reactjs - 如何禁用子组件上的 PanResponder - React Native

Question

friend ，我将采用 parent 的一个 View ，在 View 内我采用一个 TouchableOpacity。我将在主视图上添加 panResponder，并且当触摸主视图时其工作正常。但 TouchableOpacity 不起作用，我想删除 TouchableOpacity 上的 panResponder 。这样 TouchableOpacity 就可以工作了。

代码:

    this._panResponder = PanResponder.create({
      // Ask to be the responder:
      onStartShouldSetPanResponder: (evt, gestureState) => true,
      onStartShouldSetPanResponderCapture: (evt, gestureState) => true,
      onMoveShouldSetPanResponder: (evt, gestureState) => true,
      onMoveShouldSetPanResponderCapture: (evt, gestureState) => true,


      onPanResponderGrant: (evt, gestureState) => {
        // The gesture has started. Show visual feedback so the user knows
        // what is happening!

        // gestureState.d{x,y} will be set to zero now

        // this.toggleModal()
      },
      onPanResponderMove: (evt, gestureState) => {
        // The most recent move distance is gestureState.move{X,Y}

        // The accumulated gesture distance since becoming responder is
        // gestureState.d{x,y}
        console.log('onPanResponderMove');
      },
      onPanResponderTerminationRequest: (evt, gestureState) => true,
      onPanResponderRelease: (evt, gestureState) => {
        // The user has released all touches while this view is the
        // responder. This typically means a gesture has succeeded
        console.log('onPanResponderRelease');

        this.toggleModal()
      },
      onPanResponderTerminate: (evt, gestureState) => {
        // Another component has become the responder, so this gesture
        // should be cancelled

        console.log('onPanResponderTerminate');

      },
      onShouldBlockNativeResponder: (evt, gestureState) => {
        // Returns whether this component should block native components from becoming the JS
        // responder. Returns true by default. Is currently only supported on android.

        console.log('onShouldBlockNativeResponder');

        return true;
      },
    });
 }

潘已添加到家长 View :

render() {
    return (
      <View {...this._panResponder.panHandlers}>
        <TouchableOpacity onPress={this._onPressButton}>
         <Image
          style={styles.button}
          source={require('./myButton.png')}
         />
       </TouchableOpacity>
      </View>
    );
  },

在 mainView 上添加平移时，按钮 OnPress 事件不起作用。

更改此行，然后内部 Touchables 将获取事件。

当返回 true 时，它​​将阻止子进程成为响应者。

  onStartShouldSetPanResponderCapture: (evt, gestureState) => false,

来自document :

So if a parent View wants to prevent the child from becoming responder on a touch start, it should have a onStartShouldSetResponderCapture handler which returns true.
