Android Imageview fill the screen width

Question

Here my layout file:

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:background="#000"
tools:context=".CproductDetails" >

    <LinearLayout
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/shape_bg"
        >

        <ImageView
            android:id="@+id/product_image"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:src="@drawable/ic_tweet_placeholder_photo_dark_error"
            android:scaleType="center" />

        <TextView
            android:id="@+id/product_name"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:textIsSelectable="true"
            android:textColor="#95ab56"
            android:textSize="20sp"
            android:layout_marginTop="7dip" />

        <TextView
            android:id="@+id/product_price"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:textIsSelectable="true"
            android:textSize="20sp"
            android:textColor="#efeeea" />

        <TextView
            android:id="@+id/product_commerce"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:textIsSelectable="true"
            android:textSize="20sp" />

        <TextView
            android:id="@+id/product_city"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:textIsSelectable="true"
            android:textSize="15sp"
            android:layout_marginTop="10dip"
            android:layout_marginBottom="10dip" />

        <TextView
            android:id="@+id/product_township"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:textIsSelectable="true"
            android:textSize="15sp"
            android:visibility="gone"
            android:layout_marginBottom="10dip"
            android:drawableLeft="@drawable/location_place"
            android:drawablePadding="7dip" />

        <TextView
            android:id="@+id/product_website"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:textIsSelectable="true"
            android:autoLink="web"
            android:textSize="15sp"
            android:drawableLeft="@drawable/location_web_site"
            android:drawablePadding="7dip"
            android:visibility="gone" />

         <TextView
            android:id="@+id/product_tel"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:textIsSelectable="true"
            android:textSize="20sp"
            android:drawableLeft="@drawable/device_access_call"
            android:drawablePadding="7dip"
            android:visibility="gone" />

    </LinearLayout>

The result in a phone:

and the result in a 7in tablet:

I want to make the image fill the screen width also in tablet. Like Twitter app for example:

Answer 1

Sounds to me like you want to use android:scaleType="fitCenter" and android:adjustViewBounds="true" on your ImageView.

Answer 2

Thank you to all but none of your answers solve my problem. Finally I used Maurycy Wojtowicz's ScaleImageView class.

This view will auto determine the width or height by determining if the height or width is set and scale the other dimension depending on the images dimension

Answer 3

use android:scaleType="fitXY".

This will scale the image in X and Y independently, so that src matches dst exactly. This may change the aspect ratio of the src.
