使用ImageView的ArrayList中的Andr​​oid加载图像 [英] Android Load image on ImageView using arraylist

问题描述

这可能是我可能会再次忽略了一个问题，但如果你能帮助我解决这个问题，我将非常感激。
使用这种code，以获得可绘制的图像，并把它发送到Imageview.setImageResource（其中我的ImageView是一个gridview内）;一切正常

 私人整数[] = imageIDs {
            //R.drawable.image1，
            R.drawable.image2，
            R.drawable.image3，
            R.drawable.image4，
            R.drawable.image5，
            R.drawable.image6，
            R.drawable.Image7，
};//这里是我的另一个code调用imageIDs为ImageResource
ImageView的IV =（ImageView的）v.findViewById（R.id.grid_item_picture）;
iv.setImageResource（imageIDs [位置]）;
//位置的GridView的从0开始的默认值
 

现在我要完成的是删除阵列，并将其转换，因为需要这些数据里面是动态的简单的ArrayList。所以，香港专业教育学院创建这些新的code

 的ArrayList＆LT;串GT; array_image =新的ArrayList＆LT;串GT;（）;
        array_image.add（R.drawable.image6）;
        array_image.add（R.drawable.image1）;
 

和ImageView的ImageResource设置为此code

  iv.setImageResource（array_image获得（位置））;
 

我收到一个错误说：

  

在类型ImageView的方法setImageResource（INT）是不适用的参数（对象）
  你能不能帮我解决/看着办吧？

解决方案

您正在定义弦乐的ArrayList。但是你需要整数作为资源标识符。

做到这一点，而不是像这样;

 的ArrayList＆LT;整数GT; array_image =新的ArrayList＆LT;整数GT;（）;
array_image.add（R.drawable.image6）;
array_image.add（R.drawable.image1）;
 

This might be a problem that I might overlooked again but if you could help me solve it, I will be very thankful. Using this code to get images from drawable and sending it to Imageview.setImageResource (in which my Imageview is inside a gridview);everything works well

private   Integer[] imageIDs = {
            //R.drawable.image1,
            R.drawable.image2,
            R.drawable.image3,
            R.drawable.image4,
            R.drawable.image5,
            R.drawable.image6,
            R.drawable.Image7,
};

//Here is my another code to call imageIDs as ImageResource
ImageView iv = (ImageView)v.findViewById(R.id.grid_item_picture);
iv.setImageResource(imageIDs[position]);
//position is a default value of gridview starting from 0 

Now what I trying to accomplish is to delete that array and convert it to arraylist simply because need these inside data to be dynamic. And so ive created these new code

ArrayList<String> array_image = new ArrayList<String>();
        array_image.add("R.drawable.image6");
        array_image.add("R.drawable.image1");

and set the ImageView ImageResource to this code

iv.setImageResource(array_image .get(position));

I am getting an error saying:

The method setImageResource(int) in the type ImageView is not applicable for the arguments (Object) Can you help me fix/figure it out?

解决方案

You are defining an ArrayList for Strings. However you need integers as resource identifiers.

Do it instead like this;

ArrayList<Integer> array_image = new ArrayList<Integer>();
array_image.add(R.drawable.image6);
array_image.add(R.drawable.image1);
