  修改Launcher2.java的代码
  (文件位置: /alps/packages/apps/Launcher2/src/com/android/launcher2/Launcher.java)
  网站查看源码:
  https://www.androidos.net.cn/android/6.0.1_r16/xref/packages/apps/Launcher2/src/com/android/launcher2/Launcher.java

Launcher2.java部分源码如下:

······
public void showFirstRunWorkspaceCling() {
        // Enable the clings only if they have not been dismissed before
        if (isClingsEnabled() &&
                !mSharedPrefs.getBoolean(Cling.WORKSPACE_CLING_DISMISSED_KEY, false) &&//此处false改为true
                !skipCustomClingIfNoAccounts() ) {
            // If we're not using the default workspace layout, replace workspace cling
            // with a custom workspace cling (usually specified in an overlay)
            // For now, only do this on tablets
            if (mSharedPrefs.getInt(LauncherProvider.DEFAULT_WORKSPACE_RESOURCE_ID, 0) != 0 &&
                    getResources().getBoolean(R.bool.config_useCustomClings)) {
                // Use a custom cling
                View cling = findViewById(R.id.workspace_cling);
                ViewGroup clingParent = (ViewGroup) cling.getParent();
                int clingIndex = clingParent.indexOfChild(cling);
                clingParent.removeViewAt(clingIndex);
                View customCling = mInflater.inflate(R.layout.custom_workspace_cling, clingParent, false);
                clingParent.addView(customCling, clingIndex);
                customCling.setId(R.id.workspace_cling);
            }
            initCling(R.id.workspace_cling, null, false, 0);
        } else {
            removeCling(R.id.workspace_cling);
        }
    }
    public void showFirstRunAllAppsCling(int[] position) {
        // Enable the clings only if they have not been dismissed before
        if (isClingsEnabled() &&
                !mSharedPrefs.getBoolean(Cling.ALLAPPS_CLING_DISMISSED_KEY, false)) {//此处false改为true
            initCling(R.id.all_apps_cling, position, true, 0);
        } else {
            removeCling(R.id.all_apps_cling);
        }
    }
    public Cling showFirstRunFoldersCling() {
        // Enable the clings only if they have not been dismissed before
        if (isClingsEnabled() &&
                !mSharedPrefs.getBoolean(Cling.FOLDER_CLING_DISMISSED_KEY, false)) {//此处false改为true
            return initCling(R.id.folder_cling, null, true, 0);
        } else {
            removeCling(R.id.folder_cling);
            return null;
        }
    }
······

修改如下:

-   !mSharedPrefs.getBoolean(Cling.WORKSPACE_CLING_DISMISSED_KEY, false) &&
+   !mSharedPrefs.getBoolean(Cling.WORKSPACE_CLING_DISMISSED_KEY, true) &&

-   !mSharedPrefs.getBoolean(Cling.ALLAPPS_CLING_DISMISSED_KEY, false)) 
+   !mSharedPrefs.getBoolean(Cling.ALLAPPS_CLING_DISMISSED_KEY, true)) 

-   !mSharedPrefs.getBoolean(Cling.FOLDER_CLING_DISMISSED_KEY, false)) 
+   !mSharedPrefs.getBoolean(Cling.FOLDER_CLING_DISMISSED_KEY, true))
