用高程完成两个面板布局的最有效方法是什么？

Question

所以，我尝试了使用 ConstraintLayout 的不同变体以尽可能保持平坦，但下面的代码是我能做到的最好的。此外，我还需要添加一个ScrollView 作为布局父级。如果有人可以帮助我，我将不胜感激。提前致谢！

这是我目前拥有的xml：

这就是我想要完成的：

Answer 1

你可以使用这个代码：

<ScrollView 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:orientation="vertical">

<LinearLayout
    android:id="@+id/layout"
    android:layout_width="match_parent"
    android:layout_height="222dp"
    android:orientation="vertical">

    <androidx.constraintlayout.widget.ConstraintLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <TextView
            android:id="@+id/textView2"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginStart="8dp"
            android:layout_marginLeft="8dp"
            android:layout_marginTop="8dp"
            android:layout_marginEnd="8dp"
            android:layout_marginRight="8dp"
            android:layout_marginBottom="8dp"
            android:text="TextView"
            app:layout_constraintBottom_toBottomOf="parent"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintHorizontal_bias="0.498"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toTopOf="parent" />
    </androidx.constraintlayout.widget.ConstraintLayout>
</LinearLayout>

您可以将现有代码放入 ScrollView，但问题是您将无法设置 LinearLayout height="match_parent"，因此我建议将其设置为任何默认值，然后在您的活动集中它的高度在语法上是当前用户手机屏幕的高度乘以 3，使用如下代码：

LinearLayout layout = (LinearLayout) findViewById(R.id.layout);
DisplayMetrics metrics = new DisplayMetrics();
linearLayout.getLayoutParams().height = metrics.heightPixels * 3;

是的，这是一种硬代码）））我确信你的布局不会超过 3 种屏幕尺寸...试试吧，它必须有效）））

Answer 2

您可以尝试像这样使用带有指南和 cardView 的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"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
android:id="@+id/frameLayout2"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/color"
tools:context=".Fragments.MenusDesign.ExpandableCategoriesMenu.ExpandableCategoriesMenu"
xsi:schemaLocation="http://schemas.android.com/apk/res/android ">


<androidx.cardview.widget.CardView
    android:id="@+id/cardView"
    android:layout_width="0dp"
    android:layout_height="0dp"
    android:layout_marginStart="8dp"
    android:layout_marginTop="8dp"
    android:layout_marginEnd="8dp"
    android:layout_marginBottom="8dp"
    android:background="@color/colorAccent"
    app:layout_constraintBottom_toTopOf="@+id/guideline2"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintHorizontal_bias="1.0"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent"
    app:layout_constraintVertical_bias="1.0" />

<TextView
    android:id="@+id/tv_header"
    android:layout_width="342dp"
    android:layout_height="30dp"
    android:layout_marginStart="8dp"
    android:layout_marginTop="8dp"
    android:layout_marginEnd="8dp"
    android:elevation="2dp"
    android:text="Hello there, help us fill out this information"
    app:layout_constraintEnd_toEndOf="@+id/cardView"
    app:layout_constraintStart_toStartOf="@+id/button4"
    app:layout_constraintTop_toTopOf="@+id/cardView" />







<androidx.constraintlayout.widget.Guideline
    android:id="@+id/guideline2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    app:layout_constraintGuide_percent="0.5" />


<Button
    android:id="@+id/bt_confirm_button"
    android:layout_width="272dp"
    android:layout_height="48dp"
    android:layout_marginStart="28dp"
    android:layout_marginEnd="8dp"
    android:layout_marginBottom="16dp"
    android:layout_weight="0"
    android:elevation="2dp"
    android:text="CONFIRM"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent" />

<TextView
    android:id="@+id/textView5"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_marginStart="8dp"
    android:layout_marginTop="8dp"
    android:layout_marginEnd="8dp"
    android:text="Make sure to keep all your info private"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toBottomOf="@+id/cardView" />

<Button
    android:id="@+id/button3"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_marginBottom="8dp"
    android:elevation="2dp"
    android:text="phone number"
    app:layout_constraintBottom_toBottomOf="@+id/cardView"
    app:layout_constraintEnd_toEndOf="@+id/button4"
    app:layout_constraintStart_toStartOf="@+id/button4" />

<Button
    android:id="@+id/button4"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_marginTop="8dp"
    android:layout_marginBottom="8dp"
    android:elevation="2dp"
    android:text="Button"
    app:layout_constraintBottom_toTopOf="@+id/button3"
    app:layout_constraintEnd_toEndOf="@+id/cardView"
    app:layout_constraintStart_toStartOf="@+id/cardView"
    app:layout_constraintTop_toBottomOf="@+id/button5" />

<Button
    android:id="@+id/button5"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_marginTop="8dp"
    android:layout_marginEnd="8dp"
    android:text="Name"
    app:layout_constraintEnd_toEndOf="@+id/button4"
    app:layout_constraintStart_toStartOf="@+id/button4"
    app:layout_constraintTop_toBottomOf="@+id/tv_header" />

现在您需要做的就是为您的 cardView 提供您的设计（阴影、颜色等...），并且您的屏幕上半部分很好地提升了，而无需在内部使用任何嵌套布局。

您的布局将如下所示：
