来了！真Material Design版的玩Android

玩Android大家都很熟悉了，是鸿洋大佬的一个开源知识网站，目前基于玩Android开源API的各种版本APP也多是如牛毛。

那么经过一段时间的潜心修炼，今天给大家带来了一个从未有过的船新版本。

设计

这次的UI整体是根据Google官方的设计，参照Material Design的风格整粗来的，应该能给大家带来耳目一新的感觉。

下面我们先来看看效果图

底部导航栏使用了BottomAppbar和FloatingActionButton组件

MaterialShapeDrawable实现了展开菜单的Material丝滑动画

private val foregroundShapeDrawable: MaterialShapeDrawable by lazy(NONE) {        val foregroundContext = binding.foregroundContainer.context        MaterialShapeDrawable(            foregroundContext,            null,            R.attr.bottomSheetStyle,            0        ).apply {            fillColor = ColorStateList.valueOf(                foregroundContext.themeColor(R.attr.colorPrimarySurface)            )            elevation = resources.getDimension(R.dimen.plane_16)            shadowCompatibilityMode = MaterialShapeDrawable.SHADOW_COMPAT_MODE_NEVER            initializeElevationOverlay(requireContext())            shapeAppearanceModel = shapeAppearanceModel.toBuilder()                .setTopEdge(                        SemiCircleEdgeCutoutTreatment(                        resources.getDimension(R.dimen.grid_2),                        resources.getDimension(R.dimen.grid_3),                        0F,                        resources.getDimension(R.dimen.navigation_drawer_profile_image_size_padded)                    )                )                .build()        }    }

技术

技术方面采用的是Kotlin语言实现，整体架构为MVVM，使用协程配合Retrofit来创建和处理网络请求的异步任务。

封装了dataBinding和viewBinding的懒加载

/** * Fragment ViewBinding Delegate */fun  Fragment.viewBinding(viewBindingFactory: (View) -> T) =    FragmentViewBindingDelegate(this, viewBindingFactory)class FragmentViewBindingDelegate(    val fragment: Fragment,    val viewBindingFactory: (View) -> T) : ReadOnlyProperty {    private var _binding: T? = null    init {        fragment.lifecycle.addObserver(object : DefaultLifecycleObserver {            override fun onCreate(owner: LifecycleOwner) {                fragment.viewLifecycleOwnerLiveData.observe(fragment) { viewLifecycleOwner ->                    viewLifecycleOwner.lifecycle.addObserver(object : DefaultLifecycleObserver {                        override fun onDestroy(owner: LifecycleOwner) {                            _binding = null                        }                    })                }            }        })    }    override fun getValue(thisRef: Fragment, property: KProperty<*>): T {        val binding = _binding        if (binding != null) {            return binding        }        val lifecycle = fragment.viewLifecycleOwner.lifecycle        if (!lifecycle.currentState.isAtLeast(Lifecycle.State.INITIALIZED)) {            throw IllegalStateException("Should not attempt to get bindings when Fragment views are destroyed.")        }        return viewBindingFactory(thisRef.requireView()).also { _binding = it }    }}
