Question

I am a complete noob and I am trying to decrease the padding of an image over time with my code. I have this so far:

    public void growPotato() {
    long base = System.currentTimeMillis();
    long WorkingNum = 0;
    while(growing && WorkingNum > 5 ) {
        WorkingNum = 150 - ((System.currentTimeMillis() - base)/100);
        ImageView PotatoPicture = (ImageView) findViewById(R.id.imageView1);
        PotatoPicture.SetPadding(WorkingNum);
    }

I get an error on the line after ‘WorkingNum = 150 -‘ saying I am missing a ‘;’ for ‘LocalVariableDeclarationAssignment’. But my main problem is that I get the error: “The method SetPadding(long) is undefined for the type ImageView”… How can I work around or fix this?

Answer 1

Instead of:

PotatoPicture.SetPadding(WorkingNum);

you should call:

PotatoPicture.setPadding(WorkingNum, WorkingNum, WorkingNum, WorkingNum)

Java is case sensitive, so setPadding and SetPadding aren’t the same methods. Read API for more details: ImageView.setPadding(int, int, int, int).

In most Java naming conventions, local variables should start with lower case letter (or an underscore).
