My Question is how to change image id from drawable folder in setImageResource() in android.
My drawable folder contains icon0.png to icon9.png and i want to change these images in image view dynamically using this

 ImageView iV3;
iV3 = (ImageView) findViewById(R.id.imageView3);
iV3.setImageResource(R.drawable.icon + speed_Arr[2]);

speed_Arr[2] contains any value from 0 – 9.
But this didnt change images.
Plz help me out.

Answer 1

public static int getIdentifier(Context context, String name)
{
    return context.getResources().getIdentifier(name.substring(0, name.lastIndexOf(".")), "drawable", context.getPackageName());
}

Above code will return the resource id from name String.
