java - 线性布局网格在模拟器中显示但在设备上不显示，可能是什么原因？

Question

我目前运行的 Activity 在模拟器 (Nexus 5X API 27) 上运行良好，但是在设备 (Samsung S8 Plus) 上执行时；线性布局网格不会出现。我已经添加了适当的约束，但它们仍然没有显示。

尝试移动 TextView 为线性布局网格腾出更多空间，但仍然没有用。

Answer 1

我认为您的布局超出了屏幕尺寸但没有滚动。您已经为某些布局元素分配了固定大小。尝试使用 nestedScrollView 封闭 constraintLayout。

但还要注意一件事:

<LinearLayout
    android:id="@+id/linIconGrid"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginStart="10dp"
    android:layout_marginTop="16dp"
    android:layout_marginEnd="10dp"
    android:orientation="vertical"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toBottomOf="@+id/textPointsBadge">

为什么将 match_parent 用于 constraintLayout 的直接子项？如果你想使用全宽设置宽度为 0dp 并使用这些

   app:layout_constraintEnd_toEndOf="parent"
   app:layout_constraintStart_toStartOf="parent"
