调用

@OnClick({R.id.backliwc,R.id.wctijiao,R.id.wcsqrq})
public void onClick(View view) {
    switch (view.getId()) {
        case R.id.backliwc:
            onBackPressed();
            break;
        case R.id.wcsqrq:
            mTimePickerDialog.showDateAndTimePickerDialog();
            break;
