### Initializing and Using ChannelView in Android Activity

Source: https://github.com/chengzhicao/channelview/blob/master/README.md

Provides a comprehensive example of how to initialize the ChannelView in an Android Activity. It demonstrates populating the view with various channel lists, setting fixed channel counts, adding multiple channel plates, and implementing listeners for channel item clicks and edit finish events.

```Java
public class ChannelViewActivity extends AppCompatActivity implements ChannelView.OnChannelListener {
    private String TAG = getClass().getSimpleName();
    private ChannelView channelView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_channel_view);

        channelView = findViewById(R.id.channelView);
        init();
    }

    private void init() {
        String[] myChannel = {"要闻", "视频", "新时代", "娱乐", "体育", "军事", "NBA", "国际", "科技", "财经", "汽车", "电影", "游戏", "独家", "房产",
                "图片", "时尚", "呼和浩特", "三打白骨精"};
        String[] recommendChannel1 = {"综艺", "美食", "育儿", "冰雪", "必读", "政法网事", "都市",
                "NFL", "韩流"};
        String[] recommendChannel2 = {"问答", "文化", "佛学", "股票", "动漫", "理财", "情感", "职场", "旅游"};
        String[] recommendChannel3 = {"家居", "电竞", "数码", "星座", "教育", "美容", "电视剧",
                "搏击", "健康"};

        List<Channel> myChannelList = new ArrayList<>();
        List<Channel> recommendChannelList1 = new ArrayList<>();
        List<Channel> recommendChannelList2 = new ArrayList<>();
        List<Channel> recommendChannelList3 = new ArrayList<>();

        for (int i = 0; i < myChannel.length; i++) {
            String aMyChannel = myChannel[i];
            Channel channel;
            if (i > 2 && i < 6) {
                //可设置频道归属板块（channelBelong），当前设置此频道归属于第二板块，当删除该频道时该频道将回到第二板块
                channel = new Channel(aMyChannel, 2, i);
            } else if (i > 7 && i < 10) {
                //可设置频道归属板块（channelBelong），当前设置此频道归属于第三板块，当删除该频道时该频道将回到第三板块中
                channel = new Channel(aMyChannel, 3, i);
            } else {
                channel = new Channel(aMyChannel, (Object) i);
            }
            myChannelList.add(channel);
        }

        for (String aMyChannel : recommendChannel1) {
            Channel channel = new Channel(aMyChannel);
            recommendChannelList1.add(channel);
        }

        for (String aMyChannel : recommendChannel2) {
            Channel channel = new Channel(aMyChannel);
            recommendChannelList2.add(channel);
        }

        for (String aMyChannel : recommendChannel3) {
            Channel channel = new Channel(aMyChannel);
            recommendChannelList3.add(channel);
        }

        channelView.setChannelFixedCount(3);
        channelView.addPlate("我的频道", myChannelList);
        channelView.addPlate("推荐频道", recommendChannelList1);
        channelView.addPlate("国内", recommendChannelList2);
        channelView.addPlate("国外", recommendChannelList3);
        channelView.inflateData();
        channelView.setOnChannelItemClickListener(this);
    }


    @Override
    public void channelItemClick(int position, Channel channel) {
        Log.i(TAG, position + ".." + channel);
    }

    @Override
    public void channelEditFinish(List<Channel> channelList) {
        Log.i(TAG, channelList.toString());
        Log.i(TAG, channelView.getMyChannel().toString());
    }
    
    @Override
    public void channelEditStart() {

    }
}
```

### ChannelView API: Core Methods

Source: https://github.com/chengzhicao/channelview/blob/master/README.md

Essential methods for configuring and interacting with the ChannelView, including setting adapters, managing channel counts, and retrieving channel data.

```APIDOC
void setStyleAdapter(StyleAdapter styleAdapter): Sets the adapter, the most important method, can implement data population and custom styles.
void setInsertRecommendPosition(int recommendPosition): Sets the insertion position into 'My Channels', if not set, defaults to insertion at the end.
void setChannelFixedCount(int channelFixedCount): Sets the number of fixed channels.
boolean isChange(): Checks if the channel sequence has changed.
List<Channel> getMyChannel(): Gets the content of 'My Channels'.
List<List<Channel>> getOtherChannel(): Gets the content of 'Other Channels'.
void setOnChannelListener(OnChannelListener onChannelListener): Sets the listener.
```

An overview of the main classes and interfaces provided by ChannelView for customizing its behavior, styling, and data handling.

```APIDOC
StyleAdapter: Interface, defines channel style implementation and data population, used for custom styles.
BaseStyleAdapter: Abstract class, implements part of StyleAdapter methods, use it for custom styles without fully implementing StyleAdapter methods.
DefaultStyleAdapter: Inherits BaseStyleAdapter, is the default implementation class for channel styles, can also be used for simple style customization.
ViewHolder: Class used with StyleAdapter, saves controls in custom style layouts.
ChannelListenerAdapter: Abstract class, implements ChannelView.OnChannelListener2 method, a new listener that can listen to specific events.
```

Add the JitPack Maven repository to your project's root `build.gradle` file to enable dependency resolution for ChannelView.

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

### Customizing ChannelView Item Styles and ViewHolder

Source: https://github.com/chengzhicao/channelview/blob/master/README.md

Demonstrates how to customize the appearance of ChannelView items by overriding `setFocusedStyle` and defining a custom `MyViewHolder` to access specific views within the item layout. This allows for dynamic styling based on focus state and efficient view lookup.

```Java
viewHolder.iv.setVisibility(View.VISIBLE);
        }

        @Override
        public void setFocusedStyle(MyViewHolder viewHolder) {
            viewHolder.tv.setBackgroundResource(R.drawable.bg_channel_custom_focused);
        }

        class MyViewHolder extends ViewHolder {
            TextView tv;
            ImageView iv;

            public MyViewHolder(View itemView) {
                super(itemView);
                tv = itemView.findViewById(R.id.tv_channel);
                iv = itemView.findViewById(R.id.iv_delete);
            }
        }
```

--------------------------------

### ChannelView API: Listener Interface Methods

Source: https://github.com/chengzhicao/channelview/blob/master/README.md

Methods defined within the ChannelView listener interface for handling various user interactions and state changes, such as item clicks and editing events.

```APIDOC
void channelItemClick(int position, Channel channel): Callback for channel item click.
void channelEditFinish(List<Channel> channelList): Callback for channel editing completion.
void channelEditStart(): Callback for starting channel editing.
void channelEditStateItemClick(int position, Channel channel): Callback for channel item click in edit state.
```

--------------------------------

### Add ChannelView Dependency in Gradle

Source: https://github.com/chengzhicao/channelview/blob/master/README.md

Include the ChannelView library as an implementation dependency in your app's `build.gradle` file. It is recommended to set `compileSdkVersion` to 28 or higher to avoid compilation issues.

```Groovy
dependencies {
        implementation 'com.github.chengzhicao:ChannelView:v1.1.2'
}
```
