How to replace drawable image with all screen size image using android studio?

Issue

In my code I have many icons which are used in application. Now I want to change all icons with all its sizes like hdpi, xhdpi ect.

How to change all sizes of icons in a shortcut way? Please suggest me.

Solution

You can use this library to make things easier for you to manipulate drawable in different screen sizes.
Here is the Library

You can put the height and width in SDP it will manage itself for all screens

For example like this

<ImageView
    android:id="@+id/ivImage"
    android:layout_width="@dimen/_9sdp"
    android:layout_height="@dimen/_18sdp"
    android:layout_alignParentEnd="true"
    android:layout_alignParentRight="true"
    android:layout_centerVertical="true"
    android:src="@drawable/icon" />

OR

Using this code you can get runtime Display's Width & Height

DisplayMetrics displayMetrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);
int height = displayMetrics.heightPixels;
int width = displayMetrics.widthPixels;

In a view you need to do something like this:

((Activity) getContext()).getWindowManager()
                         .getDefaultDisplay()
                         .getMetrics(displayMetrics);

You can get the screen sizes and manage itself.
