Android Action Bar SearchView NullPointerException adjustDropDownSizeAndPosition -

the problem occurs when interacting searchview or when activity searchview loads. when using seticonifiedbydefault(true) problem occurs after activity loads when interacting searchview, when using seticonifiedbydefault(false) problem occurs when activity loads.

the following error output in logcat:

java.lang.nullpointerexception @ android.widget.searchview.adjustdropdownsizeandposition(searchview.java:1244) 

here code:

exampleactivity.java

public boolean oncreateoptionsmenu(menu menu) {      getmenuinflater().inflate(r.menu.example, menu);      if(build.version.sdk_int >= build.version_codes.honeycomb) {          searchmanager manager = (searchmanager) getsystemservice(context.search_service);          searchview search = (searchview) menu.finditem(r.id.search).getactionview();          search.setsearchableinfo(manager.getsearchableinfo(getcomponentname()));          search.seticonifiedbydefault(true);          search.setonquerytextlistener(new onquerytextlistener() {               @override              public boolean onquerytextsubmit(string query) {                   // perform search                  return true;               }          });      }      return true;  } 

menu/example.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android">      <item         android:id="@+id/search"         android:title="search"         android:showasaction="ifroom"         android:actionviewclass="android.widget.searchview" />  </menu> 

xml/searchable.xml

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

the "search" string used in searchable.xml defined in values/strings.xml. searchable.xml file referenced correctly in activity tag in androidmanifest.xml:

<meta-data     android:name="android.app.default_searchable"     android:value="com.example.mainactivity" /> <meta-data     android:name="android.app.searchable"     android:resource="@xml/searchable" /> 

this problem caused styles being applied edittext in action bar searchview.

you can fix removing style have applied edittext such as:

res/values/styles.xml

<item name="android:edittextstyle">@style/editor</item> 

then go each edittext view in layout xml , apply style directly:

<edittext style="@style/editor" />
