SearchView getActionView returning null

Question

This was working a few days ago, but suddenly it stopped. I only want to use the action bar search widget when certain fragment is visible.

Now I'm unable to get the SearchView, now getActionView always returns null.

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="@string/search_for_places">
</searchable>

Manifest.xml

<activity
    android:name=".ui.activities.MainActivity"
    android:launchMode="singleTop">
    <intent-filter>
        <action android:name="android.intent.action.MAIN"/>
        <category android:name="android.intent.category.LAUNCHER"/>
        <action android:name="android.intent.action.SEARCH"/>
    </intent-filter>
    <meta-data
        android:name="android.app.searchable"
        android:resource="@xml/searchable"/>
    <meta-data
    android:name="android.app.default_searchable"
    android:value=".ui.activities.MainActivity" />
</activity>

menu.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:myapp="http://schemas.android.com/apk/res-auto">
    <item
        android:id="@+id/action_search_place"
        android:icon="@drawable/ic_2_action_search"
        android:orderInCategory="1"
        android:title="@string/title_search"
        myapp:showAsAction="collapseActionView|ifRoom"
        myapp:actionViewClass="android.support.v7.widget.SearchView"/>
</menu>

The fragment

...
setHasOptionsMenu(true);
...



@Override
public void onCreateOptionsMenu(final Menu menu, final MenuInflater inflater) {
    inflater.inflate(R.menu.menu, menu);
    MenuItem searchItem = menu.findItem(R.id.action_search_place);
    mSearchView = (SearchView) MenuItemCompat.getActionView(searchItem);

    SearchManager searchManager = (SearchManager) getBaseActivity().getSystemService(Context.SEARCH_SERVICE);
    if (mSearchView != null) {
        mSearchView.setSearchableInfo(searchManager.getSearchableInfo(getActivity().getComponentName()));
        mSearchView.setIconifiedByDefault(true);
        mSearchView.setOnQueryTextListener(this);
    }
    super.onCreateOptionsMenu(menu, inflater);
}

Answer 1

I had the same problem because in my menu I used: android:actionViewClass="android.widget.SearchView" as per the google documentation.

Well it turns out that if I'm using AppCompatActivity I should use app:actionViewClass="android.widget.SearchView" instead.

Hope this helps someone.

If you're using proguard this is the possible answer: https://code.google.com/p/android/issues/detail?id=58508

In short, add below line to your proguard config file proguard-rules.pro.

-keep class android.support.v7.widget.SearchView { *; }

Answer 3

Today I had the same problem and I think I solved it. It turns out I did couple of things that were not exactly as per the ActionBarCompat contract:

• Each activity that uses the ActionBarCompat should extend ActionBarActivity instead of FragmentActivity directly
• Each activity that uses the ActionBarCompat should declare its theme as inheriting from the ActionBarCompat themes.

Both of those I found watching the explanation video from Google.

Now my searchView is not null anymore.

Answer 4

I fixed it: in the menu xml, I used the app namespace

For users of androidx libraries:

    app:showAsAction="collapseActionView|always"
    app:actionViewClass="androidx.appcompat.widget.SearchView"

For users of the older support libraries:

    app:showAsAction="collapseActionView|always"
    app:actionViewClass="android.support.v7.widget.SearchView"

The Android tutorial, https://developer.android.com/training/search/setup.html, uses the framework SearchView rather than the androidx/support library one, and so it uses android:showAs and android:actionView

Changing to import android.support.v7.widget.SearchView helped me
