Answer 1

你可以设置backgroundColor：'rgba（0,0,0,0.2）'。

<Modal
      animationType={"slide"}
      transparent={false}
      visible={this.state.modalVisible}
      onRequestClose={() => {alert("Modal has been closed.")}}

      >

     <View style={{flex: 1,backgroundColor: 'rgba(0,0,0,0.2)'}}>
      <View style ={{flex:1, alignItems: 'center', justifyContent: 'center'}}>
          <View style={{backgroundColor: '#ffffff', width: 300, height: 300}}>
              <Text>Hello World!</Text>
          </View>
        <TouchableHighlight
          style={{backgroundColor: '#ffffff', width: 300, height: 40, marginTop: 40}}
          onPress={() => {this.setModalVisible(!this.state.modalVisible)}}
        >
          <Text>Hide Modal</Text>
        </TouchableHighlight>

      </View>
     </View>
    </Modal>

对于iOS而言，有一个名为ActionSheetIOS的组件，您可以这样调用它：

ActionSheetIOS.showActionSheetWithOptions(
  {
    options: ["Cancel", ...options],
    title: "Select something",
    message: "Some description",
    cancelButtonIndex: 0 
  },
  index => {
    // do something with the selected index
    const listIndex = index - 1;
    if (index > 0) {
      this.setState({ selectedIndex: listIndex });
    }
  }
);

仅在iOS中

  import { StyleSheet, Text, ActionSheetIOS } from "react-native"; 

  ...
  OptionButton() {
    let BUTTONS = ["Compartir", "Reportar", "Cancel"];
    ActionSheetIOS.showActionSheetWithOptions(
      {
        title: "Opciones",
        tintColor: "#242424",
        options: BUTTONS,
        cancelButtonIndex: 2,
        destructiveButtonIndex: 1
      },
      buttonIndex => {
        switch (buttonIndex) {
          case 0:
            this.shareImage();
            break;
          case 1:
            this.reportImage();
            break;
        }
      }
    );
  }
