[英]How to expand search bar after presses on search icon
我通過某種方式創建了一個搜索圖標,我只是想知道當有人按下搜索欄圖標時如何展開它。
import { TouchableOpacity,View, Image} from 'react-native';
import { SearchBar } from 'react-native-elements';
export default class Search extends Component{
onClick(){
return <SearchBar/> // [![Seach Image][1]][1]not working
}
render(){
// not worrking
let search = <SearchBar/>;
return(
<View>
<TouchableOpacity
onPress={() => {
return search
}}
>
<Image
source={require('../images/tabs/search.png')}
style={{height: 40, width: 60}}
resizeMode={'contain'}
/>
</TouchableOpacity>
</View>
)
}
}
您應該在組件中添加狀態以控制標題的行為
import { TouchableOpacity, View, Image } from 'react-native';
import { SearchBar } from 'react-native-elements';
export default class Search extends Component {
constructor(props) {
super(props);
this.onClick = this.onClick.bind(this);
this.state = {
showSearchBar: false, // control what ever to render the searchbar or just the icon
};
}
onClick() {
let { showSearchBar } = this.state;
this.setState({
showSearchBar: !showSearchBar,
});
}
render() {
const { showSearchBar } = this.state;
return (
<View>
{!showSearchBar ? (
<TouchableOpacity onPress={this.onClick}>
<Image
source={require('../images/tabs/search.png')}
style={{ height: 40, width: 60 }}
resizeMode={'contain'}
/>
</TouchableOpacity>
) : (
<SearchBar />
)}
</View>
);
}
}
