一、设置总开关
1、添加一个开关，控制是否去掉抽屉。
launcher3\src\com\android\launcher3\launcherappstate.java:
public static boolean isDisableAllApps() { // Returns false on non-dogfood builds. return android.os.SystemProperties.get("ro.magcomm.launcher3.ishome2","0").equals("1"); }二、allapp键的加载
在hotseat里面去掉allapp键的加载 ，屏蔽isallappsbuttonrank()占用allapp位置。
1) 不再占用allapp位置
2) 在加载workspace时,会留出hotseat的第三个位置给allapp按钮,若不取消该位置的占用,在hotseat加载时会留出空位。hotseat的初始化在hotseat.java中
launcher3\src\com\android\launcher3\hotseat.java c>isallappsbuttonrank():
public boolean isAllAppsButtonRank(int rank) { //add by liaoxiaomin begin @{ if (LauncherAppState.isDisableAllApps()) { return false; } //add by liaoxiaomin end @} return rank == mAllAppsButtonRank; }3) home2没有抽屉，所以不需要allapp按钮。在hotseat里面去掉allapp键的加载，在hotseat.java 的void resetlayout()中初始化hotseat布局。在home2时停止加载allapp按钮。
launcher3\src\com\android\launcher3\hotseat.java c>resetlayout():
void resetlayout() { mcontent.removeallviewsinlayout(); //添加 @{ if(launcherappstate.isdisableallapps()){ //添加 }@ // add the apps button context context = getcontext(); layoutinflater inflater = layoutinflater.from(context); textview allappsbutton = (textview) inflater.inflate(r.layout.all_apps_button, mcontent, false); drawable d = context.getresources().getdrawable(r.drawable.all_apps_button_icon); mlauncher.resizeicondrawable(d); allappsbutton.setcompounddrawables(null, d, null, null); allappsbutton.setcontentdescription(context.getstring(r.string.all_apps_button_label)); allappsbutton.setonkeylistener(new hotseaticonkeyeventlistener()); if (mlauncher != null) { mlauncher.setallappsbutton(allappsbutton); allappsbutton.setontouchlistener(mlauncher.gethapticfeedbacktouchlistener()); allappsbutton.setonclicklistener(mlauncher); allappsbutton.setonlongclicklistener(mlauncher); allappsbutton.setonfocuschangelistener(mlauncher.mfocushandler); } // note: we do this to ensure that the hotseat is always laid out in the orientation of // the hotseat in order regardless of which orientation they were added int x = getcellxfromorder(mallappsbuttonrank); int y = getcellyfromorder(mallappsbuttonrank); celllayout.layoutparams lp = new celllayout.layoutparams(x,y,1,1); lp.canreorder = false; mcontent.addviewtocelllayout(allappsbutton, -1, allappsbutton.getid(), lp, true); }}//别漏了这里的 }三、数据初始化类中更改hotseat布局
invariantdeviceprofile.java launcher3进行布局初始化的一个类。
在有allapp按钮时hotseat里hotseat图标数量为五个，没有allapp按钮时hotseat图标数量应为四个。
launcher3\src\com\android\launcher3\invariantdeviceprofile.java:
1)先加个宏控
//添加 @{private boolean hasda = launcherappstate.isdisableallapps();//添加 }@2)去掉抽屉时，hotseat的格数为四格，所以不能抛出异常。 ( numhotseaticons 为偶时不抛异常)
invariantdeviceprofile( ):
invariantdeviceprofile(string n, float w, float h, int r, int c, int fr, int fc, int maapc, // ensure that we have an odd number of hotseat items (since we need to place all apps) if (hs % 2 == 0&& !hasda) {// 在无抽屉情况下不抛异常 throw new runtimeexception("all device profiles must have an odd number of hotseat spaces"); } name = n; ... ...}3)去掉抽屉的情况下加载不同的布局
getpredefineddeviceprofiles() :
ArrayList getPredefinedDeviceProfiles() { ArrayList predefinedDeviceProfiles = new ArrayList<>(); // width, height, #rows, #columns, #folder rows, #folder columns, // iconSize, iconTextSize, #hotseat, #hotseatIconSize, defaultLayoutId. //modify by liaoxiaomin begin /*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("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, (hasDA ? 4 : 5), 48, (hasDA ? R.xml.default_workspace_4x4_no_all_apps : R.xml.default_workspace_4x4 ))); predefinedDeviceProfiles.add(new InvariantDeviceProfile("Stubby", 255, 450, 3, 4, 3, 4, 4, 48, 13, (hasDA ? 4 : 5), 48, (hasDA ? R.xml.default_workspace_4x4_no_all_apps : R.xml.default_workspace_4x4 ))); predefinedDeviceProfiles.add(new InvariantDeviceProfile("Nexus S", 296, 491.33f, 4, 4, 4, 4, 4, 48, 13,(hasDA ? 4 : 5), 48, (hasDA ? R.xml.default_workspace_4x4_no_all_apps : R.xml.default_workspace_4x4 ))); predefinedDeviceProfiles.add(new InvariantDeviceProfile("Nexus 4", 335, 567, 4, 4, 4, 4, 4, DEFAULT_ICON_SIZE_DP, 13, (hasDA ? 4 : 5), 56, (hasDA ? R.xml.default_workspace_4x4_no_all_apps : R.xml.default_workspace_4x4 ))); predefinedDeviceProfiles.add(new InvariantDeviceProfile("Nexus 5", 359, 567, 4, 4, 4, 4, 4, DEFAULT_ICON_SIZE_DP, 13,(hasDA ? 4 : 5), 56, (hasDA ? R.xml.default_workspace_4x4_no_all_apps : 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)); //modify by liaoxiaomin end 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 side predefinedDeviceProfiles.add(new InvariantDeviceProfile("Nexus 7", 575, 904, 5, 6, 4, 5, 4, 72, 14.4f, 7, 60, R.xml.default_workspace_5x6)); // Larger tablet profiles always have system bars on the top & bottom predefinedDeviceProfiles.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; } 4)记得改下 dw_phone_hotseat.xml 的布局 ，因为hotseat只有5格了。
