How to set SearchView TextSize?

问题

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?

回答1:

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));

回答4:

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);
   }

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.
