There's a way to do this. The trick is to recover the ImageView using its identifier and setting a new image with <code>setImageResource()</code>. This solution is inspired on <a href="https://stackoverflow.com/questions/11085308/changing-the-background-drawable-of-the-searchview-widget">Changing the background drawable of the searchview widget</a>.

<pre><code>private SearchView searchbox;

private void customizeSearchbox() {
 setSearchHintIcon(R.drawable.new_search_icon);
}

private void setSearchHintIcon(int resourceId) {
 ImageView searchHintIcon = (ImageView) findViewById(searchbox, 
 "android:id/search_mag_icon");
 searchHintIcon.setImageResource(resourceId);
}

private View findViewById(View v, String id) {
 return v.findViewById(v.getContext().getResources().
 getIdentifier(id, null, null)); 
}
</code></pre>

blocks|key|226210|text|我也在努力解决这个问题，但是我不小心用上了“collapseActionView”，这就解决了它！我的menu.xml现在看起来像这样：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|226211|<menu+xmlns:android="http://schemas.android.com/apk/res/android">

I was struggling with this too but then I accidentaly used 'collapseActionView' and that fixed it!
My menu.xml looks like this now:

<pre><code>&lt;menu xmlns:android="http://schemas.android.com/apk/res/android"&gt;
&lt;item android:id="@+id/menu_search"
 android:title="@string/menu_search"

 android:actionViewClass="android.widget.SearchView"
 android:icon="@android:drawable/ic_menu_search" /&gt; 
&lt;/menu&gt;
</code></pre>

The downside of this is that on tablets the SearchView will appear on the left side of the ActionBar instead of where the searchicon is, but I don't mind that.

I've found another way to change the search icon which goes in the same line as Diego Pino's answer but straight in <code>onPrepareOptionsMenu</code>.

In your menu.xml (same as before)

<pre><code>&lt;menu xmlns:android="http://schemas.android.com/apk/res/android"&gt;
&lt;item android:id="@+id/action_search"
 android:icon="@drawable/ic_action_fav"
 android:title="@string/action_websearch"
 android:showAsAction="always|never"
 android:actionViewClass="android.widget.SearchView" /&gt;
&lt;/menu&gt;
</code></pre>

In your activity:

<pre><code>@Override
public boolean onPrepareOptionsMenu(Menu menu) {
 MenuItem searchViewMenuItem = menu.findItem(R.id.action_search); 
 mSearchView = (SearchView) searchViewMenuItem.getActionView();
 int searchImgId = getResources().getIdentifier("android:id/search_button", null, null);
 ImageView v = (ImageView) mSearchView.findViewById(searchImgId);
 v.setImageResource(R.drawable.your_new_icon); 
 mSearchView.setOnQueryTextListener(this);
 return super.onPrepareOptionsMenu(menu);
}
</code></pre>

I followed the example for changing the edittext in this <a href="https://stackoverflow.com/questions/11085308/changing-the-background-drawable-of-the-searchview-widget/11669808#11669808">example</a>.

You should be able to do this for all icons/backgrounds in your <code>SearchView</code>, to find the right ID you can check <a href="http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android/4.0.4_r1.2/android/widget/SearchView.java/#248" rel="noreferrer">here</a>.

Hope this helps someone else as well!

UPDATE November 2017:

Since this answer android has been updated with the possibility of changing the search icon through the XML. 

If you target anything below android v21 you can use: 

<pre><code>&lt;android.support.v7.widget.SearchView
 android:layout_width="wrap_content"
 android:layout_height="match_parent"
 app:searchIcon="@drawable/ic_search_white_24dp"
 app:closeIcon="@drawable/ic_clear_white_24dp" /&gt;
</code></pre>

Or v21 and later:

<pre><code>&lt;SearchView
 android:layout_width="wrap_content"
 android:layout_height="match_parent"
 android:searchIcon="@drawable/ic_search_white_24dp"
 android:closeIcon="@drawable/ic_clear_white_24dp" /&gt;
</code></pre>

And there are even more options:

<pre><code>closeIcon
commitIcon
goIcon
searchHintIcon
searchIcon
voiceIcon
</code></pre>

My solution:
Use two menu xml files. In one of the xmls the menu item has an actionView and in the other one no. Initially inflate the collapsed menu and when the menu item is clicked, invalidate the menu and inflate the expanded menu xml and make sure you call setIconified(false);

<pre><code>@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater)
{
 if(!mShowSearchView)
 {
 inflater.inflate(R.menu.menu_collapsed, menu);
 }
 else
 {
 inflater.inflate(R.menu.menu_expanded, menu);
 MenuItem searchItem = menu.findItem(R.id.action_search);
 SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem);
 searchView.setIconified(false);
 searchView.setOnCloseListener(new OnCloseListener()
 {
 @Override
 public boolean onClose()
 {
 mShowSearchView = false;
 ActivityCompat.invalidateOptionsMenu(getActivity());
 return false;
 }
 });
 }
 super.onCreateOptionsMenu(menu, inflater);
}

@Override
public boolean onOptionsItemSelected(MenuItem item)
{
 if (item.getItemId() == R.id.action_filter)
 {
 menu.showMenu();
 }
 else if (item.getItemId() == R.id.action_search)
 {
 mShowSearchView = true;
 ActivityCompat.invalidateOptionsMenu(getActivity());
 }
 return super.onOptionsItemSelected(item);
}

I use the AppCompat library. Yes, specifying <code>android:icon="@drawable/search_icon_png"</code> doesnt work.
So i looked into the source code of @style/Theme.AppCompat and found the icon that android uses. 

