I'm showing images from gallery to Imageview.
I'm using below code
Bitmap background = Bitmap.createBitmap((int) width, (int) height, Bitmap.Config.ARGB_8888);
float originalWidth = bMap.getWidth(), originalHeight = bMap.getHeight();
Canvas canvas = new Canvas(background);
float scale = width/originalWidth;
float xTranslation = 0.0f, yTranslation = (height - originalHeight * scale)/2.0f;
Matrix transformation = new Matrix();
transformation.postTranslate(xTranslation, yTranslation);
transformation.preScale(scale, scale);
Paint paint = new Paint();
paint.setFilterBitmap(true);
canvas.drawBitmap(bMap, transformation, paint);
imageView1.setImageBitmap(background);
Case 1: working.
Case 2: not working
in case 2 why image is not getting scaled properly, to fill the imageview? Please let me know where I'm going wrong.
Android already provides a method to create scaled bitmap. check this out LINK
Are you wanting it to stretch? Use fitxy.
Use the scaleType
attribute on your ImageView in your layout xml file.
Example:
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scaleType="centerCrop" />
Then you can set your image on the ImageView
using setImageUri(Uri uri)
(I assume you have the Uri of the image to show).
