Q:

Different resolution in android

I have layout with two Plain Text.  This is code:
 <EditText
            android:id="@+id/editTextName"
            android:layout_width="120dp"
            android:layout_height="wrap_content"
            android:layout_alignParentLeft="true"
            android:layout_alignParentTop="true"
            android:layout_marginLeft="26dp"
            android:layout_marginTop="56dp"
            android:hint="Förnamn"
             >

        </EditText>

        <EditText
            android:id="@+id/editTextAdress"
            android:layout_width="200dp"
            android:layout_height="wrap_content"
            android:layout_alignLeft="@+id/editTextName"
            android:layout_below="@+id/editTextName"
            android:layout_marginTop="20dp" 
            android:hint="Gatuadress">

        </EditText>

I have a problem with resolution.  When I use emulator in 3,7in looks great but when I change on 10.1in(tablet) my Plain texts are very small.  How I can do that in every relolution my Plain Texts looks the same? 
This is photos for better understanding:

I want to this Plain text looks the same on resolution for tablets and smaller screens. 

A:

Try setting the text size using sp:
android:textSize="20sp"

This page explains how to handle multiple resolutions, and also what the sp units are and how they work:
