Launcher3 去掉搜桌面索框
实现需求说明
每个平台平台源码有区别比如MTK、高通、展讯、RK、谷歌…单个平台下 不同Android版本对应的模块源码也不一样
当前针对的是MTK Android12 来实现去掉搜索框功能其它平台可借鉴部分实现思路。网上部分资料也因为不同平台不同版本可能只能解决部分问题。实际还是需要自己针对性看源码分析源码实现。
搜索框 有两部分 主界面和所有应用的谷歌搜索框

实际这个需求实现 在不同的平台和版本区别很大借鉴解决思路。
解决方案
解决方案找到对应表的布局将布局中的View com.android.launcher3.allapps.search.AppsSearchContainerLayout 设置为GONE 状态
代码跟踪
首先看Launcher 目录有一个allapps 自己猜是所有app 的意思吧 看着像的就去看一下源码 ![(https://i-blog.csdnimg.cn/direct/6e65499862dc4d60a68dc2f1d2878f46.png) 在AllAppsContainerView.java 文件中有这样一段代码初始化View 这个search 相关的 search_container_all_apps看着像mSearchContainer findViewById(R.id.search_container_all_apps);mSearchUiManager (SearchUiManager) mSearchContainer;mSearchUiManager.initializeSearch(this);mSearchContainer.setVisibility(View.GONE);那就找 search_container_all_apps grep -rn search_container_all_apps 一次
fise4ubuntu-PowerEdge-R730:~/Android/mt6769-alps-release-s0.mp1.rc/alps-release-s0.mp1.rc$ grep -rn search_container_all_apps
packages/apps/Launcher3/res/values/config.xml:108: item typeid namesearch_container_all_apps /

packages/apps/Launcher3/tests/tapl/com/android/launcher3/tapl/AllApps.java:203: return mLauncher.waitForObjectInContainer(allAppsContainer, search_container_all_apps);
整理出有用的信息如下
packages/apps/Launcher3/res/values/config.xml:108: item typeid namesearch_container_all_apps /
packages/apps/Launcher3/res/layout/secondary_launcher.xml:102: android:idid/search_container_all_apps
packages/apps/Launcher3/res/layout/search_container_all_apps.xml:18: android:idid/search_container_all_apps
packages/apps/Launcher3/res/layout/all_apps.xml:48: layoutlayout/search_container_all_apps/
再次搜索对应的文件
secondary_launcher.xml 找到 SecondaryDisplayLauncher.java 对应search_container_all_apps.xml - 无all_apps.xml - 无
我们看看secondary_launcher.xml 发现有一个搜索的View, AppsSearchContainerLayout 设置为GONE 状态就是 search_container_all_apps 对应的View

/com.android.launcher3.secondarydisplay.SecondaryDragLayer代码扩展
上面的更改已经实现了需求我们接着看 secondary_launcher.xml 对应的Java 文件
AllAppsContainerView.java onFinishInflate() 方法Overrideprotected void onFinishInflate() {super.onFinishInflate();Log.d(TAG,onFinishInflate);// This is a focus listener that proxies focus from a view into the list view. This is to// work around the search box from getting first focus and showing the cursor.setOnFocusChangeListener((v, hasFocus) - {if (hasFocus getActiveRecyclerView() ! null) {getActiveRecyclerView().requestFocus();}});mHeader findViewById(R.id.all_apps_header);rebindAdapters(mUsingTabs, true /* force */);mSearchContainer findViewById(R.id.search_container_all_apps); //搜索框找的就是这个搜索框mSearchUiManager (SearchUiManager) mSearchContainer;mSearchUiManager.initializeSearch(this);//下面代码自己添加的mSearchContainer.setVisibility(View.GONE);Log.d(TAG, findViewById search_container_all_apps GONE);}
实际验证在不修改布局情况下这里设置GONE 没有用
跟踪mSearchContainer 对外提供的方法public View getSearchView() {return mSearchContainer;}搜索 getSearchView() 方法fise4ubuntu-PowerEdge-R730:~/Android/mt6769-alps-release-s0.mp1.rc/alps-release-s0.mp1.rc/packages/apps/Launcher3$ grep -rn getSearchView
src/com/android/launcher3/allapps/AllAppsContainerView.java:586: public View getSearchView() {
src/com/android/launcher3/allapps/AllAppsContainerView.java:806: (int) (getSearchView().getAlpha() * 255));
src/com/android/launcher3/allapps/AllAppsContainerView.java:809: getSearchView().setBackgroundColor(viewBG);
src/com/android/launcher3/allapps/AllAppsContainerView.java:816: getSearchView().setVisibility(View.GONE);这些都是 AllAppsContainerView.java 里面获取View 回头看 secondary_launcher.xml 对应的类是SecondaryDisplayLauncher.java 找到 SecondaryDisplayLauncher.java showAppDrawer 方法,在这个方法里去通过getSearchView 获取到搜索框然后对搜索框设置GONE 不显示也可以的。/*** Show/hide app drawer card with animation.*/public void showAppDrawer(boolean show) {Log.d(TAG, showAppDrawer show);if (show mAppDrawerShown) {return;}float openR (float) Math.hypot(mAppsView.getWidth(), mAppsView.getHeight());float closeR Themes.getDialogCornerRadius(this);float startR mAppsButton.getWidth() / 2f;float[] buttonPos new float[] { startR, startR};mDragLayer.getDescendantCoordRelativeToSelf(mAppsButton, buttonPos);mDragLayer.mapCoordInSelfToDescendant(mAppsView, buttonPos);final Animator animator ViewAnimationUtils.createCircularReveal(mAppsView,(int) buttonPos[0], (int) buttonPos[1],show ? closeR : openR, show ? openR : closeR);if (show) {mAppDrawerShown true;mAppsView.setVisibility(View.VISIBLE);mAppsButton.setVisibility(View.INVISIBLE);} else {mAppDrawerShown false;animator.addListener(new AnimatorListenerAdapter() {Overridepublic void onAnimationEnd(Animator animation) {mAppsView.setVisibility(View.INVISIBLE);mAppsButton.setVisibility(View.VISIBLE);mAppsView.getSearchUiManager().resetSearch();}});}Log.d(TAG, showAppDrawer set searchView Gone);//设置为 GONE mAppsView.getSearchView().setVisibility(View.GONE);animator.start();}
showAppDrawer 方法只是在特定的情况下执行所以在这个方法里面执行设置GONE逻辑并不是完全之策最简单直接就是更改布局GONE 状态了。
