因为我隐含的应用程序兼容我的searchview不工作了：

Process: com.laurenswuyts.witpa, PID: 26666

java.lang.NullPointerException: Attempt to invoke virtual method 'void android.support.v7.widget.SearchView.setSearchableInfo(android.app.SearchableInfo)' on a null object reference

所以nullpointer为searchview，而我有它：

@Override

public boolean onCreateOptionsMenu(Menu menu) {

MenuInflater inflater = getMenuInflater();

inflater.inflate(R.menu.event_main, menu);

// Get the SearchView and set the searchable configuration

// Associate searchable configuration with the SearchView

SearchManager searchManager =

(SearchManager) getSystemService(Context.SEARCH_SERVICE);

SearchView searchView =

(SearchView) menu.findItem(R.id.action_search).getActionView();

searchView.setSearchableInfo(

searchManager.getSearchableInfo(getComponentName()));

return super.onCreateOptionsMenu(menu);

}

在我的菜单我有这：

android:title="@string/action_search"

android:icon="@drawable/ic_action_search"

app:showAsAction="always"

android:actionViewClass="android.support.v7.widget.SearchView"/>

我不知道为什么它不工作，但发生了，因为我开始使用应用程序兼容21。

问候，
