使用 Linkify Android 打开 Activity

我想在用户使用 linkify 单击 textView 时打开 Activity... 这是我的代码：

Pattern tagMatcher = Pattern.Compile("#([A-Za-z0-9_-]+)");

            //Scheme for Linkify, when a word matched tagMatcher pattern,
            //that word is appended to this URL and used as content URI
            String newActivityURL = "content://Solution.Project.WelcomeActivity";
            //Attach Linkify to TextView
            wrapper.Text.Text = post.PostText;
            Linkify.AddLinks(wrapper.Text, tagMatcher, newActivityURL);

和我的安卓manifest.xml

 <application android:icon="@drawable/Icon" android:label="Welcome">
    <activity android:name=".WelcomeActivity" android:label="@string/WelcomeText">
        <intent-filter>
    <action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.DEFAULT" />
    <category android:name="android.intent.category.BROWSABLE" />
        </intent-filter>
    </activity>
 </application>

当用户点击textView，它抛出以下异常：

android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.VIEW dat=content://Solution.Project.welcomeactivity (has extras) }

您的意图过滤器应如下所示：

   <intent-filter android:label="@string/filter_title_viewgizmos">
    <action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.DEFAULT" />
    <category android:name="android.intent.category.BROWSABLE" />
    <!-- Accepts URIs that begin with "http://www.example.com/gizmos” -->
    <data android:scheme="content"
          android:host="Solution.Project.WelcomeActivity" />

</intent-filter>

你失踪了data标签如下图

scheme可以是 http 或您自己定制的。

host是链接，例如 xyz.com

路径前缀是可选的，例如 /homepage

 <data android:scheme="content"
          android:host="Solution.Project.WelcomeActivity" />
