当用户单击文本中的 URL 时会发生这种情况。我有一个包含 TextView 的布局的 listfragment。我正在 Android Studio 中使用 Android 设备模拟器进行测试。

当用户单击文本中的 URL 并在应用程序中使用 URL 时会发生这种情况。它是关于什么的？如果我需要 Urls 在文本中可点击，我该如何解决此错误？

我的安卓设备有浏览器。这是我进行 TextView html 设置的部分：

TextView tvhtml = (TextView) view;
final String html="<a href="http://www.google.com">Go to Google</a>";
tvhtml.setLinksClickable(true);
tvhtml.setMovementMethod (LinkMovementMethod.getInstance());
tvhtml.setText(Html.fromHtml(html));

这是我应用中的一些 sn-p 代码：

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
            super.onActivityCreated(savedInstanceState);
            getListView().setDivider(null);
            getListView().setSelector(R.drawable.selector_items);
            Bundle args = new Bundle();
            args.putString(DataProvider.COL_EMAIL, mListener.getProfileEmail());
            getLoaderManager().initLoader(0, args, this);
            this.postMesagesCAB();
    }
    .....

    ....

    adapter.setViewBinder(new SimpleCursorAdapter.ViewBinder() {
            @Override
            public boolean setViewValue(View view, Cursor cursor, int columnIndex) {
                switch (view.getId()) {
                    case R.id.text1:
                     TextView tvhtml = (TextView) view;
                     final String html="<a href="http://www.google.com">Go to Google</a>";
                     tvhtml.setLinksClickable(true);
                     tvhtml.setMovementMethod ( LinkMovementMethod.getInstance());
                     tvhtml.setText(Html.fromHtml(html));

    ...}

    private void postMesagesCAB() {
            final ListView listView = getListView();
            listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE_MODAL);

            listView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {

            @Override
            public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
                    ((ListView) parent).setItemChecked(position,
                            ((ListView) parent).isItemChecked(position));
                    //view.setBackgroundColor(Color.CYAN);
                return false;
                }
            });
            listView.setMultiChoiceModeListener(new AbsListView.MultiChoiceModeListener() {
                //private int nr = 0;

                @Override
                public void onItemCheckedStateChanged(ActionMode mode, int position,
                                                      long id, boolean checked) {
                    // Here you can do something when items are selected/de-selected,
                    // such as update the title in the CAB
                    Cursor c = ((SimpleCursorAdapter)listView.getAdapter()).getCursor();
                    c.moveToPosition(position);
                    String item = c.getString(0);

                    if (checked) {
                        nr++;
                    } else {
                        nr--;
                    }
                    int fsize=checkedItemPositions.size();
                    mode.setTitle(String.format("%d ite%s selecionado%s", fsize, fsize==1 ? "m" : "ns", fsize==1 ? "" : "s"));
                    mode.invalidate();

【问题讨论】：

标签： android exception android-intent android-fragments textview

【解决方案1】：

当用户点击文本中的 URL 时会发生这种情况

在这种情况下，URL 格式错误：

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

网址是href。这不是一个有效的 URL。

这里是我做 TextView html 设置的部分：

这不会编译，因为它不是有效的 Java。您不能有一个包含引号的带引号的字符串。您需要转义内部引号：

final String html="<a href=\"http://www.google.com\">Go to Google</a>";

如果我需要在文本中点击 URL，我该如何解决这个错误？

如果您是提供 HTML 的人，请确保它是有效的。

【讨论】：

谢谢您，Commons Ware 先生。我修复了网址并且效果很好。但是，点击无效网址时是否可能捕获异常？现在，当我点击无效的 url 时，我的应用程序崩溃了。
@LuizAlves：不使用您拥有的当前代码。调用startActivity() 并崩溃的是URLSpan，它是通过Html.fromHtml() 为您创建的。您需要找到 URLSpan 的出现并将它们替换为您自己的处理异常的克隆。
感谢您的帮助。您可能会向我指出一个替代链接，其中包含覆盖 URLSpan 的解决方案？我在堆栈溢出中发现此代码： private void fixTextView(TextView textView) { final SpannableString current = new SpannableString(textView.getText());最终 URLSpan[] 跨度 = current.getSpans(0, current.length(), URLSpan.class);整数开始，结束； for (URLSpan span : spans) { start = current.getSpanStart(span); end = current.getSpanEnd(span); current.removeSpan（跨度）； current.setSpan(new DefensiveURLSpan(span.getURL()), start, end, 0); } }
和私有静态类 DefensiveURLSpan 扩展 URLSpan { public DefensiveURLSpan(String url) { super(url); } @Override public void onClick(View widget) { try { android.util.Log.d(getClass().getSimpleName(), “到了！”); super.onClick（小部件）； } catch (ActivityNotFoundException e) { // 在这里做一些有用的事情 // android.text.SpannedString 不能转换为 android.text.SpannableString } } }
我将代码更改为：tvhtml.setMovementMethod(LinkMovementMethod.getInstance());跨越 htmlSpan = Html.fromHtml(html, p, null); fixTextView(tvhtml); tvhtml.setText(htmlSpan);但崩溃仍然发生。
