walkthrough_single_view.xml:

<?xml version="1.0" encoding="utf-8"?> <imageview xmlns:android="http://schemas.android.com/apk/res/android"     android:id="@+id/image_view"     android:layout_width="fill_parent"     android:layout_height="fill_parent" />

and how looks (the image 1080*1920):

edit: want mini tutorial. 1 page images, 1 page movie. think best way?

try this:

int devicewidthinpixels = getresources().getdisplaymetrics().widthpixels; int deviceheightinpixels = getresources().getdisplaymetrics().heightpixels; imageview.getlayoutparams().width = devicewidthinpixels; imageview.getlayoutparams().height = deviceheightinpixels; 

also, use viewpager:

<android.support.v4.view.viewpager     android:id="@+id/view_pager"     android:layout_width="fill_parent"     android:layout_height="fill_parent" />  

and imageview

<?xml version="1.0" encoding="utf-8"?> <imageview xmlns:android="http://schemas.android.com/apk/res/android"     android:id="@+id/image_view"     android:layout_width="fill_parent"     android:layout_height="fill_parent"     android:scaletype="fitxy" />
