如果Android RecyclerView的宽度超过屏幕，可以尝试以下解决方法：

1. 设置RecyclerView的宽度为屏幕宽度的一部分：

RecyclerView recyclerView = findViewById(R.id.recyclerView);
int screenWidth = getResources().getDisplayMetrics().widthPixels;
int recyclerViewWidth = (int) (screenWidth * 0.8); // 80% of screen width
recyclerView.setLayoutParams(new LinearLayout.LayoutParams(recyclerViewWidth, LinearLayout.LayoutParams.WRAP_CONTENT));

2. 使用LayoutManager来限制RecyclerView的宽度：

RecyclerView recyclerView = findViewById(R.id.recyclerView);
LinearLayoutManager layoutManager = new LinearLayoutManager(this);
layoutManager.setOrientation(LinearLayoutManager.HORIZONTAL); // 设置为横向布局
recyclerView.setLayoutManager(layoutManager);
recyclerView.setHasFixedSize(true);

3. 使用自定义的ItemDecoration来限制每个Item的宽度：

public class ItemSpacingDecoration extends RecyclerView.ItemDecoration {
    private int spacing;

    public ItemSpacingDecoration(int spacing) {
        this.spacing = spacing;
    }

    @Override
    public void getItemOffsets(Rect outRect, View view, RecyclerView parent, RecyclerView.State state) {
        super.getItemOffsets(outRect, view, parent, state);
        outRect.left = spacing;
        outRect.right = spacing;
    }
}

// 在使用RecyclerView时添加ItemDecoration
ItemSpacingDecoration itemSpacingDecoration = new ItemSpacingDecoration(10);
recyclerView.addItemDecoration(itemSpacingDecoration);

请注意，上述代码示例可能需要根据实际情况进行适当调整。
