[英]How to Draw a Bitmap image in a arc shape in android to create a spin
[英]How to find Center of Gravity of the shape in the Image (Bitmap)
这是我的工作,我试图使用选定的图像坐标在图像(位图)中找到形状的重心:
float xpos = 0f , ypos = 0f;
PointF currF = new PointF();
for (PointF pointF : pointFArrayList){
xpos += pointF.x;
pos += pointF.y;
}
currF.x = xpos/pointFArrayList.size();
currF.y = ypos/pointFArrayList.size();
addRoundIconToViewRed(currF); //Marking the center of gravity
例如,请参阅此图像:
1.首先将位图设置为图像视图
2.获取该特定图像视图的中心点
centreX=imageView.getX() + imageView.getWidth() / 2;
centreY=imageView.getY() + imageView.getHeight() / 2;
