Question

Answer 1

I have a simple way to do this without using an autocomplete textview, just put a simple list adapter which contain a ArrayList(itemArrayList) of items, to suggest with search view.Set the adapter to your SearchAutoComplete and auto complete feature will work below is my code.With this, you don't have to use an extra Layout.

 @Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);

MenuItem searchItem = menu.findItem(R.id.search);
SearchView mSearchView = (SearchView) MenuItemCompat.getActionView(searchItem);

SearchAutoComplete searchAutoComplete = (SearchAutoComplete)     mSearchView.findViewById(android.support.v7.appcompat.R.id.search_src_text);
searchAutoComplete.setTextColor(Color.WHITE);

ArrayAdapter adapter = new ArrayAdapter(this,
android.R.layout.simple_dropdown_item_1line, itemArrayList);
searchAutoComplete.setAdapter(adapter);

SearchManager searchManager =
(SearchManager) getSystemService(this.SEARCH_SERVICE);
mSearchView.setSearchableInfo(
searchManager.getSearchableInfo(getComponentName()));
return true;
}

Clicking the suggested item the item should appear on the search view so add the below code just after you set your adapter to searchAutoComplete inside the onCreateOptionmenu(...) method.

@Override
public void onItemClick(AdapterView parent, View view, int position,
long id) {
// TODO Auto-generated method stub

String searchString=(String)parent.getItemAtPosition(position);
searchAutoComplete.setText(""+searchString);
Toast.makeText(MainActivity.this, "you clicked "+searchString, Toast.LENGTH_LONG).show();

}
});
