I have a android view with 2 buttons centered. I want to change the button sizes to be bigger when I run the app on a tablet because they look ridiculous small there since it is the same size as for the phones.

How can I do this?

This is my code:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:background="#e9e9e9"
                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" >

    <ImageView android:id="@+id/imageView1"
               android:layout_height="wrap_content"
               android:layout_width="wrap_content"
               android:layout_centerInParent="true"
               android_layout_gravity= "center"
               android:layout_marginLeft="30dp"
               android:layout_marginRight="30dp"
               android:src="@drawable/icon_bakgrund_android">
    </ImageView>

    <RelativeLayout

            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            >

        <TableLayout
                xmlns:android="http://schemas.android.com/apk/res/android"
                android:id="@+id/TableLayout01"
                android:layout_height="wrap_content"
                android:layout_width="wrap_content"
                android:layout_centerInParent="true"
                >


        <TableRow android:id="@+id/TableRow01"
                  android:layout_width="wrap_content"
                  android:layout_height="wrap_content">

            <Button
                    android:id="@+id/button1"
                    android:layout_width="260dp"
                    android:layout_height="50dp"
                    android:background="@drawable/nybutton"
                    android:layout_below="@+id/button2"
                    android:text="@string/las_sollefteabladet"
                    android:textColor="#ffffff"
                    android:layout_centerHorizontal="true"/>


        </TableRow>
