Android ImageView setImageResource in code
提问by arielschon12
I have an imageView that i want to display a little icon of the country that you are currently in. I can get the country code, but problem is i can't dynamically change the imageView resource. My image files are all lowercase (Example: country code=US, image file=us)
我有一个 imageView，我想显示您当前所在国家/地区的小图标。我可以获得国家/地区代码，但问题是我无法动态更改 imageView 资源。我的图片文件都是小写的（例如：国家代码=美国，图片文件=我们）
My code (countryCode is the current countryCode in uppercase letters):
我的代码（countryCode 是当前的countryCode 大写字母）：
String lowerCountryCode = countryCode.toLowerCase();
String resource = "R.drawable." + lowerCountryCode;
img.setImageResource(resource);
Now, of course this will not work because setImageResource wants an int, so how can i do this? Thanks in advance :D
现在，这当然行不通，因为 setImageResource 需要一个 int，那么我该怎么做呢？提前致谢

One easy way to map that country name that you have to an intto be used in the setImageResourcemethod is:
映射您必须int在该setImageResource方法中使用的国家名称的一种简单方法是：
int id = getResources().getIdentifier(lowerCountryCode, "drawable", getPackageName());
setImageResource(id);
But you should really try to use different folders resources for the countries that you want to support.
但是您真的应该尝试为要支持的国家/地区使用不同的文件夹资源。

This is how to set an image into ImageViewusing the setImageResource()method:
这是ImageView使用setImageResource()方法设置图像的方法：
ImageView myImageView = (ImageView)v.findViewById(R.id.img_play);
// supossing to have an image called ic_play inside my drawables.
myImageView.setImageResource(R.drawable.ic_play);

you use that code
你使用那个代码
ImageView[] ivCard = new ImageView[1];
@override
protected void onCreate(Bundle savedInstanceState)
ivCard[0]=(ImageView)findViewById(R.id.imageView1);
