android 13MTK平台禁止状态栏下拉

最近在搞android13的项目，之前搞过android11的Systemui禁止下拉，想着应该可以直接移植过去。直到开始着手修改发现11到13的变化还是挺大的，很多类都找不到了。于是又重新研究了下，好了废话不多说。

1.解锁状态下禁止Syatemui下拉

代码路径：\SystemUI\src\com\android\systemui\statusbar\CommandQueue.java

public boolean panelsEnabled() { //KingYan 注释掉现有的返回默认返回false return false; /** KingYan 注释掉以下代码 final int disabled1 = getDisabled1(DEFAULT_DISPLAY); final int disabled2 = getDisabled2(DEFAULT_DISPLAY); return (disabled1 & StatusBarManager.DISABLE_EXPAND) == 0 && (disabled2 & StatusBarManager.DISABLE2_NOTIFICATION_SHADE) == 0 && !ONLY_CORE_APPS;*/ }

2.禁止解锁状态下在Launcher空白区域下拉

代码路径：SystemUI/src/com/android/systemui/recents/OverviewProxyService.java

@Override public void onStatusBarMotionEvent(MotionEvent event) { // KingYan 注释掉以下代码 /* verifyCallerAndClearCallingIdentity("onStatusBarMotionEvent", () -> { mCentralSurfacesOptionalLazy.get().ifPresent(centralSurfaces -> { if (event.getActionMasked() == ACTION_DOWN) { centralSurfaces.getPanelController().startExpandLatencyTracking(); } mHandler.post(() -> { int action = event.getActionMasked(); if (action == ACTION_DOWN) { mInputFocusTransferStarted = true; mInputFocusTransferStartY = event.getY(); mInputFocusTransferStartMillis = event.getEventTime(); centralSurfaces.onInputFocusTransfer( mInputFocusTransferStarted, false *//* cancel *//*, 0 *//* velocity *//*); } if (action == ACTION_UP || action == ACTION_CANCEL) { mInputFocusTransferStarted = false; float velocity = (event.getY() - mInputFocusTransferStartY) / (event.getEventTime() - mInputFocusTransferStartMillis); centralSurfaces.onInputFocusTransfer(mInputFocusTransferStarted, action == ACTION_CANCEL, velocity); } event.recycle(); }); }); });*/ }

3.禁止锁屏页面从中间位置（时间位置）下拉

4.禁止锁屏页面状态栏下拉
