Android LinearLayout 高度与元素的宽度不成比例
Android LinearLayout height is not proportional to element's width
我想在任何屏幕尺寸上将我的 5 个按钮均匀地排成一行。为此,我做了以下布局:
<FrameLayout 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"
android:background="@drawable/main_background_v3"
tools:context="com.magnifi.pennantrace.training.TrainingSelectFragment">
<android.support.constraint.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:weightSum="5"
android:layout_marginTop="16dp"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintLeft_toLeftOf="parent">
<ImageButton
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:background="@mipmap/training_stretch"
android:layout_weight="1"/>
<ImageButton
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:background="@mipmap/training_mechanics"
android:layout_weight="1"/>
<ImageButton
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:background="@mipmap/training_cardio"
android:layout_weight="1"/>
<ImageButton
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:background="@mipmap/training_weights"
android:layout_weight="1"/>
<ImageButton
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:background="@mipmap/training_batfield"
android:layout_weight="1"/>
</LinearLayout>
</android.support.constraint.ConstraintLayout>
</FrameLayout>
它达到了我的要求,但现在高度不正确。所有按钮图像均为正方形。这是我得到的:
如何设置合适的高度(与按钮宽度成比例)?
将下面编写的代码替换为您的代码将解决您的问题。

如果您使用线性布局和权重,请不要忘记填充所有必要的文件夹:xxxhdpi、xxhdpi、xhdpi、hdpi、mdpi!
