用高程完成兩個面板布局的最有效方法是什么？

Question

因此，我使用ConstraintLayout嘗試了不同的變體以使其盡可能保持平坦，但下面的代碼是我能完成的最好的。 此外，我需要添加一個ScrollView作為布局父項。 如果有人可以幫助我，我將不勝感激。 提前致謝！

這是我目前擁有的 xml：

這就是我想要完成的：

Answer 1

您可以使用此代碼：

<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>

您可以將現有代碼放入 ScrollView，但問題是您將無法設置 LinearLayout height="match_parent"，因此我建議將其設置為任何默認值，然后在您的活動中按語法設置它的高度作為當前用戶手機屏幕的高度乘以 3，使用如下代碼：

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

是的，它是一種硬代碼 ))) 我相信你的布局不會超過 3 個屏幕尺寸......試試吧，它必須工作 )))

Answer 2

您可以嘗試使用帶有指南和 cardView 的 constLayout ，如下所示：

<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

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_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" />

現在您需要做的就是為您的 cardView 提供您的設計（陰影、顏色等...），並且您可以在不使用任何嵌套布局的情況下很好地提升屏幕的上半部分。

您的布局將如下所示：
