# DoubleStickyHeadersList

一个OpenHarmony库，用于粘贴到列表顶部的双层节头。OpenHarmony小部件，特别用于显示具有多级分类的项目。

# 使用
#### 1. 在项目中使用库。

 添加Gradle:

添加下面的代码到`build.gradle`:

```xml
dependencies {
    implementation 'com.gitee.baijuncheng-open-source:DoubleStickyHeaderList:1.0.1'
}
```

#### 2.将`layout.xml`文件中的`ListContainer`替换为`com.kenber.view.DoubleStickyHeaderListView`。

```xml
<com.kenber.view.DoubleStickyHeaderListView
    xmlns:ohos="http://schemas.huawei.com/res/ohos"
    ohos:height="match_content"
    ohos:width="match_parent"/>
```

#### 3. 使`DoubleStickyHeaderListView`的`adapter`实现`doubleStickHeaderListAdapter`接口。您需要重写`getHeaderLevel(int position)`方法来告诉`DoubleStickyHeaderListView`哪个标头应该作为级别0或级别1粘滞，或者作为级别2不粘滞,重写`getHeader0Color()`表示级别0的头部绘制的颜色，`getHeader1Color()`表示级别1的头部绘制的颜色。

```java
public class ListAdapter extends ArrayAdapter<ListItem> implements DoubleStickHeadersListAdapter {

    ...
        
    @Override
    public int getHeaderLevel(int position) {
        return getItem(position).level;
    }
    @Override
    public int getHeader0Color() {
        return BG_COLOR_LEVEL_0;
    }

    @Override
    public int getHeader1Color() {
        return BG_COLOR_LEVEL_1;
    }
}

```
#### 4.如果拥有头部列表，可以使用下面的接口设置头部的点击事件

```
listView.setHeadClick(this);
```

#### 5.需要设置绘制区域的文字大小，可以使用下面的方法

```
listView.setTextsize(16);
```

#### 6.注意事项
**该库最多实现两级吸顶，并且不能跳级（不能不设置一级直接设置二级）**


现在，一切都结束了。此库的示例可在`example`文件夹中找到。
