如何在 Android 工具栏的 SearchView 小部件中删除白色下划线 [英] How to remove white underline in a SearchView widget in Toolbar Android

问题描述

我在我的项目中使用工具栏搜索小部件.一切正常，但希望我完全坚持删除工具栏中搜索字段下方的下划线.我尝试了很多解决方案，但没有任何效果.以下是我尝试过的一些解决方案.

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.

要求去除图片中的白色下划线

Ist 解决方案:

//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);

    }

第二个解决方案:

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

上面的代码可以改变 EditText 的背景，但下划线仍然显示在 SearchBar 中的关闭图标下方.

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

我用于 SearchBar 小部件的完整代码如下:

    @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>

可能重复这个

推荐答案

试过如下

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

希望对你有帮助.
