Question

I’m looking for some sample code on how to use this correctly with a TextView.

the only thing I found in my Google searching was this test unit for the TextUtils class.

some guidance will be much appreciated.

EDIT:

I looked over the answer I got here and tried to implement it on my code. I used this code snippet:

    TextView title = (TextView) view.findViewById(R.id.listitemThreadsTitle);
    title.setVisibility(View.VISIBLE);

    TextPaint p = title.getPaint();
    String strTitle = "Moe, Joe, Isaac, Bethany, Cornelius, Charlie";
    title.setText(strTitle);
    float avail = p.measureText(strTitle);
    CharSequence ch = TextUtils.commaEllipsize(strTitle, p, avail, "one more", "%d more");
    title.setText(ch);

but the result was absolutely not what it’s supposed to be.

it was more like: Moe, Joe, Isaac, Betha…

instead of: Moe, Joe, Isaac + 3

Answer 1

public static CharSequence commaEllipsize (CharSequence text, TextPaint p, 
                                       float avail, String oneMore, String more)

Parameters:

text – the text to truncate
p – the Paint with which to measure the text
avail – the horizontal width available for the text
oneMore – the string for “1 more” in the current locale
more – the string for “%d more” in the current locale

Example Usage:

String text = "Apple, Orange, Mango, Banana";
TextView tv = new TextView(context);
float textWidth = tv.getPaint().measureText(text );
String tempStr = TextUtils.commaEllipsize(text, tv.getPaint(), textWidth, 
                                           "1 more", "%d more");
tv.setText(tempStr);

Update:

TextView title = (TextView) view.findViewById(R.id.listitemThreadsTitle);
title.setVisibility(View.VISIBLE);

TextPaint p = title.getPaint();
String strTitle = "Moe, Joe, Isaac, Bethany, Cornelius, Charlie";
title.setText(strTitle);
float avail = title.getMeasuredWidth();
CharSequence ch = TextUtils.commaEllipsize(strTitle, p, avail, "one more", "%d more");
title.setText(ch);