<pre><code>&lt;item name="searchViewSearchIcon"&gt;@drawable/abc_ic_search&lt;/item&gt;
</code></pre>

So if you rename your search icon inside your drawables to <code>abc_ic_search.png</code>, this icon is rendered as its found in your app drawable first, rather than the appcompat drawable folder.
Works for me :)

Using this approach you can customize the close and clear icons for the search widget as well.

stopHint.setSpan(new ImageSpan(searchIcon), 1, 2, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

Just name your icon the same name as the icon that is used by the search view. When it compiles it takes the resource in the project over the icon in the library.

Nice answer from @just_user

For my case, since I am using the appcompat v7 library for the SearchView + ActionBar, i modified his solution a bit to make it compatible to my project, it should work so as long as you did not modify anything when you added appcompat v7 as library

XML:

<pre><code>&lt;menu xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:metrodeal="http://schemas.android.com/apk/res-auto" &gt;


 &lt;item
 android:id="@+id/main_menu_action_search"
 android:orderInCategory="100"
 android:title="@string/search"
 metrodeal:showAsAction="always"
 metrodeal:actionViewClass="android.support.v7.widget.SearchView" 
 android:icon="@drawable/search_btn"/&gt;

&lt;/menu&gt;
</code></pre>

Java code:

<pre><code>@Override

Excuse for the very big icon (I have not resized the icon just yet), but it should work as it is.

There are three magnifying glass icons. two of them are shown when IconizedByDefault is true(one which is shown before pressing and one is shown in the "hint") and one is shown all the time when IconizedByDefault is false. all the fields are private so the way to get them is by their xml id. (most of the code is mentioned separately in other answers in this post already)

when IconizedByDefault is true change the icon in the hint (which is seen only after pressing the icon) by :

<pre><code>mSearchSrcTextView = (SearchAutoComplete)findViewById(R.id.search_src_text);
</code></pre>

then do the same as in the android source code:

<pre><code>final int textSize = (int) (mSearchSrcTextView.getTextSize() * 1.25);
 newSearchIconDrawable.setBounds(0, 0, textSize, textSize);

 final SpannableStringBuilder ssb = new SpannableStringBuilder(" ");
 ssb.setSpan(new ImageSpan(newSearchIconDrawable), 1, 2, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
 ssb.append(hintText);
</code></pre>

mSearchHintIcon was replaced with newSearchIconDrawable which is your new search icon. 
Then set the hint with

<pre><code>mSearchSrcTextView.setHint(ssb); 
</code></pre>

The other 2 icons are in an <code>ImageView</code>, which can be found by their Id.
for the icon when searchview is closed (when iconizedByDefault is true) do:

<pre><code>mSearchButton = (ImageView) findViewById(R.id.search_button);
</code></pre>

and for the one that always appears (if iconizedByDefault is false)

<pre><code>mCollapsedIcon = (ImageView) findViewById(R.id.search_mag_icon);
</code></pre>

This works with Material Design (MaterialComponents theme) and BottomAppBar.

If you are using androidx library, for example:

<pre><code> &lt;item
 android:id="@+id/sv"
 android:title="@string/search"
 app:actionViewClass="androidx.appcompat.widget.SearchView"
 app:showAsAction="always" /&gt;
</code></pre>

You can create a method and invoke it from wherever you want:

<pre><code> /**
 * Set SearchView Icon
 * @param i Drawable icon
 */
private void setSVIcon(int i) {
 ImageView iv = searchView.findViewById(androidx.appcompat.R.id.search_button);
 iv.setImageDrawable(ResourcesCompat.getDrawable(getResources(), i, null));
}
</code></pre>

Usage example:

<pre><code>@Override
public boolean onCreateOptionsMenu(Menu menu) {
 getMenuInflater().inflate(m, menu);
 MenuItem mn = menu.findItem(R.id.sv);
 if (mn != null) {
 searchview = (SearchView) mn.getActionView();
 setSVIcon(R.drawable.ic_sr);
 }

I'm having a bit of trouble customizing the search icon in the SearchView. On my point of view, the icon can be changed in the Item attributes, right? Just check the code bellow..

Can someone tell me what I'm doing wrong? 

This is the menu I'm using, with my custom search icon icn_lupa. But when I run the app, I always get the default search icon...

<pre><code>&lt;menu xmlns:android="http://schemas.android.com/apk/res/android"&gt;
&lt;item android:id="@+id/menu_search"
 android:title="@string/menu_search"
 android:icon="@drawable/icn_lupa"
 android:showAsAction="always"
 android:actionViewClass="android.widget.SearchView" /&gt;
&lt;/menu&gt;
</code></pre>

Thanks in advance.
