RecycleView添加頭部、點擊事件的監聽

RecycleView添加頭部佈局其實就是通過Adapter中的Position來分辨的，當position爲0時膨脹頭佈局，其他position返回常規佈局:

public static final int TYPE_FIRSTHEADVIEW = 0;//第一個頭佈局
public static final int TYPE_SECHEADVIEW = 1; //第二個頭佈局
public static final int TYPE_NORMALVIEW = 2; //RecycleView佈局

@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    if (viewType == TYPE_FIRSTHEADVIEW) {
        //第一個頭佈局View
        View view = mLayoutInflater.inflate(R.layout.recycle_firstheadview, parent, false);

        return new HeaderViewHolder(view);
    } else if (viewType == TYPE_SECHEADVIEW) {
        //第二個頭佈局
        View view2 = mLayoutInflater.inflate(R.layout.recycle_secheadview, parent, false);
        //intSecRecycleData(view2);
        return new SecViewHolder(view2);
    }
    View view3 = LayoutInflater.from(parent.getContext()).inflate(R.layout.recycle_normalview, parent, false);
    VideoViewHolder vh = new VideoViewHolder(view3);
    return vh;
}

  @Override
    public void onBindViewHolder(RecyclerView.ViewHolder holder, final int position) {
        //第一個頭佈局
        if (isHeader(position)) {
           //相應數據綁定操作
            return;
            //第二個頭佈局
        } else if (isSec(position)) {
           //相應數據綁定
            
            return;
        }
        //常規佈局數據操作

	//由於添加了兩個頭佈局，在做數據綁定的時候要position-2纔是第一個數據源對應的item
    }

    private boolean isSec(int position) {
        return position == 1;
    }


    public boolean isHeader(int position) {
        return position == 0;
    }

RecycleView  adapter添加監聽器

public interface MyOnItemClickListener {
    void OnItemClick(View view, int position, int prentPosition, int viewid);
}

public void setOnItemClickListener(MyOnItemClickListener mOnItemClickListener) {
    this.mOnItemClickListener = mOnItemClickListener;
}

private MyOnItemClickListener onItemClickListener = new MyOnItemClickListener() {
    @Override
    public void OnItemClick(View view, int position, int prentPosition, int viewid) {

    }
};
