How do I get the text at a specific line in a TextView
I have a TextView
that is X lines long. H开发者_如何学运维ow do I get the text that is at, say, line 3?
Example: I have this TextView
This is line 1
And this is line 2
And this is line 3
I want to be able to get the String
at any one of these lines by itself, such as getting the String
at line 3 would return "And this is line 3". Searching for line breaks is not the solution I need, as it doesn't take into account text wrapping.
You can use textView.getLayout().getLineStart(int line)
and getLineEnd
to find the character offsets in the text.
Then you can just use textView.getText().substring(start, end)
-- or subsequence if you are using Spannables for formatting/etc.
Here is some code to supplement the accepted answer:
List<CharSequence> lines = new ArrayList<>();
int count = textView.getLineCount();
for (int line = 0; line < count; line++) {
int start = textView.getLayout().getLineStart(line);
int end = textView.getLayout().getLineEnd(line);
CharSequence substring = textView.getText().subSequence(start, end);
lines.add(substring);
}
