1.計(jì)算文字長度

計(jì)算文字總長度:TextView.getPaint().measureText(String text)

計(jì)算某一行文字實(shí)際長度:TextView.getLayout().getLineWidth(int line)
TextView.getLayout()可能為空
tvAreaName.post(new Runnable() {
@Override
public void run() {
Layout l = tvAreaName.getLayout();
if (l != null) {
if (l.getEllipsisCount(l.getLineCount()-1) > 0){
Log.d(TAG, "Text is ellipsized");
}else{
Log.d(TAG, "Text is not ellipsized");
}
}
}
});
