Android处理视图圆角和色彩的工具类

Android代码处理视图圆角和色彩的工具类，供大家参考，具体内容如下

一直都用的.XML文件处理圆角与色彩或色彩渐变，觉得很不方便，后来发现了GradientDrawable这个类，就整了个工具类，用起来觉得挺方便

效果图：

下面贴代码：

public class DrawCorner {
 
 
 public static GradientDrawable drawCorner() {
 GradientDrawable drawable = new GradientDrawable();
 drawable.setCornerRadius(20);
 drawable.setColor(Color.WHITE);
 return drawable;
 }
 
 
 public static GradientDrawable drawCorner(int radius) {
 GradientDrawable drawable = new GradientDrawable();
 drawable.setCornerRadius(radius);
 drawable.setColor(Color.WHITE);
 return drawable;
 }
 
 
 public static GradientDrawable drawCorner(float[] radii) {
 if (radii == null || radii.length != 8) {
 radii = new float[]{0, 0, 0, 0, 0, 0, 0, 0};
 }
 GradientDrawable drawable = new GradientDrawable();
 drawable.setCornerRadii(radii);
 drawable.setColor(Color.WHITE);
 return drawable;
 }
 
 
 public static GradientDrawable drawCorner(int radius, int color) {
 GradientDrawable drawable = new GradientDrawable();
 drawable.setCornerRadius(radius);
 drawable.setColor(color);
 return drawable;
 }
 
 
 public static GradientDrawable drawCorner(float[] radii, int color) {
 if (radii == null || radii.length != 8) {
 radii = new float[]{0, 0, 0, 0, 0, 0, 0, 0};
 }
 GradientDrawable drawable = new GradientDrawable();
 drawable.setCornerRadii(radii);
 drawable.setColor(color);
 return drawable;
 }
 
 
 public static GradientDrawable drawCorner(int radius, int[] colors) {
 GradientDrawable drawable = new GradientDrawable();
 drawable.setCornerRadius(radius);
 drawable.setGradientType(GradientDrawable.LINEAR_GRADIENT);
 drawable.setColors(colors);
 return drawable;
 }
 
 
 public static GradientDrawable drawCorner(float[] radii, int[] colors) {
 if (radii == null || radii.length != 8) {
 radii = new float[]{0, 0, 0, 0, 0, 0, 0, 0};
 }
 GradientDrawable drawable = new GradientDrawable();
 drawable.setCornerRadii(radii);
 drawable.setGradientType(GradientDrawable.LINEAR_GRADIENT);
 drawable.setColors(colors);
 return drawable;
 }
 
 
 public static GradientDrawable drawCorner(int radius, int[] colors, int orientation) {
 GradientDrawable drawable = new GradientDrawable();
 drawable.setCornerRadius(radius);
 drawable.setGradientType(GradientDrawable.LINEAR_GRADIENT);
 switch (orientation) {
 case 0:
 drawable.setOrientation(GradientDrawable.Orientation.TOP_BOTTOM);
 break;
 case 1:
 drawable.setOrientation(GradientDrawable.Orientation.TR_BL);
 break;
 case 2:
 drawable.setOrientation(GradientDrawable.Orientation.RIGHT_LEFT);
 break;
 case 3:
 drawable.setOrientation(GradientDrawable.Orientation.BR_TL);
 break;
 case 4:
 drawable.setOrientation(GradientDrawable.Orientation.BOTTOM_TOP);
 break;
 case 5:
 drawable.setOrientation(GradientDrawable.Orientation.BL_TR);
 break;
 case 6:
 drawable.setOrientation(GradientDrawable.Orientation.LEFT_RIGHT);
 break;
 case 7:
 drawable.setOrientation(GradientDrawable.Orientation.TL_BR);
 break;
 }
 drawable.setColors(colors);
 return drawable;
 }
 
 
 public static GradientDrawable drawCorner(float[] radii, int[] colors, int orientation) {
 if (radii == null || radii.length != 8) {
 radii = new float[]{0, 0, 0, 0, 0, 0, 0, 0};
 }
 GradientDrawable drawable = new GradientDrawable();
 drawable.setCornerRadii(radii);
 drawable.setGradientType(GradientDrawable.LINEAR_GRADIENT);
 switch (orientation) {
 case 0:
 drawable.setOrientation(GradientDrawable.Orientation.TOP_BOTTOM);
 break;
 case 1:
 drawable.setOrientation(GradientDrawable.Orientation.TR_BL);
 break;
 case 2:
 drawable.setOrientation(GradientDrawable.Orientation.RIGHT_LEFT);
 break;
 case 3:
 drawable.setOrientation(GradientDrawable.Orientation.BR_TL);
 break;
 case 4:
 drawable.setOrientation(GradientDrawable.Orientation.BOTTOM_TOP);
 break;
 case 5:
 drawable.setOrientation(GradientDrawable.Orientation.BL_TR);
 break;
 case 6:
 drawable.setOrientation(GradientDrawable.Orientation.LEFT_RIGHT);
 break;
 case 7:
 drawable.setOrientation(GradientDrawable.Orientation.TL_BR);
 break;
 }
 drawable.setColors(colors);
 return drawable;
 }
 
}

调用方式很简单，就是

View.setBackground(DrawCorner.drawCorner);

就行了

例如：

TextView textView = findViewById(R.id.test);
textView.setBackground(DrawCorner.drawCorner());
