有人知道如何更改appcompat SearchView的文字颜色吗?我花了2个小时从SO那里尝试了几个建议,但都没有。

这是我的代码:

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:espacios="http://schemas.android.com/apk/res-auto" >

    <item
        android:id="@+id/layer_switcher_button"
        android:icon="@drawable/b_categorias"
        android:title="@string/menu_layer_switcher_title"
        espacios:showAsAction="ifRoom|collapseActionView"/>
    <item
        android:id="@+id/action_search"
        android:icon="@drawable/b_buscar"
        android:title="@string/menu_search_title"
        espacios:actionViewClass="android.support.v7.widget.SearchView"
        espacios:showAsAction="ifRoom|collapseActionView"/>

</menu>

在我的活动中,我有这个:

public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.main, menu);

    menuItem layerSwitcher = menu.findItem(R.id.layer_switcher_button);
    layerSwitcher.setOnMenuItemClickListener(new OnMenuItemClickListener() {

        @Override
        public boolean onMenuItemClick(MenuItem item) {
        onLayerSwitcherButtonClicked();
            return false;
        }
    });

    MenuItem searchItem = menu.findItem(R.id.action_search);
    SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem);

    LinearLayout ll = (LinearLayout) searchView.getChildAt(0);
    TextView textView = (TextView) ll.getChildAt(0);

    textView.setTextColor(R.color.white);
}

SearchView searchView = new SearchView(getContext());
SearchView.SearchAutoComplete theTextArea = (SearchView.SearchAutoComplete)searchView.findViewById(R.id.search_src_text);
theTextArea.setTextColor(Color.WHITE);//or any color that you want

SearchView对象从LinearLayout延伸,因此它包含其他视图。诀窍是找到包含提示文本的视图并以编程方式更改颜色。通过遍历视图层次结构,您可以找到包含提示文本的小部件:

// get your SearchView with its id
SearchView searchView = (SearchView) menu.findItem(R.id.search).getActionView();
// traverse the view to the widget containing the hint text
LinearLayout ll = (LinearLayout)searchView.getChildAt(0);
LinearLayout ll2 = (LinearLayout)ll.getChildAt(2);
LinearLayout ll3 = (LinearLayout)ll2.getChildAt(1);
SearchView.SearchAutoComplete autoComplete = (SearchView.SearchAutoComplete)ll3.getChildAt(0);
// set the hint text color
autoComplete.setHintTextColor(getResources().getColor(Color.WHITE));
// set the text color
autoComplete.setTextColor(Color.BLUE);

此方法适用于任何主题。此外,您可以更改SearchView层次结构中其他小部件的外观,例如保存搜索查询的EditText

这些答案都不适合我。最终工作的是在工具栏上设置主题并在那里指定textColorHint。

主题(在styles.xml中):

 <style name="ToolbarTheme">
    <item name="android:textColorHint">@color/white_opacity_60</item>
</style>

工具栏(在任何布局中)

<android.support.v7.widget.Toolbar 
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/ToolbarTheme" />

这是有效的,因为当您将主题设置为ViewGroup时,其属性也会应用于ViewGroup的所有子视图。这是主题和风格之间的差异之一:)

可以使用appcompat v7库自定义searchview。我使用了appcompat v7库并为其定义了自定义样式。  在drawable文件夹中放入bottom_border.xml文件,如下所示:

 <?xml version="1.0" encoding="utf-8"?>
 <layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
 <item>
  <shape >
      <solid android:color="@color/blue_color" />
  </shape>
  </item>
 <item android:bottom="0.8dp"
  android:left="0.8dp"
  android:right="0.8dp">
  <shape >
      <solid android:color="@color/background_color" />
  </shape>
 </item>

 <!-- draw another block to cut-off the left and right bars -->
 <item android:bottom="2.0dp">
  <shape >
      <solid android:color="@color/main_accent" />
  </shape>
  </item>
 </layer-list>

在值文件夹styles_myactionbartheme.xml中:

  <?xml version="1.0" encoding="utf-8"?>
  <resources>
  <style name="AppnewTheme" parent="Theme.AppCompat.Light">
    <item name="android:windowBackground">@color/background</item>
    <item name="android:actionBarStyle">@style/ActionBar</item>
    <item name="android:actionBarWidgetTheme">@style/ActionBarWidget</item>
  </style> 
  <!-- Actionbar Theme -->
  <style name="ActionBar" parent="Widget.AppCompat.Light.ActionBar.Solid.Inverse">
    <item name="android:background">@color/main_accent</item>
    <!-- <item name="android:icon">@drawable/abc_ic_ab_back_holo_light</item> -->
  </style> 
  <style name="ActionBarWidget" parent="Theme.AppCompat.Light">
    <!-- SearchView customization-->
     <!-- Changing the small search icon when the view is expanded -->
    <!-- <item name="searchViewSearchIcon">@drawable/ic_action_search</item> -->
     <!-- Changing the cross icon to erase typed text -->
  <!--   <item name="searchViewCloseIcon">@drawable/ic_action_remove</item> -->
     <!-- Styling the background of the text field, i.e. blue bracket -->
    <item name="searchViewTextField">@drawable/bottom_border</item>
     <!-- Styling the text view that displays the typed text query -->
    <item name="searchViewAutoCompleteTextView">@style/AutoCompleteTextView</item>        
  </style>

