Skip transparent background in an image when setting an image as background in android

I am working on a project in which I am using a lot of images. My friend has designed all the images in photoshop and all those images are of my required size.
But the problem is that when my friend exported those images from the photoshop, he exported those images with a transparent background and that transparent background with the image makes the frame size bigger than required. And when I set that image to some ImageView, it expands to the whole screen due to its bigger frame size.
Now my question is that Is there a way to set image in imageview so that the transparent part is automatically ignored and the image of my required size just sets into the imageview. Or It is required to crop those images in photoshop and then use those images.
I am sorry if someone couldn't understand the question but I can elaborate if asked.

The way I would do it would be just edit them in photoshop, but I found another way if you want to look into it. Its called webP and you can check it out here. With this you can skip the transparency, but I think the size would stay the same, You can try it out if you want though.
Hope this helps!

How to fill svg shape when i touch on svg image without loss quality of svg

This image is SVG image which is loaded into SVGImageView. I can't fill color into SVG with onTouch listener. I am tired to fill color into particular shape or area. Help me. Thank you.

And fill area with different color like this :

AFAIK at the moment none of the SVG libraries for Android support interaction. I am the author of AndroidSVG and it is a high priority on my list of things to implement.
If you need it now, however, I think you will need to resort to displaying the SVG in a WebView and using Javascript events to determine what is clicked on.

Google Photos App style Image Cropping, Straightening and panning

I am looking for Google Photos app style image manipulation. I am kind of new to image processing. Any leads on how to make the cropping rectangle with the image the same size as cropping rectangle, rotation (which rotates both the image and cropping rectangle), image straightening (including how to get that angle slider kind of UI) will be great. If there are some libraries that has these features, that will also work.

Square has a library for loading and playing with images.
Here are some features:
- Handling ImageView recycling and download cancelation in an adapter.
- Complex image transformations with minimal memory use.
- Automatic memory and disk caching.
There is detailed information on how to use the lib on their website. Check it out: Picasso
The gradle line you need to add is:
compile 'com.squareup.picasso:picasso:2.5.2'
It's very easy to use. Here is how I load and adjust an image into an ImageView in my example app:
Picasso.with(mContext).load("http://cdn0.vox-cdn.com/uploads/chorus_asset/file/798874/DSCF1913.0.jpg").fit().centerCrop().into(imageView);
As you can see, I've used fit().centerCrop() here. This will adjust the image to fit proportionally inside my imageView. You can try different forms of image transformations to better fit your needs.
You can also load images from your drawable folder or directly from file:
Picasso.with(context).load(R.drawable.landing_screen).into(imageView1);
Picasso.with(context).load("file:///android_asset/DvpvklR.png").into(imageView2);
Picasso.with(context).load(new File(...)).into(imageView3);
EDIT:
Looks like I didn't fully understand your question when I first read it. Here are some tips for what you're trying to achieve. May not be exactly what you want, but I think it might be a start.
If you want to rotate your image, you can do it with Picasso using RequestCreator.rotate(float degrees).
Here's the documentation for RequestCreator.
As for cropping images (inside a specified rectangle, as you've shown), there is:
Android crop.
Or you can use Picasso Transformations and create a transformation like
CropTransformation(Top, Center, Bottom);
And ask Picasso to transform the image like this:
Picasso.with(mContext).load(R.drawable.demo)
.transform(transformation).into((ImageView) findViewById(R.id.image));
Also, as #Amit K Saha said on his answer, you can use some Android SDK effects. Check android.media.effect.
Hope this helps.

There are some help from android sdk. May not be exactly what you are looking but worth of a shot to start. Have a look here.
android.media.effect
And list of available effects can be found here

How to make glow effect in image view for a small part

I want to make a small part of the image glow whenever the activity is loaded. Do I need to take the exact coordinates of the image part?

I recommend using a GIF. It can be loaded as an image and won't require any changes in your code. A smallish tutorial can be found in this Youtube video.

How do I load a blurred image first, in imageview, and then make it sharp, in order to enhance user experience, for android?

I'm working on an application in which I need to download lots of images. The images are to be seen in the fullscreen mode. Therefore, I wanted to know how to load an image, speedily, to make the application more responsive and enhance user experience. I would like to, atleast, show a blurred image first and than make it sharp. Thanks.

use BitmapFactory.Options.inSamleSize to load a downsampled version of the image. Then load the bigger image and do a fade transition using a TransitionDrawable

You're looking for "progressive image rendering", which can be done in a variety of different image formats, including png, jpeg, gif, etc. The next time you're going to save an image in a good graphics program, select one of those formats and take a look at your save options. You should have an option to save an "interlaced" image.
