示例1: rotatedOval
import android.graphics.Path; //導入方法依賴的package包/類
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; //導入方法依賴的package包/類
/**
* Path同樣也給我們封裝好了一些路徑效果，例如圓形，矩形等等，跟canvas.drawXX比較類似，這裏就簡單介紹下
*
* addArc(float left, float top, float right, float bottom, float startAngle, float sweepAngle)
* 添加弧線到路徑
*
* addCircle(float x, float y, float radius, Path.Direction dir) 添加圓到路徑
*
* addOval(float left, float top, float right, float bottom, Path.Direction dir) 添加橢圓到路徑
*
* addRect(float left, float top, float right, float bottom, Path.Direction dir) 添加矩形到路徑
*
* 上麵的Path.Direction dir參數用來指定繪製時是順時針還是逆時針，Path.Direction.CCW和Path.Direction.CW分別代表逆時針和順時針，
* 順時針和逆時針主要的作用在於不同的時針方向也就決定了不同的路徑起始點和終點，其他的參數跟canvas.drawXX是一樣的
