7.1 Launcher3 去掉应用抽屉.docx
1 去除 all_apps_handle 键，调整 HotSeat 布局
2 去掉 searchBox bar
3 将所有应用摆在 launcher 第一层
4 去掉长按时删除选项
5 重复图标和异常
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，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、去掉向上滑动的箭头提示 all_apps_handle
packages/apps/Launcher3/src/com/android/launcher3/pageindicators/PageIndicatorLineCaret.ja
va
mAllAppsHandle.setOnClickListener(mLauncher);
mAllAppsHandle.setOnLongClickListener(mLauncher);
mAllAppsHandle.setOnFocusChangeListener(mLauncher.mFocusHandler);
mAllAppsHandle.setVisibility(GONE);//modify by luoyalong for 20180315
mLauncher.setAllAppsButton(mAllAppsHandle);
+
2、去掉第一屏 firstPage
packages/apps/Launcher3/src/com/android/launcher3/Workspace.java
public void removeAllWorkspaceScreens() {
……………….
removeAllViews();
mScreenOrder.clear();
mWorkspaceScreens.clear();
// Ensure that the first page is always present
//bindAndInitFirstWorkspaceScreen(qsb); ;//modify by luoyalong for 20180315
// Re-enable the layout transitions
enableLayoutTransitions();
}
3、去掉 searchBox bar
packages/apps/Launcher3/res/layout/qsb_default_view.xml
屏蔽掉 FrameLayout 中 布局
packages/apps/Launcher3/src/com/android/launcher3/QsbContainerView.java
public void onClick(View view) {
-
+ /*if (view.getId() == R.id.btn_qsb_search) {
if (view.getId() == R.id.btn_qsb_search) {
getActivity().startSearch("", false, null, true);
} else if (view.getId() == R.id.btn_qsb_setup) {
// Allocate a new widget id for QSB
@@ -181,7 +181,7 @@ public class QsbContainerView extends FrameLayout {
intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID,
sSavedWidgetId);

