How can I get image's name?

Question

I want to make a function which debug when image's name equal "aaa". So I think that I should get image's name.

for example, there is a ImageView.

ImageView img1 = (ImageView) findViewById(R.drawable.button);

public void passMSg(){
   if(name == "button"){ // "name" means image's name. = button
      Toast. ~
   }

I find other questions. But I can't understand and I think that is not answer which I want. Who can help me?

Answer 1

if your image is a file like 'aaa.jpg/png..'

try to use the APIs of String such as subString().indexOf()

and your code may be like this:

int index = name.indexOf(".");

String name = name.subString(name,0,index);
