        <View style={styles.inputView}>
            <TextInput style={styles.input}/>

    var styles = StyleSheet.create ({

            backgroundColor: '#F5FCFF',
        },
        map: {
            flex: 1,
        },
        inputView: {
            backgroundColor: 'rgba(0,0,0,0)',
            position: 'absolute', 
            top: 0,
            left: 5,
            right: 5
        },
        input: {
            height: 36,
            padding: 10,
            marginTop: 20,
            marginLeft: 10,
            marginRight: 10,
            fontSize: 18,
            borderWidth: 1,
            borderRadius: 10,
            borderColor: '#48BBEC',
            backgroundColor: 'white',
        }
    })

尝试将文本输入包装在另一个视图中，并将该视图的背景设置为透明：

<View style={styles.container}>
    <MapView style={styles.map}/>
    <View style={styles.inputWrapper}>
       <TextInput style={styles.inputSearch}/>
    </View>
</View>

inputWrapper: {
    flex: 1,
    backgroundColor: 'transparent',
    position: 'absolute', 
    top: 0,
  },
inputSearch: {
    backgroundColor: 'rgba(0,0,0,0.4)', // 40% opaque
    color: 'white',
}
