int color = Color.argb(a, 255, 90, 147);
ColorDrawable colorDrawable = new ColorDrawable();

ClipDrawable clipDrawable = new ClipDrawable(colorDrawable, Gravity.LEFT, ClipDrawable.HORIZONTAL);
Drawable drawable = getResources().getDrawable(R.color.transparent);
Drawable[] layers = new Drawable[]{drawable,clipDrawable};
LayerDrawable layerDrawable = new LayerDrawable(layers);
layerDrawable.setDrawableByLayerId(0,drawable);
layerDrawable.setDrawableByLayerId(1,clipDrawable);
progressBar.setProgressDrawable(clipDrawable);
progressBar.setProgress(0);
progressBar.setProgress(progress);
Loger.d("Vote投票", "result = " + progress);
Loger.d("Vote投票", "a = " + a);
