lxinyue/BGAAdapter-Android

在AdapterView和RecyclerView中通用的Adapter和ViewHolder

🏃BGAAdapter-Android🏃

在AdapterView和RecyclerView中通用的Adapter和ViewHolder，使AdapterView和RecyclerView适配器的使用方式基本一致。 其中拖拽排序是参考的Android-ItemTouchHelper-Demo

效果图

Gradle

dependencies {
    compile 'com.android.support:recyclerview-v7:latestVersion'
    compile 'cn.bingoogolapple:bga-adapter:latestVersion@aar'
}

使用非常简单，这里展示一下ListView和RecyclerView实现qq聊天界面的适配器

ListView实现qq聊天界面的适配器

public class ListChatAdapter extends BGAAdapterViewAdapter<ChatModel> {

    public ListChatAdapter(Context context) {
        super(context, R.layout.item_chat);
    }

    /**
     * 为item的孩子节点设置监听器，并不是每一个数据列表都要为item的子控件添加事件监听器，所以在父类中采用了空实现，需要设置事件监听器时重写该方法即可
     *
     * @param viewHolderHelper
     */
    @Override
    protected void setItemChildListener(BGAViewHolderHelper viewHolderHelper) {
    }

    @Override
    public void fillData(BGAViewHolderHelper viewHolderHelper, int position, ChatModel model) {
        if (model.mUserType == ChatModel.UserType.From) {
            viewHolderHelper.setVisibility(R.id.rl_item_chat_to, View.GONE);
            viewHolderHelper.setVisibility(R.id.rl_item_chat_from, View.VISIBLE);
            String htmlMsg = String.format(mContext.getString(R.string.color_msg_from), model.mMsg);
            viewHolderHelper.setHtml(R.id.tv_item_chat_from_msg, htmlMsg);
        } else {
            viewHolderHelper.setVisibility(R.id.rl_item_chat_from, View.GONE);
            viewHolderHelper.setVisibility(R.id.rl_item_chat_to, View.VISIBLE);
            String htmlMsg = String.format(mContext.getString(R.string.color_msg_to), model.mMsg);
            viewHolderHelper.setHtml(R.id.tv_item_chat_to_msg, htmlMsg);
        }
    }

}

RecyclerView实现qq聊天界面的适配器

public class RecyclerChatAdapter extends BGARecyclerViewAdapter<ChatModel> {
    public RecyclerChatAdapter(RecyclerView recyclerView) {
        super(recyclerView, R.layout.item_chat);
    }

    /**
     * 为item的孩子节点设置监听器，并不是每一个数据列表都要为item的子控件添加事件监听器，所以在父类中采用了空实现，需要设置事件监听器时重写该方法即可
     *
     * @param viewHolderHelper
     */
    @Override
    public void setItemChildListener(BGAViewHolderHelper viewHolderHelper) {
    }

    @Override
    public void fillData(BGAViewHolderHelper viewHolderHelper, int position, ChatModel model) {
        if (model.mUserType == ChatModel.UserType.From) {
            viewHolderHelper.setVisibility(R.id.rl_item_chat_to, View.GONE);
            viewHolderHelper.setVisibility(R.id.rl_item_chat_from, View.VISIBLE);
            String htmlMsg = String.format(mContext.getString(R.string.color_msg_from), model.mMsg);
            viewHolderHelper.setHtml(R.id.tv_item_chat_from_msg, htmlMsg);
        } else {
            viewHolderHelper.setVisibility(R.id.rl_item_chat_from, View.GONE);
            viewHolderHelper.setVisibility(R.id.rl_item_chat_to, View.VISIBLE);
            String htmlMsg = String.format(mContext.getString(R.string.color_msg_to), model.mMsg);
            viewHolderHelper.setHtml(R.id.tv_item_chat_to_msg, htmlMsg);
        }
    }

}
