Question

您好我正在使用Android自定义网格视图。我有一个带有图像视图，文本视图的自定义网格项。当我点击图像视图时它会改变它的颜色。它工作得很好。但是我有一个问题

图像视图在网格视图滚动时更改状态
当我点击图片视图时，另一个图片视图也会改变其状态。

我使用了代码

  public class CustomGrid extends BaseAdapter{
    private Context mContext;
    private final String[] web1;
   private final int[] Imageid; 

    public CustomGrid(Context c,String[] web,int[] Imageid ) {
        mContext = c;
        this.Imageid = Imageid;
        this.web1 = web;
    }

    @Override
    public int getCount() {

        return web1.length;
    }

    @Override
    public Object getItem(int position) {

        return null;
    }

    @Override
    public long getItemId(int position) {

        return 0;
    }


    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
         final ImageView button01;
        View v;
        if (convertView == null) {  // if it's not recycled, initialize some attributes
            LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(     Context.LAYOUT_INFLATER_SERVICE );
            v = inflater.inflate(R.layout.grid_single, parent, false);

        } else {
            v = convertView;
        }
        TextView text = (TextView)v.findViewById(R.id.grid_text);
        text.setText(web1[position]);
        ImageView image = (ImageView)v.findViewById(R.id.grid_image);

        image.setBackgroundResource(Imageid[position]);
         button01 = (ImageView)v.findViewById(R.id.star);
        button01.setOnClickListener(new OnClickListener() {
            int button01pos = 0;
            public void onClick(View v) {
                if (button01pos == 0) {
                    button01.setImageResource(R.drawable.star);
                    button01pos = 1;
                } else if (button01pos == 1) {
                    button01.setImageResource(R.drawable.startclicked);
                    button01pos = 0;
                }
            }
        });
        return v;
    }
   }

以这种方式试试......

创建另一个数组来存储button01pos的值，初始值为{0,0,0,0 ...};

     public class CustomGrid extends BaseAdapter{
     private Context mContext;
     private final String[] web1;
     private final int[] Imageid; 
     private final int[] button01pos;

    public CustomGrid(Context c,String[] web,int[] Imageid, int[] button01pos ) {
        mContext = c;
        this.Imageid = Imageid;
        this.web1 = web;
        this.button01pos=button01pos;
    }

然后在getview（）方法中，添加此项，

if (button01pos[position] == 0) {
                    button01.setImageResource(R.drawable.star);

                } else if (button01pos == 1) {
                    button01.setImageResource(R.drawable.startclicked);

                }

button01.setOnClickListener(new OnClickListener() {

            public void onClick(View v) {
                if (button01pos[position] == 0) {
                    button01.setImageResource(R.drawable.star);
                    button01pos[position] = 1;
                } else if (button01pos[position] == 1) {
                    button01.setImageResource(R.drawable.startclicked);
                    button01pos[position] = 0;
                }
            }
        });
