Android12 设置搜索屏蔽某个App入口

1.前言：

之前在Android12Rom定制需求中做了屏蔽Settings某个App的入口，有网络和互联网、已连接的设备、电池和存储，但是在搜索的时候还是能看到入口，所以感觉体验不是很好，于是根据要求屏蔽这几个3App的搜索功能，这里记录一下修改过程。

2.核心修改点：

StorageDashboardFragment
ConnectedDeviceDashboardFragment
NetworkDashboardFragment
PowerUsageSummary
修改isEligibleForIndexing()方法
修改getInjectionIndexableRawData()方法

3.屏蔽存储：

源码路径：package/apps/settings/src/com/android/settings/deviceinfo/storage/StorageDashboardFragment

核心修改：

  public static final BaseSearchIndexProvider SEARCH_INDEX_DATA_PROVIDER =
            new BaseSearchIndexProvider(R.xml.storage_dashboard_fragment) {
                @Override
                public boolean isPageSearchEnabled(Context context) {
                    return false; // 禁用搜索
                }
            };

4.屏蔽已连接的设备：

源码路径：package/apps/settings/src/com/android/settings/connecteddevice/ConnectedDeviceDashboardFragment

     */

            new BaseSearchIndexProvider(R.xml.connected_devices){
                @Override
                public boolean isPageSearchEnabled(Context context) {
                    return false; // 禁用搜索
                }
            };

            @Override

            }

            @Override

8.修改搜索Provider:

源码路径：package/apps/settings/src/com/android/settings/SettingsSearchIndexablesProvider

关键修改如下：

在getNonIndexableKeysFromProvider（）方法添加如下过滤:

 nonIndexableKeys.add(CategoryKey.CATEGORY_NETWORK);
        nonIndexableKeys.add(CategoryKey.CATEGORY_CONNECT);
        nonIndexableKeys.add(CategoryKey.CATEGORY_DEVICE);
        nonIndexableKeys.add(CategoryKey.CATEGORY_BATTERY);
        nonIndexableKeys.add(CategoryKey.CATEGORY_STORAGE);

                continue;
            }
            raw.key = dashboardFeatureProvider.getDashboardKeyForTile(tile);
            final CharSequence summary = tile.getSummary(context);
            raw.summaryOn = TextUtils.isEmpty(summary) ? null : summary.toString();
            raw.summaryOff = raw.summaryOn;
            raw.className = CATEGORY_KEY_TO_PARENT_MAP.get(tile.getCategory());
            rawList.add(raw);
        }
    }

    return rawList;
}

10.修改isEligibleForIndexing方法:

@VisibleForTesting
boolean isEligibleForIndexing(String packageName, Tile tile) {
    // 屏蔽特定 Tile
    if (tile.getCategory().equals(CategoryKey.CATEGORY_NETWORK) ||
            tile.getCategory().equals(CategoryKey.CATEGORY_CONNECT) ||
            tile.getCategory().equals(CategoryKey.CATEGORY_DEVICE) ||
            tile.getCategory().equals(CategoryKey.CATEGORY_BATTERY) ||
            tile.getCategory().equals(CategoryKey.CATEGORY_STORAGE)) {
        return false;
    }
    if (TextUtils.equals(packageName, tile.getPackageName())
            && tile instanceof ActivityTile) {
        // Skip Settings injected items because they should be indexed in the sub-pages.
        return false;
    }
    if (TextUtils.equals(tile.getCategory(), CategoryKey.CATEGORY_HOMEPAGE)) {
        // Skip homepage injected items since we would like to index their target activity.
        return false;
    }
    return true;
}

11.实现效果如下：

12.总结：

从上面的截图可以看到不管是搜索关键字还是具体的App，都没有出现网络和互联网、已连接的设备、存储、电池四个App的入口，基本上这几个App不会在Setting是搜索中出现，至此上面的问题得到解决。

找到问题需要多多查看源码，然后针对性进行修改, 打包镜像进行验证
在Setting中搜索前面几个App，基本上都不会出现
修改几个核心类和功能，然后进行调试验证
这些要屏蔽的App可以根据需求来实现，但是如果关键字搜索出来太多App入口，没必要全都屏蔽，这样修改的话后期如果不需要屏蔽改动太多，所以建议修改几个主要的App搜索入口即可.
