I has create an activity for search something.
but I want search view is searching status when I start this activity.

So..... like this, I create search view from option menu. but  setIconified set value false for set first open activity search view is open .

public void onCreate(Bundle savedInstanceState) {



 super.onCreate(savedInstanceState);
 setContentView(R.layout.xxx.xml)
 configActionBar(); 
 loadData();

 if (mSearchView != null && mSearchView.isIconified()) {
            mSearchView.setIconified(false);
 }



}


public boolean onCreateOptionsMenu(Menu menu) {

 getSupportMenuInflater().inflate(R.menu.search_button, menu);
 mSearchView = (SearchView) menu.findItem(R.id.search).getActionView();
 return super.onCreateOptionsMenu(menu);



}
