如何使这个自定义按钮组件可跨不同控件重用？

Question

我将这个自定义组件 class 应用于我的 React Native 按钮，它具有按比例放大和缩小（添加动画以缩小和调整大小）的预期行为，这是我想要的行为。但是，我希望我的应用程序中的其他控件（例如 Cards）具有相同的动画。我想知道，如何更改此 class 以使其更具可扩展性？

这是我的代码：

import React from "react";
import { StyleSheet, Text, TouchableWithoutFeedback, Animated} from "react-native";
import Colors from "./Colors";
import Fonts from "./Fonts";

export default class TouchableBounce extends React.Component {

  constructor(props) {
    super(props);

    this.handlePressIn = this.handlePressIn.bind(this);
    this.handlePressOut = this.handlePressOut.bind(this);

  }

  componentWillMount() {
    this.animatedValue = new Animated.Value(1);
  }

  handlePressIn() {
    Animated.spring(this.animatedValue, {
      toValue: .5
    }).start()
  }

  handlePressOut() {
    Animated.spring(this.animatedValue, {
      toValue: 1,
      friction: 5,
      tension: 40
    }).start()
  }

  render() {

    const animatedStyle = {
        transform: [{ scale: this.animatedValue}]
      }

    const {
        disabled,
        text,
        color,
        backgroundColor,
        style,
        showArrow,
        testID,
        buttonStyle

    } = this.props;

    return (
      <TouchableWithoutFeedback
        onPressIn={this.handlePressIn}
        onPressOut={this.handlePressOut}
        disabled={disabled}
        style={[styles.buttonContainer, style]}
        testID={testID || `button_${text}`}
      >
        <Animated.View
          style={[
            styles.button,
            disabled ? { opacity: 0.5 } : {},
            { backgroundColor },
            buttonStyle,
            animatedStyle
          ]}
        >
          <Text style={[styles.buttonText, { color }]}>{text.toUpperCase()}</Text>
          {showArrow && (
            <Text
              style={{
                fontSize: 20,
                fontWeight: "bold",
                color: "white",
                fontFamily: "system font",
                marginBottom: 1
              }}
            >
              {" "}
              →
            </Text>
          )}
        </Animated.View>
      </TouchableWithoutFeedback>
    );
  }
} 

TouchableBounce.defaultProps = {
  disabled : false,
  color : Colors.white,
  backgroundColor : Colors.mainAccent,
  style : {},
  showArrow : false,
  testID : "",
  buttonStyle : {}
}

const styles = StyleSheet.create({
  buttonContainer: {
    alignSelf: "stretch",
    marginTop: 35,
    marginBottom: 35
  },
  button: {
    borderRadius: 4,
    padding: 20,
    flexDirection: "row",
    alignItems: "center",
    justifyContent: "center"
  },
  buttonText: {
    textAlign: "center",
    fontFamily: Fonts.montserratBold,
    fontSize: 16
  }
});

编辑：我有一个问题，我应该在哪里进行更改以嵌套 component.Inside 我的主页渲染功能有这个片段

const card = active ? (
      <ActiveCard purchase={active} />

    ) : (
      <InactiveCard />
    );

在我的 return 渲染中，有这个片段

{!this.props.foo && (
                <View>
                  <TouchableOpacity
                    testID={"TOUCHABLE_CARD"}
                    onPress={() => {
                      this.tapCard(active);
                    }}
                  >
                    {card}
                  </TouchableOpacity>
                </View>
              )}

我应该在哪里包装 TouchableBounce？在两个地方还是其中一个地方？

Answer 1

尝试将它们作为 TouchableBounce

的子代传递

<TouchableBounce>
  <CardView/>
</TouchableBounce>

在 TouchableBounce 中将它们渲染为

<TouchableWithoutFeedback
  onPressIn={this.handlePressIn}
  onPressOut={this.handlePressOut}
  disabled={disabled}
  style={[styles.buttonContainer, style]}
  testID={testID || `button_${text}`}
>
  <Animated.View
    style={[
      styles.button,
      disabled ? { opacity: 0.5 } : {},
      { backgroundColor },
      buttonStyle,
      animatedStyle
    ]}
  >
    {this.props.children}//Here is the cardview that you have sent
  </Animated.View>
</TouchableWithoutFeedback>

为了清楚理解，我附上了一个工作演示 Expo demo

还有官方文档React.Children
