如何在本机模式中使背景变暗? [英] How to dim a background in react native modal?

问题描述

以下是我创建的反应原生模态，但仍然找不到如何在弹出模态周围调暗背景和透明.我没有使用任何外部库并试图找到没有库的解决方案.是否可以用在这条路上?

Following is my created react native Modal and still couldn't find how to dim the background and transparent around pop-up modal.I am not using any external libraries and trying to find solution without libraries.Is it possible to do with on this way?

render() {
let modal = this.state.modalType=='skill'? <SkillModal /> : <TrialModal />;
return (
  <View style={styles.container}>
    <Modal
      animationType='slide'
      onRequestClose={() => console.log('no warning')}
      presentationStyle="FormSheet"
      transparent
      visible={this.state.showModal}
    >
      <View>
        <View style={styles.modalView} >
          <TouchableOpacity
            onPress={this.closeModalFunc}
          >
            <Text style={styles.closeText}>X</Text>
          </TouchableOpacity>
          <View>
            {modal}
          </View>
        </View>
      </View>
    </Modal>
  </View>
  );
}

模态组件样式

import {StyleSheet} from 'react-native';
import colors from '../../../theme/colors';
import metrics from '../../../theme/metrics';
import {container} from '../../../theme/base';

const styles = StyleSheet.create({
container: {
 backgroundColor: colors.background.gray,
},
modalView: {
 backgroundColor: colors.background.white,
 margin: 40,
},
closeText: {
  backgroundColor: colors.background.purpleishBlue,
  color: colors.background.white,
  borderRadius: metrics.avatar.small,
  width: 32,
  padding: 6,
  alignSelf: 'flex-end',
  textAlign: 'center',
  borderWidth: 1,
  borderColor: colors.background.white,
 },
});

export default styles;

推荐答案

我通过创建自己的组件 MyPopup 来解决这个问题，如下所示

I solve this one by create my own component MyPopup like below

class MyPopup extends React.PureComponent {

render() {
    return (
        <Modal 
            animationType="fade"
            transparent={true}
            visible={this.props.visible}
            >
                <View style={{flex: 1, alignItems: 'center', justifyContent: 'center', backgroundColor: 'rgba(0,0,0,0.5)'}}>
                    {this.props.children}
                </View>
        </Modal>
    )
}}

那我就这么用

<MyPopup visible={this.state.modalVisible}>
<View style={{
    width: '90%',
    height: 50,
    borderColor: '#ccc',
    borderWidth: 1,
    borderStyle: 'solid',
    backgroundColor: 'white',
    elevation: 20,
    padding: 10,
    borderRadius: 4,
}}>
    <Text>Hello, This is my model with dim background color</Text>
</View>
