廣告不顯示，在CardView邊緣有FULL_WIDTH問題。有沒有辦法做到這一點？在CardView上顯示使用FULL_WIDTH和一些邊距的添加。我也嘗試在父視圖上使用填充和邊距，而不是在CardView上使用邊距來解決同樣的問題。

Answer 1

FULL_WIDTH常量指定廣告應占據設備屏幕的整個寬度。在你的情況下，廣告沒有足夠的空間，因爲它的一些祖先引入了額外的水平填充。爲了實現您的目標，您可以確定運行時的寬度。您只需計算設備的寬度並減去正確的填充量即可。例如：

DisplayMetrics displayMetrics = context.getResources().getDisplayMetrics(); 
width = displayMetrics.widthPixels/displayMetrics.density; 
adView.setAdSize(new AdSize(width - padding, 100)); 

重要的是要注意，這裏的值是dip（密度獨立像素），而不是像素。
