Question

我希望我的textview和imageview像上面提到的图像。

1.我想使用约束布局在单行中设置 Textview和Imageview水平。

2.Textview未来到Imageview的中间（中间）。（左右位置）

3.由于Cosntraint布局，布局重力也无法使 textview center

4.帮助我实现这一目标。

提前致谢。

Answer 1

如果您希望父级右侧的ImageView删除此属性：

app:layout_constraintLeft_toLeftOf="@+id/title1"

如果你想垂直对齐，TextView添加这些属性：

app:layout_constraintTop_toTopOf="@id/display_pic"
app:layout_constraintBottom_toBottomOf="@id/display_pic"

带有更改的xml：

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView
    android:id="@+id/cv2"
    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="wrap_content"
    android:layout_gravity="center"
    app:cardCornerRadius="4dp"
    app:layout_constraintTop_toBottomOf="@+id/cv1">

    <android.support.constraint.ConstraintLayout
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <TextView
            android:id="@+id/title1"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:paddingLeft="10dp"
            android:text="Hero"
            android:textColor="@color/colorPrimary"
            android:textSize="16dp"
            android:textStyle="bold"
            app:layout_constraintTop_toTopOf="@id/display_pic"
            app:layout_constraintBottom_toBottomOf="@id/display_pic"
            app:layout_constraintLeft_toLeftOf="parent"
            app:layout_constraintRight_toLeftOf="@+id/display_pic"/>


        <ImageView
            android:id="@+id/display_pic"
            android:layout_width="80dp"
            android:layout_height="80dp"
            android:layout_alignParentEnd="true"
            android:adjustViewBounds="false"
            android:scaleType="centerCrop"
            app:layout_constraintRight_toRightOf="parent"
            app:layout_constraintTop_toTopOf="parent"
            app:srcCompat="@android:color/holo_red_light"/>

    </android.support.constraint.ConstraintLayout>

使用上面的代码，您可以将textview保持在图像视图的中心。要定位图像视图，请调整垂直和水平偏差。希望这会有所帮助。

Android约束布局中心水平对齐Textview和Imageview不工作
