# ChildComponentTest

创建一个id为child_layout的DirectionalLayout用来装载子布局

```
<DirectionalLayout
        ohos:id="$+id:child_layout"
        ohos:height="match_parent"
        ohos:width="match_parent"
        />
```

子布局
```
<?xml version="1.0" encoding="utf-8"?>
<DirectionalLayout
    xmlns:ohos="http://schemas.huawei.com/res/ohos"
    ohos:height="match_parent"
    ohos:width="match_parent"
    ohos:orientation="vertical">
    ...
</DirectionalLayout>
```
新建一个Test类，继承ComponentContainer类

使用LayoutScatter的parse方法生成子布局的对象
```
Component cptLayout = LayoutScatter.getInstance(context)
                .parse(ResourceTable.Layout_ability_test, null, false);
```

把该对象添加到Test组件中
```
addComponent(cptLayout);
```

在AbilitySlice中创建Test实例，添加到装载子布局的容器中

```
    Test test = new Test(this);
    layout.addComponent(test);
```
