本文介绍如何通过修改Launcher源码实现特定功能：禁用工作空间中窗口小部件的长按事件；移除AppsCustomizePagedView中的所有应用小部件页面；取消app图标长按监听；并调整AppsCustomizeTabHost中的all app小标题。

一、在WorkSpace类中禁止窗口小部件长按事件

void startDrag(CellLayout.CellInfo cellInfo) {
View child = cellInfo.cell;

ItemInfo itemInfo = (ItemInfo) child.getTag();
if(itemInfo.toString().contains("AppWidget")){//添加判断

}else if(itemInfo.toString().contains("ShortcutInfo")){//添加判断
// Make sure the drag was started by a long press as opposed to a long click.
if (!child.isInTouchMode()) {
return;
}

mDragInfo = cellInfo;
child.setVisibility(INVISIBLE);
CellLayout layout = (CellLayout) child.getParent().getParent();
layout.prepareChildForDrag(child);

child.clearFocus();
child.setPressed(false);

final Canvas canvas = new Canvas();

// The outline is used to visualize where the item will land if dropped
mDragOutline = createDragOutline(child, canvas, DRAG_BITMAP_PADDING);
beginDragShared(child, this);
}
}

二、在AppsCustomizePagedView类中去掉allApp中小部件页面

private void updatePageCounts() {
mNumWidgetPages = (int) Math.ceil(mWidgets.size() /
(float) (mWidgetCountX * mWidgetCountY));
mNumWidgetPages = 0;//把页面修改为0
mNumAppsPages = (int) Math.ceil((float) mApps.size() / (mCellCountX * mCellCountY));
}

四、PagedViewWithDraggableItems 中的onLongClick（）方法中return true取消appIcon的长安监听

五、AppsCustomizeTabHost 中去掉allapp小title

protected void onFinishInflate() {

TextView tabView;
String label;
label = getContext().getString(R.string.all_apps_button_label);
tabView = (TextView) mLayoutInflater.inflate(R.layout.tab_widget_indicator, tabs, false);
tabView.setText(label);
tabView.setContentDescription(label);
addTab(newTabSpec(APPS_TAB_TAG).setIndicator(tabView).setContent(contentFactory));
// label = getContext().getString(R.string.widgets_tab_label);
// tabView = (TextView) mLayoutInflater.inflate(R.layout.tab_widget_indicator, tabs, false);
// tabView.setText(label);
// tabView.setContentDescription(label);
// addTab(newTabSpec(WIDGETS_TAB_TAG).setIndicator(tabView).setContent(contentFactory));
setOnTabChangedListener(this);

}
