如何通过电子邮件发送 webview 内容正文？

Question

目前在我的应用程序中，我正在使用 webview 来显示我的 html 内容（正如预期的那样，它通过 assets 文件夹来，只是为了澄清）。但是，我已经集成了通过电子邮件发送功能，并且我看到主题正文和标题为空，而不是所选电子邮件中的焦点内容。 （比如说，当我选择通过电子邮件发送选项时，我选择了 gmail。我看到内容正文为空，而不是 web 视图中的内容）。任何人都这样做过或有想法，如何做同样的事情？ 这是我的代码： 我的 EmailUtils 类：

public class EmailUtils {
    public static String FEEDBACK_EMAIL = "Android.Feedback@mycompany.com";

    public static void shareNewsViaEmail(final Fragment fragment, final String emailSubject, final String emailBody){
        shareNewsViaEmailEx(fragment.getActivity(), emailSubject, emailBody);
    }

    public static void shareNewsViaEmailEx(final Context context, final String emailSubject, final String emailBody){
        final Intent emailIntent = new Intent(Intent.ACTION_SEND);
        emailIntent.setType("text/html");
        final String subjectAppendText = " " + context.getResources().getString(R.string.email_subject_append);
        emailIntent.putExtra(Intent.EXTRA_SUBJECT, emailSubject + subjectAppendText);
        emailIntent.putExtra(Intent.EXTRA_TEXT, emailBody);
        context.startActivity(Intent.createChooser(emailIntent, "Send Email"));
    }

}

部分我的片段类：

//The button where it's called:
@Override
    public void onMenuItemClicked(final int position) {
        mOptionsMenuHelper.hideMenu();
        menuButton.setSelected(false);
        switch (position) {

        case OptionMenuItems.EMAIL_STORY_POSITION:
            emailArticle();
            break;
        }
    }

private void emailArticle() {
        final Fragment fragment =  mArticleAdapter.getFragment(mArticlePager.getCurrentItem());

        if (fragment instanceof ArticleFragmentWebView)  {
            final String emailSubject = ((ArticleFragmentWebView)fragment).getHeadline();
            final String articleBody  = ((ArticleFragmentWebView)fragment).getArticleBody();
            final String newLine = getResources().getString(R.string.new_line);
            final String disclamer = getResources().getString(R.string.intellectual_property_info);
            final String emailBody = articleBody + newLine + disclamer;
            EmailUtils.shareNewsViaEmail(this, emailSubject, emailBody);
        }
    }

我该怎么做？

谢谢！ 这是文章fragmentwebview：

public class ArticleFragmentWebView extends AbsBaseArticleFragment {
    public static final String TAG_ARTICLE_FRAGMENT = "ArticleFragment";
    public static final String ARTICLE_POSITION = "article_position";
    public static final String CATEGORY_CODE = "article_code";
    private int mPositionInPager;
    private ArticleWebViewClient articleWebViewClient;

    @Override
    public void onActivityCreated(final Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        mPositionInPager = getArguments().getInt(ARTICLE_POSITION);
    }

    @Override
    public View onCreateView(final LayoutInflater inflater, final ViewGroup container, final Bundle savedInstanceState) {
        final View view = super.onCreateView(inflater, container, savedInstanceState);
        articleWebViewClient = new TechnicArticleWebViewClient(getActivity(), view);
        return view;
    }

    @Override
    public void onLoading() {
            final View fragmentView = getView();
            if (fragmentView != null) {
                LayoutUtils.showLoading(fragmentView, "");
            }
    }   
    @Override
    public void showLoading(View view) {
            LayoutUtils.showLoading(view, "");
    }
    @Override
    public void showResults(final Uri uri) {
            LayoutUtils.showResults(getView(), R.id.news_body);
    }   
    @Override
    public void setTextSize(TextSize textSize) {
        articleWebViewClient.increaseFontSize();
    }
    @Override
    public void showNoResults(final Uri uri) {
    //  LayoutUtils.showNoResult(getView(), R.id.details_container);
    }
    @Override
    public void showRelatedDivider() {

    }
    @Override
    protected void getRelatedQuotes() {

    }
    @Override
    public Uri onCreateContentUri() {
        final String articleCode = getArguments().getString(ARTICLE_CODE);
        return Uri.withAppendedPath(NewsContentProvider.ARTICLE_MYNEWS_URI, articleCode);
    }




    @Override
    public void onStart() {
        super.onStart();
    }

    public int getPositionInPager() {
        return mPositionInPager;
    }

    @Override
    protected int getFragmentLayoutId() {
        return R.layout.fragment_article_briefcase;
    }

    @Override
    protected int getArticleTextViewId() {
        return R.id.news_body;
    }

    @Override
    protected int getFlowTextViewId() {
        return R.id.tv;
    }

    @Override
    protected int getHeaderTextViewId() {
        return R.id.headline;
    }

    @Override
    protected int getMetadataTextViewId() {
        return R.id.timestamp_and_source;
    }

    @Override
    public void onMenuItemClicked(final int position) {
        //Do nothing
    }
    @Override
    public boolean setViewValue(final View view, final Cursor cursor, final int columnIndex) {
        if (view.getId() !=  R.id.news_body)            // paranoia
            return true;

        String article = cursor.getString(columnIndex);
        String storyId = cursor.getString(cursor.getColumnIndex(Briefcase.Columns.ID));
        return articleWebViewClient.setArticle(article, storyId);
    }
}

这是 getarticlebody 的模型类：

您尝试过 Html.fromHtml(string)。下面的代码非常适合在我的电子邮件中显示 html

final Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
String body = convertStreamToString(getResources().openRawResource(R.raw.share_email_body));
emailIntent.setType("text/html");
emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "my subject");
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, Html.fromHtml(body));
startActivity(Intent.createChooser(emailIntent, "Email:"));
