Document

Returns the maximum height of TextView in terms of number of lines or -1 if the maximum height was set using #setMaxHeight(int) or #setHeight(int) .

Usage

From source file:Main.java

private static int getMaxLines(TextView view) {
    int maxLines = -1; // No limit (Integer.MAX_VALUE also means no limit)

    TransformationMethod method = view.getTransformationMethod();
    if (method != null && method instanceof SingleLineTransformationMethod) {
        maxLines = 1;/*from   w  w w  .  j  a  va2  s. co  m*/
    } else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
        // setMaxLines() and getMaxLines() are only available on android-16+
        maxLines = view.getMaxLines();
    }

    return maxLines;
}
