ImageView宽度与父级不匹配

Question

我尝试使用LinearLayout在彼此之下拥有3个部分：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:ads="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:orientation="vertical"
    tools:context=".ImageEditing">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:gravity="center"
        android:orientation="vertical">

        <com.google.android.gms.ads.AdView
            android:id="@+id/adViewOfEditing"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_margin="0dp"
            ads:adSize="BANNER"
            ads:adUnitId="@string/banner_ad_unit_id" />

    </LinearLayout>

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

        <ImageView
            android:id="@+id/imageEditView"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:adjustViewBounds="true"
            android:layout_margin="0dp"
            android:scaleType="fitXY" />


    </LinearLayout>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"

        android:background="#123456"
        android:gravity="center"
        android:orientation="horizontal">

        <ImageView
            android:id="@+id/view"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:clickable="true"
            android:src="@drawable/qa_gallery" />

        <ImageView
            android:id="@+id/zoom"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:clickable="true"
            android:src="@drawable/qa_camera" />

        <ImageView
            android:id="@+id/erase"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:clickable="true"
            android:src="@drawable/qa_trash" />

        <ImageView
            android:id="@+id/crop"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:clickable="true"
            android:src="@drawable/qa_view_post" />

        <ImageView
            android:id="@+id/undo"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:clickable="true"
            android:src="@drawable/qa_reply_comment" />

    </LinearLayout>

</LinearLayout>

一切似乎都很好，但是中间部分的Image，它与父母尺寸不匹配，左边和右边都有间隙，其他部分都很好！ ，这里有什么问题？

我尝试了你的布局，一切都很完美：
