理性去除导航栏 NavigationBar
说明
// SystemUI/src/com/android/systemui/statusbar/phone/PhoneStatusBar.java
boolean showNav = mWindowManagerService.hasNavigationBar();
if (DEBUG) Log.v(TAG, "hasNavigationBar=" + showNav);
if (showNav) {
mNavigationBarView =
(NavigationBarView) View.inflate(context, R.layout.navigation_bar, null);
....
}
// services/core/java/com/android/server/wm/WindowManagerService.java
mWindowManagerService.hasNavigationBar()
mPolicy.hasNavigationBar();
// services/core/java/com/android/server/policy/PhoneWindowManager.java
mHasNavigationBar = res.getBoolean(com.android.internal.R.bool.config_showNavigationBar);
由此可见, 系统资源配置项里面原本, 提供了 NavigationBar 可视化选项. 所以修改 R.bool.config_showNavigationBar 即可实现
