去除 Launcher3 底部类似 dockbar 条目

packages/apps/Launcher3/src/com/android/launcher3/DeviceProfile.java

         availableHeightPx = windowBounds.availableSize.y;mInfo = info;
-        isTablet = info.isTablet(windowBounds);
+        //isTablet = info.isTablet(windowBounds);
+       isTablet = false;//cczheng changeisPhone = !isTablet;isTwoPanels = isTablet && useTwoPanels;

去除 Launcher3 在 workspace 中下滑手势展开状态栏功能
解决即使在 SystemUI 中将 statusBar 隐藏了，workspace 中下拉也能显示

packages/apps/Launcher3/quickstep/src/com/android/launcher3/uioverrides/QuickstepLauncher.java

        if (!getDeviceProfile().isMultiWindowMode) {// android.util.Log.d("ccz","StatusBarTouchController");// list.add(new StatusBarTouchController(this));//cczheng remove launcher pull down statusbar notification}list.add(new LauncherTaskViewController(this));return list.toArray(new TouchController[list.size()]);}
