我有2列的GridLayout。我希望ImageButtons的宽度为屏幕宽度的一半,而高度则应与宽度相同,因为图像是正方形。
这就是我所拥有的,并且我已经使用了这些配置,但是我做不到。 Android开发的新手。
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
<GridLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:columnCount="2">
<ImageButton
android:layout_width="match_parent"
android:layout_rowWeight="1"
android:layout_columnWeight="1"
android:layout_height="match_parent"
android:background="@drawable/food0t"/>
<ImageButton
android:layout_width="match_parent"
android:layout_rowWeight="1"
android:layout_columnWeight="1"
android:layout_height="match_parent"
android:background="@drawable/food0t"/>
</GridLayout>
</ScrollView>

您可以在此设计中使用ConstraintLayout
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".activities.SplashActivity">
<ImageButton
android:id="@+id/img1"
android:layout_width="0dp"
android:layout_height="0dp"
android:background="@color/colorPrimaryDark"
app:layout_constraintDimensionRatio="1:1"
app:layout_constraintEnd_toStartOf="@+id/img2"
app:layout_constraintStart_toStartOf="parent"
android:layout_marginRight="5dp"
app:layout_constraintTop_toTopOf="parent" />
<ImageButton
android:id="@+id/img2"
android:layout_width="0dp"
android:layout_height="0dp"
android:background="@color/black"
android:layout_marginLeft="5dp"
app:layout_constraintDimensionRatio="1:1"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toEndOf="@+id/img1"
app:layout_constraintTop_toTopOf="parent" />
<ImageButton
android:id="@+id/img3"
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_marginTop="10dp"
android:background="@color/colorPrimaryDark"
app:layout_constraintDimensionRatio="1:1"
app:layout_constraintEnd_toStartOf="@+id/img4"
app:layout_constraintStart_toStartOf="parent"
android:layout_marginRight="5dp"
app:layout_constraintTop_toBottomOf="@id/img1" />
<ImageButton
