Question

I am feeding a ListView from a database in this way (nothing special), except
COL_TXT_TRANSL2 contains html formatting:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    Bundle extras = getIntent().getExtras();
    mCurrBookID = extras.getString("BookID");
    mCurrChapterNum = extras.getString("ChapterNum");
    mCurrChapterTitle = extras.getString("ChapterTitle");
    mGitaDB= Central.mDB;

    this.setTitle(mCurrChapterNum+"."+mCurrChapterTitle);
    setContentView(R.layout.chapterdisplay);

    //set chapter intro
    TextView tvIntro=(TextView) findViewById(R.id.textIntro);
    tvIntro.setText(Html.fromHtml(extras.getString("ChapterIntro")));


    try {
        String[] columns = new String[] { mGitaDB.COL_TXT_TEXT_NUM, mGitaDB.COL_TXT_TRANSL2 };
        int[] to = new int[] { R.id.number_entry, R.id.title_entry };

        mCursor=mGitaDB.GetGitaTexts(mCurrBookID, mCurrChapterNum);
        mAdapter = new SimpleCursorAdapter(this,
                R.layout.textslist_row, mCursor, columns, to);

        setListAdapter(mAdapter);
    }
    catch (Exception e) {
         String err="Error: " + e.getMessage();
         Toast toast = Toast.makeText(Central.context, err, 15000);

         toast.show();
    }

}

Now the problem is that the text displayed in this ListView has HTML formatting.

How can I make listview display this HTML formatting? Currently it is displayed as a plain text with all tags.

Assuming the HTML is fairly simple you can run it through this method: http://developer.android.com/reference/android/text/Html.html#fromHtml(java.lang.String) The resulting Spannable can be sent to a TextView in the ListView. Beware the fromHtml method is very slow and may slow down scrolling, you might want to cache the Spannables.
