Question

我正在尝试在 android 的矩形中绘制垂直线和水平线。我的代码已准备好绘制矩形，但在绘制水平线和垂直线时遇到问题

我绘制矩形的代码

<?xml version="1.0" encoding="UTF-8"?>
<shape
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/rectangle_background_shape">
    <stroke android:width="3dp" android:color="#0000FF"  />
    <padding android:left="0dp"
        android:top="0dp"
        android:right="0dp"
        android:bottom="0dp" />
    <corners android:radius="2dp" />
</shape>

我正在尝试绘制下面的图像

如果您使用的是 ConstraintLayout，请尝试以下代码

<?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"
 xmlns:tools="http://schemas.android.com/tools"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:padding="10dp">

<androidx.constraintlayout.widget.ConstraintLayout
    android:layout_width="0dp"
    android:layout_height="0dp"
    android:background="@drawable/lay_bg"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent">

    <View
        android:layout_width="3dp"
        android:layout_height="0dp"
        android:background="#0000FF"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

    <View
        android:layout_width="0dp"
        android:layout_height="3dp"
        android:background="#0000FF"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />
 </androidx.constraintlayout.widget.ConstraintLayout>
 </androidx.constraintlayout.widget.ConstraintLayout>

如果您想在该框中做一些单独的事情，请尝试 GridView 或 RecyclerView 并带有 GridLayoutManager 检查 this

注意：android:background="@drawable/lay_bg" 是矩形的可绘制对象

如果你想用 LinearLayout 试试下面的代码

<?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"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="10dp">

<LinearLayout
    android:layout_width="0dp"
    android:layout_height="0dp"
    android:background="@drawable/lay_bg"
    android:orientation="vertical"
    android:weightSum="2"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:weightSum="2">

        <LinearLayout
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="1" />

        <View
            android:layout_width="3dp"
            android:layout_height="match_parent"
            android:background="#0000FF" />

        <LinearLayout
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="1" />
    </LinearLayout>

    <View
        android:layout_width="match_parent"
        android:layout_height="3dp"
        android:layout_gravity="center"
        android:background="#0000FF" />

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:weightSum="2">

        <LinearLayout
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="1" />

        <View
            android:layout_width="3dp"
            android:layout_height="match_parent"
            android:background="#0000FF" />

        <LinearLayout
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="1" />
    </LinearLayout>

</LinearLayout>
</androidx.constraintlayout.widget.ConstraintLayout>
