需求：去掉launcher 中全部App界面上面搜索应用框

修改位置

packages\apps\Launcher3\src\com\android\launcher3\allapps\AllAppsContainerView.java

在 onFinishInflate() 中添加一行 mSearchContainer.setVisibility(View.GONE);

@Override
protected void onFinishInflate() {
    super.onFinishInflate();

    ....

    mSearchContainer = findViewById(R.id.search_container_all_apps);
    mSearchUiManager = (SearchUiManager) mSearchContainer;
    mSearchUiManager.initialize(mApps, mAppsRecyclerView);

    Monkey.20211215 del search allapps
    mSearchContainer.setVisibility(View.GONE);

    ......
}

packages\apps\Launcher3\src\com\android\launcher3\allapps\AllAppsTransitionController.java

注释setAlphas() 中的setter.setViewAlpha()，因为最终会调用到 AlphaUpdateListener 中的 updateVisibility() 将 setVisibility 改成 VISIBLE，导致上面添加的 GONE 不生效

 private void setAlphas(LauncherState toState, PropertySetter setter) {
        int visibleElements = toState.getVisibleElements(mLauncher);
        boolean hasHeader = (visibleElements & ALL_APPS_HEADER) != 0;
        boolean hasHeaderExtra = (visibleElements & ALL_APPS_HEADER_EXTRA) != 0;
        boolean hasContent = (visibleElements & ALL_APPS_CONTENT) != 0;
		// Monkey.20211215 del search allapps
        // setter.setViewAlpha(mAppsView.getSearchView(), hasHeader ? 1 : 0, LINEAR);
		
        setter.setViewAlpha(mAppsView.getContentView(), hasContent ? 1 : 0, LINEAR);
        setter.setViewAlpha(mAppsView.getScrollBar(), hasContent ? 1 : 0, LINEAR);
        mAppsView.getFloatingHeaderView().setContentVisibility(hasHeaderExtra, hasContent, setter);

        setter.setInt(mScrimView, ScrimView.DRAG_HANDLE_ALPHA,
                (visibleElements & VERTICAL_SWIPE_INDICATOR) != 0 ? 255 : 0, LINEAR);
    }
