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

Question

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

Answer 1

Once try as follows

View v = searchView.findViewById(android.support.v7.appcompat.R.id.search_plate);
v.setBackgroundColor(Color.parseColor("here give actionbar color code"));

Hope this will helps you.

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"

Answer 3

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>

Answer 4

Just add this line if you are using a v7 widget

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

Answer 5

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));

Answer 6

For AndroidX I used this based on other answers here,

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

Answer 7

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.

Answer 8

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!

Answer 9

The following solved the problem perfectly for me:

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