Android13-Launcher3_屏蔽长按屏幕弹出弹窗

未去掉前

Launcher3/src/com/android/launcher3/Workspace.java

在构造方法注册触摸事件

    public Workspace(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);

        mLauncher = Launcher.getLauncher(context);
        mStateTransitionAnimation = new WorkspaceStateTransitionAnimation(mLauncher, this);
        mWallpaperManager = WallpaperManager.getInstance(context);
        mAllAppsIconSize = mLauncher.getDeviceProfile().allAppsIconSizePx;
        mWallpaperOffset = new WallpaperOffsetInterpolator(this);

        setHapticFeedbackEnabled(false);
        initWorkspace();

        // Disable multitouch across the workspace/all apps/customize tray
        setMotionEventSplittingEnabled(true);
        setOnTouchListener(new WorkspaceTouchListener(mLauncher, this));
        mStatsLogManager = StatsLogManager.newInstance(context);
    }

Launcher3/src/com/android/launcher3/touch/WorkspaceTouchListener.java

WorkspaceTouchListener继承自GestureDetector.SimpleOnGestureListener，有长按事件

    @Override
    public void onLongPress(MotionEvent event) {
        maybeShowMenu();
    }

    private void maybeShowMenu() {
        if (mLongPressState == STATE_REQUESTED) {
            TestLogging.recordEvent(TestProtocol.SEQUENCE_MAIN, "Workspace.longPress");
            if (canHandleLongPress()) {
                mLongPressState = STATE_PENDING_PARENT_INFORM;
                mWorkspace.getParent().requestDisallowInterceptTouchEvent(true);

                mWorkspace.performHapticFeedback(HapticFeedbackConstants.LONG_PRESS,
                        HapticFeedbackConstants.FLAG_IGNORE_VIEW_SETTING);
                mLauncher.getStatsLogManager().logger().log(LAUNCHER_WORKSPACE_LONGPRESS);
                //这里显示弹窗，注释掉
                mLauncher.showDefaultOptions(mTouchDownPoint.x, mTouchDownPoint.y);
            } else {
                cancelLongPress();
            }
        }
    }

注释掉后，长按不显示
