示例1: rotatedOval
import android.graphics.Path; //导入方法依赖的package包/类
private Bitmap rotatedOval(Bitmap bitmap) {
Bitmap bmp;
float width = bitmap.getWidth();
float height = bitmap.getHeight();
bmp = Bitmap.createBitmap((int) width, (int) height, Bitmap.Config.ARGB_8888);
BitmapShader shader = new BitmapShader(bitmap, BitmapShader.TileMode.CLAMP, BitmapShader.TileMode.CLAMP);
Canvas canvas = new Canvas(bmp);
Paint paint = new Paint();
paint.setAntiAlias(true);
paint.setShader(shader);
Path oval = new Path();
Matrix matrix = new Matrix();
RectF ovalRect = new RectF(width / OVAL_FACTOR, 0, width - (width / OVAL_FACTOR), height);
oval.addOval(ovalRect, Path.Direction.CW);
matrix.postRotate(ROTATION, width / 2, height / 2);
oval.transform(matrix, oval);
canvas.drawPath(oval, paint);
return bmp;
}
示例2: onDraw
import android.graphics.Path; //导入方法依赖的package包/类
/**
* Path同样也给我们封装好了一些路径效果，例如圆形，矩形等等，跟canvas.drawXX比较类似，这里就简单介绍下
*
* addArc(float left, float top, float right, float bottom, float startAngle, float sweepAngle)
* 添加弧线到路径
*
* addCircle(float x, float y, float radius, Path.Direction dir) 添加圆到路径
*
* addOval(float left, float top, float right, float bottom, Path.Direction dir) 添加椭圆到路径
*
* addRect(float left, float top, float right, float bottom, Path.Direction dir) 添加矩形到路径
*
* 上面的Path.Direction dir参数用来指定绘制时是顺时针还是逆时针，Path.Direction.CCW和Path.Direction.CW分别代表逆时针和顺时针，
* 顺时针和逆时针主要的作用在于不同的时针方向也就决定了不同的路径起始点和终点，其他的参数跟canvas.drawXX是一样的
