参数说明

Hotseat
Hotseat的设计目的是为了方便用户快速访问这些高频应用，而无需返回到主屏幕或通过应用抽屉查找。通常在底部显示。在常规的手机桌面中，通常是 电话、联系人、浏览器、相机。

在 android13-sdk/packages/apps/Launcher3/res/xml/device_profiles.xml 中配置Hotseat相关的属性：

首先观察device_profiles.xml代码，一般大屏（平板）设备会加载6*5的布局，手机设备会加载手机的布局，该文件里定义了4个不同的布局类型，如何确定设备加载哪个布局呢？你可以在桌面长按应用图标，然后观察可以移动多少个格子，然后根据行列数找到要修改的布局位置。比如我设备是加载6 * 5布局

    </grid-option>
</profiles>

这里涉及到 Hotseat 设置地方就下面几个：

launcher:numHotseatIcons="5"

设置显示hotseat的应用数量

launcher:hotseatColumnSpanLandscape="4"

在横屏模式下，hotseat占用的列数（竖屏模式下，默认占满，即与桌面上应用的列数一致）

launcher:hotseatBarBottomSpace="76"

竖屏模式下的底部间距

launcher:hotseatBarBottomSpaceLandscape="40"

横屏模式下的底部间距

如何添加相应的Hotseat组件?

组件配置通常位于 android13-sdk/packages/apps/Launcher3/res/xml/ 下的 default_workspace_MxN.xml
其中 M 表示行 N 表示列：一行可以放下 M 个图标，一列可以放下 N 个图标。

例如我测试发现我用的是 default_workspace_6x5.xml ，里面的一个 resolve 节点就对应一个图标。

例如录音机图标：

    <resolve
        launcher:container="-101"
        launcher:screen="0"
        launcher:x="0"
        launcher:y="0" >
		<favorite
           launcher:uri="#Intent;action=android.intent.action.MAIN;category=android.intent.category.LAUNCHER;launchFlags=0x10200000;component=com.android.soundrecorder/.SoundRecorder;end" />
    </resolve>

launcher:container="-101" 代表唯一hotseat位置。
launcher:screen="0" 表示第一格，下一个图标递增。
launcher:x="0" 表示x坐标，其他的图标递增。
launcher:y="0" 表示y坐标,后续的y坐标也是0。
<favorite
launcher:uri= 后面填应用的intent信息，数据库里面复制出来就可以了

这里又有一个问题，其他应用的 launcher:uri= 参数怎么设置？

点击展开更多

  1. 首先打开机器将要布局的图标手动移动到 hotseat 位置上面。

  2. 然后使用 adb 命令将 data/data/com.android.launcher3/databases 这个文件 pull 出来。这个文件夹是 Luancher 的数据库文件。里面保存了相关应用的图标信息。

  3. 使用 SQLiteStudio 工具打开 pull 出来的 db 文件。打开 Tables 下的表格就可以看到图标信息了。

如果你发现设置后显示不全，那你要确保 device_profiles.xml 的 launcher:numHotseatIcons="X"，这个 X 要设置成为你要显示的hotseat个数。

hotseat布局方向修改

参考：Android 13 Hotseat定制化修改——001 hotseat布局方向​ 一.背景 由于需求是 - 掘金

直接修改 DeviceProfile 类中的 isVerticalBarLayout 方法让其全局修改成横屏（false）或者竖屏（true），如下是修改成横屏方式。

横屏（false）则 hotseat 是显示在屏幕下方
竖屏（true）则hotseat 是显示在屏幕侧方

谷歌搜索栏位置/大小设置

  1. 修改 Launcher3\res\xml\device_profiles.xml 这里 launcher:numSearchContainerColumns="5" 修改谷歌搜索框占据5个格子（横屏总共7个格子

