Android Launcher 部分修改（6.0）

Android Launcher 部分修改（6.0）

这些天小小地修改了下6.0的Launcher，零零散散找了很多资料，现将有用到的部分在此汇个总，做个笔记

有些修改后需格式化刷机

Hotset横屏展示

config.xml中<bool name="hotseat_transpose_layout_with_orientation">false</bool>hotseat.java 中onFinishInflate()方法// 屏蔽其它方向设置//if (grid.isLandscape && !grid.isLargeTablet) {//    mContent.setGridSize(1, (int) grid.inv.numHotseatIcons);//} else {// 固定横屏底部展示mContent.setGridSize((int) grid.inv.numHotseatIcons, 1);//}

隐藏桌面上的图标

Y:\mggd\android\device\softwinner\astar-d7\overlay\packages\apps\Launcher3\res\xml\default_workspace_5x6.xml
在default_workspace.xml中注释掉要隐藏的内容

示例：

Launcher3桌面的行数和列数是动态计算的,如何修改?

* 桌面行、列计算部分转自 LYJ的IT生活 *

Launcher3桌面的行数和列数都是在InvariantDeviceProfile.java和DeviceProfile.java中动态计算的,xml中无法配置。
Note:L版本无InvariantDeviceProfile.java,是DynamicGrid.java,但是计算方法都是一样的。
InvariantDeviceProfile中用InvariantDeviceProfile来配置各种屏幕的手机桌面。

ArrayList<InvariantDeviceProfile> getPredefinedDeviceProfiles() {ArrayList<InvariantDeviceProfile> predefinedDeviceProfiles = new ArrayList<>();// width, height, #rows, #columns, #folder rows, #folder columns,// iconSize, iconTextSize, #hotseat, #hotseatIconSize, defaultLayoutId.predefinedDeviceProfiles.add(new InvariantDeviceProfile("Super Short Stubby",255, 300,     2, 3, 2, 3, 3, 48, 13, 3, 48, R.xml.default_workspace_4x4));predefinedDeviceProfiles.add(new InvariantDeviceProfile("Shorter Stubby",255, 400,     3, 3, 3, 3, 3, 48, 13, 3, 48, R.xml.default_workspace_4x4));predefinedDeviceProfiles.add(new InvariantDeviceProfile("Short Stubby",275, 420,     3, 4, 3, 4, 4, 48, 13, 5, 48, R.xml.default_workspace_4x4));predefinedDeviceProfiles.add(new InvariantDeviceProfile("Stubby",255, 450,     3, 4, 3, 4, 4, 48, 13, 5, 48, R.xml.default_workspace_4x4));predefinedDeviceProfiles.add(new InvariantDeviceProfile("Nexus S",296, 491.33f, 4, 4, 4, 4, 4, 48, 13, 5, 48, R.xml.default_workspace_4x4));predefinedDeviceProfiles.add(new InvariantDeviceProfile("Nexus 4",335, 567,     4, 4, 4, 4, 4, DEFAULT_ICON_SIZE_DP, 13, 5, 56, R.xml.default_workspace_4x4));predefinedDeviceProfiles.add(new InvariantDeviceProfile("Nexus 5",359, 567,     4, 4, 4, 4, 4, DEFAULT_ICON_SIZE_DP, 13, 5, 56, R.xml.default_workspace_4x4));predefinedDeviceProfiles.add(new InvariantDeviceProfile("Large Phone",406, 694,     5, 5, 4, 4, 4, 64, 14.4f,  5, 56, R.xml.default_workspace_5x5));// The tablet profile is odd in that the landscape orientation// also includes the nav bar on the sidepredefinedDeviceProfiles.add(new InvariantDeviceProfile("Nexus 7",//575, 904,     5, 6, 4, 5, 4, 72, 14.4f,  7, 60, R.xml.default_workspace_5x6));// 更改桌面行数为 4 * 5575, 904,     4, 5, 4, 5, 4, 72, 14.4f,  7, 60, R.xml.default_workspace_5x6));// Larger tablet profiles always have system bars on the top & bottompredefinedDeviceProfiles.add(new InvariantDeviceProfile("Nexus 10",727, 1207,    5, 6, 4, 5, 4, 76, 14.4f,  7, 64, R.xml.default_workspace_5x6));predefinedDeviceProfiles.add(new InvariantDeviceProfile("20-inch Tablet",1527, 2527,   7, 7, 6, 6, 4, 100, 20,  7, 72, R.xml.default_workspace_4x4));return predefinedDeviceProfiles;}

InvariantDeviceProfile的各个参数依次代表:

配置名字(任意定义)、最小宽度(单位是dp)、最小高度(单位是dp)、桌面行数、桌面列数、文件夹行数、文件夹列数、主菜单中predicted apps最小列数、桌面Icon的size(单位是dp)、桌面Icon的文字size(单位是dp)、Hotseat的Icon个数、Hotseat的Icon的size(单位是dp)、默认的桌面配置LayoutId。

PS:
如何由手机分辨率计算最小宽度、最小高度?
例如:手机分辨率为720*1280,DPI=320。
竖屏时:X*Y=720*1230(1230=屏幕高度-状态栏高度-NavigationBar高度)
横屏时:Y*X=646*1280(646=屏幕宽度-状态栏高度-NavigationBar高度)
最小宽度为:323=Min(720,646)/(320/160)
最小高度为:615=Min(1230,1280)/(320/160)
