StickyListHeaders

StickyListHeaders makes it easy to integrate section headers in your ListContainer.These section headers stick to the top. The goal of this project is to deliver a high performance replacement to ListContainer.You should with minimal effort and time be able to add section headers to a list. This should be done via a simple to use API without any special features.

StickyListHeaders includes :

• Displays the section headers in your ListContainer.
• Displays section headers stick to the top.
• Supports customized background color to sticky header background, header text and list container background.

Usage Instructions

The following core classes are the essential interface to StickyListHeaders:

StickyListHeadersAdapter: Transaction item provider for list container.

	public class StickyListHeadersAdapter extends BaseItemProvider

StickyListHeadersAdapter.java

---

public Component getComponent(int position, Component convertView, ComponentContainer componentContainer) { Component component = convertView; if (component == null) { component = LayoutScatter.getInstance(context).parse(ResourceTable.Layout_list_item, null, false); }

String itemName = mData.get(position).getName();
boolean isHeader = mData.get(position).isHeader();

Text code = (Text) component.findComponentById(ResourceTable.Id_item_name);
code.setBackground(customElement(isHeader));     
code.setText(itemName);

return component;

}

StickyModel: Model class for sticky list header name.

	public class StickyModel

ViewUtil: Util class to set custom element for header text.

	public class ViewUtil

LogUtil: LogUtil is intended to be use for add log messages.

	public class LogUtil

The steps to initialize the StickyListHeaders and example:

StickyListHeadersAdapter listItemProvider = new StickyListHeadersAdapter(this, mStickyList);
listItemProvider.setResource(ResourceTable.Layout_list_item, ResourceTable.Id_item_name);
listItemProvider.setColor(listItemProvider.DEFAULT_HEADER_BG_COLOR, listItemProvider.DEFAULT_LIST_BG_COLOR);
mListContainer.setItemProvider(listItemProvider);

Text headerName = (Text) mView.findComponentById(ResourceTable.Id_header_name);
headerName.setBackground(ViewUtil.customElement(ViewUtil.DEFAULT_HEADER_TEXT_COLOR));
headerName.setClickedListener(this);

mListContainer.setScrolledListener(this);

super.setUIContent(mView);

Please refer the sample app which has StickyListHeaders component on top of list component. To use StickyListHeaders in your own ohos project, simply copy stickylistheaders.har (available from this repository's package) into your project's /libs directory and add it to the build path.

Installation Instructions

1.For using StickyListHeaders module in sample app, Add the dependencies in entry/build.gradle as below :

	dependencies {
		implementation project(path: ':library')
	}

2.Using the library.har, make sure to add library.har file in the entry/libs folder.

Modify the dependencies in the entry/build.gradle file.
	dependencies {
		implementation fileTree(dir: 'libs', include: [' *.jar', ' *.har'])
	}

3. For using StickyListHeaders from a remote repository in separate application, add the below dependencies :

    Modify entry build.gradle as below :
    ```
    dependencies {
        implementation 'io.openharmony.tpc.thirdlib:StickyListHeaders:1.0.1'
    }
    ```
