我正在尝试将搜索建议更改为“浅色主题”。 我正在使用 appcompat-v7:22.2.0 库并阅读有关 new feature 的信息用于自定义搜索 View 小部件 (android.support.v7.widget.SearchView)。
第一个尝试部分
工具栏
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
android:minHeight="?attr/actionBarSize"
app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar" />
主题
<style name="Main.Theme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorPrimary">@color/red</item>
<item name="colorPrimaryDark">@color/red_dark</item>
<item name="searchViewStyle">@style/Main.Theme.SearchView</item>
</style>
SearchView 主题
<style name="Main.Theme.SearchView" parent="Widget.AppCompat.Light.SearchView">
<item name="voiceIcon">@mipmap/test_icon</item>
</style>
这样我就无法影响搜索 View 。为了测试它，我正在更改搜索 View 中的语音图标，它并没有改变默认设置。
第二个尝试部分
第二次尝试是覆盖工具栏中的覆盖主题:
叠加主题
<style name="Main.Theme.Overlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar">
<item name="searchViewStyle">@style/Main.Theme.SearchView</item>
</style>
这样我得到了一些反馈，但我失去了“ Material 设计”，特别是我有“旧”提示图标并且它带有下划线。 我的最终目标是更改搜索建议行背景:
建议行布局
<item name="suggestionRowLayout">@layout/my_custom_layout</item>
我觉得我离完成这个还很远……你能帮我吗？
最佳答案
这就是我使用自己的搜索建议的方式...
这是我的 CountriesFragment 文件，它只在建议中显示所有国家名称。
这里的技巧是我提供自定义 View 以显示建议列表。
public class CountriesFragment extends Fragment {
private boolean mSearchCheck;

这里是 hint_row.xml
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"

android:gravity="center_vertical"
android:background="@color/nliveo_green_colorPrimaryDark"
android:textColor="@color/nliveo_white"
android:paddingLeft="15dp"
android:paddingRight="15dp"
android:minHeight="?android:attr/listPreferredItemHeightSmall"
android:elevation="3dp"
android:alpha="0.7" />
具有 SearchView 的简单菜单文件。 menu.xml
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="@+id/menu_search"
app:actionViewClass="android.support.v7.widget.SearchView"
android:icon="@mipmap/ic_search_white_24dp"
app:showAsAction="ifRoom|collapseActionView"
android:title="@string/search"/>
<item
android:id="@+id/menu_add"
android:icon="@mipmap/ic_add_white_24dp"
app:showAsAction="ifRoom"
android:title="@string/add"/>
</menu>
