Question

我试图在偏好设置屏幕中显示一些彩色文字。为此，我要创建一个这样的Spannable：

final String completeString = title + " - " + (TextUtils.isEmpty(currentValue) ? "?" : currentValue);
SpannableString span = new SpannableString(completeString);
span.setSpan(new ForegroundColorSpan(CURRENT_VALUE_COLOR), title.length() + 3, completeString.length(), 
Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
span.setSpan(new StyleSpan(Typeface.BOLD), title.length() + 3, completeString.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
myPref.setSummary(span);

当我的Preference位于PreferenceActivity主屏幕时，它可以正常工作，但当它在不同的PreferenceScreen中时，它的颜色不再显示

因此，例如，在这种情况下更改pref1摘要可以正常工作：

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

    <PreferenceCategory android:title="@string/cat1" >
        <EditTextPreference
            android:key="pref1"
            android:summary="@string/pref1_summary"
            android:title="@string/pref1_title" />
    </PreferenceCategory>
</PreferenceScreen>

但在以下情况下会失败：

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

        <PreferenceCategory android:title="@string/cat1" >
        <PreferenceScreen
            android:summary="@string/prefSubScreen1" >
            <ListPreference
                android:key="pref1"
                android:summary="@string/pref1_summary"
                android:title="@string/pref1_title"

... /＆GT;

知道如何让它发挥作用吗？

编辑：事实上，它看起来与Preference在不同的PreferenceScreen中无关。在ListPreference的情况下似乎失败了。为什么ListPreference无法将Spannable显示为摘要。

您可以在.container { line-height: 1.2em; margin: 2em; } .arrow { position: relative; display: inline-block; cursor: pointer; width: 35px; } .arrow::before { content: ''; display: block; position: absolute; top: 50%; border: 2px solid orange; width: 8px; height: 8px; transform: translateY(-50%) rotate(45deg); } .arrow::after { content: ''; display: block; position: absolute; height: 2px; width: 20px; top: -1px; right: 8px; background-color: orange; } .arrow--left::before { left: 8px; border-right: 0; border-top: 0; } .arrow--right::before { right: 10px; border-left: 1px; border-bottom: 1px; } .arrow:hover:before { border-color: black; } .arrow:hover:after { background: #000; }

中添加此主题

<div class="container">
  <div class="arrow arrow--left"></div>
  <div class="arrow arrow--right"></div>
</div>

并在您的//Code using System.Net; using Microsoft.SharePoint.Client; using (ClientContext context = new ClientContext("http://yourserver.sharepoint.com/")) { context.Credentials = new NetworkCredential("user", "password", "domain"); List announcementsList = context.Web.Lists.GetByTitle("List A"); // This creates a CamlQuery that has a RowLimit of 100, and also specifies Scope="RecursiveAll" // so that it grabs all list items, regardless of the folder they are in. CamlQuery query = CamlQuery.CreateAllItemsQuery(100); ListItemCollection items = announcementsList.GetItems(query); // Retrieve all items in the ListItemCollection from List.GetItems(Query). context.Load(items); context.ExecuteQuery(); foreach (ListItem listItem in items) { // We have all the list item data. For example, Title. label1.Text = label1.Text + ", " + listItem["Title"]; //label2.Text = label2.Text + ", " + listItem["Emp_x0020_ID"]; //EMP_x0020_ID could be internal name of SharePoint list column "EMP ID" //Likewise check the column internal name for all the columns //To find internal name, go to list settings and click each column //you will see towards the end of the url something like &Field=Emp_x0020_ID //"Emp_x0020_ID" is the internal name of the field } }

中定义此部分

style.xml

对我有用。
