在低于3.0的Android中如何使用rotateY属性？

Question

I want to use rotateY=180 attribute in Android older than 3.0. How should I override onDraw method in my custom view to create this behavior of attributes? In the Android greater than 3.0 there is no problem with it but in older one this is not supported.

Answer 1

You can use this

public void draw(Canvas canvas) 
{
canvas.save();
canvas.rotate(angle * 180.0f / (float) Math.PI);



canvas.restore();
}
