安装

“app”是 Sample；“android-pickers”是 library 包括 WheelPicker、SinglePicker、DatePicker、TimePicker、LinkagePicker、AddressPicker、NumberPicker、CarNumberPicker 等。

demo 下载

点我

远程加载 JitPack 包

加载的仓库： 第一步，在项目根目录下的 build.gradle 里添加 maven { url "https://jitpack.io" }引用：

allprojects {
    repositories {
        maven { url "https://jitpack.io" }//必须添加这行
    }
}

第二步，在项目的 app 模块下的 build.gradle 里加：

dependencies {
    implementation  'com.github.addappcn:android-pickers:2.0.0'
}

ProGuard

由于地址选择器使用了fastjson来解析，混淆时候需要加入以下类似的规则，不混淆 Province、City 等实体类。

-keepattributes InnerClasses,Signature
-keepattributes *Annotation*

-keep class cn.addapp.pickers.entity.** { *;}

注意事项

1. 联动设置对时间，地址选择器无效，加这个只是针对不需要联动的数据,如不满足你的开发需求 请自定义 picker。

Sample （具体用法详见 demo 项目）

继承自定义扩展选择器：

       CustomPicker picker = new CustomPicker(this);
               picker.setOffset(1);//显示的条目的偏移量，条数为（offset*2+1）
               picker.setGravity(Gravity.CENTER);//居中
               picker.setOnItemPickListener(new OnItemPickListener<String>() {
                   @Override
                   public void onItemPicked(int position, String option) {
                       showToast("index=" + position + ", item=" + option);
                   }
               });
               picker.show();

内嵌视图选择器：

        final TextView textView = findView(R.id.wheelview_tips);
                WheelListView wheelListView = findView(R.id.wheelview_single);
                wheelListView.setItems(new String[]{"少数民族", "贵州穿青人", "不在 56 个少数民族之列", "第 57 个民族"}, 1);
                wheelListView.setSelectedTextColor(0xFFFF00FF);
                LineConfig config = new LineConfig();
                config.setColor(Color.parseColor("#26A1B0"));//线颜色
                config.setAlpha(100);//线透明度
                config.setThick(ConvertUtils.toPx(this, 3));//线粗
                wheelListView.setLineConfig(config);
                wheelListView.setOnWheelChangeListener(new WheelListView.OnWheelChangeListener() {
                    @Override
                    public void onItemSelected(boolean isUserScroll, int index, String item) {
                        textView.setText("index=" + index + ",item=" + item);
                    }
                });
                picker = new CarNumberPicker(this);
                picker.setWeightEnable(true);
                picker.setColumnWeight(0.5f,0.5f,1);
                picker.setWheelModeEnable(true);
                picker.setTextSize(18);
                picker.setSelectedTextColor(0xFF279BAA);//前四位值是透明度
                picker.setUnSelectedTextColor(0xFF999999);
                picker.setCanLoop(true);
                picker.setOffset(3);
                picker.setOnMoreItemPickListener(new OnMoreItemPickListener<String>() {
                    @Override
                    public void onItemPicked(String s1, String s2, String s3) {
                        s3 = !TextUtils.isEmpty(s3) ? ",item3: "+s3 : "";
                        Toast.makeText(NextActivity.this, "item1: "+s1 +",item2: "+s2+ s3, Toast.LENGTH_SHORT).show();
                    }
                });
                picker.setOnMoreWheelListener(new OnMoreWheelListener() {
                    @Override
                    public void onFirstWheeled(int index, String item) {
                        textView.setText(item + ":" + picker.getSelectedSecondItem());
                    }
                    @Override
                    public void onSecondWheeled(int index, String item) {
                        textView.setText(picker.getSelectedFirstItem() + ":" + item);
                    }
                    @Override
                    public void onThirdWheeled(int index, String item) {
                    }
                } );
                ViewGroup viewGroup = findView(R.id.wheelview_container);
                viewGroup.addView(picker.getContentView());

选择器各个设置项：

        boolean isChinese = Locale.getDefault().getDisplayLanguage().contains("中文");
        OptionPicker picker = new OptionPicker(this,
                isChinese ? new String[]{
                        "水瓶", "双鱼", "白羊", "金牛", "双子", "巨蟹",
                        "狮子", "处女", "天秤", "天蝎", "射手", "摩羯"
                } : new String[]{
                        "Aquarius", "Pisces", "Aries", "Taurus", "Gemini", "Cancer",
                        "Leo", "Virgo", "Libra", "Scorpio", "Sagittarius", "Capricorn"
                });
        picker.setLabel(isChinese ? "座" : "");
        picker.setCycleDisable(true);//禁用循环
        picker.setLineConfig(config);
        picker.setTopHeight(50);//顶部标题栏高度
        picker.setTopLineColor(0xFF33B5E5);//顶部标题栏下划线颜色
        picker.setTopLineHeight(1);//顶部标题栏下划线高度
        picker.setTitleText(isChinese ? "请选择" : "Please pick");
        picker.setTitleTextColor(0xFF999999);//顶部标题颜色
        picker.setTitleTextSize(12);//顶部标题文字大小
        picker.setCancelTextColor(0xFF33B5E5);//顶部取消按钮文字颜色
        picker.setCancelTextSize(14);
        picker.setSubmitTextColor(0xFF33B5E5);//顶部确定按钮文字颜色
        picker.setSubmitTextSize(14);
        picker.setTextColor(0xFFEE0000, 0xFF999999);//中间滚动项文字颜色
        WheelView.LineConfig config = new WheelView.LineConfig();
        config.setColor(0xFFEE0000);//线颜色
        config.setAlpha(140);//线透明度
        picker.setLineConfig(config);
        picker.setBackgroundColor(0xFFE1E1E1);
        //picker.setSelectedItem(isChinese ? "射手" : "Sagittarius");
        picker.setSelectedIndex(10);//默认选中项
        picker.setOnOptionPickListener(new OptionPicker.OnOptionPickListener() {
            @Override
            public void onOptionPicked(int index, String item) {
                showToast("index=" + index + ", item=" + item);
            }
        });
        picker.show();
