5. HIDE NavigationBar and StatusBar
6. public static void hideSystemUi(Window window) { int options = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_FULLSCREEN | View.SYSTEM_UI_FLAG_LAYOUT_STABLE; if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) { options = options ^ View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY; } else { options = options | View.SYSTEM_UI_FLAG_LAYOUT_STABLE; } window.getDecorView().setSystemUiVisibility(options); }
7. SHOW NavigationBar and StatusBar
8. public static void showSystemUi(Window window) { window.getDecorView() .setSystemUiVisibility( View.SYSTEM_UI_FLAG_LAYOUT_STABLE | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN); }
9. showSystemUi & hideSystemUi actual expected
10. showSystemUi & hideSystemUi actual expected
11. 1. Refrection
12. Reflection <!-- Height of the status bar --> <dimen name="status_bar_height">24dp</dimen> <!-- Height of the bottom navigation / system bar. --> <dimen name=“navigation_bar_height">48dp</dimen> <!-- Height of the bottom navigation bar in portrait; often the same as @dimen/navigation_bar_height --> <dimen name=“navigation_bar_height_landscape">48dp</dimen> <!-- Width of the navigation bar when it is placed vertically on the screen --> <dimen name="navigation_bar_width">42dp</dimen>
13. Reflection // portrait resources.getIdentifier("navigation_bar_height", "dimen", “android"); // landscape resources.getIdentifier("navigation_bar_height_l andscape", "dimen", "android");
14. But … • Some device with hardware keyboard return wrong size • tablet? mobile??
15. 2. Calculate
16. Calculate StatusBar and NavigationBar Size • getSize • getCurrentSizeRange • getRealSize(getRawSize)
17. getRealSize getSize getCurrentSizeRange
18. getRealSize getSize getCurrentSizeRange
19. NavigationBar Width public int getNavigationBarWidth() { return getRealSize().x - getDisplaySize().x; }
20. NavigationBar Height public int getNavigationBarHeight() {
 return getRealSize().y - getDisplaySize().y;
 }
21. StatusBar Height public int getStatusBarHeight() { Point smallSize = new Point(); Point largeSize = new Point(); display.getCurrentSizeRange(smallSize, largeSize); // getDisplaySize() means getSize() Point displaySize = getDisplaySize(); if (displaySize.x > displaySize.y) { return displaySize.y - smallSize.y; } else { return displaySize.y - largeSize.y; } }
22. 3. WindowInsetsCompat
23. private class ApplyInsetsListener implements android.support.v4.view.OnApplyWindowInsetsListener { @Override public WindowInsetsCompat onApplyWindowInsets(View v, WindowInsetsCompat insets) { if (mLastInsets != insets) { mLastInsets = insets; } return insets; } }
24. ViewCompat.setOnApplyWindowInsetsListener(view, new ApplyInsetsListener());
25. public int getNavigationBarWidth() { return mLastInsets == null ? 0 : mLastInsets.getSystemWindowInsetRight(); } public int getNavigationBarHeight() { return mLastInsets == null ? 0 : mLastInsets.getSystemWindowInsetBottom(); } public int getStatusBarHeight() { return mLastInsets == null ? 0 : mLastInsets.getSystemWindowInsetTop(); }
26. Thank you for your attention.
