android 9.0 Launcher3 去掉抽屉式,显示所有 app
修改思路
1、增加全局控制变量 sys.launcher3.is_full_app，用来动态切换
2、增加两套布局，对应有抽屉和无抽屉
3、去除 allAppsButton
4、将 AllAppsContainerView 中的图标加载到 Workspace
5、新安装的 app 自动添加图标到 Workspace
6、替换 Workspace 图标长按删除选项为取消
7、屏蔽上拉显示抽屉页面手势
8、修改页面指示线为圆点
上代码
1、增加全局控制变量 sys.launcher3.is_full_app
1) 在 LauncherAppState 中增加静态方法 isDisableAllApps(), 通过修改 Settings 中自定义的值 sys.launcher3.is_full_app
vendor\mediatek\proprietary\packages\apps\Launcher3\src\com\android\launcher3\LauncherAppState.java
private static Context mContext;
public static boolean isDisableAllApps() {
if (mContext != null) {
return Settings.System.getInt(mContext.getContentResolver(),
"sys.launcher3.is_full_app", 0) == 1;
}
return true;
}
vendor\mediatek\proprietary\packages\apps\Launcher3\AndroidManifest-common.xml
2) AndroidManifest-common.xml 中增加权限
> installQueue = new ArrayList<>();
final List profiles = mUserManager.getUserProfiles();
for (UserHandle user : profiles) {
final List apps = mLauncherApps.getActivityList(null, user);
ArrayList added = new ArrayList();
synchronized (this) {
for (LauncherActivityInfo app : apps) {
InstallShortcutReceiver.PendingInstallShortcutInfo pendingInstallShortcutInfo = new InstallShortcutReceiver.PendingInstallShortcutInfo(app, context);
added.add(pendingInstallShortcutInfo);
installQueue.add(pendingInstallShortcutInfo.getItemInfo());
}
}
if (!added.isEmpty()) {
mApp.getModel().addAndBindAddedWorkspaceItems(installQueue);
}
}
}
vendor\mediatek\proprietary\packages\apps\Launcher3\src\com\android\launcher3\model\BaseModelUpdateTask.java
注释 run() 中的 return
@Override
public final void run() {
if (!mModel.isModelLoaded()) {
if (DEBUG_TASKS) {
Log.d(TAG, "Ignoring model task since loader is pending=" + this);
}
// Loader has not yet run.
//annotaion for load all app on workspace
// return;
}
execute(mApp, mDataModel, mAllAppsList);
}
5、新安装的 app 自动添加图标到 Workspace
vendor\mediatek\proprietary\packages\apps\Launcher3\src\com\android\launcher3\model\PackageUpdatedTask.java
execute() 中增加判断，添加 updateToWorkSpace()
public void execute(LauncherAppState app, BgDataModel dataModel, AllAppsList appsList) {
....
final ArrayList addedOrModified = new ArrayList<>();
addedOrModified.addAll(appsList.added);
//add for load new install app on workspace
if (LauncherAppState.isDisableAllApps()) {
android.util.Log.e("cczLauncher3", "updateToWorkSpace()");
updateToWorkSpace(context, app, appsList);
}
...
}
//add for load new install app on workspace
public void updateToWorkSpace(Context context, LauncherAppState app , AllAppsList appsList){
ArrayList> installQueue = new ArrayList<>();
final List profiles = UserManagerCompat.getInstance(context).getUserProfiles();
ArrayList added
= new ArrayList();
for (UserHandle user : profiles) {
final List apps = LauncherAppsCompat.getInstance(context).getActivityList(null, user);
synchronized (this) {
for (LauncherActivityInfo info : apps) {
for (AppInfo appInfo : appsList.added) {
if(info.getComponentName().equals(appInfo.componentName)){
InstallShortcutReceiver.PendingInstallShortcutInfo mPendingInstallShortcutInfo
= new InstallShortcutReceiver.PendingInstallShortcutInfo(info,context);
added.add(mPendingInstallShortcutInfo);
installQueue.add(mPendingInstallShortcutInfo.getItemInfo());
}
}
}
}
}
if (!added.isEmpty()) {
app.getModel().addAndBindAddedWorkspaceItems(installQueue);
}
}
6、替换 Workspace 图标长按删除选项为取消
vendor\mediatek\proprietary\packages\apps\Launcher3\src\com\android\launcher3\DeleteDropTarget.java
在 setTextBasedOnDragSource() 、setControlTypeBasedOnDragSource()、onAccessibilityDrop() 中分别增加判断是否需要删除图标
private void setTextBasedOnDragSource(It
