如何实现多个“图像添加”布局？
我想在我的数据库中上传多个图像。我的问题是如何在屏幕下方设计上传多张图片。
首先：添加第一张图片的选项：
添加一张图片后，添加选项应向右移动：
添加3张图片后，添加选项应移至第2行的左侧：
如何设计在添加3张图像后将在第2行移动的布局。请帮助设计上面的布局。先感谢您。

LinearLayout gallery = getView().findViewById(R.id.gallery);
LayoutInflater inflater = LayoutInflater.from(getContext());
View view =inflater.inflate(R.layout.item_camera, gallery,false);
TextView textView =view.findViewById(R.id.textView);
textView.setText("Image" +value);
ImageView imageView =view.findViewById(R.id.imageView);
imageView.setImageBitmap(image);
gallery.addView(view);
