Hi dev, I want to try to share another strange experience, which is when the font size in my SearchView component is too big, I thought it was easy, just define the properties in the xml layout, eh it turns out it's not that easy ferguso ... when I have implemented the function called android:textSize="60sp" but what happened? there was no change at all, here is my code case at that time.

<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"/>

The solution

Turns out, you can do that programmatically, like this.

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);

Or, you can also use alternative 1.

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));

Or, you can also use style, alternative 2.

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

then implement.

<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"/>

Done, good luck!
