Android(安卓)progressBar代码设置进度条颜色、背景颜色以及圆角显示

效果如下：

Java代码设置如下：

int roundRadius = 15; // 8dp 圆角半径 The x-radius of the oval used to round the corners//准备progressBar带圆角的背景DrawableGradientDrawable progressBg = new GradientDrawable();//设置圆角弧度progressBg.setCornerRadius(roundRadius); //设置绘制颜色progressBg.setColor(getResources().getColor(R.color.color_efefef));//准备progressBar带圆角的进度条DrawableGradientDrawable progressContent = new GradientDrawable();progressContent.setCornerRadius(roundRadius);//设置绘制颜色，此处可以自己获取不同的颜色progressContent.setColor(getColorForIndex(position));//ClipDrawable是对一个Drawable进行剪切操作，可以控制这个drawable的剪切区域，以及相相对于容器的对齐方式ClipDrawable progressClip = new ClipDrawable(progressContent, Gravity.LEFT, ClipDrawable.HORIZONTAL);//Setup LayerDrawable and assign to progressBar//待设置的Drawable数组Drawable[] progressDrawables = {progressBg, progressClip};LayerDrawable progressLayerDrawable = new LayerDrawable(progressDrawables);//根据ID设置progressBar对应内容的DrawableprogressLayerDrawable.setId(0, android.R.id.background);progressLayerDrawable.setId(1, android.R.id.progress);//设置progressBarDrawableprogressBar.setProgressDrawable(progressLayerDrawable);//设置进度值progressBar.setProgress(item.getValue());