<--这个行数可以根据自己想要的效果修改，比如我就改了7*6布局,6行7列--/>	
	<grid-option
        launcher:name="6_by_5"
        launcher:numRows="6" 
        launcher:numColumns="7"
        launcher:numSearchContainerColumns="5"
        launcher:numFolderRows="3"
        launcher:numFolderColumns="4"
        launcher:numHotseatIcons="0"
        launcher:hotseatColumnSpanLandscape="2"
        launcher:numAllAppsColumns="6"
        launcher:isScalable="true"
        launcher:inlineNavButtonsEndSpacing="@dimen/taskbar_button_margin_6_5"
        launcher:devicePaddingId="@xml/paddings_6x5"
        launcher:dbFile="launcher_6_by_5.db"
        launcher:defaultLayoutId="@xml/default_workspace_6x5"
        launcher:deviceCategory="tablet" >

  1. 谷歌搜索框的位置在workspace.java里面修改，在该类里面查找这个方法：bindAndInitFirstWorkspaceScreen，定位到这里

public void bindAndInitFirstWorkspaceScreen() {
        if (!FeatureFlags.QSB_ON_FIRST_SCREEN) {
            return;
        }

        // Add the first page
        CellLayout firstPage = insertNewWorkspaceScreen(Workspace.FIRST_SCREEN_ID, getChildCount());
        // Always add a first page pinned widget on the first screen.
        if (mFirstPagePinnedItem == null) {
            // In transposed layout, we add the first page pinned widget in the Grid.
            // As workspace does not touch the edges, we do not need a full
            // width first page pinned widget.
            mFirstPagePinnedItem = LayoutInflater.from(getContext())
                    .inflate(R.layout.search_container_workspace, firstPage, false);
        }

        int cellHSpan = mLauncher.getDeviceProfile().inv.numSearchContainerColumns;
        //格子数从0开始算，这里表示搜索框位置从X轴第2格子，y轴第3个格子算起，x轴占据5(cellHSpan)个格子，y轴占据1个格子
        CellLayoutLayoutParams lp = new CellLayoutLayoutParams(1, 2, cellHSpan, 1);
        lp.canReorder = false;
        if (!firstPage.addViewToCellLayout(
                mFirstPagePinnedItem, 0, R.id.search_container_workspace, lp, true)) {
            Log.e(TAG, "Failed to add to item at (0, 0) to CellLayout");
            mFirstPagePinnedItem = null;
        }
    }

  1. 还要在LoaderCursor.java的checkItemPlacement()方法中修改搜索框对位置的占用效果：

// Launcher3/src/com/android/launcher3/model/LoaderCursor.java
/**
 * check & update map of what's occupied; used to discard overlapping/invalid items
 */
protected boolean checkItemPlacement(ItemInfo item) {
    int containerIndex = item.screenId;
	// ...

    if (!occupied.containsKey(item.screenId)) {
        GridOccupancy screen = new GridOccupancy(countX + 1, countY + 1);
        if (item.screenId == Workspace.FIRST_SCREEN_ID && FeatureFlags.QSB_ON_FIRST_SCREEN) {
            int spanX = mIDP.numSearchContainerColumns;
            int spanY = 1;
            // 这里需要跟WorkSpace.java中设置的搜索框位置保持一致
            screen.markCells(1, 2, spanX, spanY, true);
        }
        occupied.put(item.screenId, screen);
    }
    final GridOccupancy occupancy = occupied.get(item.screenId);

    // Check if any workspace icons overlap with each other
    if (occupancy.isRegionVacant(item.cellX, item.cellY, item.spanX, item.spanY)) {
        occupancy.markCells(item, true);
        return true;
    } else {
        Log.e(TAG, "Error loading shortcut " + item
                + " into cell (" + containerIndex + "-" + item.screenId + ":"
                + item.cellX + "," + item.cellX + "," + item.spanX + "," + item.spanY
                + ") already occupied");
        return false;
    }
}

如果只修改WorkSpace、而没有修改LoaderCursor中的代码，那么搜索框原本的布局(默认位置是x=0，y=0)占用效果会一直存在，导致后面一些应用或者组件无法放置在首页的首行位置。
