Question

我尝试过简单的事情。在AlertDialog消息中包含超链接。我可以包含超链接，并根据需要绘制为超链接。但是当点击它时，应用程序崩溃了：

ActivityMain.java

AlertDialog ad = new AlertDialog.Builder(this).create();
        ad.setMessage(Html.fromHtml("<a href=\\\"http://www.google.com\\\">Check this link out</a>));
        ad.setButton("OK", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                dialog.dismiss();
            }
        });
        ad.show();
        TextView textView = (TextView) ad.findViewById(android.R.id.message);
        textView.setTextSize(TypedValue.COMPLEX_UNIT_DIP, 15);
        textView.setMovementMethod(LinkMovementMethod.getInstance());

在我的 AndroidManifext.xml 中，我添加了intend-filter android.intent.action.VIEW ，但它仍然崩溃。

        <activity
            android:name="org.app.test"
            android:screenOrientation="portrait"
            android:label="@string/app_name"
            android:theme="@style/AppTheme"
            >

            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <action android:name="android.intent.action.VIEW" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

Logcat错误消息

出了什么问题？

Answer 1

如果我使用Linkify，可以无误地点击链接，并在网络浏览器中打开。

String msg = "<a href=\"http://www.google.com\">Check this link out</a>";

final SpannableString s = new SpannableString(msg);
Linkify.addLinks(s, Linkify.ALL);

AlertDialog ad = new AlertDialog.Builder(this)
                        .setMessage(s)
                        .setTitle("Click a link in AlertDialog")
                        .setIcon(android.R.drawable.ic_dialog_info)
                        .create();

TextView textView = (TextView) ad.findViewById(android.R.id.message);
textView.setMovementMethod(LinkMovementMethod.getInstance());

那是 ALMOST 我想要实现的......但是链接没有正确呈现...... :(

这是打印到我的AlertDialog中的结果：

＆LT; a href = \“http://www.google.com \”＆gt;检查此链接＆lt; / A＆GT;

当然它应该显示没有HTML标签，像这样 - ＆gt; Check this link out ......

所以这是最终的解决方案，以便在AlertDialogs中获得良好格式化的超链接，而不会出现任何错误：

    String msg = "Check this link out, and I will send you to Google.";

    AlertDialog ad = new AlertDialog.Builder(this)
            .setTitle("Open a Hyperlink inside AlertDialog")
            .setMessage(msg)
            .setIcon(android.R.drawable.ic_dialog_info)
            .create();

    ad.show();

    TextView message = (TextView) ad.findViewById(android.R.id.message);
    textView.setMovementMethod(LinkMovementMethod.getInstance());
    addLinks(message , "Check this link out", "http://www.google.com");

我们唯一需要做的就是在我们的类中添加一个小的新函数 addLinks（Textview，String，String）。否则，当我们只使用Linkify.addLinks（TextView textView，Pattern pattern，String scheme）时，生成的URL将是错误的。

public static void addLinks(TextView textView, String linkThis, String toThis)
    {
        Pattern pattern = Pattern.compile(linkThis);
        String scheme = toThis;
        Linkify.addLinks(textView, pattern, scheme, new Linkify.MatchFilter() {
            @Override
            public boolean acceptMatch(CharSequence s, int start, int end) {
                return true;
            }
        }, new Linkify.TransformFilter() {

            @Override
            public String transformUrl(Matcher match, String url) {
                return "";
            }
        });
    }

所以，这让它真的很舒服！：）
