较小的按钮为btnSendPassword，另一个按钮为btnActive。我试过玩宽度但没有改变。我是相当新的，所以任何解释为什么会发生这种情况会很好，所以我知道如果它再次发生了什么是错的。任何帮助都会很精彩。

Answer 1

您应该将btnSendPassword按钮与左侧和右侧的rlSignInForm对齐...然后您将达到您的要求。将btnSendPassword的以下XML代码段替换为btnSendPassword的现有XML代码段...您将解决所有问题。

<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

设置android：layout_width =“match_parent”。这应该可以解决你的问题。
