MultiStatePage的功能及特点

• 无需在布局添加视图代码
• 可显示自定义状态视图,任意拓展
• 可用于 Activity、Fragment、或指定的 View
• 自定义重新请求监听
• 可动态更新视图样式
• 可结合第三方控件使用
• 支持状态回调监听
• kotlin开发更易用的API

开始

添加依赖

Step1. Add the JitPack repository to your build file

allprojects {
    repositories {
        maven { url 'https://jitpack.io' }
    }
}

Step2. Add the dependency

dependencies {
    implementation 'com.github.Zhao-Yan-Yan:MultiStatePage:1.0.9'
}

1.生成MultiStateContainer

在View上使用

kotlin

基础用法

val multiStateContainer = MultiStatePage.bindMultiState(view)

val multiStateContainer = MultiStatePage.bindMultiState(view) { multiStateContainer: MultiStateContainer ->
    // 重试事件处理
}

拓展方法

val multiStateContainer = view.bindMultiState()

val multiStateContainer = view.bindMultiState() { multiStateContainer: MultiStateContainer ->
    // 重试事件处理
}

java

MultiStateContainer multiStateContainer = MultiStatePage.bindMultiState(view)

MultiStateContainer multiStateContainer = MultiStatePage.bindMultiState(view, new OnRetryEventListener() {
    @Override
    public void onRetryEvent(MultiStateContainer multiStateContainer) {
        // 重试事件处理
    }
});

在Activity 根View中使用

kotlin

基础用法

val multiStateContainer = MultiStatePage.bindMultiState(this)

val multiStateContainer = MultiStatePage.bindMultiState(this) { multiStateContainer: MultiStateContainer ->
    // 重试事件处理
}

拓展方法

val multiStateContainer = bindMultiState()

val multiStateContainer = bindMultiState() { multiStateContainer: MultiStateContainer ->
    // 重试事件处理
}

java

MultiStateContainer multiStateContainer = MultiStatePage.bindMultiState(this);

MultiStateContainer multiStateContainer = MultiStatePage.bindMultiState(this, new OnRetryEventListener() {
    @Override
    public void onRetryEvent(MultiStateContainer multiStateContainer) {
        // 重试事件处理   
    }
});

在Fragment根View中使用

kotlin

class MultiStateFragment : Fragment {
    
    private lateinit var multiStateContainer: MultiStateContainer
    
    override fun onCreateView(
        inflater: LayoutInflater,
        container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View? {
        val root = inflater.inflate(R.layout.fragment, container, false)
        multiStateContainer = MultiStatePage.bindMultiState(root) { multiStateContainer: MultiStateContainer ->
            // 重试事件处理
        }
        //或者
        multiStateContainer = root.bindMultiState() { multiStateContainer: MultiStateContainer ->
            // 重试事件处理
        }
        return multiStateContainer
    }
}

java

class JavaFragment extends Fragment {
    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View root = inflater.inflate(R.layout.activity_main, container, false);
        MultiStateContainer multiStateContainer = MultiStatePage.bindMultiState(root);
        return multiStateContainer;
    }
}

2.切换状态

调用 MultiStateContainer.show<T>() 方法

默认内置3种状态

val multiStateContainer = MultiStatePage.bindMultiState(view)
//成功页 
multiStateContainer.show<SuccessState>()
//错误页
multiStateContainer.show<ErrorState>()
//空页面
multiStateContainer.show<EmptyState>()
//加载状态页
multiStateContainer.show<LoadingState>()

1.1.0新增 show(multiState: MultiState)

val lottieOtherState = LottieOtherState()
lottieOtherState.retry = {
	Toast.makeText(this, "retry...", Toast.LENGTH_SHORT).show()
}
multiStateContainer.show(lottieOtherState)

动态设置state

multiStateContainer.show<ErrorState>{errorState ->
    errorState.setErrorMsg("xxx出错了")
}

设置重试回调

val multiStateContainer = MultiStatePage.bindMultiState(view){
    Toast.makeText(context, "retry", Toast.LENGTH_SHORT).show()
}

自定义State

1.继承MultiState

class LottieWaitingState : MultiState() {
    override fun onCreateMultiStateView(
        context: Context,
        inflater: LayoutInflater,
        container: MultiStateContainer
    ): View {
        return inflater.inflate(R.layout.multi_lottie_waiting, container, false)
    }

    override fun onMultiStateViewCreate(view: View) {
        //逻辑处理
    }
    
    //是否允许重试
    override fun enableReload(): Boolean = false
    
    //指定重试 view
    override fun bindRetryView(): View? {
        return retryView
    }
}

enableReload() 是否允许retry回调 false不允许

bindRetryView 绑定重试点击事件的view 默认为根view

结合ViewBidng 参考 demo MultiStateBinding 和 WithBindingState

2.show (1.0.3后无需register)

class LottieExtActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        val multiStateContainer = bindMultiState()
        multiStateContainer.show<LottieWaitingState>()
    }
}

使用内置状态配置

class App : Application() {
    override fun onCreate() {
        super.onCreate()
        val config = MultiStateConfig.Builder()
            .alphaDuration(300)
            .errorIcon(R.mipmap.state_error)
            .emptyIcon(R.mipmap.state_empty)
            .emptyMsg("emptyMsg")
            .loadingMsg("loadingMsg")
            .errorMsg("errorMsg")
            .build()
        MultiStatePage.config(config)
    }
}

method	作用
alphaDuration	alpha动画时长
errorIcon	错误状态默认图标
emptyIcon	空数据状态默认图标
emptyMsg	空数据状态默认提示信息
errorMsg	错误状态默认提示信息
loadingMsg	loading状态默认提示信息

小技巧

可以借助kotlin的拓展函数封装常用的状态

fun MultiStateContainer.showSuccess(callBack: (SuccessState) -> Unit = {}) {
    show<SuccessState> {
        callBack.invoke(it)
    }
}

fun MultiStateContainer.showError(callBack: (ErrorState) -> Unit = {}) {
    show<ErrorState> {
        callBack.invoke(it)
    }
}

fun MultiStateContainer.showEmpty(callBack: (EmptyState) -> Unit = {}) {
    show<EmptyState> {
        callBack.invoke(it)
    }
}

fun MultiStateContainer.showLoading(callBack: (LoadingState) -> Unit = {}) {
    show<LoadingState> {
        callBack.invoke(it)
    }
}

调用

val multiStateContainer = bindMultiState()
multiStateContainer.showLoading()
multiStateContainer.showSuccess()
