android - 在 RecyclerView.ViewHolder 中以编程方式创建 View 并将参数传递给它

Question

我能否在 ViewHolder 中以编程方式创建 View ，而不是像所有示例中那样以经典方式从 XML 绑定(bind)它们？此外，我的 View 需要一个图像文件路径才能创建，我如何将其传递给 ViewHolder

protected static class ImagePreviewViewHolder extends RecyclerView.ViewHolder {
    public ImageView imageView;
    public LinearLayout page;

    public ImagePreviewViewHolder(View itemView) {
        super(itemView);
        page = createPage(filePath); // How do I pass the filepath?
    }
}

Answer 1

你试过创建吗 查看项目View通过代码？

例如:

ll = new LinearLayout(this);
ll.setOrientation(android.widget.LinearLayout.VERTICAL);
ll.setLayoutParams(new ViewGroup.LayoutParams(-1,-1));
ll.setBackgroundColor(0x88ff0000);

tv = new TextView(this);
tv.setLayoutParams(new ViewGroup.LayoutParams(-1,-2));
tv.setText("sample text goes here");
tv.setBackgroundColor(0x5500ff00);
ll.addView(tv);

和

ImagePreviewViewHolder holder = new ImagePreviewViewHolder(ll);
