My Android app is displaying text in a TextView.
Are there any tags or anything to put around words that I want italicized? I don't need to set the TextView as italics because the whole sentence would be that way, and I only need specific words italicized.
You need to use a Spannable: see Is there any example about Spanned and Spannable text for an example.
This function sets a string as the text of a TextView and italicizes one or more spans within that string as long as the span or spans are marked with the tags [i] and [/i]. Of course, it can be modified for other types of styling.
private void doItalicize(TextView xTextView, String xString) {
ArrayList<Integer> IndexStart = new ArrayList<>();
ArrayList<Integer> IndexEnd = new ArrayList<>();
ArrayList<StyleSpan> SpanArray = new ArrayList<>();
int i = 0;
do {
IndexStart.add(i, xString.indexOf("[i]"));
IndexEnd.add(i, xString.indexOf("[/i]") - 3);
xString = xString.replaceFirst("\\[i\\]", "");
xString = xString.replaceFirst("\\[/i\\]", "");
xTextView.setText(xString, TextView.BufferType.SPANNABLE);
SpanArray.add(i, new StyleSpan(Typeface.ITALIC));
Log.d(LOG_TAG, "i: " + i);
i++;
} while (xString.contains("[i]"));
Spannable xSpannable = (Spannable) xTextView.getText();
for (int j = 0; j < i; j++)
xSpannable.setSpan(SpanArray.get(j), IndexStart.get(j), IndexEnd.get(j), Spanned
.SPAN_EXCLUSIVE_EXCLUSIVE);
}
I agree, this isn't a database issue. If this is not a custom app you're working on, you're out of luck. If it is, save the field in the database as HTML.
The solution would seem to be to save the content in the database as HTML and then output the HTML in the textview.
See the following article: How to display HTML in TextView?
