如何全屏显示图像

Question

I have an image and I need it to be shown with its full view as it is. But the image is shown in the phone after loading is reduced to fit the screen. how do I include the image in full size and resolution as it is so that it can be scrolled to see the width?

Here is my layout file:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#EEEEEE">

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android" 
 android:scrollbars="vertical" 
 android:layout_height="wrap_content" 
 android:layout_width="fill_parent"
 android:background="#77aa88">

<LinearLayout 
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center"
android:background="#FFFFFF">

<TextView   android:text="Xkcd"
        android:textColor="#6E7B91"
        android:textSize="28dp"
        android:textScaleX="1.8"

        android:id="@+id/TextHead" 
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content"
        android:paddingTop="10dp"
        android:paddingBottom="10dp"
        android:gravity="center" />

<TextView   android:text="A webcomic of romance, sarcasm, math, and language."
        android:textColor="#000000"
        android:textSize="15dp"
        android:textScaleX="1.1"
        android:id="@+id/TextSub" 
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content"
        android:paddingTop="5dp"
        android:paddingBottom="10dp"
        android:gravity="center" />
</LinearLayout>
</ScrollView>

<ScrollView 
 android:scrollbars="horizontal" 
 android:layout_height="match_parent" 
 android:layout_width="wrap_content">

        <ImageView  android:id="@+id/MainImage" 
                    android:layout_width="fill_parent" 
                    android:layout_height="fill_parent"/>


</ScrollView>

</LinearLayout>

Try using the matrix scaleType :

<ImageView  android:id="@+id/mainimage" 
            android:layout_width="wrap_content" 
            android:layout_height="wrap_content"
            android:src="@drawable/mainimage"
            android:scaleType="matrix"/>
