Android/UIの判定 (setInitialDisplaySize?)

↑

Android 4.4 

  • // SystemUI (status bar) layout policy
int shortSizeDp = shortSize * DisplayMetrics.DENSITY_DEFAULT / density;
int longSizeDp = longSize * DisplayMetrics.DENSITY_DEFAULT / density;

// Allow the navigation bar to move on small devices (phones).
mNavigationBarCanMove = shortSizeDp < 600;
↑

Android 4.3 

  • // SystemUI (status bar) layout policy
int shortSizeDp = shortSize * DisplayMetrics.DENSITY_DEFAULT / density;

if (shortSizeDp < 600) {
    // 0-599dp: "phone" UI with a separate status & navigation bar
    mHasSystemNavBar = false;
    mNavigationBarCanMove = true;
} else if (shortSizeDp < 720) {
    // 600+dp: "phone" UI with modifications for larger screens
    mHasSystemNavBar = false;
    mNavigationBarCanMove = false;
}
↑

Android 4.2 

  • int shortSizeDp = shortSize * DisplayMetrics.DENSITY_DEFAULT / density;

if (shortSizeDp < 600) {
    // 0-599dp: "phone" UI with a separate status & navigation bar
    mHasSystemNavBar = false;
    mNavigationBarCanMove = true;
} else if (shortSizeDp < 720) {
    // 600+dp: "phone" UI with modifications for larger screens
    mHasSystemNavBar = false;
    mNavigationBarCanMove = false;
}

Android 4.1 

  • int shortSizeDp = shortSize
        * DisplayMetrics.DENSITY_DEFAULT
        / DisplayMetrics.DENSITY_DEVICE;

if (shortSizeDp < 600) {
    // 0-599dp: "phone" UI with a separate status & navigation bar
    mHasSystemNavBar = false;
    mNavigationBarCanMove = true;
} else if (shortSizeDp < 720) {
    // 600-719dp: "phone" UI with modifications for larger screens
    mHasSystemNavBar = false;
    mNavigationBarCanMove = false;
} else {
    // 720dp: "tablet" UI with a single combined status & navigation bar
    mHasSystemNavBar = true;
    mNavigationBarCanMove = false;
}
↑

Android 4.0.4 

  • // Determine whether the status bar can hide based on the size
// of the screen.  We assume sizes > 600dp are tablets where we
// will use the system bar.
int shortSizeDp = shortSize
        * DisplayMetrics.DENSITY_DEFAULT
        / DisplayMetrics.DENSITY_DEVICE;
mStatusBarCanHide = shortSizeDp < 600;

メモ

  • mNavigationBarCanMove? - 横画面にした時にナビゲーションバーを移動するかどうか