 <style name="AutoCompleteTextView" parent="Widget.AppCompat.Light.AutoCompleteTextView">
    <item name="android:textColor">@color/text_color</item>
  <!--   <item name="android:textCursorDrawable">@null</item> -->
    <!-- <item name="android:textColorHighlight">@color/search_view_selected_text</item> -->
 </style>
 </resources>

我定义了custommenu.xml文件以显示菜单:

  <menu xmlns:android="http://schemas.android.com/apk/res/android"
     xmlns:com.example.actionbartheme="http://schemas.android.com/apk/res-auto" >  

  <item android:id="@+id/search"
      android:title="@string/search_title"
      android:icon="@drawable/search_buttonn"
      com.example.actionbartheme:showAsAction="ifRoom|collapseActionView"
      com.example.actionbartheme:actionViewClass="android.support.v7.widget.SearchView"/>        
  </menu>

您的活动应该扩展ActionBarActivity而不是Activity。    这是onCreateOptionsMenu方法。

  @Override
  public boolean onCreateOptionsMenu(Menu menu) 
  {
      // Inflate the menu; this adds items to the action bar if it is present.
      MenuInflater inflater = getMenuInflater();
      inflater.inflate(R.menu.custommenu, menu);
  }

在清单文件中:

  <application
      android:allowBackup="true"
      android:icon="@drawable/ic_launcher"
      android:label="@string/app_name"
      android:theme="@style/AppnewTheme" >

我已经创建了 kotlin 扩展函数

提示颜色:

fun SearchView.setHintTextColor(@ColorInt color: Int) {
    findViewById<EditText>(R.id.search_src_text).setHintTextColor(color)
}

查询颜色:

fun SearchView.setTextColor(@ColorInt color: Int) {
    findViewById<EditText>(R.id.search_src_text).setTextColor(color)
}

在Appcompat v21中更改SearchView的样式

1)创建一个可配置的配置文件。此文件传统上命名为searchable.xml,必须保存在res / xml / project目录中。

<activity
        android:name=".activity.YourActivity"
        android:screenOrientation="portrait"
        android:theme="@style/Theme.App.Base">
        <meta-data android:name="android.app.searchable"
                   android:resource="@xml/searchable"/>
        <intent-filter>
            <action android:name="android.intent.action.SEARCH" />
            <category android:name="android.intent.category.DEFAULT"/>
        </intent-filter>
    </activity>

2)将元数据和属性添加到您的活动和操作以在AndroidManifest.xml中进行intent-filter

<style name="ActionBarThemeOverlay" parent="">
        <item name="android:textColorPrimary">@color/action_bar_text</item>
        <item name="colorControlNormal">@color/action_bar_text</item>
        <item name="colorControlHighlight">@color/body_text_2</item>
    </style>

<style name="Widget.App.SearchView" parent="Widget.AppCompat.Light.SearchView">
    <item name="closeIcon">@drawable/ic_action_cancel</item>
    <item name="voiceIcon">@drawable/ic_action_voice</item>
</style>

3)为指标,图标,提示和文字颜色创建样式。

 <style name="Theme.App.Base" parent="Theme">
    name="searchViewStyle">@style/Widget.App.SearchView</item>
</style>

4)将Widget.App.Search添加到AndroidManifest中添加的BaseAppTheme作为活动样式

<android.support.v7.widget.Toolbar
    android:id="@+id/toolbar_actionbar"
    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="@dimen/toolbar_height"
    android:background="@color/color_primary"
    app:theme="@style/ActionBarThemeOverlay"
    app:popupTheme="@style/ActionBarPopupThemeOverlay"
    app:subtitleTextAppearance="@style/Theme.ActionBar.SubtitleTextStyle"
    app:titleTextAppearance="@style/Theme.ActionBar.TitleTextStyle"/>

将ActionBarThemeOverlay添加到工具栏初始化

另一种解决方案:

 searchView_SA = (SearchView) findViewById(R.id.searcvViewSA);
 EditText searchEditText = (EditText)searchView_SA.findViewById(android.support.v7.appcompat.R.id.search_src_text);
    searchEditText.setTextColor(getResources().getColor(R.color.black));
    searchEditText.setHintTextColor(getResources().getColor(R.color.black));

看看这个: Link

这对我很有用:

Android.Widget.SearchView searchView = (Android.Widget.SearchView)FindViewById(Resource.Id.TxtSearchMaterial);
LinearLayout linearLayout1 = (LinearLayout)searchView.GetChildAt(0);
LinearLayout linearLayout2 = (LinearLayout)linearLayout1.GetChildAt(2);
LinearLayout linearLayout3 = (LinearLayout)linearLayout2.GetChildAt(1);
AutoCompleteTextView autoComplete = (AutoCompleteTextView)linearLayout3.GetChildAt(0);
autoComplete.SetTextColor(Color.White);
