1.导航栏与状态栏

首先看一下导航栏和状态栏位置:

最上面是状态栏statusBar

最下面是导航栏`NavagationBar

一、隐藏导航栏

目录:

frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/phone/PhoneStatusBar.java

注释掉内容:

// For small-screen devices (read: phones) that lack hardware navigation buttonsprotected void addNavigationBar() {if (DEBUG) Log.v(TAG, "addNavigationBar: about to add " + mNavigationBarView);if (mNavigationBarView == null) return;prepareNavigationBarView();//mWindowManager.addView(mNavigationBarView, getNavigationBarLayoutParams());}
