使用<View style={{ flex: 1, flexDirection: "column", flexWrap: "wrap", borderTopWidth: 5, borderBottomWidth: 5, backgroundColor: "#F8F9F9" }} > <Logo /> <Text style={styles.titleText1}> Daily Attendance Section A Class 11th </Text> <ActivityIndicator animating={animating} color="#bc2b78" size="large" style={styles.activityIndicator} /> <View style={styles.container}> <Text style={styles.titleText}>Roll & Name Present Or Absent</Text> </View> <FlatList data={this.state.data} showsVerticalScrollIndicator={false} renderItem={({ item }) => ( <View style={{ flex: 1, flexDirection: "row", height: 50, backgroundColor: "#D1F2EB", borderRadius: 4, borderWidth: 1, borderColor: "#008000", marginLeft: "1%" }} > <Text style={{ flex: 2, fontSize: 15, // fontFamily: "Roboto", // justifyContent: "space-between", width: 150 }} > {item.rollno} -- {item.name} {/* onChangeText={(rollno) => this.setState({rollno: rollno})} */} {/* this.setState({ item.rollno }); */} </Text> <RadioForm animation={true} buttonColor={"#C2E3A9"} formHorizontal={true} labelHorizontal={true} buttonStyle={{ marginRight: 20 }} radioStyle={{ paddingRight: 20 }} // labelHorizontal={false} style={{ flex: 1, paddingRight: 20, flexDirection: "row", //padding: 10, width: 30 }} radio_props={radio_props} initial={this.state.value} onPress={value => { this.setState({ value: value }); }} ItemSeparatorComponent={this.renderSeparator} /> data1={[{"rollno": item.rollno}, {"typeofattendence": this.state.value}]} <Button title="Submit" onPress={() => this.insert(item)} /> </View> )} // keyExtractor={(x, i) => i} keyExtractor={(item, index) => index.toString()} /> <Button title="Submit" onPress={() => this.insert()} /> </View>` and here I json stringfy code for posting `insert = (item) => { /* */ //alert(this.state.username); fetch("http://192.168.1.139:8082/Attendence/add", { method: "POST", headers: { Accept: "application/json", "Content-Type": "application/json" }, body: JSON.stringify([{ rollno: item.rollno, typeofattendence: this.state.value }]) }) .then(response => response.json()) .then(res => { if (res.success === true) { alert(res.message); } else { alert(res.message); } }) .catch(error => { console.error(error); }); }; 方法可能会导致主题更改！
