}Presenter层处理业务逻辑在Presenter中初始化选择器并处理结果回调public class AddressPresenter implements OnAddressPickedListener { private AddressView view; public void showAddressPicker(Context context) { AddressPicker picker new AddressPicker(context); picker.setOnAddressPickedListener(this); picker.show(); } Override public void onAddressPicked(ProvinceEntity province, CityEntity city, CountyEntity county) { view.updateAddress(province.getName() city.getName() county.getName()); } }View层专注UI更新Activity/Fragment实现View接口接收Presenter的数据更新public class AddressActivity extends AppCompatActivity implements AddressView { private AddressPresenter presenter; Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); presenter new AddressPresenter(this); findViewById(R.id.btn_pick).setOnClickListener(v - presenter.showAddressPicker(this)); } Override public void updateAddress(String address) { ((TextView) findViewById(R.id.tv_address)).setText(address); } }日期选择器MVP实现示例上图展示了日期时间选择器的典型界面在MVP架构中可通过Dialog封装实现public class DateTimePresenter { private DateTimeView view; public void showDateTimePicker(Activity activity) { DatimePicker picker new DatimePicker(activity); picker.setOnDatimePickedListener((date, time) - { view.onDateTimeSelected(date time); }); picker.show(); } } MVVM架构整合方案使用ViewModel管理选择器状态创建ViewModelpublic class PickerViewModel extends ViewModel { private MutableLiveDataString selectedColor new MutableLiveData(); public LiveDataString getSelectedColor() { return selectedColor; } public void showColorPicker(Context context) { ColorPicker picker new ColorPicker(context); picker.setOnColorPickedListener(color - { selectedColor.postValue(ColorUtils.colorToString(color)); }); picker.show(); } }Activity中观察数据变化public class ColorPickerActivity extends AppCompatActivity { private PickerViewModel viewModel; Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); viewModel new ViewModelProvider(this).get(PickerViewModel.class); viewModel.getSelectedColor().observe(this, color - { findViewById(R.id.layout_bg).setBackgroundColor(Color.parseColor(color)); }); findViewById(R.id.btn_pick_color).setOnClickListener(v - viewModel.showColorPicker(this) ); } }日历选择器MVVM实现示例日历选择器适合酒店预订等场景在MVVM架构中可这样实现public class CalendarViewModel extends ViewModel { private MutableLiveDataDateRange selectedDateRange new MutableLiveData(); public void showCalendarPicker(Activity activity) { CalendarPicker picker new CalendarPicker(activity); picker.setOnRangeDatePickListener((start, end) - { selectedDateRange.postValue(new DateRange(start, end)); }); picker.show(); } } 高级整合技巧1. 选择器生命周期管理在Common/src/main/java/com/github/gzuliyujiang/dialog/BaseDialog.java中框架已实现生命周期感知public abstract class BaseDialog extends Dialog implements LifecycleEventObserver { Override public void onStateChanged(NonNull LifecycleOwner source, NonNull Lifecycle.Event event) { if (event Lifecycle.Event.ON_DESTROY) { DialogLog.print(dismiss dialog when source.getClass().getName() on destroy); dismiss(); } } }2. 自定义选择器样式通过DialogConfig类可全局配置选择器样式DialogConfig.getInstance() .setDialogStyle(DialogStyle.THREE) .setDialogColor(new DialogColor() .contentBackgroundColor(0xFFFFFFFF) .titleTextColor(0xFF333333));3. 多类型选择器统一管理通过工厂模式统一管理不同类型选择器public class PickerFactory { public static BaseDialog createPicker(Context context, PickerType type) { switch (type) { case ADDRESS: return new AddressPicker(context); case DATE: return new DatePicker(context); case COLOR: return new ColorPicker(context); default: throw new IllegalArgumentException(Unsupported picker type); } } } 整合步骤总结添加依赖将AndroidPicker模块导入项目确保settings.gradle中包含所有模块include :AddressPicker, :CalendarPicker, :ColorPicker, :Common, :FilePicker, :ImagePicker, :WheelPicker, :WheelView, :app根据架构选择整合方式MVP创建Contract接口在Presenter中处理选择逻辑MVVM使用ViewModel LiveData管理选择状态处理配置变更利用ViewModel或Presenter的生命周期感知能力确保配置变更后选择状态不丢失自定义样式通过DialogConfig和DialogColor类统一设置选择器样式AndroidPicker提供了丰富的选择器组件和灵活的API通过本文介绍的架构整合方案开发者可以轻松将其集成到MVVM或MVP项目中构建出既美观又易于维护的安卓应用。无论是简单的日期选择还是复杂的地址联动选择AndroidPicker都能满足你的需求。【免费下载链接】AndroidPicker安卓选择器类库包括日期及时间选择器可用于出生日期、营业时间等、单项选择器可用于性别、民族、职业、学历、星座等、二三级联动选择器可用于车牌号、基金定投日期等、城市地址选择器分省级、地市级及区县级、数字选择器可用于年龄、身高、体重、温度等、日历选日期择器可用于酒店及机票预定日期、颜色选择器、文件及目录选择器、图片选择器等……WheelPicker/DatePicker/TimePicker/OptionPicker/NumberPicker/LinkagePicker/AddressPicker/CarPlatePicker/CalendarPicker/ColorPicker/FilePicker/ImagePicker etc.项目地址: https://gitcode.com/gh_mirrors/an/AndroidPicker创作声明：本文部分内容由AI辅助生成（AIGC），仅供参考
