How to set SearchView TextSize?

I have a SearchView inside a LinearLayout and I'm trying to set a different TextSize for it (the SearchView) but when setting android:textSize="60sp" for example, nothing happens.

This is my code:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
          android:layout_width="fill_parent"
          android:layout_height="wrap_content"
          android:orientation="vertical"
          android:padding="2dp">
<SearchView
        android:id="@+id/searchView"
        android:layout_width="350dp"
        android:textSize="60sp"
        android:layout_height="80dp"
        android:layout_marginTop="15dp"/>
<ListView
        android:id="@+id/search_results"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"/>

Does anyone know how to modify the TextSize of the control?

You could do these using code

SearchView searchView = new SearchView(context);
LinearLayout linearLayout1 = (LinearLayout) searchView.getChildAt(0);
LinearLayout linearLayout2 = (LinearLayout) linearLayout1.getChildAt(2);
LinearLayout linearLayout3 = (LinearLayout) linearLayout2.getChildAt(1);
AutoCompleteTextView autoComplete = (AutoCompleteTextView) linearLayout3.getChildAt(0);
autoComplete.setTextSize(60);

Here is another solution

SearchView searchView = new SearchView(context);
AutoCompleteTextView search_text = (AutoCompleteTextView) searchView.findViewById(searchView.getContext().getResources().getIdentifier("android:id/search_src_text", null, null));
search_text.setTextColor(Color.WHITE);
search_text.setTextSize(TypedValue.COMPLEX_UNIT_PX, getResources().getDimensionPixelSize(R.dimen.text_small));

You can achieve this using a theme:

in styles.xml

<style name="AppSearchView" parent="Widget.AppCompat.SearchView" >
        <item name="android:textSize">60sp</item>
    </style>

And using a SearchView

<android.support.v7.widget.SearchView
            android:id="@+id/searchView"
            android:layout_width="350dp"
            app:theme="@style/AppSearchView"
            android:layout_height="80dp"
            android:layout_marginTop="15dp"/>

When using ActionBarSherlock you have to do this:

    AutoCompleteTextView searchTextView = (AutoCompleteTextView) searchView.findViewById(R.id.abs__search_src_text);
    searchTextView.setTextColor(getResources().getColor(R.color.search_text_color));

Sneg

Check this answer Can we limit the number of character in edittext of SearchView in Android?. It uses SearchView.OnQueryTextListener in order to check if exceeded the limit.

Though AutoCompleteTextView is superclass of SearchAutoComplete, SearchView use SearchAutoComplete rather than AutoCompleteTextView. use it and do more.

SearchView searchView=...;
SearchView.SearchAutoComplete autoComplete= searchView.findViewById(android.support.v7.appcompat.R.id.search_src_text);
float textSpSize=10.f;
if (autoComplete!=null){
    autoComplete.setTextSize(textSpSize);
   }
