textview多行设置ellipsize="end"并不显示省略号。这是android4.0以下系统的bug，google发现有个家伙写了个开源控件

http://android-textview-multiline-ellipse.googlecode.com/ 号称解决该问题。但实际测试还是存在问题，只好自己另寻找解决方案。下面的代码替换掉该控件的resetText函数，几乎可实现多行显示省略号 。

private void resetText() {

String workingText = fullText;

boolean ellipsized = false;

int maxLines = this.maxLines > 0 ? this.maxLines : 1;

if (maxLines <= getLineCount()) {

Paint paint = getPaint();

float mw = (getMeasuredWidth() - getPaddingLeft() - getPaddingRight())

* maxLines;

if (paint.measureText(workingText) > mw) {

int ei = (int) ((mw - paint.measureText("...")) / paint

.getTextSize()) - 1;

if (ei < workingText.length()) {

workingText = workingText.substring(0, ei - 1) + "...";

}

}

ellipsized = true;

}

if (!workingText.equals(getText())) {

programmaticChange = true;

try {

setText(workingText);

} finally {

programmaticChange = false;

}

}

isStale = false;

if (ellipsized != isEllipsized) {

isEllipsized = ellipsized;

for (EllipsizeListener listener : ellipsizeListeners) {

listener.ellipsizeStateChanged(ellipsized);

}

}

}

实际这个解决方法还是有点小问题。什么问题请留意下文分解^_^。
