客户有要求直接显示app列表页面，不显示桌面，网上查了基本都是处理的桌面(workspace)，后被我找到方法，独辟蹊径！
add 2020.1.13
发现右键居然还能操作，回到上层界面，再改：
路径：
packages\apps\Launcher3\src\com\android\launcher3\allapps\AllAppsContainerView.java
@Override
public boolean dispatchKeyEvent(KeyEvent event) {
Log.e(TAG, "into dispatchKeyEvent...");
mSearchUiManager.preDispatchKeyEvent(event);
+return true;
-//return super.dispatchKeyEvent(event);
}
1、路径： 函数：setupViews 最后
packages\apps\Launcher3\src\com\android\launcher3\Launcher.java添加：
....
// Setup Apps
mAppsView = findViewById(R.id.apps_view);
// Setup the drag controller (drop targets have to be added in reverse order in priority)
mDragController.setMoveTarget(mWorkspace);
mDropTargetBar.setup(mDragController);
mAllAppsController.setupViews(mAppsView);
+goAppsView();
}
private void goAppsView(){
Launcher mLauncher = Launcher.getLauncher(this);
if (!mLauncher.isInState(ALL_APPS)) {
mLauncher.getUserEventDispatcher().logActionOnControl(Action.Touch.TAP,
ControlType.ALL_APPS_BUTTON);
mLauncher.getStateManager().goToState(ALL_APPS);
}
}2、禁止上下滑动的地方和网上的一样，可以在下面找打。
//=========================================================
以下为网上查到的方法：
1、直接在桌面上显示 app
路径1、
packages\apps\Launcher3\src\com\android\launcher3\config\BaseFlags.java添加：
添加变量：
abstract class BaseFlags {
BaseFlags() {}
+ public static final boolean REMOVE_DRAWER = true;
public static final boolean IS_DOGFOOD_BUILD = false;
public static final String AUTHORITY = "com.android.launcher3.settings".intern();
...路径2、
packages\apps\Launcher3\src\com\android\launcher3\model\BaseModelUpdateTask.java修改：
@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.
-//return;
+if(!FeatureFlags.REMOVE_DRAWER){
+ return;
+}
}
execute(mApp, mDataModel, mAllAppsList);
}路径3、
packages\apps\Launcher3\src\com\android\launcher3\model\LoaderTask.java修改：
// second step
TraceHelper.partitionSection(TAG, "step 2.1: loading all apps");
loadAllApps();
+if (FeatureFlags.REMOVE_DRAWER)
+{
+ verifyApplications();
+}
TraceHelper.partitionSection(TAG, "step 2.2: Binding all apps");
verifyNotStopped();
mResults.bindAllApps(); //add by yy
private void verifyApplications() {
final Context context = mApp.getContext();
ArrayList<Pair<ItemInfo, Object>> installQueue = new ArrayList<>();
final List<UserHandle> profiles = mUserManager.getUserProfiles();
for (UserHandle user : profiles) {
final List<LauncherActivityInfo> apps = mLauncherApps.getActivityList(null, user);
ArrayList<InstallShortcutReceiver.PendingInstallShortcutInfo> added = new ArrayList<InstallShortcutReceiver.PendingInstallShortcutInfo>();
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);
}
}
}
//end add by yy2、禁止上滑，显示app
路径：
packages\apps\Launcher3\quickstep\src\com\android\launcher3\uioverrides\OverviewToAllAppsTouchController.java修改：
@Override
protected boolean canInterceptTouch(MotionEvent ev) {
+if(FeatureFlags.REMOVE_DRAWER){
+ return false;
+}
if (mCurrentAnimation != null) {
// If we are already animating from a previous state, we can intercept.
return true;
}
...3、禁止桌面左右滑动
路径：
packages\apps\Launcher3\src\com\android\launcher3\PagedView.java修改：
+ if(FeatureFlags.REMOVE_DRAWER){
+ Log.e(TAG, "into MotionEvent.ACTION_UP ==>>"+action);
+ //returnToOriginalPage = true;
+ snapToPageWithVelocity(mCurrentPage, velocityX);
+ }
+ /*
int finalPage;
// We give flings precedence over large moves, which is why we short-circuit our
// test for a large move if a fling has been registered. That is, a large
// move to the left and fling to the right will register as a fling to the right.
boolean isDeltaXLeft = mIsRtl ? deltaX > 0 : deltaX < 0;
boolean isVelocityXLeft = mIsRtl ? velocityX > 0 : velocityX < 0;
if (((isSignificantMove && !isDeltaXLeft && !isFling) ||
(isFling && !isVelocityXLeft)) && mCurrentPage > 0) {
finalPage = returnToOriginalPage ? mCurrentPage : mCurrentPage - 1;
Log.e(TAG, "into snapToPageWithVelocity1 ==>>"+finalPage);
snapToPageWithVelocity(finalPage, velocityX);
} else if (((isSignificantMove && isDeltaXLeft && !isFling) ||
(isFling && isVelocityXLeft)) &&
mCurrentPage < getChildCount() - 1) {
finalPage = returnToOriginalPage ? mCurrentPage : mCurrentPage + 1;
Log.e(TAG, "into snapToPageWithVelocity2 ==>>"+finalPage);
snapToPageWithVelocity(finalPage, velocityX);
} else {
snapToDestination();
}
+ */4、禁止 桌面应用图标长按事件
路径：
packages\apps\Launcher3\src\com\android\launcher3\allapps\AllAppsGridAdapter.java
@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
switch (viewType) {
case VIEW_TYPE_ICON:
BubbleTextView icon = (BubbleTextView) mLayoutInflater.inflate(
R.layout.all_apps_icon, parent, false);
icon.setOnClickListener(ItemClickHandler.INSTANCE);
+ //icon.setOnLongClickListener(ItemLongClickListener.INSTANCE_ALL_APPS);
icon.setLongPressTimeout(ViewConfiguration.getLongPressTimeout());
icon.setOnFocusChangeListener(mIconFocusListener);
...路径：
packages\apps\Launcher3\src\com\android\launcher3\Workspace.java修改：
...
child.setHapticFeedbackEnabled(false);
+ //child.setOnLongClickListener(ItemLongClickListener.INSTANCE_WORKSPACE);
if (child instanceof DropTarget) {
mDragController.addDropTarget((DropTarget) child);
}
}
