如何将左侧导航栏放在状态栏后面？ - SystemUI - Android - AOSP

Question

我使用Android AOSP Project中的TYPE_NAVIGATION_BAR_PANEL将底部导航栏定制到左侧导航栏。但问题是它与状态栏重叠。需要将导航栏放在状态栏后面。

Answer 1

我认为这是有目的的。 StatusBar具有比导航类型更低的图层类型。这意味着导航视图位于StatusBar的前面。

/**
 * Window type: the status bar.  There can be only one status bar
 * window; it is placed at the top of the screen, and all other
 * windows are shifted down so they are below it.
 * In multiuser systems shows on all users' windows.
 */
public static final int TYPE_STATUS_BAR         = FIRST_SYSTEM_WINDOW;
.....
/**
 * Window type: Navigation bar (when distinct from status bar)
 * In multiuser systems shows on all users' windows.
 * @hide
 */
public static final int TYPE_NAVIGATION_BAR = FIRST_SYSTEM_WINDOW+19;

作为一个四处走动，您可以修改导航栏的布局参数。您可以将y设置为getStatusBarHeight()，将重力设置为Gravity.BOTTOM - 从未测试过。
