Android ImageView Fixing Image Size

Question

I have an Android Application, where I have an ImageView, I need to keep the size constant, there can be various images that I need to put into this ImageView, of different sizes.

I just need to ensure that all the Images must fit into the ImageView, the Image should increase in size if it is smaller and should decrease, in case it is bigger.

Thanks a lot for your time.

Post the code with what have you tried. – Praveenkumar Aug 21 '12 at 06:50 — Praveenkumar, Aug 21 '12 at 06:50

In your case you need to

Fix the ImageView's size. You need to use dp unit so that it will look the same in all devices.
Set android:scaleType to fitXY

Below is an example:

<ImageView
    android:id="@+id/photo"
    android:layout_width="200dp"
    android:layout_height="100dp"
    android:src="@drawable/iclauncher" 
    android:scaleType="fitXY"/>

For more information regarding ImageView scaleType please refer to the developer website.

Why `fitXY`? and why not using `minHeight` and `minWidth` instead of layout_x ? – Yousha Aleayoub Sep 13 '16 at 22:49
I had everything fitting in the XML Layout, and setImageResource broke the scaling even when the replacement was identical in size. Adding scaleType="fitXY" fixed it perfectly! – Dave Hubbard Jan 23 '19 at 21:25
What worked for me is scaleType="fitCenter", to ensure the image x/y ratio is kept. – Lech Migdal Aug 18 '19 at 06:32

Try this

ImageView img
    Bitmap bmp;
    int width=100;
    int height=100;
    img=(ImageView)findViewById(R.id.imgView);
    bmp=BitmapFactory.decodeResource(getResources(),R.drawable.image);//image is your image                                                            
    bmp=Bitmap.createScaledBitmap(bmp, width,height, true);
    img.setImageBitmap(bmp);

Or If you want to load complete image size in memory then you can use

<ImageView
    android:id="@+id/img"
    android:layout_width="100dp"
    android:layout_height="100dp"
    android:src="@drawable/image" 
    android:scaleType="fitXY"/>

You can also try this, suppose if you want to make a back image button and you have "500x500 png" and want it to fit in small button size.

Use dp to fix ImageView's size.

add this line of code to your Imageview.

android:scaleType="fitXY"

EXAMPLE:

<ImageView
        android:layout_width="50dp"
        android:layout_height="50dp"
        android:id="@+id/imageView2"
        android:src="@drawable/Backicon"
        android:scaleType="fitXY"
        />

I had the same issue and this helped me.

<ImageView
    android:id="@+id/image"
    android:layout_width="100dp"
    android:layout_height="100dp"
    android:scaleType="fitXY"
    />

You need to add android:scaleType and set fitXY in XML unless you add layout_width & layout_height attributes.
Example:
android:scaleType="fitXY"

If you want to add programmatically,
Example:
youriv.setScaleType(ImageView.ScaleType.FIT_XY);

There is not a clear answer yet. ImageView is not resizing to image size every image loads.
