ImageView的宽度不匹配父

Question

我想每个人在3个部分使用LinearLayout有：

<?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> 

一切似乎都很正常，但是中间部分的Image，它不匹配父大小，它在左边&右侧有空位，其他部分都很好！ ，这里做错了什么？

我想你的布局和一切工作的完美：

<?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"> 

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

    <ImageView 
     android:layout_width="match_parent" 
     android:layout_height="60dp" 
     android:background="#343434"/> 

</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:background="#654321" 
     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/common_ic_googleplayservices" /> 

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

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

    <ImageView 
     android:id="@+id/undo"

     android:layout_height="wrap_content" 
     android:clickable="true" 
     android:src="@drawable/common_ic_googleplayservices" /> 

</LinearLayout>
