java - 按钮中的按钮 (android.content.Context) 无法应用于 (Java.lang.Object)

Question

我正在尝试动态创建按钮以匹配数据表。我正在使用这个answer作为引用点，但我不断收到此错误代码: Button (android.content.Context) in Button Cannot be Applied to (Java.lang.Object)我尝试了多种方法来缓解错误代码，但我不知道如何修复它，我尝试将 map 设置为数组，但这也不起作用。代码已成功计数并显示数据，但我无法让它添加所需的按钮。

 Backendless.Data.of( "Store" ).find( queryBuilder, new AsyncCallback<List<Map>>()
                {
                    @Override
                    public void handleResponse( List<Map> response )
                    {

                       int numBrands = response.size();

                       Button brandButtons[] = new Button[numBrands];

          System.out.println("The Count of Buttons:" + numBrands);

           ArrayList<Brands> productList  = new ArrayList<>();



             Object[] arrayList = {response};
            for(int i = 0; i < brandButtons.length; i++)
                        {

                        Button brans = new Button(productList[i]);

                            brans.setOnClickListener();
                            add(brans);
                            brandButtons[i] = brans;




                            //Object element = thisIsAStringArray[i];
                            System.out.println( "List of Brands" + response );




                        }

                    }

Answer 1

您的错误在这一行:

Button brans = new Button(productList[i]); // here

Button类需要 Context 传递给它的构造函数调用，而您正在传递 Object 类型。

像这样使用，

Button brans = new Button(context); // here context can be activity or fragment.

//now use this brans object to set property to your programmatically created Button, 
//don't forget to add it to your parent view afterwards
