android - 工具栏 SearchView 光标颜色

Question

你好。我正在尝试更改 SearchView 文本输入光标颜色，但遇到了很多困难。我发现它取决于我在 AppTheme 中定义的 colorAccent 值，但我无法更改它，因为它会影响很多其他 UI 元素。当我尝试使用自己的 colorAccent 参数为我的工具栏设置自定义样式时，没有任何变化，光标仍然是相同的颜色(非常接近工具栏，所以它似乎是不可见的)。

我的工具栏

    <android.support.design.widget.AppBarLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/AppTheme.AppBarOverlay">

    <android.support.v7.widget.Toolbar
        android:id="@+id/newsfeed_toolbar"
        android:layout_width="match_parent"
        android:visibility="visible"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        style="@style/SearchStyle"
        app:titleTextAppearance="@style/toolbar_title_style"
        popupTheme="@style/AppTheme.PopupOverlay" >

    </android.support.v7.widget.Toolbar>

    </android.support.design.widget.AppBarLayout>

我的搜索菜单

   <?xml version="1.0" encoding="utf-8"?>
   <menu xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:app="http://schemas.android.com/apk/res-auto">

   <item
    android:id="@+id/newsfeed_search"
    android:icon="@mipmap/ic_search"
    app:showAsAction="always|collapseActionView"
    app:actionViewClass="android.support.v7.widget.SearchView"
    android:title="Search"/>
    </menu>

我的风格

<style name="SearchStyle" parent="@style/ThemeOverlay.AppCompat.ActionBar">
<item name="android:textCursorDrawable">@android:color/white</item>
<item name="android:colorAccent">@android:color/white</item>
</style>

Activity 代码

toolbar = (Toolbar) findViewById(R.id.newsfeed_toolbar);
setSupportActionBar(toolbar);
 @Override
public boolean onCreateOptionsMenu( Menu menu) {
    getMenuInflater().inflate( R.menu.menu, menu);

    MenuItem searchItem = menu.findItem( R.id.newsfeed_search);
    SearchView searchView = (SearchView) searchItem.getActionView();
    \\The next few lines is what I tried from other StackOverFlow responses, but no success    
final int textViewID = searchView.getContext().getResources().getIdentifier("android:id/search_src_text",null, null);
    final AutoCompleteTextView searchTextView = (AutoCompleteTextView) searchView.findViewById(textViewID);
    try {
        Field mCursorDrawableRes = TextView.class.getDeclaredField("mCursorDrawableRes");
        mCursorDrawableRes.setAccessible(true);
        mCursorDrawableRes.set(searchTextView, android.R.color.white); //This sets the cursor resource ID to 0 or @null which will make it visible on white background
    } catch (Exception e) {}
    searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
        @Override
        public boolean onQueryTextSubmit(String query) {
            searchWord = query;
            \\API Stuff

            return false;
        }
        @Override
        public boolean onQueryTextChange(String s) {
            if (s.length()>5) {
                \\API Stuff
            return false;
        }
    });
    MenuItemCompat.setOnActionExpandListener(searchItem,new MenuItemCompat.OnActionExpandListener() {

        @Override
        public boolean onMenuItemActionExpand(MenuItem item) {
            searchMode = true;
            return true;
        }

        @Override
        public boolean onMenuItemActionCollapse(MenuItem item) {
            searchMode = false;
            searchWord = null;
            pageCount = 1;
            return true;
        }
    });
    return true;
}

我有同样的问题，但我终于通过使用 style

找到了

将此项目样式添加到您的Activity Theme styles.xml

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
        <item name="autoCompleteTextViewStyle">@style/cursorColor</item>
    </style>

<style name="cursorColor" parent="Widget.AppCompat.AutoCompleteTextView">
    <item name="android:textCursorDrawable">@drawable/cursor</item>
</style>

然后在drawable文件夹中添加cursor.xml

    <?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" >
    <solid android:color="#FFFFFF" />
    <size android:width="1dp" />
</shape>

并删除您在工具栏中设置的任何搜索样式。
