    copied!<p>I have made a simple application, with a background image, 4 image buttons and 4 text views in front of them. </p> <p>I've read the google development documentation, but I still don't understand why in screens with a different size of 4,7" the app doesn't run normally. The textview is not in the right place. The image buttons are too small or too big in wrong places </p> <p>I've created different images for differente resolutions (ldpi, mdpi, hdpi,xhdpi).</p> <p>Here is the xml file:</p> <pre><code>&lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/RelativeLayout1" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@drawable/gameinterface" android:gravity="center_vertical" android:orientation="vertical" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context=".QuestionsActivity" &gt;
