Showing an image without specifying src in xml

I want to show an image, depending on the value of the int imgch

This is in my onCreate:

    ImageView image = (ImageView)findViewById(R.id.gimage);
    Resources res = getResources();
    Drawable gameImage = res.getDrawable(images[imgch]);

And this in my XML:

     <ImageView
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:id="@+id/gimage" />

How do I get it to show the correct image in the activity?

Create an Array

int[] images;

on 

protected void onCreate(Bundle savedInstanceState) {

add this 

images = new int[3];
images[0] = R.drawable.first_image;
images[1] = R.drawable.second_image;
images[2] = R.drawable.third_image;

and then your code (where imgch is an integer)

...
Drawable gameImage = res.getDrawable(images[imgch]); 
...

Yes, but with java-side code

ImageView img = (ImageView) findViewById(R.id.gimage);
img.setImageDrawable(getDrawable(R.drawable.my_image_name));

If you wanna load from an remote url you may be use this

Check this ImageView#setImageDrawable. So you should have image.setImageDrawable(gameImage)
