我想在應用程序中包含admob橫幅，並且出現了這個奇怪的錯誤。任何幫助深表謝意。AdView未能實例化
下面是XML代碼
<com.google.ads.AdView android:id="@+id/adView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="bottom"
ads:adUnitId="..."
ads:adSize="BANNER"
/>
在活動中，我寫了下面的代碼
adview = (AdView)findViewById(R.id.adView);
adview.setVisibility(View.VISIBLE);
AdRequest re = new AdRequest();
adview.loadAd(re);
在logcat中我碰到下面的錯誤
Not enough space to show ad! Wants: <480, 75>, Has: <0, 800>
我懷疑必須有一個額外的問題，因爲我將AdView的寬度設置爲「wrap_content」
在XML文件中的圖形視圖有此警告
，當我點擊這個錯誤我看到有一個java.lang.UnsupportedOperationException
如果你想以進一步調查此處是完整異常堆棧跟蹤

問題將在運行時間之前。我的意思是你的圖形視圖的佈局需要工作。它應該顯示「com.google ... AdView」，如果它工作正常。我不能說出其他佈局有什麼問題。如果你把整件事放在這裏，有人 - 也許是我 - 可以看看。 – DrA
您的佈局高度和寬度可能會阻止它正確顯示 – xDragonZ
您確定@xDragonZ，因爲我將寬度和高度設置爲wrap_content。你怎麼看待相關的UnsupportedOperationException？我想這個例外可以防止廣告被顯示，這就是爲什麼我得到「空間不夠」的錯誤。 AdView不包含任何廣告，因此wrap_content屬性的寬度爲0。 – 0x5f3759df
