java - Android - Assigning Bitmap to ImageView changes size -


my application takes photo camera of smartphone. after capturing photo want assign photo imageview. size of imageview changes. 

protected void onactivityresult(int requestcode, int resultcode, intent data) { if (requestcode == capture_image_activity_request_code     && resultcode == activity.result_ok) {    contentresolver cr = getcontentresolver();   bitmap bitmap = null;   bitmap scaledbitmap  = null;   inputstream in = null;   image image = this.getactualimage();          try {     in = cr.openinputstream(this.imageuri);     bitmapfactory.options o = new bitmapfactory.options();     o.insamplesize = 1;     bitmap = bitmapfactory.decodestream(in, null, o);      imageview view = null;     view = (imageview) findviewbyid(r.id.img_face1);                        int height = view.getheight();     int width = view.getwidth();     log.i(tag, "scale operation dimenions - width: " + width         + ", height: " + height);      scaledbitmap = bitmap.createscaledbitmap(bitmap, width, height, true);     view.setimagebitmap(scaledbitmap);     system.gc();     in.close();   } catch (exception e) {     log.e("camera", e.tostring());   }

my layout xml looks follows:

    <linearlayout     xmlns:android="http://schemas.android.com/apk/res/android"     android:id="@+id/screen_capture_face2"     style="@style/linearlayoutvertical"     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:weightsum="2" >      <imageview         android:id="@+id/img_face1"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_weight="1"         android:adjustviewbounds="true"         android:contentdescription="@string/desc_dummy_face"         android:src="@drawable/dummy_face"          />      <imageview         android:id="@+id/img_face2"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_weight="1"         android:adjustviewbounds="true"         android:contentdescription="@string/desc_dummy_face"         android:src="@drawable/dummy_face"          />  </linearlayout>

after assign bitmap imageview img_face1 size changes. why happen? missing? new android , maybe little mistake.

thanks bye

first of all, setting adjustviewbounds true. reference says:

set true if want imageview adjust bounds preserve aspect ratio of drawable.

you try removing it, , additionally add scaletype="fitcenter" option image resized instead of image view. want change wrap_content values layout attributes, make view big enough show entire content.
