Percentage of screen in android

Posted on by

For doing percentage of screen in android, we use PercentRelativeLayout:

Subclass of RelativeLayout that supports percentage based dimensions and margins. You can specify dimension or a margin of child by using attributes with “Percent” suffix.

The attributes that you can use are:

  • layout_widthPercent
  • layout_heightPercent
  • layout_marginPercent
  • layout_marginLeftPercent
  • layout_marginTopPercent
  • layout_marginRightPercent
  • layout_marginBottomPercent
  • layout_marginStartPercent
  • layout_marginEndPercent
  • layout_aspectRatio

In our dependencies

compile 'com.android.support:percent:22.2.0'

Follow this example:
