在项目开发中Android基本都是在跟随ios的风格，前段时间产品经理就要求按照ios的效果，做时间、城市选择效果，真要全部自己写还真有点蛋疼，所以在网上一搜，效果不少，其中PickerView用的人还是蛮多的，所以就决定用PickerView来实现；
PickerView提供了：时间选择器和选项选择器
——TimePickerView 时间选择器，支持年月日时分，年月日，年月，时分等格式。
——OptionsPickerView 选项选择器，支持一，二，三级选项选择，并且可以设置是否联动 。
- 支持三级联动
- 设置是否联动
- 设置循环模式
- 支持自定义布局。
- 支持item的分隔线设置。
- 支持item间距设置。
- 时间选择器支持起始和终止日期设定。
- 支持“年，月，日，时，分，秒”，“省，市，区”等选项的单位（label）显示、隐藏和自定义。
- 支持自定义文字、颜色、文字大小等属性
- Item的文字长度过长时，文字会自适应缩放到Item的长度，避免显示不完全的问题
- 支持Dialog 模式。
- 支持自定义设置容器。
- 实时回调。
首先先将库依赖到自己的项目中；
compile 'com.contrarywind:Android-PickerView:4.1.6'先来看时间选择器，时间选择器涉及到TimePickerView和TimePickerBuilder，这里采用了链式编程和build设计模式；在TimePickerBuilder中提供了一系列调用设置的方法；
public class TimePickerBuilder {
private PickerOptions mPickerOptions;
//Required
public TimePickerBuilder(Context context, OnTimeSelectListener listener) {
mPickerOptions = new PickerOptions(PickerOptions.TYPE_PICKER_TIME);
mPickerOptions.context = context;

}在实例化时可以根据自己需要调用相应方法；先看下非自定义布局的实现；
/**

*/

pvTime = new TimePickerBuilder(this, new OnTimeSelectListener() {
@Override
public void onTimeSelect(Date date, View v) {
//选择回调
Toast.makeText(MainActivity.this,getTime(date),Toast.LENGTH_LONG).show();
}
})
.setTimeSelectChangeListener(new OnTimeSelectChangeListener() {
@Override
public void onTimeSelectChanged(Date date) {
//时间滚动监控回调
Log.e("pvTime-->",getTime(date));
}
})
.setType(new boolean[]{true, true, true, true, true, true,})
.isDialog(true)//默认设置false ，内部实现将DecorView 作为它的父控件。
.build();
Dialog dialog = pvTime.getDialog();
if(dialog!=null){
FrameLayout.LayoutParams params=new FrameLayout.LayoutParams(
ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.WRAP_CONTENT,
Gravity.BOTTOM
);
params.leftMargin=0;
params.rightMargin=0;
pvTime.getDialogContainerLayout().setLayoutParams(params);
Window dialogWindow = dialog.getWindow();
if(dialogWindow!=null){
//修改动画样式
dialogWindow.setWindowAnimations(com.bigkoo.pickerview.R.style.picker_view_slide_anim);
//改成Bottom,底部显示
dialogWindow.setGravity(Gravity.BOTTOM);
}
}
}调用上面这段代码，再调用show方法，效果就出来了；
公农历切换效果：

条件选择(不联动效果):
/**
* 不联动的多级选项
*/
private void initNoLinkOptionsPicker() {
pvNoLinkOptions = new OptionsPickerBuilder(this, new OnOptionsSelectListener() {
@Override
public void onOptionsSelect(int options1, int options2, int options3, View v) {
