}
修改xml文件夹下地default_workspace_xxx和dw_phone_hotseat。 修改添加顺序，默认为1，因为我去除了搜索页面，需要从0开始添加，修改AddWorkspaceItemsTask的findSpaceForItem方法
// Search on any of the screens starting from the first screen.
for (int screen = 0; screen < screenCount; screen++) {
screenId = workspaceScreens.get(screen);

app, screenItems.get(screenId), cordinates, spanX, spanY)) {
// We found a space for it
found = true;
break;
}

}
修改ScrimView的mDragHandle初始化。
protected Drawable mDragHandle = new ColorDrawable(Color.TRANSPARENT);
配置在assets/app_default_filter下面，根据包名过滤 实现在AppFilter的shouldShowApp方法
Workspace类的createUserFolderIfNecessary方法
if(LauncherSettings.Favorites.CONTAINER_HOTSEAT == container) return false;
AndroidManifest Launcher开启横竖屏 android:screenOrientation="user"
RotationHelper类notifyChange方法 else return SCREEN_ORIENTATION_USER
DeviceProfile类的adjustToHideWorkspaceLabels方法全注释(不知道为什么launcher3横屏要隐藏text)
private void notifyChange() {
if (!mInitialized || mDestroyed) {
return;
}
final int activityFlags;
if (mStateHandlerRequest != REQUEST_NONE) {
activityFlags = mStateHandlerRequest == REQUEST_LOCK ?

activityFlags = SCREEN_ORIENTATION_LOCKED;
} else if (mIgnoreAutoRotateSettings || mCurrentStateRequest == REQUEST_ROTATE
|| mAutoRotateEnabled) {
activityFlags = SCREEN_ORIENTATION_UNSPECIFIED;
} else {
// If auto rotation is off, allow rotation on the activity, in case the user is using
// forced rotation.
activityFlags = SCREEN_ORIENTATION_USER;
}
if (activityFlags != mLastActivityFlags) {
mLastActivityFlags = activityFlags;
mActivity.setRequestedOrientation(activityFlags);
}
}
