Android progressBar代码设置进度条颜色、背景颜色以及圆角显示_android progressbar设置背景两边及进度显示圆角

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Drawable
GradientDrawable 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Drawable
GradientDrawable 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Drawable
progressLayerDrawable.setId(0, android.R.id.background);
progressLayerDrawable.setId(1, android.R.id.progress);
//设置progressBarDrawable
progressBar.setProgressDrawable(progressLayerDrawable);
 
//设置进度值
progressBar.setProgress(item.getValue());
