android 用沉浸式隐藏status bar

沉浸式，隐藏status bar：

adb shell settings put global policy_control immersive.status=*

隐藏navigation bar:

adb shell settings put global policy_control immersive.navigation=*

禁止statusbar 下拉：

disable statusbar expand

StatusBarManager.java (core\java\android\app):    public void disable(int what) {        try {            final IStatusBarService svc = getService();            if (svc != null) {                //<20180728-bacalli,disable statusbar expand                //svc.disable(what, mToken, mContext.getPackageName());                mService.disable(DISABLE_EXPAND, mToken, mContext.getPackageName());                //>20180728-bacalli, end            }        } catch (RemoteException ex) {            throw ex.rethrowFromSystemServer();        }    }

禁止点击在最上面时显示statusbar：

//PhoneWindowManager.java       // monitor for system gestures        mSystemGestures = new SystemGesturesPointerEventListener(context,                new SystemGesturesPointerEventListener.Callbacks() {                    @Override                    public void onSwipeFromTop() {                        //lightin.kunlin, no need to show statusbar for AR project, start                        /*                        if (mStatusBar != null) {                            requestTransientBars(mStatusBar);                        }                        */                        //lightin.kunlin, end                     }                    @Override                    public void onMouseHoverAtTop() {                        //lightin.kunlin, no need to show status bar for AR project. start                        /*                        mHandler.removeMessages(MSG_REQUEST_TRANSIENT_BARS);                        Message msg = mHandler.obtainMessage(MSG_REQUEST_TRANSIENT_BARS);                        msg.arg1 = MSG_REQUEST_TRANSIENT_BARS_ARG_STATUS;                        mHandler.sendMessageDelayed(msg, 500);                        */                        //lightin.kunlin. end                    }

禁止显示navigation bar：

可以用config_showNavigationBar 控制navigationbar的显示

/frameworks/base/core/res/res/values/config.xml         true/frameworks/base/services/core/java/com/android/server/policy/PhoneWindowManager.java        mHasNavigationBar = res.getBoolean(com.android.internal.R.bool.config_showNavigationBar);        // Allow a system property to override this. Used by the emulator.        // See also hasNavigationBar().        String navBarOverride = SystemProperties.get("qemu.hw.mainkeys");        if ("1".equals(navBarOverride)) {            mHasNavigationBar = false;        } else if ("0".equals(navBarOverride)) {            mHasNavigationBar = true;        }    private boolean canHideNavigationBar() {        return mHasNavigationBar;    }
