A ProgressBar is a child of View. Activity is not, but it can contain one or more ViewGroups made up of one or more Views.
Create a subclass of ProgressBar
and then include it in the View that is rendered by the Activity
.
Domanda
I want to edit onDraw
method for my progressbar. But in my class I use extends
to Activity
class. When I search on the internet I see , I should extend to ProgressBar
class. But I etends activity so How can I implements ProgressBar class?
my reason: I want to use progress bar which is filling right to left.
my code :
@Override
protected void onDraw(Canvas canvas) {
canvas.save();
canvas.rotate(180,MainActivity.phone_width/2,MainActivity.phone_height/2);
super.onDraw(canvas);
canvas.restore();
}
