Android circle rotation animation and android circle Animation
The xml file for creating an animation is as follows:
Android: oneshot = "false">
Android: drawable = "@ drawable/loading_01"
Android: duration = "150">
Android: drawable = "@ drawable/loading_02"

The custom View circle moves with the finger, and the view circle
Custom View is used to implement functions that cannot be implemented by built-in controls.
To customize a View (small circle), you must first inherit a View
Public class CircleView extends View {private float cx = 100; private float cy = 100; public CircleView (Context context) {super (context);}

The main topic: Give a light source, give some circle, to find the projection interval., you can find the angle a, through the radius and the PQ distance, and angle B can also be calculated. Then we can find the angle between the two tangent lines and the y-axis, respectively, A+b,b-a. Then use the angle to find out the left and right vertices of each projection line, and sort and judge.#include POJ 1375 intervals (analytic geometry a little outside

For example, the equation of the known circle: x2+y2=32, the method of drawing a circle has the following two kinds:
Method One will evolve the circle equation to 2 functions, drawing images separately
In the first step, the circle equation is shifted and the square is opened to form two simple functions of y=√ (9-X2
