我正在使用下面的列表来实现RecyvlerView。我已经使用了StaggeredGridLayoutManager

在此处输入图像描述.

注意:此屏幕截图与GAP_HANDLING_MOVE_ITEMS_BETWEEN_SPANS

一切正常,但问题在于物品排列的顺序,它排列的物品如下:

 | 0 | 1 |
 | 3 | 2 |
 | 4 | 5 |
 | 7 | 6 |

如果您检查上图,您会注意到第二个项目在右侧绘制,而第四个项目在左侧,但我的要求是从右侧开始每一行,即第四个项目将出现在网格的右侧。我已经尝试过 GapStrategyStaggeredGridLayoutManager.GAP_HANDLING_MOVE_ITEMS_BETWEEN_SPANSStaggeredGridLayoutManager.GAP_HANDLING_NONE. 如果我使用GAP_HANDLING_NONE,则项目不可见,但调用适配器的功能但输出为空白屏幕。是否有任何功能可以强制 StaggeredGridLayoutManager 从右侧开始绘制新行?

我正在使用以下代码计算项目高度:

public static void isSquired(View view, int position) {
        DisplayMetrics displayMetrics = new DisplayMetrics();
        ((Activity) view.getContext()).getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);
        int height = displayMetrics.heightPixels;
        int width = displayMetrics.widthPixels;
        boolean isSquare = isSquare(position);
        ViewGroup.LayoutParams lp = view.getLayoutParams();
        if (isSquare) {
            lp.width = width / 2;
            lp.height = width / 2;
        }else{
            lp.width = width / 2;
            lp.height = (width / 2)+70;
        }

        view.setLayoutParams(lp);
        view.requestLayout();
    }

    public static boolean isSquare(int position) {
        int mod = position % 4;
        return mod == 1 || mod == 3;
    }
      

RecyclerView 初始化:

StaggeredGridLayoutManager manager = new StaggeredGridLayoutManager(2, StaggeredGridLayoutManager.VERTICAL);
//manager.setGapStrategy(StaggeredGridLayoutManager.GAP_HANDLING_NONE);
manager.setGapStrategy(StaggeredGridLayoutManager.GAP_HANDLING_MOVE_ITEMS_BETWEEN_SPANS);
recyclerView.setLayoutManager(manager);
recyclerView.setNestedScrollingEnabled(false);
