wheelview 省市区android

最近项目中用到wheelview效果，参考了大神Hongyang的实现思路，然后在github上merge了一个库，主要的工作是修复了各种异常情况下的bug

效果图：

ps:用到了一个json文件以及解析拼接我们需要的数据

json数据文件我已经放到压缩包里面了，我们通过读取assert中的json,拼接为三个list，来适配我们的view

主要代码如下：

1：初始化数据【解析json】

 private ArrayList<SdkProvinceBean> options1Items = new ArrayList<SdkProvinceBean>();
    private ArrayList<ArrayList<String>> options2Items = new ArrayList<ArrayList<String>>();
    private ArrayList<ArrayList<ArrayList<String>>> options3Items = new ArrayList<ArrayList<ArrayList<String>>>();
    OptionsPickerView pvOptions;

    private void pickViewInit() {

        try {

            String jsonStr = FileUtil.readJSONFileSDK(EPApp.mContext);
            SdkProvience mProvience = JSON.parseObject(jsonStr, SdkProvience.class);
            ArrayList<SdkCity> citylist = mProvience.getCitylist();
            //opt1
            for (int i = 0; i < citylist.size(); i++) {
                SdkCity currentCity = citylist.get(i);
                options1Items.add(new SdkProvinceBean(i, currentCity.getP(), "", ""));
                ArrayList<String> options2Items_ = new ArrayList<String>();
                ArrayList<ArrayList<String>> options3Items_01_0 = new ArrayList<ArrayList<String>>();
                for (int j=0;j<currentCity.getC().size();j++){
                    LogUtils.i("jone","size  "+currentCity.getC().size());
                    WeelC currentWeelC =  currentCity.getC().get(j);
                    options2Items_.add(currentWeelC.getN());
                    ArrayList<String> options3Items_01_1 = new ArrayList<String>();
                    if (currentWeelC.getA() != null){
                        for (int k=0;k<currentWeelC.getA().size();k++){
                            options3Items_01_1.add(currentWeelC.getA().get(k).getS());
                        }
                        options3Items_01_0.add(options3Items_01_1);
                    }

                }

                options2Items.add(options2Items_);
                options3Items.add(options3Items_01_0);
            }

        } catch (Exception e) {


        }

        //监听确定选择按钮
        pvOptions.setOnoptionsSelectListener(new OptionsPickerView.OnOptionsSelectListener() {

            @Override
            public void onOptionsSelect(int options1, int option2, int options3) {
                //返回的分别是三个级别的选中位置
                pvOptions.setDismis();
                StringBuffer stringBuffer = new StringBuffer();
                stringBuffer.append(options1Items.get(options1).getPickerViewText()
                        + options2Items.get(options1).get(option2));
                try {
                    stringBuffer.append(options3Items.get(options1).get(option2).get(options3));
                } catch (Exception e) {

                }


                ToastUtil.showMessage(getActivity(),stringBuffer.toString());

            }

            @Override
            public void onOptionsDismiss() {
                pvOptions.setDismis();
            }
        });
    }

2：展示pickView

  pvOptions.setPicker(options1Items, options2Items, options3Items, true);
                pvOptions.setTitle("选择城市");
                pvOptions.setCyclic(false, false, false);
                pvOptions.setSelectOptions(0, 1, 0);
                pvOptions.show();

附上解析json方法：

  public static String  readJSONFileSDK(Context context) {
        int len;
        byte buf[] = new byte[1024];
        InputStream inputStream;
        ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
        try {
            inputStream = context.getAssets().open("sdkarea.json");
             while ((len = inputStream.read(buf)) != -1) {
                outputStream.write(buf, 0, len);
            }
            jsonAera = new String(outputStream.toByteArray(), "UTF-8");
            outputStream.close();
            inputStream.close();
        } catch (Exception e) {
            LogUtils.e(TAG, "", e);
        }

        return  jsonAera;
    }
