How to use View Animation

Question

I’d like to know how you would use View Animation ,to simulate a GIF.

For example: I have a picture of a sword, this sword is up, so do something like it goes right, clockwise,going around and going back to its original position.

Someone has worked this way before?

Android provides various types of animations that can apply to a Imageview. The one that applies in your case is Rotateanimation.

Its use is done in 3 steps:

1 - Create an object of type Rotateanimation

//Cria uma animação de rotação desde de 0º a 360º com o eixo de rotação no centro da imagem.
RotateAnimation animation = new RotateAnimation(0f, 360f,
                                                Animation.RELATIVE_TO_SELF, 0.5f, 
                                                Animation.RELATIVE_TO_SELF, 0.5f);

2 - Define animation properties.

// 3 segundos.
long tempo = 3000;

//Define que a animação se processa de forma linear
animation.setInterpolator(new LinearInterpolator());

//Define o tempo da animação 
animation.setDuration(tempo);

3 - Start it.

imageView.startAnimation(animation);
