Question

function submit(email, password) { 
  FirebaseAPI.createUser(email, password)
}

export default function LoginScreen() {
  
  const [email, onChangeText] = React.useState('Enter Email');
  const [password, onChangeText2] = React.useState('Enter Password');

  const componentDidMount = () => {
    this.watchAuthState(this.props.navigation)
  }
  const watchAuthState =(navigation) => {
    firebase.auth().onAuthStateChanged(function(user) {
      console.log('onauthStateChanged', user)
      if (user) {
        this.props.navigation.navigate('Main');
        // this.props.navigation.navigate('App');
      }
    });
  }
  return (
    <KeyboardAvoidingView style={styles.wrapper} behavior="padding">
          <View style={styles.scrollViewWrapper}>
            <ScrollView style={styles.scrollView}>
              <Text style={styles.loginHeader}>Creat an Account </Text>
              <TextInput 
                style={{ height: 40, borderColor: 'gray', borderWidth: 1 }}
                onChangeText={text => onChangeText(text)}
                value={email}
              />
              <TextInput 
                style={{ height: 40, borderColor: 'gray', borderWidth: 1 }}
                onChangeText={text => onChangeText2(text)}
                value={password}
              />
              <TouchableOpacity
                style={{marginTop: '5%'}}
                onPress= {(submit(email,password))}>
                <View>
                    <Text>Submit</Text>
                </View>
              </TouchableOpacity> 
            </ScrollView>
           </View>
         </KeyboardAvoidingView>
  );
}

Firebase可以正常使用此功能，但是我有一个问题，即使我输入说john@gmail.com密码sfjkskfs等，即使在我按下“提交”按钮之前，它也会自动将其发送到Firebase。

任何帮助都会很棒！

我认为您在onPress函数中使用了错误的代码。您应该对此部分使用onPress函数

onPress = {() => this.submit(email,password)}

反应本机功能自动提交到firebase？
