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？
Linear Layout grid showing in emulator but not on device, what could be cause?
我目前 运行 activity 在模拟器 (Nexus 5X API 27) 上运行良好，但是在设备 (Samsung S8 Plus) 上执行它时；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。
尝试移动文本视图，为线性布局网格创建更多 space，但仍然没有用。

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">
为什么要使用 match_parent 作为 constraintLayout 的直接子项？如果要使用全宽，请将宽度设置为 0dp 并使用这些
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
我发现使用的图像太大（就容量而言，例如每个 7mb）。我缩小了图像的尺寸，一切都开始正常工作。
我目前 运行 activity 在模拟器 (Nexus 5X API 27) 上运行良好，但是在设备 (Samsung S8 Plus) 上执行它时；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。
尝试移动文本视图，为线性布局网格创建更多 space，但仍然没有用。

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">
为什么要使用 match_parent 作为 constraintLayout 的直接子项？如果要使用全宽，请将宽度设置为 0dp 并使用这些
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
我发现使用的图像太大（就容量而言，例如每个 7mb）。我缩小了图像的尺寸，一切都开始正常工作。
