Android: How check if a image exists in a IF clause?

Issue

I need to know how check if an image exists in R.drawable, It has to be dynamic so I have to use a string that gives me the name of the image. I've tried with '!=null' or exist but it hasn't worked.... Help please!!!!!!!!!

titulo=bundle.getString("titulo");
textView = (TextView) findViewById( R.id.textView1);
textView.setText(titulo);
foto="f"+bundle.getString("numero")+"a";
System.out.println(foto);
flipper =(ViewFlipper) findViewById(R.id.vfFlipper);

this gives me the name of the image a need...

image = new ImageView(this);
image= new ImageView(this);
image.setImageResource(R.drawable.f00a1);
image.setScaleType(ScaleType.FIT_CENTER);
flipper.addView(image);

Whith this I can use the image but i need to use the variable "foto" so it can be dynamic Thanks!

Solution

you could use getResources to get an instance of Resources class. In Resources class, you have getDrawable If the resource is not found, you would get ResourceNotFoundException which also means the image is not found.

so the code will be something like this

Resource r = getResources();
Bool fileFound = true;
Drawable d = null;
try{
d = r.getDrawable(your_image_id);
}
catch(ResourceNotFoundException e){
fileFound = false;
}
if(findFound){
// Your operations
// set drawable to your imageview.
}
