朋友，我将采用一个父母视图，在视图内我采用一个 TouchableOpacity。我将在主视图上添加 panResponder，当触摸主视图时它工作正常。但是 TouchableOpacity 不起作用，我想删除 TouchableOpacity 上的 panResponder。所以 TouchableOpacity 是有效的。

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;
      },
    });
 }

潘在家长视图中添加： 

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 Pan 时，Button OnPress 事件不起作用。

更改此行，然后内部Touchables将获取事件。

返回 true 时，它​​将阻止孩子成为响应者。

  onStartShouldSetPanResponderCapture: (evt, gestureState) => false,

从文件：

因此，如果父 View 想要阻止子 View 在触摸开始时成为响应者，它应该有一个 onStartShouldSetResponderCapture 处理程序，该处理程序返回 true。
