应用程序不使用全宽屏幕（Actionbar）(App does not use full width of screen (Actionbar))
当涉及到我的应用程序（附件）的宽度时，我遇到了问题。 似乎我没有使用屏幕的整个宽度，因为我正在使用操作栏，并且“设置”菜单出现的空间占据了屏幕的剩余宽度。 有没有办法使用全宽，因为我还没有使用“设置”菜单？

I am facing a problem when it comes to the width of my app (attachment). It seems that the full width of the screen is not used since I am using a actionbar, and that the space where the "Settings" menu would appear is taking the remaining width of the screen. Is there any way to use the full width since I am not using the "Settings" menu anyway?

最满意答案
你为布局赋予了宽度和高度常量，对于ConstraintLayout， match_parent给出了0dp并添加了所有必要的约束
<RelativeLayout android:id="@+id/master_fragment" android:layout_width="0dp" android:layout_height="0dp" app:layout_constraintBottom_toBottomOf="parent" app:layout_constraintStart_toStartOf="parent" app:layout_constraintTop_toTopOf="parent" app:layout_constraintEnd_toEndOf="parent" > </RelativeLayout>You gave width and height constant to the layout, for ConstraintLayout match_parent give 0dp and add all necessary constraints
<RelativeLayout android:id="@+id/master_fragment" android:layout_width="0dp" android:layout_height="0dp" app:layout_constraintBottom_toBottomOf="parent" app:layout_constraintStart_toStartOf="parent" app:layout_constraintTop_toTopOf="parent" app:layout_constraintEnd_toEndOf="parent" > </RelativeLayout>更多推荐
