如何防止TextView调整父级LinearLayout的大小 - Android

Question

我有LinearLayout覆盖屏幕的整个宽度，我有一个随机数TextView（本例中为7）。我希望TextView的所有内容都相同，因此我将属性android:layout_weight="1"放在每个中。

当TextView中没有文本时，一切正常：

但是当我添加与每个TextView相对应的文字时，Textview的尺寸会发生变化，而不是保持重量并调整LinearLayout

的大小

这只是我的Activity设计的一部分，所以我在一个新的xml中重新创建它以查看错误是否仍然存在。 而且我注意到只有当LinearLayout位于HorizontalScrollView

内时才会发生这种情况

如果不是，我会得到预期的结果：

我的xml：

<HorizontalScrollView
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:fillViewport="true">

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="horizontal">

        <TextView
            android:singleLine="true"
            android:text="LONG TEXT"
            android:layout_marginBottom="1dp"
            android:layout_marginTop="1dp"
