我想創建一個國家和標誌選擇器。我想設置一個標誌的圖像，但我想根據它的名稱選擇該圖像。 BAscially我正在嘗試爲android創建一個標誌和ISD代碼選擇器，這樣我就可以在電話號碼用戶之前使用它來添加ISD代碼。如何通過Android中的名稱獲取圖像資源？
ImageView img1 = (ImageView)findViewById(R.id.imgFlag);
img1.setBackgroundResource(R.drawable.India_91);
在適配器中這樣的東西。
//India_91 is an image India_91.png,
//suppose if I have USA_1.png as image then i should be able to use
//string "USA_1" to get the related resource and set it as
//BackgroundResource.
@Override
public View getView(int position, View convertView, ViewGroup parent) {
long resId = getResourceIdUsingResourceString(arrayOfStrings[position]);
// I should get the Id of the image
// resource named as"USA_91"
}
//This is a utility function outside adapter class
long getResourceIdUsingResourceString(string resourceName){
//Here i want to add a code which can check for
//resource name and then get id of it
//which can then be used by callee function/block
//to fetch the correct resource and display it
}
