React-native PanResponder在重新单击时重置对象的位置

Question

这些是我的依赖项：

  "dependencies": {
    "expo": "^27.0.1",
    "react": "16.3.1",
    "react-native": "~0.55.2",
    "react-native-easy-grid": "^0.2.0",
    "react-native-elements": "^1.0.0-beta5"
  }

这是我的代码：

constructor(props){
        super(props)
        this.state = {pan: new Animated.ValueXY({x:0 , y:0})}
        this._PanResponder = PanResponder.create({


            onMoveShouldSetResponderCapture: () => true,
            onMoveShouldSetPanResponderCapture: () => true,
            onStartShouldSetPanResponder: (event, gesture) => true,
            onPanResponderMove: (event, gesture) => {
                this.state.pan.setValue({x:gesture.dx , y:gesture.dy})
            },
            onPanResponderRelease: (e, {dx, dy}) => {
                console.log(dx, dy);

                this.state.pan.setValue({x:dx , y:dy})
            }
    })
}

它已连接到：

<Animated.View key={item.id} style={this.state.pan.getLayout()} {...this._PanResponder.panHandlers}>
{this.props.renderCard(item)}
</Animated.View>

当我重新单击图像时，该位置会重置到屏幕顶部（这也不是卡的默认点）。 我希望图像能够在再次被触摸后保持其位置。
