Android Full Screen on Tablet
<p>I've developed an app on Android. The screen displays well on the mobile phone - eg shows full screen. But when I run it on my Samsung tablet 10 inch - it covers only a quarter of the screen. Here is my layout file:</p>

<pre><code>&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
                android:layout_width="fill_parent" 
                android:layout_height="wrap_content"
                android:background="@drawable/background"
                android:padding="10px"&gt;
    &lt;AbsoluteLayout xmlns:android="http://schemas.android.com/apk/res/android"
                    android:layout_width="fill_parent" 
                    android:layout_height="wrap_content"

                    android:gravity="center" &gt;
        &lt;ImageView
android:id="@+id/mainheader"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_x="30px"
android:layout_y="5px"
android:src="@drawable/mainheader"
/&gt;

        &lt;TextView android:id="@+id/err"
                        android:layout_width="wrap_content"
                        android:layout_height="wrap_content"   
                        android:textColor="#FF0000"
 android:layout_x="80px"
android:layout_y="25px" /&gt;
        &lt;TextView android:id="@+id/usernamelbl"
                        android:layout_width="wrap_content"
                        android:layout_height="35px"
                        android:text="User Name"
                         android:layout_x="40px"
    android:layout_y="75px"/&gt; 
        &lt;EditText android:id="@+id/username" 
                        android:layout_width="150px" 
                        android:layout_height="wrap_content" 
                        android:layout_below="@id/err"  
                        android:background="@android:drawable/editbox_background"
                        android:singleLine="true"
                                             android:layout_x="120px"
    android:layout_y="70px"/&gt;
        &lt;TextView android:id="@+id/passwordlbl"
                        android:layout_width="wrap_content"
                        android:layout_height="wrap_content"
                        android:text="Password" 
                        android:layout_x="40px"

        &lt;EditText android:id="@+id/password" 
                        android:layout_width="150px" 
                        android:layout_height="wrap_content" 
                        android:background="@android:drawable/editbox_background"
                        android:layout_x="120px"
    android:layout_y="105px"
                        android:password="true"
                        android:singleLine="true"/&gt;
        &lt;Button android:id="@+id/loginBtn"
                        android:text="Login"
                        android:layout_width="wrap_content"
                        android:layout_height="wrap_content"
                        android:onClick="login_click"

    android:layout_y="150px"
                        /&gt;
        &lt;Button android:id="@+id/signupBtn"
                        android:text="Sign Up"

                        android:onClick="signUp_click"
                                                         android:layout_x="130px"
    android:layout_y="150px"/&gt;
    &lt;/AbsoluteLayout&gt;
&lt;/LinearLayout&gt;
