class ProductsAdapter extends BaseAdapter  {
    Context _scontext;
    LayoutInflater _inflater;
    ArrayList<ProductsDataModel> data;

    public ProductsAdapter(Context context,ArrayList<ProductsDataModel> arraylist) {
        this._scontext = context;
        data = arraylist;
    }
    @Override
    public int getCount() {
        return data.size();

    @Override
    public Object getItem(int position) {
        return null;

        ends_in.setText(s);
        discount_rate.setText(obj.getDiscount_text());

        String a="https:"+obj.getTeaser_url();      
        System.out.println("value of a is+"+a);

        AQuery aq = new AQuery(_scontext);
        aq.id(set_product_image).image(a);




        return itemView;
    }

您需要创建一个drawable并将其设置为背景视图的背景。

res / drawable中的

（你可能需要创建drawable文件夹）创建bubbleback.xml和添加以下代码

<?xml version="1.0" encoding="UTF-8"?> 
<shape xmlns:android="http://schemas.android.com/apk/res/android"> 
<solid android:color="#ffffffff"/>    

<stroke android:width="1dp"
        android:color="#ff000000"
        />

<padding android:left="3dp"
         android:top="3dp"
         android:right="3dp"
         android:bottom="3dp"
         /> 

<corners android:bottomRightRadius="10dp" 
         android:bottomLeftRadius="10dp" 
         android:topLeftRadius="10dp"
         android:topRightRadius="10dp"/> 
</shape>

保存并将friend_list_screen的最顶层视图的背景设置为冒泡drawable。
