Question

In my app, when I click a button I was supposed to move to a new page, and it shows an image. The size of the image is width 480pixels and height is 1257 pixels. The image is very clear in landscape mode where as in portrait mode it seems to be stretched. but i need to be perfect in both the sides.

The follwing is the xml code

<?xml version="1.0" encoding="UTF-8"?>
<AbsoluteLayout
android:id="@+id/finalPage"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android"
>
<ScrollView android:id="@+id/ScrollView01"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >

<LinearLayout android:id="@+id/LinearLayout02"
        android:layout_width="wrap_content"
        android:layout_height="30px"
        android:orientation="vertical"
        >

<ImageView
android:id="@+id/widget41"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_x="0px"
android:layout_y="0px"
>
</ImageView>
</LinearLayout>>
</ScrollView>>
</AbsoluteLayout>

this is to be part of my source code

public class HelpPage extends Activity 
{
    ImageView BackGroundImage;
    int width,height,orientation;

//  ImageView help;
    public void onCreate(Bundle icicle) 
    {
    super.onCreate(icicle);

    DisplayMetrics displaymetrics = new DisplayMetrics();
    getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);

    setContentView(R.layout.help);

    height = displaymetrics.heightPixels;
    width = displaymetrics.widthPixels;

    WebView webview;
    webview = (WebView) findViewById(R.id.webview);
//  webview.loadUrl("file:///android_asset/helptext.html");

    Log.e("FirstImage", "Width = "+width+"Height = "+height+" orientation= "+orientation);

    BackGroundImage = (ImageView) findViewById(R.id.widget41);
    BackGroundImage.setBackgroundResource(R.drawable.help);


     if(width == 320 && height == 480)
     {
         BackGroundImage.setBackgroundResource(R.drawable.help);
     }

     //Landscape mode of 320x480
     else if(width == 480 && height == 320)
     {
         BackGroundImage.setBackgroundResource(R.drawable.help);
     }

     //portrait mode of 480x800
     else if(width == 480 && height == 800)
     {
            BackGroundImage.setBackgroundResource(R.drawable.help);
     }

   //Landscape mode of 480x800
    else if(width == 800 && height == 480)
     {
        BackGroundImage.setBackgroundResource(R.drawable.help1);
     }

   //portrait mode of 480x854
     else if(width == 480 && height == 854)
     {      
       BackGroundImage.setBackgroundResource(R.drawable.help);
     }

   //Landscape mode of 480x854
    else if(width == 854 && height == 480)
     {
        BackGroundImage.setBackgroundResource(R.drawable.help1);
     }


//  help = new ImageView(this);
//  help = (ImageView)findViewById(R.id.helps);
    }
}

How can i solve this issue?

I think that is not the way to handle this, Android can do this for you in an easier way. I recommend you read carefully this android support page: http://developer.android.com/guide/practices/screens_support.html
