我想在androidstudio中的XML文件中显示原生广告视图,但它给了我一个错误

我想在androidstudio中的XML文件中显示原生广告视图,但它给了我一个错误,android,Android,基本上,我的问题是,当我在XML文件中添加本机的ads_视图时,它会给我错误(“缺少必需的XML_属性“adSize”) XML文件: <?xml version="1.0" encoding="utf-8"?> <androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http:

我找到了一个解决方案,如果您这样使用它,它将起作用:

<com.google.android.gms.ads.NativeExpressAdView
 android:id="@+id/adView"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 ads:adSize="FULL_WIDTHx80"
 ads:adUnitId="@string/native_ad_unit"/>

或者可以通过使缓存无效并重新启动android studio来解决,或者尝试将大小更改为ads:adSize=“300x250”肯定能用。

试着在java端设置广告大小。我该怎么做?请你给我发一段代码作为例子。我知道这是一个奇怪的解决方案,但你能尝试在android studio中使缓存无效并重新启动吗?或者在java中设置它,你可以做最后的AdView AdView=new AdView(getActivity());adView.setAdUnitId(“YourId”);adView.setAdSize(AdSize.BANNER);(在这里发布问题时,请保持你的帖子清晰简洁。问候语、你有多困、你搜索了多少、你正在等待答案等都是无关紧要的,最好不要添加。它们只会让你的帖子变得杂乱无章,不易阅读)在应用我的建议@Shanimalik时,你是否也遇到了同样的错误谢谢你,先生,现在一切正常……我使用这一步骤使缓存失效,并重新启动android,错误得到了解决
<com.google.android.gms.ads.NativeExpressAdView
 android:id="@+id/adView"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 ads:adSize="FULL_WIDTHx80"
 ads:adUnitId="@string/native_ad_unit"/>
nativeAd = new NativeExpressAdView(this);
int widthInDP = context.getResources().getConfiguration().screenWidthDp;
    widthInDP -= context.getResources().getDimension(R.dimen.activity_horizontal_margin);
nativeAd.setAdSize(new AdSize(widthInDP, 250)); 
nativeAd.setAdUnitId("myAdUnitId");

// Create an ad request.
AdRequest.Builder adRequestBuilder = new AdRequest.Builder();

// Optionally populate the ad request builder.
adRequestBuilder.addTestDevice(AdRequest.DEVICE_ID_EMULATOR);

// Add the NativeExpressAdView to the view hierarchy.
layout.addView(nativeAd);

// Start loading the ad.
nativeAd.loadAd(adRequestBuilder.build());
