</LinearLayout>对话框类：
public class ChooseDate extends DialogFragment implementsView.OnClickListener{
private DatePicker datePicker;
private Button acceptButton;
private boolean isDateSetted = false;
private int year;
private int month;
private int day;
private DateListener listener;
public interface DateListener {
onDateSelected(int year, int month, int day);
}
public ChooseDate(){}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.dialog_year_picker, container);
getDialog().setTitle(getResources().getString("TITLE"));
datePicker = (DatePicker) rootView.findViewById(R.id.datePicker);
acceptButton = (Button) rootView.findViewById(R.id.buttonAccept);
acceptButton.setOnClickListener(this);
if (isDateSetted) {
datePicker.updateDate(year, month, day);
}
return rootView;
}
@Override
public void onClick(View v) {
switch(v.getId()){
case R.id.buttonAccept:
int year = datePicker.getYear();
int month = datePicker.getMonth() + 1; //个月从0开始
int day = datePicker.getDayOfMonth();
listener.onDateSelected(year, month, day);
break;
}
this.dismiss();
}
@Override
public void onAttach(Context context) {
super.onAttach(context);
listener = (DateListener) context;
}
public void setDate(int year, int month, int day) {
this.year= year;
this.month= month;
this.day= day;
this.isDateSetted= true;
}
}活动调用对话框：
public class MainActivity extends AppCompatActivity implements ChooseDate.DateListener{
private int year;
private int month;
private int day;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
private void showDateDialog();
}
private void showDateDialog(){
ChooseDate pickDialog = new ChooseDate();
//我们可以设定一个日期
//pickDialog.setDate(23,10,2016);
pickDialog.show(getFragmentManager(), "");
}
@Override
onDateSelected(int year, int month, int day){
this.day= day;
this.month= month;
this.year= year;
}
}
