Android 13接大屏时底下显示任务栏以及虚拟按键靠右问题
Android 13大屏显示时，界面底下显示任务栏，返回、home，recent按键显示会靠右。和Android12类似，但跟以往的Android系统不一样。之前Android12上面修改过这个显示：

但是，Android13上面又不一样了。
Android12上面修改Luacher3里面的ENABLE_TASKBAR 值就可以去掉任务栏的显示，但是Android13上面没有ENABLE_TASKBAR这个属性。于是，找了一下ENABLE_TASKBAR在Android12上面调用的地方packages\apps\Launcher3\quickstep\src\com\android\launcher3\taskbar\TaskbarManager.java中recreateTaskbar()函数里面：
private void recreateTaskbar() { destroyExistingTaskbar(); DeviceProfile dp = mUserUnlocked ? LauncherAppState.getIDP(mContext).getDeviceProfile(mContext) : null; boolean isTaskBarEnabled = FeatureFlags.ENABLE_TASKBAR.get() && dp != null && dp.isTaskbarPresent; if (!isTaskBarEnabled) { SystemUiProxy.INSTANCE.get(mContext) .notifyTaskbarStatus(/* visible */ false, /* stashed */ false); return; }
然后，在Android13上面的Launcher3找了一下recreateTaskbar()，还是存在的，内容如下：
-
@VisibleForTesting public void recreateTaskbar() { DeviceProfile dp = mUserUnlocked ? LauncherAppState.getIDP(mContext).getDeviceProfile(mContext) : null; destroyExistingTaskbar(); boolean isTaskBarEnabled = dp != null && isTaskbarPresent(dp); if (!isTaskBarEnabled) { SystemUiProxy.INSTANCE.get(mContext) .notifyTaskbarStatus(/* visible */ false, /* stashed */ false); return; } if (mTaskbarActivityContext == null) { mTaskbarActivityContext = new TaskbarActivityContext(mContext, dp, mNavButtonController, mUnfoldProgressProvider); } else { mTaskbarActivityContext.updateDeviceProfile(dp, mNavMode); } mTaskbarActivityContext.init(mSharedState); if (mActivity != null) { mTaskbarActivityContext.setUIController( createTaskbarUIControllerForActivity(mActivity)); } }
发现都有一个控制任务栏显示的参数boolean isTaskBarEnabled，这个参数在由 isTaskbarPresent(dp)决定，这个函数实现如下：
-
private boolean isTaskbarPresent(DeviceProfile deviceProfile) { return FLAG_HIDE_NAVBAR_WINDOW || deviceProfile.isTaskbarPresent; }
上面函数中的返回值由packages\apps\Launcher3\src\com\android\launcher3\DeviceProfile.java中的isTaskbarPresent决定。isTaskbarPresent值又是packages\apps\Launcher3\src\com\android\launcher3\util\DisplayController.java中的isTablet函数决定。
-
DeviceProfile(Context context, InvariantDeviceProfile inv, Info info, WindowBounds windowBounds, SparseArray<DotRenderer> dotRendererCache, boolean isMultiWindowMode, boolean transposeLayoutWithOrientation, boolean isMultiDisplay, boolean isGestureMode, @NonNull final ViewScaleProvider viewScaleProvider) { this.inv = inv; this.isLandscape = windowBounds.isLandscape(); this.isMultiWindowMode = isMultiWindowMode; this.transposeLayoutWithOrientation = transposeLayoutWithOrientation; this.isMultiDisplay = isMultiDisplay; this.isGestureMode = isGestureMode; windowX = windowBounds.bounds.left; windowY = windowBounds.bounds.top; this.rotationHint = windowBounds.rotationHint; mInsets.set(windowBounds.insets); isScalableGrid = inv.isScalable && !isVerticalBarLayout() && !isMultiWindowMode; // Determine device posture. mInfo = info; isTablet = info.isTablet(windowBounds); isPhone = !isTablet; isTwoPanels = isTablet && isMultiDisplay; isTaskbarPresent = isTablet && ApiWrapper.TASKBAR_DRAWN_IN_PROCESS;
isTablet函数实现如下：
-
public boolean isTablet(WindowBounds bounds) { return smallestSizeDp(bounds) >= MIN_TABLET_WIDTH; }
MIN_TABLET_WIDTH值为600，上面的意思是最小边dp值大于600就返回true，判断为平板设备。
要让taskbar任务栏不显示，把所有判断该值的地方，都改成返回false。
