我有这个安卓网络视图应用。我提出了一些函数。然后,它停止显示广告。广告是间隙广告。
我做了一些改变。然后,它显示广告,但没有返回功能。。。
import React, { Component } from 'react';
import { BackHandler} from 'react-native';
import { WebView } from 'react-native-webview';
import { AdMobInterstitial, AdMobBanner } from 'expo-ads-admob';
// ...
class MyWebComponent extends Component {
webView = {
canGoBack: false,
ref: null,
}
onAndroidBackPress = () => {
if (this.webView.canGoBack && this.webView.ref) {
this.webView.ref.goBack();
return true;
}
return false;
}
componentDidMount() {
if (Platform.OS === 'android') {
BackHandler.addEventListener('hardwareBackPress', this.onAndroidBackPress);
}
}
componentWillUnmount() {
if (Platform.OS === 'android') {
BackHandler.removeEventListener('hardwareBackPress');
}
}
}
export default class App extends React.Component {
adFunction = async () => {
AdMobInterstitial.setAdUnitID('ca-app-pub-');
await AdMobInterstitial.requestAdAsync({ servePersonalizedAds: true});
await AdMobInterstitial.showAdAsync();
}
componentDidMount() {
this.adFunction();
}
render() {
return (
<WebView
source={{ uri: "https://.com" }}
ref={(webView) => { this.webView.ref = webView; }}
onNavigationStateChange={(navState) => { this.webView.canGoBack = navState.canGoBack; }}
/>
);
}
}
export default MyWebComponent
谁能帮我一下吗?谢谢
