#### 安装教程

1.在项目根目录下的build.gradle文件中，
 ```
 allprojects {
    repositories {
        maven {
            url 'https://s01.oss.sonatype.org/content/repositories/releases/'
        }
    }
 }
 ```
2.在entry模块的build.gradle文件中，
 ```
 dependencies {
    implementation('com.gitee.chinasoft_ohos:RxDiffUtil:1.0.1')
    ......  
 }
 ```

在sdk5，DevEco Studio 2.2 Beta1下项目可直接运行
如无法运行，删除项目.gradle,.idea,build,gradle,build.gradle文件，
并依据自己的版本创建新项目，将新项目的对应文件复制到根目录下


## 使用说明
1.创建CustomTableLayout对象，并绑定Provider
```
    CustomTableLayout customTableLayout = new CustomTableLayout(this);
            customTableLayout.setLayoutConfig(new DirectionalLayout.LayoutConfig(
                    ComponentContainer.LayoutConfig.MATCH_PARENT, ComponentContainer.LayoutConfig.MATCH_CONTENT));
            DirectionalLayout directionalLayout = (DirectionalLayout) findComponentById(ResourceTable.Id_dl);
            directionalLayout.removeAllComponents();
            directionalLayout.addComponent(customTableLayout);
    
            customTableLayout.setChangeDataListener(this);
            provider = new MyProvider(LayoutScatter.getInstance(this));
            List<Thing> emptyList = new ArrayList<>();
            Pair<List<Thing>, DiffResult> initialPair = Pair.create(emptyList, null);
            disposable = ThingRepository
                    .latestThings(FIVE_CHANGE_DATA_TIME, TimeUnit.SECONDS)
                    .scan(initialPair, (pair, next) -> {
                        DiffResult result = calculateDiff();
                        return Pair.create(next, result);
                    })
                    .skip(1)
                    .subscribeOn(computation())
                    .observeOn(mainThread())
                    .subscribe(listDiffResultPair -> {
                        provider.setThings(listDiffResultPair.f);
                        listDiffResultPair.s.dispatchUpdatesTo(customTableLayout, provider);
                    });
```
