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

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水平设置Textview和Imageview.

2.Textview不会到达Imageview的中间(中间).(左右位置)

3.Also布局比重,没有努力使TextView的中心,由于Cosntraint布局

帮助我实现这一目标.

提前致谢.

如果您希望ImageView在父项的右侧删除此属性:

app:layout_constraintLeft_toLeftOf="@+id/title1"

如果要垂直对齐,请TextView添加以下属性:

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>
</android.support.v7.widget.CardView>

结果:
