How to remove white underline in a SearchView widget in Toolbar Android

Question

I am using the Toolbar search widget in my project. Everything works fine but expect the thing which I am completely stuck up with removing the underline below the search field in my toolbar. I have tried many solutions and nothing works out. Below are some of the solutions that I tried.

Requirement is to remove white underline in the image

Ist Solution:

//Removing underline

    int searchPlateId = searchView.getContext().getResources().getIdentifier("android:id/search_plate", null, null);
    View searchPlate = searchView.findViewById(searchPlateId);
    if (searchPlate!=null) {
        searchPlate.setBackgroundColor (Color.TRANSPARENT);
        int searchTextId = searchPlate.getContext ().getResources ().getIdentifier ("android:id/search_src_text", null, null);

    }

IInd Solution:

 EditText searchEdit = ((EditText)searchView.findViewById(android.support.v7.appcompat.R.id.search_src_text));
 searchEdit.setBackgroundColor(Color.TRANSPARENT);

The above code works to change the background of EditText but still underline is displaying below the close icon in SearchBar.

Complete code that I am using for SearchBar widget as follows:

    @Override
    public void onCreateOptionsMenu(Menu menu, MenuInflater infl) {
        super.onCreateOptionsMenu(menu, infl);
        MenuInflater inflater = getActivity().getMenuInflater();
        inflater.inflate(R.menu.action_search, menu);
        final SearchView searchView = (SearchView) MenuItemCompat
                .getActionView(menu.findItem(R.id.search));

        SearchManager searchManager = (SearchManager) getActivity ().getSystemService (getActivity ().SEARCH_SERVICE);
        searchView.setSearchableInfo (searchManager.getSearchableInfo (getActivity ().getComponentName ()));

        //changing edittext color
        EditText searchEdit = ((EditText)searchView.findViewById(android.support.v7.appcompat.R.id.search_src_text));
        searchEdit.setTextColor(Color.WHITE);
}

action_search.xml

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:compat="http://schemas.android.com/apk/res-auto">
    <item android:id="@+id/search"
        android:title="Search"
        android:icon="@drawable/abc_ic_search_api_mtrl_alpha"
        compat:showAsAction="ifRoom|collapseActionView"
        compat:actionViewClass="android.support.v7.widget.SearchView" />
</menu>

what do you do when the searchView has an Voice button ? i've tried to use the same trick with the search_voice_btn id but it's not works – Propagandize

Thanks a lot. In my case I set the Background drawable to null i.e. searchView.findViewById(android.support.v7.appcompat.R.id.search_plate)setBackground(null) – Jamshedpur

Not help me.Underline is stay any way – Atropos

The following answer should be the accepted answer instead of this. – Experiential

For AndroidX use: androidx.appcompat.R.id.search_plate – Forcer

Answer 2

If you are using SearchView then use for API below 21

android:queryBackground="@android:color/transparent"

you can use below code if you are using API 21 or more

app:queryBackground="@android:color/transparent"

Legality

FYI, this property is available from Api Level 21 onwards. – Gordie

try app:queryBackground="@android:color/transparent" =) – Latinism

app:queryBackground="@android:color/transparent" works properly on Api Level 21 instead of android:queryBackground="@android:color/transparent" – Curtsey

It doesn't work for me on API 29 :( I still see the underline. – Picard

TBH, it is NOT API LEVEL that makes decision, it is the VIEW type you use. For example, I use SearchView (not androidx.appcompat.widget.SearchView ) in API 28, then I should use android: prefix instead. – Jemine

Answer 3

Just add this line if you are using a v7 or androidx widget

app:queryBackground="@android:color/transparent"

Lyn

If 'app:' doesn't work try 'android:'. It worked for me. – Spurrier

Answer 4

Or you can do this through styles:

<style name="SearchViewMy" parent="Widget.AppCompat.Light.SearchView">
    <item name="submitBackground">@color/primaryColor</item>
    <item name="queryBackground">@color/primaryColor</item>
</style>

queryBackground is attribute for the query background. If you support voice search you may want to remove the line also under that mic button. Thats what submitBackground attribute is for.

Then of course apply the style to your theme.

<style name="Theme.App" parent="Theme.AppCompat.Light.NoActionBar.FullScreen">
    <item name="searchViewStyle">@style/SearchViewMy</item>
</style>

This is the best answer as it doesn't make assumptions about the view hierarchy implementation of the support library, which may change without notice. – Stanley

Indeed a best answer! Prefer this first before trying any other solution. – Dorren

Nope. Does not work – Creolacreole

Answer 5

For AndroidX I used this based on other answers here,

searchView.findViewById(androidx.appcompat.R.id.search_plate)
        .setBackgroundColor(Color.TRANSPARENT)

Awesome solution Thanks:) – Feat

Answer 6

if you want to remove the underline from SearchView, then just copy paste the below code to your SearchView. it works

 android:queryBackground="@null"

like this,

      <SearchView
                android:id="@+id/searchView"
                android:layout_width="match_parent"
                android:layout_height="100dp"
                android:queryBackground="@null"
                />

You can try using the below code, works like a charm for me.

View v = searchView.findViewById(android.support.v7.appcompat.R.id.search_plate);
    v.setBackgroundColor(ContextCompat.getColor(context,android.R.color.transparent));

Instead of ContextCompat.getColor... simply use Color.TRANSPARENT. – Antirachitic

Answer 8

The below piece of code works for me.

val searchView = menu?.findItem(R.id.action_search)?.actionView as SearchView
searchView.findViewById<View>(androidx.appcompat.R.id.search_plate).background = null

Answer 9

For androidx and kotlin:

        menuInflater.inflate(R.menu.conversation_list_screen_menu, menu)
        val searchItem = menu.findItem(R.id.action_search)
        searchView = searchItem.actionView as SearchView
        searchView?.findViewById<View>(androidx.appcompat.R.id.search_plate)?.setBackgroundColor(Color.TRANSPARENT)

Answer 10

The code for changing the background color of SearchView edit text is below

public static void setSearchViewEditTextBackgroundColor(Context context, SearchView searchView, int backgroundColor){
    int searchPlateId = context.getResources().getIdentifier("android:id/search_plate", null, null);
    ViewGroup viewGroup = (ViewGroup) searchView.findViewById(searchPlateId);
    viewGroup.setBackgroundColor(ComponentUtils.getColor(context, backgroundColor));
}

If your action bar background color is white then call the above method as follow.

setSearchViewEditTextBackgroundColor(this, searchView, R.color.white);

Now the underline from SearchView edit text will disappear.

Actually, this is the only answer that worked for me. An expanded explanation on why this works is available here – Alanealanine

Answer 11

First you should get the bottom line simply like this:

searchPlate = (View) findViewById(R.id.search_plate);

Then you should set background color to transparent like this:

searchPlate.setBackgroundColor(Color.TRANSPARENT);

This works perfectly for androidx.appcompat.widget.SearchView!
