Question

I have an image(320×210), I call the image from drawable folder in xml file…in portrait mode its working fine, but while I change the device to LANDSCAPE the image is not fitting prorerly..?? How to resolve that issue..??
Here is my xml code i tried

   <ImageView
        android:id="@+id/imageView2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:scaleType="fitCenter"(here i tried with "fitXY" also)
        android:adjustViewBounds="true"
        android:src="@drawable/srkpic"/>  

And also i tried with this method
protected void onSizeChanged(int w, int h, int oldW, int oldH)
{
}
but this method is available only if we extends with “View” which is not meet my requirement.
Thanks.

Answer 1

use the code below on change of your orientation, where imgHeaderFooter is your bitmap

 imgHeaderFooter.setDensity(1/2);

        int width = imgHeaderFooter.getWidth();
        int height = imgHeaderFooter.getHeight();

        int screenWidth = UseMe.getDispWidth()/2;

        float scaleWidth = ((float) screenWidth) / width;
        float scaleHeight = ((float) height) / height;      

        Matrix matrix = new Matrix();
        matrix.postScale(scaleWidth,scaleHeight);
        Bitmap resizedBitmap = Bitmap.createBitmap(imgHeaderFooter,0,0,width,height,matrix,true);
        BitmapDrawable bmd = new BitmapDrawable(resizedBitmap);

        imageView = new ImageView(this);
        imageView.setScaleType(ScaleType.FIT_XY); 
        imageView.setImageDrawable(bmd);
