ListView多重布局

话不多说，直接上代码

public class MyAdapter extends BaseAdapter {

    List<Object> list = new ArrayList<>();
    Context context = null;

    LayoutInflater inflater = null;

    public MyAdapter(Context context, List<Object> list) {
        this.context = context;
        this.list = list;

        inflater = LayoutInflater.from(context);
    }

    /**
     * 确定整个ListView一共会有多少个item
     */
    @Override
    public int getCount() {
        return list.size();
    }

    /**
     * 根据position从数据源中取数据对象
     */
    @Override
    public Object getItem(int position) {
        return list.get(position);
    }

    /**
     * 判定接下来的item是哪种类型
     */
    @Override
    public int getItemViewType(int position) {
        return position % 3;
    }

    /**
     * 所有item一共分为几类
     */
    @Override
    public int getViewTypeCount() {
        return 3;
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {

        ViewHolderBase holder = null;

//        确定将要绘制的item是哪种类型
        int viewType = getItemViewType(position);

        switch (viewType) {
            case 0:
                if (convertView == null) {
                    convertView = inflater.inflate(R.layout.item_layout0);
                    holder = new ViewHolder1(convertView);
                } else {
                    holder = (ViewHolder1) convertView.getTag();
                }

                inflateItem0(list.get(position), (ViewHolder0) holder);

                break;

            case 1:
                break;

            case 2:
                break;
        }
        return convertView;
    }

    private void inflateItem0(Object o, ViewHolder0 holder) {
        holder.txtCommon.setText("xxx");
        holder.myBtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                
            }
        });
    }

    private void inflateItem1(Object o, ViewHolder1 holder) {
    }

    private void inflateItem2(Object o, ViewHolder2 holder) {
    }

    abstract class ViewHolderBase {
        //三种holder共有的属性可以提取到父类
        @Bind(R.id.txtCommon)
        TextView txtCommon;

        public ViewHolderBase(View view) {
            ButterKnife.bind(this, view);
        }
    }

    class ViewHolder0 extends ViewHolderBase {

        @Bind(R.id.myBtn)
        Button myBtn;

        public ViewHolder0(View view) {
            super(view);
        }
    }

    class ViewHolder1 extends ViewHolderBase {

        @Bind(R.id.imageview)
        ImageView imageview;

        public ViewHolder1(View view) {
            super(view);
        }
    }

    class ViewHolder2 extends ViewHolderBase {
        public ViewHolder2(View view) {
            super(view);
        }
    }
}

体会getItemViewType和getViewTypeCount的作用。
另外，引入一个库，ButterKnife。
