【Android】【虛拟欄】判斷手機是否有虛拟欄

首先判斷手機是否有虛拟欄，我這邊隻是做了很簡單的判斷，判斷手機是否有回退和Home鍵

//是否有下方虛拟欄
private static boolean isNavigationBarAvailable() {
    boolean hasBackKey = KeyCharacterMap.deviceHasKey(KeyEvent.KEYCODE_BACK);
    boolean hasHomeKey = KeyCharacterMap.deviceHasKey(KeyEvent.KEYCODE_HOME);
    return (!(hasBackKey && hasHomeKey));
}      

擷取下方虛拟欄高度  

public static int getNavigationBarHeight() {
    if (isNavigationBarAvailable()) {
        Resources resources = ApplicationLoader.context.getResources();
        int resourceId = resources.getIdentifier("navigation_bar_height", "dimen", "android");
        if (resourceId > 0) {
            return resources.getDimensionPixelSize(resourceId);
        }
    }
    return 0;
}
