Question

我与颜色和图像有关，

每种产品都有颜色，每种颜色都有图像和图标

这是来自数据库的响应：

@Override
    public void onBindViewHolder(final SimpleViewHolder viewHolder, final int position) {

        int rowPos  = viewHolder.getAdapterPosition ();


            final String item = String.valueOf (operatorlist.get (position));

            String[] strArray = new String[]{item};
            System.out.println (strArray);
           viewHolder.tvEmail.setText (strArray[0]);
//           viewHolder.tvName.setText (strArray[1]);
//           String[] strArray1=new String[]{String.valueOf (strArray)};;
//            for (int i=0;i<strArray.length;i++){
//                strArray1=strArray;
//
//
//               // viewHolder.tvEmail.setText (strArray1[1].get());
//
//            }
          //  System.out.println (strArray[1]); //prints "name"

           // viewHolder.tvName.setText ((strArray[3]));
      //  viewHolder.tvEmail.setText (strArray[0]);
           // viewHolder.txtRank.setText (strArray[1]);


            viewHolder.swipeLayout.setShowMode (SwipeLayout.ShowMode.PullOut);

            // Drag From Left
            viewHolder.swipeLayout.addDrag (SwipeLayout.DragEdge.Left, viewHolder.swipeLayout.findViewById (R.id.bottom_wrapper1));

            // Drag From Right
            viewHolder.swipeLayout.addDrag (SwipeLayout.DragEdge.Right, viewHolder.swipeLayout.findViewById (R.id.bottom_wrapper));


            // Handling different events when swiping
            viewHolder.swipeLayout.addSwipeListener (new SwipeLayout.SwipeListener ( ) {
                @Override
                public void onClose(SwipeLayout layout) {
                    //when the SurfaceView totally cover the BottomView.
                }

                @Override
                public void onUpdate(SwipeLayout layout, int leftOffset, int topOffset) {
                    //you are swiping.
                }

                @Override
                public void onStartOpen(SwipeLayout layout) {

                }

                @Override
                public void onOpen(SwipeLayout layout) {
                    //when the BottomView totally show.
                }

                @Override
                public void onStartClose(SwipeLayout layout) {

                }

                @Override
                public void onHandRelease(SwipeLayout layout, float xvel, float yvel) {
                    //when user's hand released.
                }
            });

如何创建HTML表单来添加此信息？

，以及如何发布使用控制器按颜色分组的这些图像？

Answer 1

<input type="text" name="id"/>
<input type="text" name="name"/>
<input type="text" name="colors[id][]"/>
<input type="text" name="colors[stocks_id][]"/>
<input type="text" name="colors[color_name][]"/>
<input type="text" name="colors[icon][]"/>
<input type="text" name="colors[images][$n+1][]"/>

在控制器中

$colors= [];
$index= 0;
// colors[id] = [0=>1, 1=>2];
// colors[stocks_id] = [0=>234, 1=>289];

foreach($request['colors'] as $key => $color){ 

    if(!isset($colors[$index])){
       $colors[] = [];
    }

    if(!isset($colors[$index][$key])){
       $colors[$index][$key] = $color[$index];
    }

    $index++;
}

应该有一个循环来迭代颜色，并且有另一个循环来迭代关于该颜色的所有图像。
