Consider I have two images image_name1.png, image_name2.png in drawable resources of android. Now I would like set image like below,
imageView.setImage(R.drawable.image_+"MyChoice"+.png);
where MyChoice can be name1 or name2 or some string
Is that possible, or do we have any solution to achieve that?
you can do by uri
String uri = "@drawable/imname"; //imname without extension
int imageResource = getResources().getIdentifier(uri, null, getPackageName()); //get image resource
Drawable res = getResources().getDrawable(imageResource); // convert into drawble
imageView.setImageDrawable(res); // set as image
Resources.getIdentifier does what you're looking for.
int resId = context.getResources().getIdentifier("image_"+myChoice, "drawable", "com.myapp.mypackage");
if(resId == 0) {
resId = R.drawable.default;
}
imageView.setImageResource(resId);
You can't do that. What you can do is something like:
int images[] = {R.drawable.image1, R.drawable.image2};
imageView.setImage(images[mychoice]);
Or something similar with a hash table if you want to do strings instead of integer indexes.
As an aside- you don't put the .png in the drawable name in code. THe point of drawable is that you shouldn't need to know if its png, jpg, or even xml.
there are two posibilties
1.
int MyChoice=1 or 2;
`imageView.setImage(R.drawable.image_+MyChoice+.png);`
second is
int image=Integer.parseInt("R.drawable.image_"+MyChoice+".png");
imageView.setImage(image);
