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>

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

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 3

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

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

Answer 4

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 5

For AndroidX I used this based on other answers here,

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

Answer 6

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 7

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"
                />

Answer 8

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 9

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 10

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 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!
