Main Idea to set param android:fitsSystemWindows="true" for set image background content under the status bar layer. And make status bar transparent. So that only image background will be visisble.
Has some issue. In case with CollapsingToolbarLayout adjust resize flag not working when show Soft KeyBoard. But always work with adjustPan instaed adjustResize
problem , about fitsSystemWindows , external library for transparent status bar
