Load Images in ImageView in Android

Question

In my application....there are some images like temp1.jpg, temp2.jpg .....upto temp35.jpg,

so on button clicking, i want to load one-by-one image in ImageView .... i want to do like:

cnt=1;
imagename="temp" + cnt + ".jpg";
cnt++;

so my confusion is that "is there anyway to load an image in imageview from string(imagename variable) like temp1.jpg,etc."

Answer 1

You could try this:

int cnt = 1;
//Bitmap bitmap = BitmapFactory.decodeFile("temp" + cnt + ".jpg");
int imageResource = getResources().getIdentifier("drawable/temp" + cnt + ".jpg", null, getPackageName());
Bitmap bitmap = BitmapFactory.decodeResource(getResources(), imageResource);
imageView.setImageBitmap(bitmap);
cnt++;

Hope that's what you were looking for.

Answer 2

Why not something like

File f = new File(PathToFiles + "/temp" + cnt + ".jpg");
if (f.exists()) {
  Drawable d = Drawable.createFromPath(f);
  imageview.setImageDrawable(d);
}
