ListHeaderComponent里面flatlist不工作。它不会在标题中呈现任何内容（上图flatlist）。但是，如果我放置一些自定义组件，它确实可以工作，但它不适用于我的renderHeader功能。我尝试使用与中相同的视图制作自定义组件，renderHeader但是当我使用它时没有渲染所以我不知道
我的平面列表以及整个渲染：
render() {
const { height } = Dimensions.get("window");
return (
<View style={{flex: 1,
backgroundColor: "#EBECF4"}}>
{/* <Text>
Connection Status :{" "}
{this.state.connection_status ? "Connected" : "Disconnected"}
</Text> */}
{/* <Loader loading={this.state.loading} /> */}
<StatusBar backgroundColor="#63003d" barStyle="light-content" />
<SafeAreaView>
<ModernHeader
backgroundColor="#63003d"
height={50}
text="Eleph"
textStyle={{
color: "white",
fontFamily: "Lobster-Regular",
//fontWeight: "bold",
fontSize: 25,
}}
leftIconComponent={
<TouchableOpacity
style={{ marginRight: 0, margin: 0 }}
onPress={() =>
this.props.navigation.dispatch(DrawerActions.openDrawer())
}
>
<FontAwesome5 name="bars" size={22} color="white" />
</TouchableOpacity>
}
rightIconComponent={
<TouchableOpacity
style={{ marginLeft: 0, margin: 0 }}
onPress={() => this.props.navigation.navigate("Profile")}
>
{/* <MaterialCommunityIcons
name="chart-areaspline"
size={24}
color="#639dff"
/> */}
<Foundation name="graph-bar" size={24} color="white" />
{/* <FontAwesome name="bar-chart" size={24} color="white" /> */}
</TouchableOpacity>
}
/>
</SafeAreaView>
<FlatList
//contentInset={{ top: HEADER_HEIGHT }}
//contentOffset={{ y: -HEADER_HEIGHT }}
data={this.state.post}
extraData={this.state.post}
keyExtractor={(item) => item.id.toString()}
style={{
marginHorizontal: 0,
marginVertical: 6,
}}
renderItem={({ item }) => this.renderPost(item)}
ListFooterComponent={this.renderFooter}
ListHeaderComponent={this.renderHeader}
refreshControl={
<RefreshControl
style={{ color: "#639dff" }}
tintColor="#639dff"
titleColor="#fff"
refreshing={this.state.isLoading}
onRefresh={this.onRefresh}
/>
}
initialNumToRender={7}
onEndReachedThreshold={0.1}
showsVerticalScrollIndicator={false}
onEndReached={() => {
if (
!this.onEndReachedCalledDuringMomentum &&
!this.state.isMoreLoading
) {
this.getMore();
}
}}
onMomentumScrollBegin={() => {
this.onEndReachedCalledDuringMomentum = false;
}}
onScroll={(e) => {
scrollY.setValue(e.nativeEvent.contentOffset.y);
}}
></FlatList>
{/* <View style={styles.footer}>
<TouchableOpacity
activeOpacity={0.9}
onPress={this.getMore}
style={styles.loadMoreBtn}
>
<Text style={styles.btnText}>See more moods</Text>
{this.state.loading ? (
<ActivityIndicator color="white" style={{ marginLeft:8 }} />
) : null}
</TouchableOpacity>
</View> */}
</SafeAreaView>
</View>
我的 renderHeader 函数：
renderHeader = () => {
return (
<View
style={{
flex: 1,
flexDirection: "row",
backgroundColor: "#ffffff",
//width: "100%",
padding: 11,
alignItems: "center",
position: "absolute",
justifyContent: "center",
//top: 50,
//bottom: 0,
//left: 0,
//elevation: 4,
//right: 0,
//height: 50,
}}
//flexDirection: "row",
//backgroundColor: "#ffffff",
//width: "100%",
//padding: 11,
//alignItems: "center",
>
<TouchableOpacity
onPress={() => this.props.navigation.navigate("Post")}
>
<Text
style={{ alignItems: "center", color: "#C4C6CE" }}
//placeholder={How are you feeling right now ${this.state.user.name}?}
multiline
>{Tell us how are you feeling right now ${this.state.user.name}?}</Text>
</TouchableOpacity>
{/* <View style={styles.divider}></View> */}
</View>
);
}
为什么例如 renderFooter 作品？
renderFooter = () => {
if (!this.state.isMoreLoading) return true;
return (
<ActivityIndicator
size="large"
color={"#D83E64"}
style={{ marginBottom: 10 }}
/>
);
};
