Examples with OnApplyWindowInsetsListener androidx.core.view.OnApplyWindowInsetsListener used on opensource projects

Example 1 with OnApplyWindowInsetsListener

use of androidx.core.view.OnApplyWindowInsetsListener in project StatusBarCompat by niorgai.

the class StatusBarCompatLollipop method setStatusBarColorForCollapsingToolbar.

/**
 * compat for CollapsingToolbarLayout
 *
 * 1. change to full-screen mode(like translucentStatusBar).
 * 2. cancel CollapsingToolbarLayout's WindowInsets, let it layout as normal(now setStatusBarScrimColor is useless).
 * 3. set View's FitsSystemWindow to false.
 * 4. add Toolbar's height, let it layout from top, then add paddingTop to layout normal.
 * 5. change statusBarColor by AppBarLayout's offset.
 * 6. add Listener to change statusBarColor
