set Bitmap as size of image View

Question

i'have Get Bitmap from oneActivity to secondSctivity in imageview. Now i want this bitmap as the same size of Imageview. but this code is now working.

    ViewTreeObserver vto = ph.getViewTreeObserver(); 
    vto.addOnPreDrawListener(new ViewTreeObserver.OnPreDrawListener() {
        public boolean onPreDraw() {
            ph.getViewTreeObserver().removeOnPreDrawListener(this); 
            ph.getMeasuredWidth();
            ph.getMeasuredHeight(); 
            return true;
            } 
        });


    // set contact Photo Bitmap in Image view-------------------------------------------------

    byte[] byteArray = getIntent().getByteArrayExtra("image");
    if (byteArray != null) {
        bmp = BitmapFactory.decodeByteArray(byteArray, 0, byteArray.length);
    }

    if (bmp != null) {
        Bitmap bmpimg = Bitmap.createScaledBitmap(bmp,ph.getMeasuredWidth(),ph.getMeasuredHeight() , true);
        ph.setImageBitmap(createRoundedBitmap(bmpimg,5));



    } else {
        ph.setImageResource(R.drawable.upload_photo);
    }

what i have to do for that???

First you find your Imageview width and height then scaled your bitmap that width and height. — Divyang Metaliya, Jul 23 '14 at 04:50
ભાઈ કયો ને Imageview ની Height અને width કેવી રીતે સેટ કરું — user3855491, Jul 23 '14 at 05:15
Bitmap bmpimg = Bitmap.createScaledBitmap(bmp,ph.getMeasuredWidth(), ph.getMeasuredWidth(), true);....... this is not work — user3855491, Jul 23 '14 at 05:34
You want the imageview to match your bitmap size or vice versa? — hypd09, Jul 23 '14 at 05:54

will you can get ImageView size by imageViewObject.getWidth(); and obj.getHeight(); then scaled your bitmap following those value not tested.

Bitmap bmpimg = Bitmap.createScaledBitmap(bmp, obj.getWidth(), getHeight(), true);

i hope this helps.

i have found this from http://stackoverflow.com/questions/10411975/how-to-get-the-width-and-height-of-an-image-view-in-android# – user3855491 Jul 23 '14 at 05:12
@user3855491 yes that getViewTreeObserver code is work and you can get width and Height from that. – Divyang Metaliya Jul 23 '14 at 05:27
you only need ImageView Height and Width, right, so you can't call getWidth() and getHeight() on ImageView from onCreate() in activity you have to wait for activity attached to window and then call getWidth() and getHeight(). just call getWidth() and getHeight() from anywhere else onCreate(). – NoXSaeeD Jul 23 '14 at 05:38

Here is the very simple and easy solution am sure it will work for you Use "scaleType" property of ImageView in your xml file keep it as "scaleType=fitXY" here is snippest

 <ImageView
            android:id="@+id/img1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:scaleType="fitXY"/>

Enjoy coding

but brother my imageview size change as par mobile device. but bitmap is fix. so how can i adjust that?? – user3855491 Jul 23 '14 at 06:30
ok then you can set image view size in XML for all mobile and in java file you can calculate height and width of imageview progrmatically then set this height and width to bitmap during its formation and then set that bitmap to image view – Android is everything for me Jul 23 '14 at 06:35
