compile 'com.contrarywind:Android-PickerView:3.2.7' androidStudio依赖,Eclipse可自行在github上搜索Android-PickerView项目添加依赖现git地址https://github.com/Bigkoo/Android-PickerView下面给出项目中自定义数据的联动菜单实现

二级菜单封装

三级时间菜单封装

public class BirthdayPickerShower {    private TimePickerView pvTime;    TextView tv;    Context context;    public BirthdayPickerShower(TextView textView, Context context) {        tv = textView;        this.context = context;        initTimePicker();    }    public  void show() {        pvTime.show(tv);    }    private void initTimePicker() {        //控制时间范围(如果不设置范围，则使用默认时间1900-2100年，此段代码可注释)        //因为系统Calendar的月份是从0-11的,所以如果是调用Calendar的set方法来设置时间,月份的范围也要是从0-11        Calendar selectedDate = Calendar.getInstance();        Calendar startDate = Calendar.getInstance();        startDate.set(1917, 0, 23);        Calendar endDate = Calendar.getInstance();        endDate.set(2018, 11, 28);        int color = context.getResources().getColor(R.color.maincolor);        //时间选择器        pvTime = new TimePickerView.Builder(context, new TimePickerView.OnTimeSelectListener() {            @Override            public void onTimeSelect(Date date, View v) {//选中事件回调                // 这里回调过来的v,就是show()方法里面所添加的 View 参数，如果show的时候没有添加参数，v则为null                TextView view = (TextView) v;                view.setText(getTime(date));            }        })                //年月日时分秒 的显示与否，不设置则默认全部显示                .setType(new boolean[]{true, true, true, false, false, false})                .setLabel("", "", "", "", "", "")                .isCenterLabel(false)                .setDividerColor(color)                .setTextColorCenter(color)                .setCancelColor(color)                .setSubmitColor(color)                .setSubmitText("完成")                .setContentSize(21)                .setDate(selectedDate)                .setRangDate(startDate, endDate)                .setDecorView(null)                .build();    }    private String getTime(Date date) {//可根据需要自行截取数据显示        SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd");        return format.format(date);    }}
实体bean,如果不需要标题不需要实现IPickerViewData ,我这里也没好好实现 因为发现我的效果不需要标题

public class LocalAreaBean implements IPickerViewData {    // 实现 IPickerViewData 接口，    // 这个用来显示在PickerView上面的字符串，    // PickerView会通过IPickerViewData获取getPickerViewText方法显示出来。    @Override    public String getPickerViewText() {        return this.name;

               }            }        }    }}

使用
1.实现接口
public class VerificationIdentityActivity extends BaseActivity implements LocationPickerShowerState.OnOptionsSelectListener, LocationPickerShowerLocal.OnLocalOptionsSelectListener
@Overridepublic void getAreaCode(String text, String areaCode) {    countryText = text;    liveDistrictTv.setText(countryText);    countyCode = areaCode;}/** * 现居村社选择完成回调方法 */@Overridepublic void getLocalAreaCode(String text, String areaCode) {    localText = text;    liveVillageTv.setText(localText);    localCode = areaCode;}

2.显示LocationPickerShowerState locationPickerShowerState;LocationPickerShowerLocal locationPickerShowerLocal;Handler mHandler = new Handler(new Handler.Callback() {    @Override    public boolean handleMessage(Message msg) {        switch (msg.what) {            case STATE:                locationPickerShowerState.show();                break;            case Local:                locationPickerShowerLocal.show();                break;        }        return false;    }});
