越小按鈕btnSendPassword和另一個按鈕是btnActive。我試過玩寬度但沒有改變。我相當新，所以任何解釋爲什麼發生這將是很好的，所以然後我知道什麼是錯誤的，如果它再次發生。任何幫助將是美好的。

Answer 1

您應該將您的btnSendPassword按鈕與rlSignInForm左右對齊......然後您將達到您的要求。將btnSendPassword的以下XML片段替換爲btnSendPassword的現有XML片段...您將解決所有問題。

<Button 
    android:id="@+id/btnSendPassword" 
    android:layout_width="175dp" 
    android:layout_height="55dp" 
    android:layout_below="@+id/rlSignInTitle" 
    android:layout_alignLeft="@+id/rlSignInForm" 
    android:layout_alignRight="@+id/rlSignInForm" 
    android:layout_marginTop="180dp" 
    android:background="@drawable/rounded_rect_positive_selector" 
    android:gravity="center" 
    android:text="@string/SEND_PASSWORD" 
    android:textColor="@android:color/white" 
    android:textStyle="bold" 
    android:visibility="gone" /> 

Answer 2

設置android：layout_width =「match_parent」。這應該可以解決你的問題。
