参考WeItemDetail.js

参考SelfImageModalPage.js

首先import {Platform,Keyboard} from 'react-native';

设置键盘高度62行

然后设置键盘隐藏和显示

componentDidMount(){

Keyboard.addListener('keyboardWillShow', this.keyboardWillShow.bind(this))

Keyboard.addListener('keyboardWillHide', this.keyboardWillHide.bind(this))

}

_setModalVisible(visible) {

this.setState({modalVisible: visible});

};

keyboardWillShow (e) {

this.setState({keybordHeight:e.endCoordinates.height})

}

keyboardWillHide (e) {

this.setState({keybordHeight:0})

}

最后把样式添加
