 public View getView(int position, View convertView, ViewGroup parent) {
         LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
         View grid=inflater.inflate(R.layout.griditem, parent, false);
         imageView=(ImageView)grid.findViewById(R.id.grid_prod);
         imageView.setImageResource(imgId[position]);
         imgoff =(ImageView)grid.findViewById(R.id.offer);
         tv=(TextView)grid.findViewById(R.id.grid_text);
         tv.setText(namesArr[position]);
         tv.setTextColor(Color.BLACK);
        rb=(RatingBar)findViewById(R.id.grid_rating);
         rb.setRating(rateFArr[position]);
            return grid;
        }

我在 GridView 中插入了一个评分栏，当我在这里使用 setRating 时，应用程序被强制关闭。这rateFArr[]是一个浮点数组，当我在此处打印值时，它会变得很正式。当我将它设置为评级栏时，它仍然无法正常工作。

请提前帮我解决这个问题。

我无法设置评级......现在我通过制作我自己的评级栏来解决它，其中有 5 个图像视图，每个图像视图的默认图像为空星，并根据我得到的评级，我用半填充星图像或全填充填充它星形图像或将其留空。这是我做的代码......

 public View getView(int position, View convertView, ViewGroup parent) {
     LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
     View grid=inflater.inflate(R.layout.griditem, parent, false);
     imageView=(ImageView)grid.findViewById(R.id.grid_prod);
     imageView.setImageResource(imgId[position]);
     imgoff =(ImageView)grid.findViewById(R.id.offer);
     tv=(TextView)grid.findViewById(R.id.grid_text);
     tv.setText(namesArr[position]);
     tv.setTextColor(Color.BLACK);
     tv.setPadding(0, 2, 0, 0);
   sta=(ImageView)grid.findViewById(R.id.imageView);
    sta1=(ImageView)grid.findViewById(R.id.imageView1);
    sta2=(ImageView)grid.findViewById(R.id.imageView2);
    sta3=(ImageView)grid.findViewById(R.id.imageView3);
    sta4=(ImageView)grid.findViewById(R.id.imageView4);
    Float rate=rateFArr[position];


   if(rate==5 || rate==4.5)
    {
        sta.setImageResource(R.drawable.full__small);
        sta1.setImageResource(R.drawable.full__small);
        sta2.setImageResource(R.drawable.full__small);

        else
        {

        }
    }
    if(rate==2 || rate==1.5)

    {
        if(rate==1)
        sta.setImageResource(R.drawable.full__small);
        else
            sta.setImageResource(R.drawable.half_small);

    }
    if(rate>5)
    {
        sta.setImageResource(R.drawable.full__small);
        sta1.setImageResource(R.drawable.full__small);
        sta2.setImageResource(R.drawable.full__small);
        sta3.setImageResource(R.drawable.full__small);
        sta4.setImageResource(R.drawable.full__small);
    }

    // rb=(RatingBar)findViewById(R.id.grid_rating);
     //rb.setRating(rateFArr[position]);
        return grid;
    }
