You can set another animation then call the animation again:

An example I did to fade text in and out:

  textAnimate: function() {
    Animated.timing(
      this.state.textOpacity,
      {
        toValue: 0.3,                         
        duration: 500, 
      }
    ).start(() => {
      Animated.timing(  
        this.state.textOpacity,            
        {
          toValue: 1,                    
          duration: 500,          
        }
      ).start(() => {
          this.textAnimate();
        });
    });    
  },

  componentDidMount: function() {
    this.state.textOpacity.setValue(1)
    this.textAnimate();
  },
