<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res-auto"

            android:textAlignment="center"
            android:layout_weight="1"/>

</LinearLayout>


</android.support.constraint.ConstraintLayout>

Answer 1

您的问题是由ConstraintLayout引起的。如果您不需要它，只需删除并让LinearLayout成为父

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:orientation="vertical">

    <TextView
        android:gravity="center"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:text="Add Pills"
        android:textSize="50sp"
        android:textAlignment="center"
        android:layout_weight="1"/>

    <TextView
        android:gravity="center"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:text="Edit Pills"
        android:textSize="50sp"
        android:textAlignment="center"
        android:layout_weight="1"/>
</LinearLayout>

Answer 2

将最外层布局设为LinearLayout而不是ConstraintLayout
删除内部主LinearLayout（您不需要它，因为外部线性布局可以做您想要的）
权重LinearLayout和TextView的文字视图height为0，width为match_parent，因此可以根据屏幕进行调整< / LI>

Answer 3

要充分利用layout_weight，请将height设置为0dp。此外，将两个文本视图都设置为高度match_parent会使事情变得混乱

<TextView
        android:gravity="center"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:text="Add Pills"
        android:textSize="50sp"
        android:textAlignment="center"
        android:layout_weight="1"/>

    <TextView
        android:gravity="center"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:text="Edit Pills"
        android:textSize="50sp"
        android:textAlignment="center"
        android:layout_weight="1"/>

似乎你在约束布局和带有权重属性的线性布局之间混乱。同时我订了一些订单，请查看是否符合您的要求。我不 - 请更好地解释你的需求：

    <?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="0dp">


    <TextView
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="0.5"
        android:gravity="center"
        android:text="Add Pills"
        android:textAlignment="center"
        android:textSize="50sp" />

    <TextView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_weight="0.5"
        android:gravity="center"
        android:text="Edit Pills"
        android:textAlignment="center"
        android:textSize="50sp" />


    </LinearLayout>
