Use it custom item view type

Show

Getting started

1. Entity must inherit MultiItemEntity

public class MultipleItem implements MultiItemEntity {
    public static final int TEXT = 1;
    public static final int IMG = 2;
    private int itemType;


    public MultipleItem(int itemType, String content) {
        this.itemType = itemType;
    }

    public MultipleItem(int itemType) {
        this.itemType = itemType;
    }

    @Override
    public int getItemType() {
        return itemType;
    }
}

2. binding itemType with layout

public class MultipleItemQuickAdapter extends BaseMultiItemQuickAdapter<MultipleItem> {

    public MultipleItemQuickAdapter(List data) {
        super(data);
        addItemType(MultipleItem.TEXT, R.layout.text_view);
        addItemType(MultipleItem.IMG, R.layout.image_view);
    }

    @Override
    protected void convert(BaseViewHolder helper, MultipleItem item) {
        switch (helper.getItemViewType()) {
            case MultipleItem.TEXT:
                helper.setImageUrl(R.id.tv, item.getContent());
                break;
            case MultipleItem.IMG:
                helper.setImageUrl(R.id.iv, item.getContent());
                break;
        }
    }

}

If there are multiple layout item two rows layout is the same, as shown:

Through the above picture, we can see that the second line is the third line item also ImageView, this time ImageView can be reused, we can use GridLayoutManager

 multipleItemAdapter.setSpanSizeLookup(new BaseQuickAdapter.SpanSizeLookup() {
            @Override
            public int getSpanSize(GridLayoutManager gridLayoutManager, int position) {
                return data.get(position).getSpanSize();
            }
        });

By rewriting his SapnSize reuse ImageView. Suppose GridLayoutManager of spanCount is 3, then the first, second, item 3 of spanSize is because to occupy a line (and weight similar meaning), then the third, fourth, fifth, item of spanSize It is 1.
