Remove Blank Space from page viewer in UniversalImageLoader

Question

I am using Universal Image Loader v 1.9.1 . I am getting blank space at the start and end of image(horizontally).Cant figure out how to get imageview occupy full width of screen. could this be an issue with images?

MY code Snippets are:

ac_image_pager.xml

<android.support.v4.view.ViewPager
             android:id="@+id/pager"
             android:layout_width="match_parent"
             android:layout_height="200dp"  
         />

item_pager_image.xml

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="200dp"
    >

    <ImageView
        android:id="@+id/image"
        android:layout_width="match_parent"
        android:layout_height="200dp"
        android:adjustViewBounds="true"
        android:contentDescription="@string/descr_image" />

    <ProgressBar
        android:id="@+id/loading"
        android:layout_width="wrap_content"
        android:layout_height="200dp"
        android:layout_gravity="center"
        android:visibility="gone" />

</FrameLayout>

ImagePagerActivity.java

Following init configs for pageviewer

options = new DisplayImageOptions.Builder()
            .showImageForEmptyUri(R.drawable.ic_empty)
            .showImageOnFail(R.drawable.ic_error)
            .resetViewBeforeLoading(true)
            .cacheOnDisc(true)
            .imageScaleType(ImageScaleType.EXACTLY_STRETCHED)
            .bitmapConfig(Bitmap.Config.RGB_565)
            .considerExifParams(true)
            .displayer(new FadeInBitmapDisplayer(300))
            .build();

Answer 1

Although you've specified the ImageView's width to match_parent, the height is fixed to 200dp. This means if the image ratio is restricted to the height in respect to its container, the image will be horizontally padded to maintain the aspect ratio.

There are different ways to solve your problem:

• Set the ImageView's scaleType to fitXY to allow the image to stretch regardless of its aspect ratio.
• Set the ImageView's height to wrap_content to allow the height to be determined dynamically. Beware that the ViewPager's height should cope with this, for instance by being set to match_parent.
• Allow pages of the ViewPager to overlap.

Answer 2

Try this for image

 android:layout_width="match_parent"
            android:layout_height="200dp"
            android:scaleType="fitXY"
