int
a = progress *

int
color = Color.argb(a,

);
ColorDrawable colorDrawable =
new
ColorDrawable();
colorDrawable.setColor(color);
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 = "
