Support screen issue
<p>I added support screen for different sizes for the devices but when i test it it seems that the buttons are a bit up,not like in the preview(I have the same phone as the preview).</p>

<p>Here's the layout for my phone specs:</p>

<p><div class="snippet" data-lang="js" data-hide="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
    android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivity"
    android:background="@drawable/backgroundapp"
    android:orientation="vertical"&gt;


    &lt;ImageButton
        android:id="@+id/btnSwitch"
        android:layout_width="110dp"
        android:layout_height="120dp"
        android:src="@drawable/poweroffline"
        android:background="@null"
        android:contentDescription="@null"
        android:layout_marginTop="64dp"
        android:scaleType="fitXY"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:clickable="false" /&gt;

    &lt;ImageButton
        android:id="@+id/FlashBlinkButton"
        android:layout_width="75dp"
        android:layout_height="100dp"
        android:src="@drawable/blinkoffline"
        android:background="@null"
        android:contentDescription="@null"
        android:scaleType="fitCenter"
        android:layout_below="@+id/btnSwitch"
        android:layout_alignLeft="@+id/AlarmButton"
        android:layout_alignStart="@+id/AlarmButton"
        android:layout_marginTop="12dp" /&gt;

    &lt;ImageButton
        android:layout_width="75dp"
        android:layout_height="60dp"
        android:id="@+id/AlarmButton"
        android:src="@drawable/alarmoffline"
        android:background="@null"
        android:contentDescription="@null"
        android:scaleType="fitXY"
        android:layout_marginTop="19dp"
        android:layout_below="@+id/FlashBlinkButton"
        android:layout_centerHorizontal="true" /&gt;

&lt;/RelativeLayout&gt;</code></pre>
</div>
</div>
</p>

<p>I also have another device where it's like the other one a bit up even when i put the configuration qualifiers .</p>
