Set imageview photo dynamically

Question

I have +300 png pictures.Their names are like; aaa.png abka.png bxja.png daw.png.

According to my setImage(String pictureName) function i want to set imageview View resource dynamically.

private void setImage(String pictureName){
      myImgView.setBackgroundResource(R.drawable + picturename);
}

My main idea is like this but as you can see it is imposible. What did i think to solve this problem is creating switch statemant for all +300 images but it will be really huge effort to implement this.

What am i asking is; is there a any easy way to implement this.

You should use this code, assuming that the function setImage is a member of activity

private void setImage(String pictureName)
{
     int id = getResources().getIdentifier(pictureName,"drawable",getPackageName());
     myImgView.setBackgroundResource(id);
}

R.drawable + picturename won't work because R.drawable.picturename is actually an integer that references your resource.

However, you can use Resources.getIdentifier to get that integer.

Then you can call setBackgroundResource() with the output
