```

```java
//OptionsPicker
 pvOptions = new OptionsPickerBuilder(this, new OnOptionsSelectListener() {
            @Override
            public void onOptionsSelect(int options1, int option2, int options3 ,View v) {
                ////Callback
                String tx = options1Items.get(options1).getPickerViewText()
                        + options2Items.get(options1).get(option2)
                        + options3Items.get(options1).get(option2).get(options3).getPickerViewText();
                tvOptions.setText(tx);
            }
        }).build();

 //pvOptions.setPicker(options1Items);
 pvOptions.setPicker(options1Items, options2Items);
 //pvOptions.setPicker(options1Items, options2Items, options3Items);
 pvOptions.show();
```
## Just so easy ~


### Notes（2017-7-10）
- when we start setting the date, we need to pay special attention.

- reason: the internal component of the Calendar adds 1 processing, which made the month's number of  count reduced one.
- error usage case:

>StartDate.set (2013,1,1);

>EndDate.set (2020,12,31);

- correct use case:

>StartDate.set (2013,0,1);

>EndDate.set (2020,11,31);
</br>


If the default style does not meet your expectations, You can also customize attributes to apply

## Customize Useage：
```java
 Calendar selectedDate = Calendar.getInstance();
 Calendar startDate = Calendar.getInstance();
 startDate.set(2013,0,1);
 Calendar endDate = Calendar.getInstance();
 endDate.set(2020,11,1);

 pvTime = new TimePickerBuilder(this, new OnTimeSelectListener() {
            @Override
            public void onTimeSelect(Date date,View v) {//callback
                tvTime.setText(getTime(date));
            }
        })
                .setType(new boolean[]{false, false, false, true, true, false})// type of date 
                .setCancelText("Cancel")
                .setSubmitText("Sure")
                .setContentSize(18)
                .setTitleSize(20)
                .setTitleText("Title")
                .setOutSideCancelable(false)// default is true
                .isCyclic(true)// default is false
                .setTitleColor(Color.BLACK)
                .setSubmitColor(Color.BLUE)
                .setCancelColor(Color.BLUE)
                .setTitleBgColor(0xFF666666)//night mode
                .setBgColor(0xFF333333)//night mode
                .setRangDate(startDate,endDate)
                .setLabel("year","month","day","hours","mins","seconds")
                .build();
```

```java
pvOptions = new OptionsPickerBuilder(this, new OnOptionsSelectListener() {
            @Override
            public void onOptionsSelect(int options1, int option2, int options3 ,View v) {
                ////Callback
                String tx = options1Items.get(options1).getPickerViewText()
                        + options2Items.get(options1).get(option2)
                        + options3Items.get(options1).get(option2).get(options3).getPickerViewText();
                tvOptions.setText(tx);
            }
        })
                .setSubmitText("sure")
                .setCancelText("cancel")
                .setTitleText("title")
                .setSubCalSize(18)
                .setTitleSize(20)
                .setTitleColor(Color.BLACK)
                .setSubmitColor(Color.BLUE)
                .setCancelColor(Color.BLUE)
                .setTitleBgColor(0xFF666666)//night mode
                .setBgColor(0xFF444444)//night mode
                .setContentTextSize(18)
                .setLinkage(false)
                .isCenterLabel(false) //default is true , if you choose false , the label text will add to all item ContentText right
                .setLabels("province", "city", "district")
                .setCyclic(false, false, false)
                .setSelectOptions(0, 0, 0)  //default options
                .setOutSideCancelable(false)//dismiss， default is true
                .isRestoreItem(true)// restore option with first item when select changed。
                .build();

        pvOptions.setPicker(options1Items, options2Items, options3Items);
```
## Customize Layout：
```java
  private void initCustomTimePicker() {
        // be careful：In the custom layout， the layout of the ID for optionspicker
        // or TimePicker and its child widget must not be modified,
        // otherwise  will be reported NullPointerException
        // For more details， Please refer to the two custom layouts in demo

        Calendar selectedDate = Calendar.getInstance();//System current time
        Calendar startDate = Calendar.getInstance();
        startDate.set(2013,1,23);
        Calendar endDate = Calendar.getInstance();
        endDate.set(2019,2,28);

        pvCustomTime = new TimePickerBuilder(this, new OnTimeSelectListener() {
            @Override
            public void onTimeSelect(Date date, View v) {//call back
                btn_CustomTime.setText(getTime(date));
            }
        })       .setType(new boolean[]{true, true, true, false, false, false})// year - month - day
                .setDate(selectedDate)
                .setRangDate(startDate,endDate)
                .setLayoutRes(R.layout.pickerview_custom_time, new CustomListener() {

                    @Override
                    public void customLayout(View v) {
                        final TextView tvSubmit = (TextView) v.findViewById(R.id.tv_finish);
                        ImageView ivCancel = (ImageView) v.findViewById(R.id.iv_cancel);
                        tvSubmit.setOnClickListener(new View.OnClickListener() {
                            @Override
                            public void onClick(View v) {
                                pvCustomTime.returnData(tvSubmit);
                            }
                        });
                        ivCancel.setOnClickListener(new View.OnClickListener() {
                            @Override
                            public void onClick(View v) {
                                pvCustomTime.dismiss();
                            }
                        });
                    }
                })
                .setDividerColor(Color.BLACK)
                .build();

    }
```

## If you need to set the non-linkage data：

```java
pvNoLinkOptions = new OptionsPickerBuilder(this, new OnOptionsSelectListener() {

            @Override
            public void onOptionsSelect(int options1, int options2, int options3, View v) {

                String str = "food:"+food.get(options1)
                        +"\nclothes:"+clothes.get(options2)
                        +"\ncomputer:"+computer.get(options3);

                Toast.makeText(MainActivity.this,str,Toast.LENGTH_SHORT).show();
            }
        }).build();
        pvNoLinkOptions.setNPicker(food,clothes,computer);
        pvNoLinkOptions.show();
```
