I am beginner at android development. I was recently looking at some one else code and fond some functions
view.onApplyWindowInsets(windowInsets), windowInsets.getSystemWindowInsetTop(). And this word was used again and again in the same app.
I tried googling it and found
InsetDrwable class with explanation
A Drawable that insets another Drawable by a specified distance. This is used when a View needs a background that is smaller than the View’s actual bounds.
Can some one explain me what is the meaning on
Insets and what those piece of code up there meant?
A explanation with an example will be appreciated.
Suppose you have a TextView and you need to add a background to the TextView. But, on the other hand, you don’t want the background to scan the entire View (TextView), therefore, you need to use Insets.
The background can be a Drawable. Hence you need to use the
<inset> attribute inside your xml file (activity_main.xml) “For Example”.
Then, after using the
<inset> tag, you can specify some attributes such as:
<inset android:drawable="@drawable/(Enter the file name under drawable)" android:insetBottom="4dp" android:insetTop="4dp"/>
For more information please have a look at InsetDrawable on Android developer.com
Hope this helps!
