Android Action Bar SearchView NullPointerException adjustDropDownSizeAndPosition

StackOverflow https://stackoverflow.com/questions/22295138

Question

The problem occurs when interacting with the SearchView or when the activity with the Searchview loads. When using setIconifiedByDefault(true) the problem occurs after the activity loads when interacting with the SearchView, but when using setIconifiedByDefault(false) the problem occurs when the activity loads.

The following error is output in LogCat:

java.lang.NullPointerException
at android.widget.SearchView.adjustDropDownSizeAndPosition(SearchView.java:1244)

Here is the 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 is defined in values/strings.xml. Also the searchable.xml file is referenced correctly in the 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" />

Solution

This problem is caused by styles being applied to the EditText in the action bar SearchView.

You can fix this by removing any style you have applied to EditText such as:

res/values/styles.xml

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

Then go to each EditText view in your layout XML and apply the style directly:

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