Android: Programmatically calculate Listview Font Metrics

Question

I have a String and I need to truncate the string such that it fits on one line in a ListView.

Can anyone point me in the right direction?

Answer 1

You need to specify that in the XML of your list item row file.

These are the attributes you need to play with on your TextView;

android:singleLine="true"
android:maxLength="someLengthofCharacters(int)"
android:ellipsize="end"  //if you want an ellipse to be appended to the end of your String

EDIT: Try this approach to set the max character length of your TextView programmatically

TextView tv = new TextView(this);
int maxLength = 10;
InputFilter[] fArray = new InputFilter[1];
fArray[0] = new InputFilter.LengthFilter(maxLength);
tv.setFilters(fArray)

and set single line to true by using

TextView.setSingleLine or TextView.setLines(1)
