我尝试了一切.要记住的是我甚至能够使它在xcode中工作.React-native升级,npm安装和终止端口都无法正常工作.请帮忙.

当我添加固定高度样式时，它可以工作并且内容在那里，但是当我将它设置为 flex:1 （正确的方式）时，滚动视图与内容一起消失。

我的代码：

<ScrollView contentContainerStyle={{flex:1}} showsVerticalScrollIndicator={false}>
          <View style={{padding: 5}}>
            <Text>search</Text>
          </View>
          <View style={{padding: 5}}>
            <Text>New Matches</Text>
            <ScrollView contentContainerStyle={{flex:1}} horizontal={true} showsHorizontalScrollIndicator={false}>
              <View style={{padding: 10}}>
                <Thumbnail medium circle source={require('../assets/placeholders/profile1.jpg')}/>
                <Text>Christian</Text>
              </View>
              <Text>works</Text>
              <Text>works</Text>
              <Text>works</Text>
              <Text>works</Text>
              <Text>works</Text>
            </ScrollView> 

另外，如您所见，我有两个滚动视图。我指的是最外面的（垂直滚动视图）。

现在我正在将一个带有端点的数组映射到我的 API。从那里，我将获取每个链接并在我映射的每个事物上调用 get 请求。我的问题是我无法将所有内容保存到我的 redux 状态。我曾尝试使用 concat 和 push 来获取所有内容，并将其全部放入我的 redux 状态中的一个数组中。

MomentContent.js：

componentDidMount () {

      this.props.photos.map(photo => {
        this.props.fetchPhoto(this.props.token, photo)}
      )
    }

index.js（动作）：

export const fetchPhoto = (token, photo) => dispatch => {
  console.log('right token')
  console.log(token);
  fetch(photo, {
    method: 'GET',
    headers: {
      'Accept': 'application/json',
      'Content-Type': 'application/json',
      'Authorization': `Token ${token}`,
    }
  })
  .then(res => res.json())
  .then(parsedRes => {
    console.log('photo data')
    console.log(parsedRes)
    dispatch(getPhoto(parsedRes))
  })
}

export const getPhoto = (photo) => {
  console.log('RES')
  console.log(photo)
  return {
    type: GET_PHOTO,
    photo: photo
  } …

我得到的更具体的错误是：警告：道具类型失败：道具store在中标记为必需Provider，但其值为undefined。

store.js

const initialState = {};

const storage = createSensitiveStorage({
  keychainService: "myKeychain",
  sharedPreferencesName: "mySharedPrefs"
});

const config = {
  key: "root",
  storage,
};

const middleware = [thunk];

const reducer = persistCombineReducers(config, rootReducer);

export default () => {
  let store = createStore(
    reducer,
    initialState,
    compose(applyMiddleware(...middleware))
  );
  let persistor = persistStore(store);

  return { store, persistor }
}

用于减速器的index.js：

export default combineReducers({
    profile: profileReducer,
    auth: authReducer,
    photoSlider,
    trip: tripReducer,
    moment: momentReducer
})

App.js：

import {store, persistor} from …

所以我目前可以在框外单击时关闭模态，但问题是当我在框内单击时它仍然关闭。我试过添加pointerEvents="none"，这似乎不起作用。

这是我的代码：

<View>
          <Modal
            animationType="slide"
            transparent={true}
            style={{width: '100%', alignSelf: 'center', height: '100%', justifyContent: 'flex-start', backgroundColor:'green'}}
            visible={this.state.modalVisible}
            onRequestClose={() => {
              alert('Modal has been closed.');
            }}>
            <TouchableWithoutFeedback onPress={() => {
              this.setModalVisible(!this.state.modalVisible);
            }}>
            <View style={{ backgroundColor: 'red', flex: 1}} >

                <View pointerEvents="none" style={{alignSelf: 'center', width: '80%', height: '50%', backgroundColor: 'purple', top: 100}}>
                  <Text pointerEvents="none" >Hello World!</Text>


                </View>

            </View>
            </TouchableWithoutFeedback>
          </Modal>
        </View>
