如何在线性布局中放置 4 种颜色

Question

您能否指导我如何在线性布局中放置 4 种颜色，而不是创建 4 个线性布局视图，因为我意识到有更好的方法，但我不知道如何应用它。

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

结果应该如下图所示

最好用ConstraintLayout

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

    <ImageView
            android:id="@+id/imgOne"
            android:layout_width="0dp"
            android:layout_height="0dp"
            android:background="#ff00"
            app:layout_constraintBottom_toTopOf="@+id/imgThree"
            app:layout_constraintEnd_toStartOf="@id/imgTwo"
            app:layout_constraintHorizontal_bias="0.5"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toTopOf="parent" />


    <ImageView
            android:id="@+id/imgTwo"
            android:layout_width="0dp"
            android:layout_height="0dp"
            android:background="#2196F3"
            app:layout_constraintBottom_toTopOf="@+id/imgFour"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintHorizontal_bias="0.5"
            app:layout_constraintStart_toEndOf="@id/imgOne"
            app:layout_constraintTop_toTopOf="parent" />


    <ImageView
            android:id="@+id/imgThree"
            android:layout_width="0dp"
            android:layout_height="0dp"
            android:background="#FFC107"
            app:layout_constraintBottom_toBottomOf="parent"
            app:layout_constraintEnd_toStartOf="@id/imgTwo"
            app:layout_constraintHorizontal_bias="0.5"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toBottomOf="@+id/imgOne" />


    <ImageView
            android:id="@+id/imgFour"
            android:layout_width="0dp"
            android:layout_height="0dp"
            android:background="#FF5722"
            app:layout_constraintBottom_toBottomOf="parent"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintHorizontal_bias="0.5"
            app:layout_constraintStart_toEndOf="@id/imgThree"
            app:layout_constraintTop_toBottomOf="@+id/imgTwo" />


</androidx.constraintlayout.widget.ConstraintLayout>

像这样使用约束布局

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <androidx.constraintlayout.widget.ConstraintLayout
        android:layout_width="0dp"
        android:layout_height="0dp"
        android:background="@color/dark_blue"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintBottom_toTopOf="@id/clThird"
        app:layout_constraintEnd_toStartOf="@id/clSecond"
        app:layout_constraintStart_toStartOf="parent"
        android:id="@+id/clFirst">

    </androidx.constraintlayout.widget.ConstraintLayout>

    <androidx.constraintlayout.widget.ConstraintLayout
        android:layout_width="0dp"
        android:layout_height="0dp"
        android:background="@color/light_gray"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintBottom_toTopOf="@id/clFourth"
        app:layout_constraintStart_toEndOf="@id/clFirst"
        android:id="@+id/clSecond">

    </androidx.constraintlayout.widget.ConstraintLayout>

    <androidx.constraintlayout.widget.ConstraintLayout
        android:layout_width="0dp"
        android:layout_height="0dp"
        android:background="@color/black"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toStartOf="@id/clFourth"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@id/clFirst"
        android:id="@+id/clThird">

    </androidx.constraintlayout.widget.ConstraintLayout>

    <androidx.constraintlayout.widget.ConstraintLayout
        android:layout_width="0dp"
        android:layout_height="0dp"
        android:background="@color/blue_color"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintTop_toBottomOf="@id/clSecond"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toEndOf="@id/clThird"
        android:id="@+id/clFourth">

    </androidx.constraintlayout.widget.ConstraintLayout>

</androidx.constraintlayout.widget.ConstraintLayout>

您可以将线性布局用于垂直和水平方向，权重为 1，如下所示

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1">
        <LinearLayout
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:background="@color/grey1" />
        <LinearLayout
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:background="@color/grey2" />
    </LinearLayout>
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1">

        <LinearLayout
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:background="@color/grey3" />
        <LinearLayout
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:background="@color/grey4" />
    </LinearLayout>
</LinearLayout>
