我想实现这样的目标：点击此处查看图片
圆形列表，可绘制，填充图像色调的浅色变体我试过textrdrawable库，但它没有给我同样的结果。我也尝试过以下代码，但没有成功：
public int darkenColor(int color) {
float[] hsv = new float[3];
Color.colorToHSV(color, hsv);
hsv[2] *= 0.8f; // value component
color = Color.HSVToColor(hsv);
return color;
}
public String[] mColors = {
"5E97F6",
"9CCC65",
"FF8A65",
"9E9E9E",
"9FA8DA",
"90A4AE",
"AED581",
"F6BF26",
"FFA726",
"4DD0E1",
"BA68C8",
"A1887F",
};
// all colors used by gmail application :)
浅色
// genrating random num from 0 to 11 because you can add more or less
int i1 = new Random().nextInt(11);
//genrating shape with colors
GradientDrawable draw = new GradientDrawable();
draw.setShape(GradientDrawable.OVAL);
draw.setColor(Color.parseColor ("#"+mColors[i1]));
// assigning to textview
contact_name_circle.setBackground(draw); //textview
