问在react native中，有没有办法判断用户是否一直在触摸屏幕？

this._panResponder = PanResponder.create({
            onMoveShouldSetResponderCapture: () => true,
            onMoveShouldSetPanResponderCapture: () => true,

            // Initially, set the Y position offset when touch start
            onPanResponderGrant: (e, gestureState) => {
                this.setState({
                    offset: e.nativeEvent.pageY,
                    isDividerClicked: true
                })
            },

            // When we drag the divider, set the bottomHeight (component state) again.
            onPanResponderMove: (e, gestureState) => {

                this.setState({
                    bottomHeight    : gestureState.moveY > (this.state.deviceHeight - 40) ? 40 : this.state.deviceHeight - gestureState.moveY,
                    offset: e.nativeEvent.pageY
                })
            },

            onPanResponderRelease: (e, gestureState) => {
                // Do something here for the touch end event
                this.setState({
                    offset: e.nativeEvent.pageY,
                    isDividerClicked: false
                })
            }
        });
