My purpose to use opacity with Image view because i put it in splash screen. I want the imageview start up from opacity 0 to 100 percents.

```
    imageView=(ImageView) findViewById(R.id.imvLogo);

    for (int i=1;i<11;i++){

        for (int j=1;j<1000;j++){
        }
        imageView.getBackground().setAlpha(10*i);
    }

```

i think the opacity will increase more and more by for loop but the result not like i think. so anyone have any idea?
sorry if this question doesn't make sense!
