2.Launcher3 去掉Hotseat的核心类
packages/apps/Launcher3/res/layout/launcher.xml
packages/apps/Launcher3/src/com/android/launcher3/DeviceProfile.java3.Launcher3 去掉Hotseat的核心功能分析和实现 在Launcher3中主页面就是launcher.xml只布局hotseat布局也在这里面所以隐藏hotseat可以从这里先看launcher.xml的布局。 首先看下launcher.xml的布局
3.1 launcher.xml hotseat布局
com.android.launcher3.LauncherRootView

hotseatBarSizePx 0/*ResourceUtils.pxFromDp(inv.iconSize, dm) (isVerticalBarLayout()? (hotseatBarSidePaddingStartPx hotseatBarSidePaddingEndPx): (res.getDimensionPixelSize(R.dimen.dynamic_grid_hotseat_extra_vertical_size) hotseatBarTopPaddingPx hotseatBarBottomPaddingPx))*/;
