Change searchView threshold

I have a little problem: I have a searchView which works with the suggestionAdapter. The problem is that the searchView start to display results from 2 characters. I have however set the threshold to 1 in the searchable.xml + in the code but it doesn't works.The magic here is if I set the threshold to 5 it works...

Searchable.xml:

<searchable xmlns:android="http://schemas.android.com/apk/res/android"
    android:label="@string/city_list_search"
    android:hint="@string/city_list_search"
    android:searchSuggestThreshold="1">
</searchable>

Manifest.xml:

<activity
        android:name=".activities.HomeActivity"
        android:launchMode="singleTop"
        android:screenOrientation="portrait"
        android:windowSoftInputMode="adjustResize" >
        <intent-filter>
            <action android:name="android.intent.action.VIEW" />

            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.BROWSABLE" />
            <action android:name="android.intent.action.SEARCH" />

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

        </intent-filter>
    </activity>

My fragment where I also set the threshold to 1:

AutoCompleteTextView search_text = (AutoCompleteTextView) mSearchView.findViewById(mSearchView.getContext().getResources().getIdentifier("android:id/search_src_text", null, null));
    search_text.setThreshold(1);

    mSearchView.setIconifiedByDefault(false);
    mSearchView.setSearchableInfo(mSearchManager.getSearchableInfo(getActivity().getComponentName()));

Where I set the custom adapter: (called in : public boolean onQueryTextChange(String newText))

public void updateSearchResults() {
    mSearchView.setSuggestionsAdapter(new CityListSearchResultAdapter(root.getContext(), mCursor));
}

According to documentation, you have to declare the searchSuggestAutority in your searchable :

android:searchSuggestAuthority="com.example.MyCustomSuggestionProvider"

http://developer.android.com/guide/topics/search/adding-custom-suggestions.html

if you really want to use suggestionsAdapter to provide data, don't call setSuggestionsAdapter in updateSearchResults but in onCreate, just update your cursor. You can also have a look to https://gist.github.com/slightfoot/5514856

You can use Appcompact activity with v7 Searchview. Use as follows to change the threshold,

AutoCompleteTextView autoCompleteTextView = (AutoCompleteTextView) searchView.findViewById(android.support.v7.appcompat.R.id.search_src_text);
autoCompleteTextView.setThreshold(0);
