Text input in SearchView doesn't show

I noticed a couple days ago that inputting text in my

SearchView
doesn't show up. Maybe this problem started longer ago and I hadn't noticed it, but I know that everything was working well when I first set up search functionality.

Here is a screenshot (I have already entered text, and you can see that it is not showing):

enter image description here

I have already tried to change the colour of the text on the
SearchView
, with this SO question, and I've also tried changing the text colour in my searchable configuration XML file. After I found that none of these work, I undid my changes so that you can see the code I currently have below:

MainActivity.java

@Override
public boolean onCreateOptionsMenu(Menu) {

...

// Associate searchable configuration with the SearchView
SearchManager searchManager = (SearchManager) getSystemService(SEARCH_SERVICE);
MenuItem searchMenuItem = menu.findItem(R.id.action_search);
SearchView searchView = (SearchView) searchMenuItem.getActionView();
searchView.setSearchableInfo(searchManager.getSearchableInfo(new ComponentName(this, SearchResultsActivity.class)));
// Note: getSearchableInfo(getComponentName()) will not work on all flavours
// because of a difference in app IDs

}


Note that I've used
new ComponentName(...)
instead of
getSearchableInfo(getComponentName())
since I use different package names in my different flavours.

The activity above is where the
SearchView
is displayed. The results are shown in another activity.

searchable.xml

<searchable xmlns:android="http://schemas.android.com/apk/res/android"
android:label="@string/app_name"
android:hint="@string/search_hint" />


AndroidManifest.xml

...

<activity
android:name=".ui.MainActivity"
android:label="@string/title_activity_main"
android:theme="@style/AppTheme">
<meta-data
android:name="android.app.default_searchable"

<action android:name="android.intent.action.SEARCH" />
</intent-filter>

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

...


styles.xml (the activity containing the
SearchView
uses
AppTheme.NavDrawer
)

...

<style name="Base.AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="android:windowNoTitle">true</item>
<item name="windowActionBar">false</item>

<item name="colorAccent">@color/theme_accent</item>
</style>

<style name="AppTheme.NavDrawer">
<item name="android:windowBackground">@color/window_background</item>

....


activity_main_filterable.xml (the layout that my activity uses)

<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/drawerLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true" >

<include layout="@layout/activity_main_content" />

<include layout="@layout/navdrawer"
android:id="@+id/navigationView" />

<include layout="@layout/filter_drawer"
android:id="@+id/filter_drawer" />

</android.support.v4.widget.DrawerLayout>


activity_main_content.xml

<RelativeLayout

android:layout_width="match_parent"
android:layout_height="match_parent">

<android.support.design.widget.CoordinatorLayout

android:layout_height="match_parent"
android:layout_above="@+id/adView">
<android.support.design.widget.AppBarLayout
android:fitsSystemWindows="true"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"

android:layout_height="wrap_content"
android:layout_width="match_parent"
app:layout_scrollFlags="scroll|enterAlways"/>
<include layout="@layout/blank" /> <!-- This is to prevent bugs -->
</android.support.design.widget.AppBarLayout>

<include layout="@layout/fragment_misc_no_results"
android:id="@+id/fragment_no_results"/>

<android.support.v7.widget.RecyclerView
android:id="@+id/recyclerView"
style="@style/AppTheme.RecyclerView.StandardList"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_behavior="@string/appbar_scrolling_view_behavior" />
</android.support.design.widget.CoordinatorLayout>

<com.google.android.gms.ads.AdView
android:id="@+id/adView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
ads:adSize="SMART_BANNER"
ads:adUnitId="@string/banner_ad_unit_id" />
</RelativeLayout>


Any ideas on what might be going on or how I should solve it?

Answer

I had the same issue, and for me it was because I had set my toolbar height to wrap_content. Try giving it a size, like this:

<android.support.v7.widget.Toolbar
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    app:theme="@style/ToolbarTheme"
    app:popupTheme="@style/AppTheme.PopupOverlay"
    app:layout_scrollFlags="scroll|enterAlways"
    />
