的ImageView的可見性設置爲走了，當用戶將圖像的可見度變爲可見和ImageView的推動下提交按鈕。

但是，結果是不可取的，它使提交按鈕錨佈局的最底部。正如你可以看到：

我的問題是，我怎麼能使這個佈局尊重提交按鈕的底部邊距？

添加layout_marginBottom其父（在這種情況下，ConstraintLayout）可能會奏效。

在我看來，所有這些約束屬性可能會搞砸了利潤率。對於這種佈局，我認爲你不需要ConstraintLayout。 A LinearLayout會做得很好。

我切換到線性佈局，約束和線性佈局都無助於這種情況。我沒有將layout_marginBottom添加到線性和約束佈局。 – Rosenberg

按鈕的'layout_marginBottom'屬性正在工作。按鈕下方的黑色空格是一個邊距（請注意，您的滾動視圖具有黑色背景）。你的問題在這裏可能是你的'ConstraintLayout'的高度。它的高度是0dp，並將變成其子女的身高。也許如果你把它放到'match_parent'，你會得到你想要的綠色背景 –

我也面臨着同樣的問題，它是由包木窗與另一個LinearLayout中沒有利潤的子佈局的解決。在你的情況下，它會像

保證金問題只滾動型的根的孩子，你可以添加邊距內孩子造成的。
