调整其中的ImageView大小后，调整LinearLayout或RelativeLayout的大小

Question

I have to put an ImageView inside a RelativeLayout. Just like this:

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">
    <ImageView
            android:id="@+id/imagen"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:scaleType="centerInside"
            android:src="@drawable/image1"/>
</RelativeLayout>

I know that this image will be resized in some devices because it would be too big for the device's screen. The remaining resized layout is something like this , notice the gray area around the image, wich is the original RelativeLayout BEFORE resizing, I think!

How can I remove that remaining space? Thanks!

Try this

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <ImageView
            android:id="@+id/imagen"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:scaleType="centerCrop"
            android:src="@drawable/image1"/>
</RelativeLayout>