四、将所有应用放在第一层
launcher3加载流程:进入 launcherapplication -> launcherappstate -> 进行初始化环境(通过传递scontext)。进行事件监听&&初始化一些环境。例如:横竖屏、当局语言、像素密度、小部件和快捷图标数据库操作对象、应用图标缓存对象、初始化launchermode等。在初始化过后，从launcher的oncreate方法入手。mmodel.startloader(mworkspace.getrestorepage());里加载数据 。在加载完成所有快捷方式后将其余为加载完的应用布局在第一层。
1) 成所有快捷方式后将其余为加载完的应用布局在第一层。
launcher3\src\com\android\launcher3\launchermodel.java:
launchermodel$loadertask c> run():
public void run() { synchronized (mLock) { if (DEBUG_LOADERS) { LauncherLog.d(TAG, "Set load task running flag >>>>, mIsLaunching = " + ",this = " + this); } if (mStopped) { return; } mIsLoaderTaskRunning = true; } // Optimize for end-user experience: if the Launcher is up and // running with the // All Apps interface in the foreground, load All Apps first. Otherwise, load the // workspace first (default). keep_running: { if (DEBUG_LOADERS) Log.d(TAG, "step 1: loading workspace"); loadAndBindWorkspace(); if (mStopped) { LauncherLog.i(TAG, "LoadTask break in the middle, this = " + this); break keep_running; } waitForIdle(); // second step if (DEBUG_LOADERS) Log.d(TAG, "step 2: loading all apps"); loadAndBindAllApps(); //add by liaoxiaomin begin @{ if (LauncherAppState.isDisableAllApps()) { verifyApplications(); } //add by liaoxiaomin end }@ } // Clear out this reference, otherwise we end up holding it until all of the // callback runnables are done. mContext = null; synchronized (mLock) { // If we are still the last one to be scheduled, remove ourselves. if (mLoaderTask == this) { mLoaderTask = null; } if (DEBUG_LOADERS) { LauncherLog.d(TAG, "Reset load task running flag <<<<, this = " + this); } mIsLoaderTaskRunning = false; mHasLoaderCompletedOnce = true; } } //add by liaoxiaomin begin private void verifyApplications() { final Context context = mApp.getContext(); // Cross reference all the applications in our apps list with items in the workspace ArrayList tmpInfos; ArrayList added = new ArrayList(); synchronized (sBgLock) { for (AppInfo app : mBgAllAppsList.data) { tmpInfos = getItemInfoForComponentName(app.componentName, app.user); if (tmpInfos.isEmpty()) { // We are missing an application icon, so add this to the workspace added.add(app); // This is a rare event, so lets log it Log.e(TAG, "Missing Application on load: " + app); } } } if (!added.isEmpty()) { addAndBindAddedWorkspaceItems(context, added); } } //add by liaoxiaomin end 五、有新应用添加时更新workspace
当安装新应用时，我们需要对左面更新，保证安装的应用添加在第一层上。
launcher3\src\com\android\launcher3\launchermodel.java:
launchermodel$packageupdatedtask c> run():
if (added != null) { // add by liaoxiaomin begin @{ if(LauncherAppState.isDisableAllApps()){ final ArrayList addedInfos = new ArrayList(added); addAndBindAddedWorkspaceItems(context, addedInfos); }else { // add by liaoxiaomin end }@ addAppsToAllApps(context, added); }// add by liaoxiaomin for (AppInfo ai : added) { addedOrUpdatedApps.put(ai.componentName, ai); } } 六、去掉长按时的删除选项
长按时，不该有删除选项 。
deletedroptarget.java: 中更改长按时的监听，开始时直接屏蔽删除按钮，后来发现应用自身发出的快捷方式无法删除 所以做了如下处理。
launcher3\src\com\android\launcher3\deletedroptarget.java c>supportsdrop():
public static boolean supportsDrop(Object info) { //add by liaoxiaomin begin @{ if (LauncherAppState.isDisableAllApps()) { if (info instanceof ShortcutInfo) { ShortcutInfo item = (ShortcutInfo) info; return item.itemType != LauncherSettings.BaseLauncherColumns.ITEM_TYPE_APPLICATION; } return info instanceof LauncherAppWidgetInfo; } //add by liaoxiaomin end }@ return (info instanceof ShortcutInfo) || (info instanceof LauncherAppWidgetInfo) || (info instanceof FolderInfo); }七、解决添加新应用后使用产生快捷方式问题
Launcher3/src/com/android/launcher3/LauncherModel.java
if (targetIntent != null && info.user.equals(user)) { String s = targetIntent.toUri(0); + //liaoxiaomin modify for launcher add item 20190514 begin + String mTargetComponentName = targetIntent.getComponent().toString(); + if(intent.getComponent() != null && mTargetComponentName.equals(intent.getComponent().toString())) { + return true; + } + //liaoxiaomin modify for launcher add item 20190514 end if (intentWithPkg.equals(s) || intentWithoutPkg.equals(s)) { return true; }
