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
One easy way to map that country name that you have to an int
to be used in the setImageResource
method is:
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.
you use that code
ImageView[] ivCard = new ImageView[1];
@override
protected void onCreate(Bundle savedInstanceState)
ivCard[0]=(ImageView)findViewById(R.id.imageView1);
You can use this code:
// Create an array that matches any country to its id (as String):
String[][] countriesId = new String[NUMBER_OF_COUNTRIES_SUPPORTED][];
// Initialize the array, where the first column will be the country's name (in uppercase) and the second column will be its id (as String):
countriesId[0] = new String[] {"US", String.valueOf(R.drawable.us)};
countriesId[1] = new String[] {"FR", String.valueOf(R.drawable.fr)};
// and so on...
// And after you get the variable "countryCode":
int i;
for(i = 0; i<countriesId.length; i++) {
if(countriesId[i][0].equals(countryCode))
break;
}
// Now "i" is the index of the country
img.setImageResource(Integer.parseInt(countriesId[i][1]));
This is how to set an image into ImageView
using the setImageResource() method:
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 may try this:-
myImgView.setImageDrawable(getResources().getDrawable(R.drawable.image_name));
