Question

The method Picture receives a random int i. I want to add i to the R.drawable.pic+i
in order to randomly choose between several drawables in the resource folder (pic0,pic1,pic2,…) and set them as background at the end of the view k. How can I do it? Here’s the code I have now:

public void Picture(int i){
    View k = new View(NewGame.this);
    k.setBackgroundResource(R.drawable.pic); 
    // here it should be k.setBackgroundResource(R.drawable.pic1); for example
    setContentView(k);
}

Answer 1

the code that worked for me is :

public void Picture(int i){

View k = new View(NewGame.this);

setContentView(k);

int resourceId=getResources().getIdentifier("pic"+i, "drawable",getPackageName()); 

k.setBackgroundResource(resourceId);
}
