开发中仿IOS三级菜单,开源项目Android-PickerView实用自定义数据封装使用实例
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

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;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;

使用
1.实现接口
public class VerificationIdentityActivity extends BaseActivity implements LocationPickerShowerState.OnOptionsSelectListener, LocationPickerShowerLocal.OnLocalOptionsSelectListener
@Override
public 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
*/
@Override
public 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; } });
