混淆规则

项目库混淆无需额外配置。

用法示例

常见用法请参阅 demo，高级用法请细读源码，诸如可以重写同名的assets/china_address.json来自定义省市区数据，重写同名的DialogSheetAnimation来自定义弹窗动画……。代码是最好的老师，强烈建议拉取代码运行，尝试修改 demo 对比查看实际效果以便加深理解。

        app:wheel_dayLabel="日"
        app:wheel_monthLabel="月" />

    ...

</LinearLayout>

自定义样式（可选）

全局配置所有选择器样式及配色

//4.0.0版本开始内置支持四种弹窗样式（Default、One、Two、Three），效果可运行Demo查看
public class DemoApp extends Application {

    @Override
    public void onCreate() {
        super.onCreate();
        DialogConfig.setDialogStyle(DialogStyle.Default);
        DialogConfig.setDialogColor(new DialogColor()
                .cancelTextColor(0xFF999999)
                .okTextColor(0xFF0099CC));
    }

}

自定义 style

调用setStyle（只作用于当前选择器，推荐）

在app/.../res/values/styles.xml中参考WheelDefault写个style，然后设置。

picker.getWheelView().setStyle(R.style.WheelStyleDemo);

重写WheelDefault覆盖 （所有选择器都会生效，不推荐）

在app/.../res/values/styles.xml中重写WheelDefault覆盖 。

<style name="WheelDefault">
    <item name="wheel_itemSpace">15dp</item>
    <item name="wheel_itemTextColor">@android:color/darker_gray</item>
    <item name="wheel_itemTextColorSelected">@android:color/holo_blue_dark</item>
    <item name="wheel_itemTextSize">16sp</item>
    <item name="wheel_itemTextSizeSelected">18sp</item>
    <item name="wheel_itemTextBoldSelected">false</item>
    <item name="wheel_sameWidthEnabled">false</item>
    <item name="wheel_atmosphericEnabled">true</item>
    <item name="wheel_curtainEnabled">false</item>
    <item name="wheel_curtainColor">#FFDEDEDE</item>
    <item name="wheel_curvedEnabled">false</item>
    <item name="wheel_curvedMaxAngle">90</item>
    <item name="wheel_cyclicEnabled">false</item>
    <item name="wheel_indicatorEnabled">true</item>
    <item name="wheel_indicatorColor">@android:color/holo_blue_light</item>
    <item name="wheel_indicatorSize">1dp</item>
</style>

在Java中集成重写某一选择器样式及配色

//仿蚂蚁财富APP定投周期选择弹窗样式
public class AntFortuneLikePicker extends LinkagePicker {
    private int lastDialogStyle;

    public AntFortuneLikePicker(@NonNull Activity activity) {
        super(activity);
    }

    @Override
    protected void onInit(@NonNull Context context) {
        super.onInit(context);
        lastDialogStyle = DialogConfig.getDialogStyle();
        DialogConfig.setDialogStyle(DialogStyle.Default);
    }

    @Override
    public void onDismiss(DialogInterface dialog) {
        super.onDismiss(dialog);
        DialogConfig.setDialogStyle(lastDialogStyle);
    }

    @Override
    protected void initData() {
        super.initData();
        setBackgroundColor(0xFFFFFFFF);
        cancelView.setText("取消");
        cancelView.setTextSize(16);
        cancelView.setTextColor(0xFF0081FF);
        okView.setTextColor(0xFF0081FF);
        okView.setText("确定");
        okView.setTextSize(16);
        titleView.setTextColor(0xFF333333);
        titleView.setText("定投周期");
        titleView.setTextSize(16);
        wheelLayout.setData(new AntFortuneLikeProvider());
        wheelLayout.setAtmosphericEnabled(true);
        wheelLayout.setVisibleItemCount(7);
        wheelLayout.setCyclicEnabled(false);
        wheelLayout.setIndicatorEnabled(true);
        wheelLayout.setIndicatorColor(0xFFDDDDDD);
        wheelLayout.setIndicatorSize((int) (contentView.getResources().getDisplayMetrics().density * 1));
        wheelLayout.setTextColor(0xFF999999);
        wheelLayout.setSelectedTextColor(0xFF333333);
        wheelLayout.setCurtainEnabled(false);
        wheelLayout.setCurvedEnabled(false);
    }

}

和`DialogFragment`结合

XXXPicker 都继承自 android.app.Dialog ，因此可以直接和androidx.fragment.app.DialogFragment结合使用。

public class OptionPickerFragment extends DialogFragment {

    @NonNull
    @Override
    public Dialog onCreateDialog(@Nullable Bundle savedInstanceState) {
        OptionPicker picker = new OptionPicker(requireActivity());
        picker.setData("土人", "里民子", "羡民", "穿青人", "不在56个民族之内", "未定民族");
        picker.setOnOptionPickedListener(new OnOptionPickedListener() {
            @Override
            public void onOptionPicked(int position, Object item) {
                Toast.makeText(requireContext(), item.toString(), Toast.LENGTH_SHORT).show();
            }
        });
        picker.getWheelView().setStyle(R.style.WheelStyleDemo);
        return picker;
    }

}
