在DataBaseHandler中无法应用于（java.lang.CharSequence）

Question

我在使用Android Studio创建SearchView小部件时遇到问题：

  DataBaseHandler中的

无法应用于（java.lang.CharSequence）

我的代码：

searchable.xml

<?xml version="1.0" encoding="utf-8"?>
<searchable xmlns:android="http://schemas.android.com/apk/res/android"
    android:label="@string/app_name"
    android:hint="search"
    android:searchSettingsDescription="search."


    android:searchSuggestIntentAction="android.intent.action.VIEW"
    android:searchSuggestSelection=" ?"
    android:searchSuggestThreshold="2" >

</searchable>

的AndroidManifest.xml

        <activity
            android:name="com.rifki.doaniatislam.AuteursActivity"
            android:label="@string/title_activity_auteurs"
            android:screenOrientation="portrait">
            <intent-filter>
                <action android:name="android.intent.action.SEARCH" />
            </intent-filter>

            <!-- Points to searchable activity -->
            <meta-data android:name="android.app.default_searchable"
                android:value=".AuteursActivity" />
            <meta-data android:name="android.app.default_searchable"
                android:value=".QuotesActivity" />

            <!-- Points to searchable meta data -->
            <meta-data android:name="android.app.searchable"
                android:resource="@xml/searchable"/>
        </activity>

menu_quotes.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android"

        searchView = (SearchView) MenuItemCompat.getActionView(searchItem);
        searchView.setQueryHint(getResources().getString(R.string.search));
        // Configure the search info and add any event listeners
