Android 能否将两种类型的项目添加到stggeredListView？

我的应用程序使用

com.etsy.android.grid.edgridview

我有一个适配器，它用一个自定义项填充交错网格。现在我想向该网格添加另一个自定义项。这能做到吗

我有2个自定义项XML和2个LayoutAdapter。如何将这两个项都添加到Edgrid中？我尝试使用AddVew，但它在视图中不可用。也许我应该只使用1个适配器

我会把代码控制在最低限度，但如果你想看更多的话，我会问你

基于您正在尝试解决的问题的类型，一个很好的替代选择是考虑利用Debug GrIDLayOutMaultReaveReVIEW，并定制适配器以2个或更多个（如果需要的类型的浏览器）工作，允许它们中的每一个拥有它自己的布局。 更新：

@Override
public View getView(final int position, View convertView, final ViewGroup parent) {
    if(getItemViewType(position) == 1) {
        // work with ViewHolderTypeOne
    } else if(getItemViewType(position) == 2) {
        // work with ViewHolderTypeTwo
    }
}

@Override
public int getItemViewType(int i) {
    // View Types: 1 - view type one, 2 - view type two, determined by position i in grid
    if(i == 0) {
        return 1;
    } else {
        return 2;
    }
}

class ViewHolderTypeOne extends ViewHolder {
    public viewOneAttrOne;
    public viewOneAttrTwo;
}

class ViewHolderTypeTwo extends ViewHolder {
    public viewTwoAttrOne;
    public viewTwoAttrTwo;
    public viewTwoAttrThree;
}

我得到了一个答案，不一定是最好的答案，所以我会让它打开一点

我将新的项目xml控件合并到旧的项目xml控件中，因此只有一个，然后我确定在将项目添加到网格时要显示哪些控件。给人的印象是一个网格中有两个不同的项目…在将项目添加到页面时…我向字符串数组添加了一个新元素，该数组将触发要构建的新项目xml-我认识到这个新元素希望显示不同的控件，因此我将原始控件视为不可见，将新控件视为可见

    if (tileControlValues[0].equals("controls"))
    {
        vh.layout_summary.setVisibility(View.INVISIBLE);
        vh.layout_controls.setVisibility(View.VISIBLE);
    }
    else
    {
        vh.summary_header.setText(tileControlValues[0]);
        vh.summary_subheader.setText(tileControlValues[1]);
        vh.summary1_label.setText(tileControlValues[2]);
        vh.summary1_value.setText(tileControlValues[3]);
        vh.summary2_label.setText(tileControlValues[4]);
        vh.summary2_value.setText(tileControlValues[5]);

哦，亲爱的，我的方式太深了，回收器视图不是一个简单的通道。例如：有没有使用交错视图我可以做到这一点-我目前正在研究一个适配器，它在等待切换时引用一个项目xml或其他。你能不能也显示TileAdapter_摘要类的内容？当然。。。接下来……如果您想要我的sumary布局xml和新的布局xml，请告诉我；'controls’我现在考虑在适配器中使用一个开关，并根据活动传递的开关指向diff xms，但这并没有帮助，因为我只初始化了适配器一次，所以永远不会添加第二项。我想在添加了摘要图块之后，将新自定义视图的一个实例添加到网格中。我想我可以合并视图；显示我想要的内容并隐藏其他内容以提供2个视图的外观，但这不是很令人满意。更新此内容，将可见性设置为View.Gone，以完全释放用于您想要不可见的控件的空间。