-
+
-

-
+
}
}*/
private View getDefaultView(LayoutInflater inflater, ViewGroup parent, boolean showSetup) {
View v = inflater.inflate(R.layout.qsb_default_view, parent, false);
if (showSetup) {
/*if (showSetup) {
View setupButton = v.findViewById(R.id.btn_qsb_setup);
setupButton.setVisibility(View.VISIBLE);
setupButton.setOnClickListener(this);
}
v.findViewById(R.id.btn_qsb_search).setOnClickListener(this);
v.findViewById(R.id.btn_qsb_search).setOnClickListener(this);*/
return v;
packages/apps/Launcher3/src/com/android/launcher3/Workspace.java
CellLayout.LayoutParams lp = new CellLayout.LayoutParams(0, 0, firstPage.getCountX(),
-
1);
+
firstPage.getCountX(), 1);
/*CellLayout.LayoutParams
lp = new CellLayout.LayoutParams(0, 0,
lp.canReorder = false;
if (!firstPage.addViewToCellLayout(qsb, 0, getEmbeddedQsbId(), lp, true)) {
Log.e(TAG, "Failed to add to item at (0, 0) to CellLayout");
-
+
}
}*/
4、去掉向上滑动的动画效果
packages/apps/Launcher3/src/com/android/launcher3/Launcher.java
public void showOverviewMode(boolean animated) {
showOverviewMode(animated, false);
//showOverviewMode(animated, false);//modify by luoyalong for 20180315
}
5、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
packages/apps/Launcher3/src/com/android/launcher3/DeleteDropTarget.java
protected boolean supportsDrop(DragSource source, ItemInfo info) {
//modify by luoyalong for 20180315 begin
if (LauncherAppState.isDisableAllApps()) {
if (info instanceof ShortcutInfo) {
ShortcutInfo item = (ShortcutInfo) info;
return
item.itemType
!=
LauncherSettings.BaseLauncherColumns.ITEM_TYPE_APPLICATION;
}
return info instanceof LauncherAppWidgetInfo;
}
return (info instanceof ShortcutInfo)
|| (info instanceof LauncherAppWidgetInfo)
|| (info instanceof FolderInfo);
//modify by luoyalong for 20180315 end
}
6、去掉 hotseat
去掉 hotseat 布局文件
packages/apps/Launcher3/res/xml/default_workspace_5x6.xml
//mHotseat.updateColor(mExtractedColors, !mPaused);//modify by luoyalong for 20180523
mWorkspace.getPageIndicator().updateColor(mExtractedColors);
图标快速拖动异常
packages/apps/Launcher3/src/com/android/launcher3/dragndrop/DragController.java
private PointF isFlingingToDelete(DragSource source) {
-
+
if (mFlingToDeleteDropTarget == null) return null;
if (true) return null;//modify by luoyalong for 20180606
7、当安装新应用时，安装的应用添加在第一层上。
packages/apps/Launcher3/src/com/android/launcher3/LauncherModel.java
auncherModel$PackageUpdatedTask –> run():
…………..
final HashMap addedOrUpdatedApps = new
HashMap<>();
//modify by luoyalong for 20180315 begin
if (added != null) {
final ArrayList addedInfos = new ArrayList(added);
addAndBindAddedWorkspaceItems(context, addedInfos);
//addAppsToAllApps(context, added);
//modify by luoyalong for 20180315
end
for (AppInfo ai : added) {
addedOrUpdatedApps.put(ai.componentName, ai);
}
}
8、安装某些三方 apk 会出现重复图标，禁止已有快捷图标的在后台自动创建快捷方式
因为有的第三方应用会发送一个安装快捷方式的广播，接收到广播后就会在 Launcher 的
workspace 上创建快捷方式 解决方法： android 中后台自动创建快捷方式主要是通过发送
Action 为”android.intent.action.CREATE_SHORTCUT“的 broadcast，当然还会带有一些包含
icon,name 等 data
frameworks/base/services/core/java/com/android/server/am/BroadcastQueue.java
if (recIdx == 0) {
r.dispatchTime = r.receiverTime;
r.dispatchClockTime = System.currentTimeMillis();
if (DEBUG_BROADCAST_LIGHT) Slog.v(TAG_BROADCAST, "Processing ordered
broadcast ["+ mQueueName + "] " + r);
//modify by luoyalong for 20180315 begin
if("background".equals(mQueueName)&&
"com.android.launcher.action.INSTALL_SHORTCUT".equals(r.intent.getAction())){
return;
}
//modify by luoyalong for 20180315 end
}
9、无抽屉时的异常
packages/apps/Launcher3/src/com/android/launcher3/allapps/AllAppsTransitionController.ja
va
mDiscoBounceAnimation.setTarget(this);
+
+
//modify by luoyalong for 20180312 begin
if(mAppsView != null){
mAppsView.post(new Runnable() {
@Override
public void run() {

class AllAppsTransitionController
implements
TouchController, VerticalPul
mDiscoBounceAnimation.start();
}
});
}
//modify by luoyalong for 20180312 end
+
+
}
去掉桌面长按和捏动画
packages/apps/Launcher3/src/com/android/launcher3/Launcher.java
public void showOverviewMode(boolean animated) {
showOverviewMode(animated, false);//modify by luoyalong for 20180315
//showOverviewMode(animated, false);//modify by luoyalong for 20180315
-
+
}
packages/apps/Launcher3/src/com/android/launcher3/PinchAnimationManager.java
public void setAnimationProgress(float interpolatedProgress) {
float interpolatedScale = interpolatedProgress * (1f - mOverviewScale) +
mOverviewScale;
float

}
-
+
public void animateThreshold(float threshold, Workspace.State startState,
Workspace.State goingTowards) {
if (threshold == PinchThresholdManager.THRESHOLD_ONE) {
