PanResponder React本机

Question

我在React-native中遇到PanResponder的问题。 我不明白如何使用它...我的代码：

export default class Index_preferences extends Component {
componentWillMount() {
    this._panResponder = PanResponder.create({
      onPanResponderMove: this._handlePanResponderMove,
      onPanResponderGrant: this._handlePanResponderGrant,
    });
  }

_handlePanResponderMove(event, gestureState) {
    console.log(gestureState);
  }

  _handlePanResponderGrant(event, gestureState) {
    console.log(gestureState);
  }

componentTag() {
   return tabTag.map((item, id) => {
      return(
        <View key={id} {...this._panResponder.panHandlers}>
          <Text>Here</Text>
        </View>
      );
    });
}

render() {
  return (
    <View> {this.componentTag()} </View>
  );
}

}

但是没有任何反应我的控制台什么也没显示

谢谢 ！

对不起，这个帖子解决方法：添加：

onStartShouldSetPanResponder: (evt, gestureState) => true,
onStartShouldSetPanResponderCapture: (evt, gestureState) => true,
onMoveShouldSetPanResponder: (evt, gestureState) => true,
onMoveShouldSetPanResponderCapture: (evt, gestureState) => true,

在

this._panResponder = PanResponder.create({
      onPanResponderMove: this._handlePanResponderMove,
      onPanResponderGrant: this._handlePanResponderGrant,
    });
