Android - Choose an image from gallery and then resize it to fit into ImageView - android-imageview

Question

I'm trying to fit an image into ImageView maintaining the aspect ratio, it loads the image but I don't know how to resize it well. If the image it's too big I want to crop it and if it's small I want to fit the ImageView, my code so far it this:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
try {
// When an Image is picked
if (requestCode == RESULT_LOAD_IMG && resultCode == RESULT_OK
&& null != data) {
// Get the Image from data
Uri selectedImage = data.getData();
String[] filePathColumn = {MediaStore.Images.Media.DATA};
// Get the cursor
Cursor cursor = getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
// Move to first row
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
imgDecodableString = cursor.getString(columnIndex);
cursor.close();
ImageView imgView = (ImageView) findViewById(R.id.imageButtonFotoPerfil);
// Set the Image in ImageView after decoding the String
imgView.setImageBitmap(BitmapFactory
.decodeFile(imgDecodableString));
} else {
Toast.makeText(this, "You haven't picked Image",
Toast.LENGTH_LONG).show();
}
} catch (Exception e) {
Toast.makeText(this, "Something went wrong", Toast.LENGTH_LONG)
.show();
}
}
and the XML for the imageView:
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/imageButtonFotoPerfil"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginBottom="15dp"
android:onClick="loadImagefromGallery"
android:src="#drawable/perfil_persona_b"
android:background="#null"/>

Change layout_width, hegiht to 100dp, 120dp what size do you want or you can calculate size of image depend on size of screen.
