Android自定義進度條：SmoothProgressBar

一個小的Android庫，讓您擁有光滑，可定制水平不確定的進度條。

mProgressBar.setIndeterminateDrawable(new SmoothProgressDrawable.Builder(context)
    .color(0xff0000)
    .interpolator(new DecelerateInterpolator())
    .sectionsCount(4)
    .separatorLength(8)         //You should use Resources#getDimensionPixelSize
    .strokeWidth(8f)            //You should use Resources#getDimension
    .speed(2f)                 //2 times faster
    .progressiveStartSpeed(2)
    .progressiveStopSpeed(3.4)
    .reversed(false)
    .mirrorMode(false)
    .progressiveStart(true)
    .progressiveStopEndedListener(mListener) //called when the stop animation is over
    .build());

mProgressBar.setIndeterminateDrawable(new CircularProgressDrawable
    .Builder(this)
    .colors(getResources().getIntArray(R.array.gplus_colors))
    .sweepSpeed(1f)
    .strokeWidth(mStrokeWidth)
    .style(CircularProgressDrawable.Style.ROUNDED)
    [ ... ]
    .build();
