    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        ButterKnife.bind( this );
        intiPickerView();
    }

    private  void intiPickerView(){
        //一级列表
        ProvinceBean provinceBean = new ProvinceBean();
        mProvinceDatas.addAll(provinceBean.getRepData().getProvince());

        //二级列表
        SecondBean secondBean = new SecondBean();
        mSecondDatas.putAll(secondBean.getRepData().getSecond());

        //三级列表
        ThirdBean thirdBean = new ThirdBean();
        mThirdDatas.putAll(thirdBean.getRepData().getThird());

        Log.i("json", JsonArrayUtil.toJson(mProvinceDatas));
        Log.i("json",JsonArrayUtil.toJson(mSecondDatas));
        Log.i("json",JsonArrayUtil.toJson(mThirdDatas));

        //设置数据有多少层级
        PickerData data=new PickerData();
        data.setFirstDatas(mProvinceDatas);//json: ["广东","江西"]
        data.setSecondDatas(mSecondDatas);//json: {"江西":["南昌","赣州"],"广东":["广州","深圳","佛山","东莞"]}
        data.setThirdDatas(mThirdDatas);//json: {"广州":["天河区","白云区","番禹区","花都区"],"赣州":["章贡区","黄金开发区"],"东莞":["东城","南城"],"深圳":["南山区","宝安区","龙华区"],"佛山":["禅城区","顺德区"],"南昌":["东湖区","青云谱区","青山湖区"]}

        data.setInitSelectText("请选择");

        TeaPickerView teaPickerView =new TeaPickerView(this,data);
        teaPickerView.setScreenH(3)
                .setDiscolourHook(true)

                .build();

        button.setOnClickListener(v -> {
            //显示选择器
            teaPickerView.show(button);
        });

        //选择器点击事件
        teaPickerView.setOnPickerClickListener(pickerData -> {
            Toast.makeText(MainActivity.this,pickerData.getFirstText()+","+pickerData.getSecondText()+","+pickerData.getThirdText(),Toast.LENGTH_SHORT).show();
            teaPickerView.dismiss();//关闭选择器
        });
    }
