Question

我想使用ConstraintLayout创建此布局：

“我的设备”位于左上角，“卧室”位于右上角，用户图标位于布局的左侧，“我的设备”下方。这三个项目可以使用ConstraintLayout确定。问题在于右中内容区域，包括“ 20:30”和一个imageview。

我希望它们位于“卧室”和“我的设备”下方以及用户图标右侧的区域中。我的布局文件如下：

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout     xmlns:android="http://schemas.android.com/apk/res/android"

</RelativeLayout>

<CheckBox

    android:maxWidth="8dp"
    android:maxHeight="8dp"
    android:visibility="gone"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintDimensionRatio="1,1"
    app:layout_constraintRight_toRightOf="parent" />
</android.support.constraint.ConstraintLayout>

但是，布局的预览位于android studio中的下方：

中右内容区域似乎与“卧室”重叠，并且不应该位于“卧室”下方。

如何使用ConstrantLayout创建此布局？

因此您可以进行如下操作：

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="255dp"
    android:layout_height="70dp"
    xmlns:app="http://schemas.android.com/apk/res-auto">

    <TextView
        android:id="@+id/myDevice"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="My device"
        android:layout_margin="8dp"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintStart_toStartOf="parent"/>

    <ImageView
        android:id="@+id/img1"
        android:layout_width="wrap_content"
        android:layout_height="0dp"
        android:src="@mipmap/ic_launcher"
        app:layout_constraintTop_toBottomOf="@+id/myDevice"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintBottom_toBottomOf="parent"/>

    <TextView
        android:id="@+id/clock"
        android:layout_width="0dp"
        android:layout_height="0dp"
        android:gravity="center"
        android:text="20:30"
        android:textSize="24sp"
        app:layout_constraintTop_toTopOf="@id/img1"
        app:layout_constraintBottom_toBottomOf="@id/img1"
        app:layout_constraintStart_toEndOf="@id/img1"
        app:layout_constraintEnd_toStartOf="@id/img2"/>

    <TextView
        android:id="@+id/Bedroom"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Bedroom"
        android:layout_marginEnd="8dp"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintTop_toTopOf="@id/myDevice"/>


    <ImageView
        android:id="@+id/img2"
        android:layout_width="0dp"
        android:layout_height="0dp"
        android:src="@mipmap/ic_launcher"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintTop_toBottomOf="@id/Bedroom"
        app:layout_constraintStart_toEndOf="@id/clock"/>

</android.support.constraint.ConstraintLayout>
