安卓原生时间选择器，DatePicker和TimePicker并用，弹窗dialog

封装安卓原生时间选择器，DatePicker和TimePicker并用，弹窗dialog，用起来非常方便...

之前写的用起来麻烦，这回又优化了一下，有什么不对或是更简单的办法大家可评论....

看效果（看见不好看自己修修）：

dialog布局：

这是datePicker和timePicker同时显示的时候的布局(这个是横向的适配可能不是很)，其他两个没有就不贴了，自己建一个布局写个DatePicker或TimePicker，再或者写在一个布局自己判断调用...

这个是纵向的适配会非常容易，推荐使用。

使用方法很简单：

1.new出来在activity或fragment定义成全局的变量。

  mTimePickerDialog = new TimePickerDialog(RouteSetOwnerActivity.this);

2.就像这样想显示那个显示那个。

 mTimePickerDialog.showTimePickerDialog();

3.现实TImePickerDialog里面接口，并且重写里面的方法，然后根据自己的 需要来取时间。如下：

public class RouteSetOwnerActivity extends Activity implements TimePickerDialog.TimePickerDialogInterface {
 
   
    private TimePickerDialog mTimePickerDialog;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_route_set_owner);
        mTimePickerDialog = new TimePickerDialog(RouteSetOwnerActivity.this);
      
      
    }

    //时间选择器----------确定
    @Override
    public void positiveListener() {
        int hour = mTimePickerDialog.getHour();
        int minute = mTimePickerDialog.getMinute();
        Log.i("=====","=======year======"+mTimePickerDialog.getYear());
        Log.i("=====","=======getMonth======"+mTimePickerDialog.getMonth());
        Log.i("=====","=======getDay======"+mTimePickerDialog.getDay());
        Log.i("=====","=======getHour======"+mTimePickerDialog.getHour());
        Log.i("=====","=======getMinute======"+mTimePickerDialog.getMinute());
        mTv_getOffWork.setText(hour+":"+minute);
    }

    //时间选择器-------取消
    @Override
    public void negativeListener() {

    }
}
