How to delete or change the searchview icon inside the SearchView actionBar?

Question

How to remove or change the search view icon inside the edittext? I am using the Appcompat library.

I used the below code to modify and remove but it's not working:

SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
        searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
    View search_mag_icon = (View)searchView.findViewById(android.support.v7.appcompat.R.id.search_mag_icon);
        search_mag_icon.setBackgroundResource(R.drawable.ic_stub);
        //search_mag_icon.setVisibility(View.GONE);

Answer 1

Finally found the solution. Try the following:

try {
    Field mDrawable = SearchView.class.getDeclaredField("mSearchHintIcon");
    mDrawable.setAccessible(true);
    Drawable drawable =  (Drawable)mDrawable.get(your search view here);
    drawable.setAlpha(0);
} catch (Exception e) {
    e.printStackTrace();
}

Per the AppCompat v21 blog post, you can provide a custom style for your SearchView, overriding things such as the search icon:

<style name="Theme.MyTheme" parent="Theme.AppCompat">
    <item name="searchViewStyle">@style/MySearchViewStyle</item>
</style>
<style name="MySearchViewStyle" parent="Widget.AppCompat.SearchView">
    <!-- Search button icon -->
    <item name="searchIcon">@drawable/custom_search_icon</item>
</style>

Answer 3

no a good idea use private method as SearchView.class.getDeclaredField("mSearchHintIcon");

<item android:id="@+id/menu_search"
        android:icon="@drawable/action_search"
        app:actionLayout="@layout/xx_layout"
        app:showAsAction="always"/>

and in xx_layout:

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.SearchView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/search_view"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:searchHintIcon="@null"
    android:iconifiedByDefault="true" />
