Custom Alert control in react-native

$
0
0

I am developing react-native app and trying to make a custom alert method (like Alert. alert() as given in Official site of react-native). React-native alert has no styling property for Font Size and back-ground Color, alert is very small when i'm using on android tab but it's work fine while on using in android scanner and mobile.

enter code here

import React, { Component } from 'react';
import { StyleSheet, Platform, View, Text,TouchableOpacity } from 'react-native'; 
// import PropTypes from 'prop-types';
// import Dialog from "react-native-dialog";
 import Alertfunction from './src/CustomAlert'




 export default class App extends Component{

    render() {

      return (

        <Alertfunction Title={"Alert"} FontSize = {30} FontColor= '#FF9800'  Visible={true}/>


      );
    }
  }


const styles = StyleSheet.create({

 MainContainer :{

  flex:1,
  paddingTop: (Platform.OS) === 'ios' ? 20 : 0,
  alignItems: 'center',
  justifyContent: 'center',

  }

});





customAlert.js



import React, { Component } from 'react';
import { StyleSheet, Platform, View, Text,TouchableOpacity } from 'react-native'; 
import PropTypes from 'prop-types';
import Dialog from "react-native-dialog";

class Alertfunction extends Component {
    state = {
        dialogVisible: this.props.Visible
      };

      showDialog = () => {
        this.setState({ dialogVisible: this.props.Visible });
      };

      handleCancel = () => {
         this.setState({ dialogVisible: false });
        // this.props.Visible=false;
      };

      handleDelete = () => {
         this.setState({ dialogVisible: false });
        //this.props.Visible=false;
      };

  render() {

    return (

            <View>
                <TouchableOpacity onPress={this.showDialog}>
                <Text >{this.props.Title}</Text>
                </TouchableOpacity>
                <Dialog.Container visible={this.state.dialogVisible}>
                <Dialog.Title style={{fontSize : this.props.FontSize, color: this.props.FontColor}}>{this.props.Title}</Dialog.Title>
                <Dialog.Description style={{fontSize : this.props.FontSize, color: this.props.FontColor}}>
                    Do you want to delete this account? You cannot undo this action.
                </Dialog.Description>
                <Dialog.Button style={{fontSize : this.props.FontSize, color: this.props.FontColor}} label="Cancel" onPress={this.handleCancel} />
                <Dialog.Button style={{fontSize : this.props.FontSize, color: this.props.FontColor}} label="ok" onPress={this.handleDelete} />
                </Dialog.Container>
            </View>

    );
  }
 }

export default Alertfunction;
Alertfunction.propTypes =
{
    Title: PropTypes.string,
  FontSize: PropTypes.number,
  FontColor: PropTypes.string,
  Visible: PropTypes.bool,

}

Alertfunction.defaultProps =
{
    Title: "Default Name",
  FontColor: "#00E676",
  FontSize: 15,
  Visible:false
}

const styles = StyleSheet.create({

 MainContainer :{

  flex:1,
  paddingTop: (Platform.OS) === 'ios' ? 20 : 0,
  alignItems: 'center',
  justifyContent: 'center',



  }

});
