Android: pass a resource id as a parameter

Question

I have this code:

translateRight("iv1"); //iv1 is an id of an imageView

    private void translateRight(String st){

    ImageView img = (ImageView)findViewById(R.id.st);
        Animation a = AnimationUtils.loadAnimation(this, R.anim.translate_right);
        img.startAnimation(a);
    }

I have "translateRight" that is a method that show an animation, but at this method I should pass a resource id; I tried with a string but it don't work, what can I do?

Solution 1

Resource id - is an integer value. Just pass an int:

private void translateRight(int resource){
    ImageView img = (ImageView) findViewById(resource);
    //stuff
}

Solution 2

Resource ID is an integer, not a String.

Solution 3

2. The second approach is that you directly pass the findViewById

   boolean tvStatus=status((CheckBox)findViewById(R.id.vn));

     public boolean status(CheckBox ch)
        {
   
            boolean ll=ch.isChecked() ;
            return  ll;
        }

By the way - it's more convinient to pass ImageView itself.

Just adding on to this answer, the function accepts any integer value right now. So, if you pass -13 or some arbitrary number, it will accept it and will try to find a view with that id. This can be handled by adding @IdRes annotation in the parameter. This will ensure that only a R.id type int is sent at compile time.
