先修改SystemUI支持广播接收可以显示或者隐藏系统界面:frameworks/packages/SystemUI/src/com/android/systemui/statusbar/phone/PhoneStatusBar.java

 private BroadcastReceiver mBroadcastReceiver = new BroadcastReceiver() {
        public void onReceive(Context context, Intent intent) {
            ......
            else if (Intent.ACTION_SCREEN_ON.equals(action)) {
                notifyNavigationBarScreenOn(true);
            }
            else if (action.equals("action.HIDE_SYSTEMUI")) {
                setSbNbVisibility(View.GONE);
            }
			else if (action.equals("action.SHOW_SYSTEMUI")) {
                setSbNbVisibility(View.VISIBLE);
            }
        }
    };

    private void setSbNbVisibility(int visibility) {
        Log.d(TAG, "setSbNbVisibility " + visibility);

        if (visibility == View.GONE && mNavigationBarView != null && mStatusBarWindow != null) {
            try {
                mWindowManager.removeViewImmediate(mNavigationBarView);
                mStatusBarWindow.setVisibility(View.GONE);
            } catch (IllegalArgumentException e) {
                Log.w(TAG, "IllegalArgumentException: " + e);
            }
            mNavigationBarView = null;

        } else if (visibility == View.VISIBLE && mNavigationBarView == null && mStatusBarWindow != null) {
            try {
                makeNavigationBarView();
                addNavigationBar();
                mStatusBarWindow.setVisibility(View.VISIBLE);
            } catch (WindowManager.BadTokenException e) {
                // ignore
                Log.w(TAG, "BadTokenException: " + e.getMessage());
            } catch (RuntimeException e) {
                // don't crash if something else bad happens, for example a
                // failure loading resources because we are loading from an app
                // on external storage that has been unmounted.
                Log.w(TAG, "RuntimeException: " + e);
            }
        }
    }

    private void makeNavigationBarView() {
        mNavigationBarView = (NavigationBarView) View.inflate(mContext, R.layout.navigation_bar, null);
        mNavigationBarView.setDisabledFlags(mDisabled1);
        mNavigationBarView.setBar(this);
        mNavigationBarView.setOnVerticalChangedListener(
                new NavigationBarView.OnVerticalChangedListener() {
                    @Override
                    public void onVerticalChanged(boolean isVertical) {
                        if (mAssistManager != null) {
                            mAssistManager.onConfigurationChanged();
                        }
                        mNotificationPanel.setQsScrimEnabled(!isVertical);
                    }
                });
        mNavigationBarView.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                checkUserAutohide(v, event);
                return false;
            }
        });
    }

然后自己应用中发送广播实现显示和隐藏系统界面:

    public static void hideSystemUI(Context context, boolean hide) {
        Intent intent = new Intent();
        intent.setPackage("com.android.systemui");
        if (hide) {
            intent.setAction(ACTION_HIDE_SYSTEMUI);
        } else {
            intent.setAction(ACTION_SHOW_SYSTEMUI);
        }
        context.sendBroadcast(intent);
    }
