二、知识基础：闪烁动画工具的核心原理与实现逻辑

在展示完整代码之前，我们需要深入理解闪烁动画工具的核心原理和实现逻辑。掌握这些基础知识后，你将能够举一反三应对各种闪烁动画相关的开发需求。

1. 闪烁动画的基本原理

闪烁动画通过透明度的周期性变化，创造出忽明忽暗的视觉效果：

// 闪烁动画核心原理
// 1. 使用 Animated.loop 实现循环闪烁
// 2. 通过 opacity 控制透明度
// 3. 使用不同的时长创造不同的闪烁节奏
// 4. 适用于加载、提示、警告等场景

// 基础闪烁实现
const BlinkBase = () => {
  const opacityAnim = useRef(new Animated.Value(1)).current;

  useEffect(() => {
    Animated.loop(
      Animated.sequence([
        Animated.timing(opacityAnim, {
          toValue: 0.3,
          duration: 500,
          useNativeDriver: true,
        }),
        Animated.timing(opacityAnim, {
          toValue: 1,
          duration: 500,
          useNativeDriver: true,
        }),
      ])
    ).start();
  }, []);

  return (
    <Animated.View
      style={{
        opacity: opacityAnim,
      }}
    >
      <Text>闪烁动画</Text>
    </Animated.View>
  );
};

核心要点：

• 使用 loop 实现循环
• 通过 opacity 控制透明度
• 创造忽明忽暗效果
• 适用于提示场景

2. 快速闪烁效果

实现快速的闪烁效果：

const FastBlink = () => {
  const opacityAnim = useRef(new Animated.Value(1)).current;

  useEffect(() => {
    Animated.loop(
      Animated.sequence([
        Animated.timing(opacityAnim, {
          toValue: 0.2,
          duration: 200,
          useNativeDriver: true,
        }),
        Animated.timing(opacityAnim, {
          toValue: 1,
          duration: 200,
          useNativeDriver: true,
        }),
      ])
    ).start();
  }, []);

  return (
    <Animated.View
      style={{
        opacity: opacityAnim,
      }}
    >
      <Text>快速闪烁</Text>
    </Animated.View>
  );
};

核心要点：

• 使用较短的动画时长
• 创造快速闪烁
• 适用于紧急提示
• 视觉效果强烈

3. 慢速闪烁效果

实现缓慢的闪烁效果：

const SlowBlink = () => {
  const opacityAnim = useRef(new Animated.Value(1)).current;

  useEffect(() => {
    Animated.loop(
      Animated.sequence([
        Animated.timing(opacityAnim, {
          toValue: 0.5,
          duration: 1000,
          useNativeDriver: true,
        }),
        Animated.timing(opacityAnim, {
          toValue: 1,
          duration: 1000,
          useNativeDriver: true,
        }),
      ])
    ).start();
  }, []);

  return (
    <Animated.View
      style={{
        opacity: opacityAnim,
      }}
    >
      <Text>缓慢闪烁</Text>
    </Animated.View>
  );
};

核心要点：

• 使用较长的动画时长
• 创造缓慢闪烁
• 适用于柔和提示
• 视觉效果温和

4. 闪烁停止效果

实现闪烁后停止的效果：

const BlinkStop = () => {
  const [isBlinking, setIsBlinking] = useState(false);
  const opacityAnim = useRef(new Animated.Value(1)).current;
  const animationRef = useRef<Animated.CompositeAnimation | null>(null);

  useEffect(() => {
    if (isBlinking) {
      animationRef.current = Animated.loop(
        Animated.sequence([
          Animated.timing(opacityAnim, {
            toValue: 0.3,
            duration: 500,
            useNativeDriver: true,
          }),
          Animated.timing(opacityAnim, {
            toValue: 1,
            duration: 500,
            useNativeDriver: true,
          }),
        ])
      );
      animationRef.current.start();
    } else {
      if (animationRef.current) {
        animationRef.current.stop();
        animationRef.current = null;
      }
      Animated.timing(opacityAnim, {
        toValue: 1,
        duration: 300,
        useNativeDriver: true,
      }).start();
    }

    return () => {
      if (animationRef.current) {
        animationRef.current.stop();
      }
    };
  }, [isBlinking]);

  return (
    <View>
      <TouchableOpacity onPress={() => setIsBlinking(!isBlinking)}>
        <Text>{isBlinking ? '停止' : '开始'}闪烁</Text>
      </TouchableOpacity>
      <Animated.View
        style={{
          opacity: opacityAnim,
        }}
      >
        <Text>闪烁</Text>
      </Animated.View>
    </View>
  );
};

核心要点：

• 支持开始和停止
• 停止时恢复不透明
• 清理动画避免泄漏
• 适用于交互提示

5. 闪烁进入效果

实现元素闪烁进入的效果：

const BlinkEnter = () => {
  const [visible, setVisible] = useState(false);
  const opacityAnim = useRef(new Animated.Value(0)).current;

  useEffect(() => {
    if (visible) {
      Animated.sequence([
        Animated.timing(opacityAnim, {
          toValue: 0.3,
          duration: 300,
          useNativeDriver: true,
        }),
        Animated.timing(opacityAnim, {
          toValue: 1,
          duration: 300,
          useNativeDriver: true,
        }),
        Animated.timing(opacityAnim, {
          toValue: 0.5,
          duration: 300,
          useNativeDriver: true,
        }),
        Animated.timing(opacityAnim, {
          toValue: 1,
          duration: 300,
          useNativeDriver: true,
        }),
      ]).start();
    }
  }, [visible]);

  return (
    <View>
      <TouchableOpacity onPress={() => setVisible(true)}>
        <Text>显示</Text>
      </TouchableOpacity>
      {visible && (
        <Animated.View
          style={{
            opacity: opacityAnim,
          }}
        >
          <Text>闪烁进入</Text>
        </Animated.View>
      )}
    </View>
  );
};

核心要点：

• 显示时闪烁几次
• 使用 sequence 组合动画
• 适用于弹窗显示
• 视觉效果吸引
