我想要一个TextView是可折叠通过用户的接触。 当TextView的崩溃,我设置textview.setMaxLines(4); 如何清除我在我的扩展方法这种状态? 我只能想到电话setMaxLines()与价值一大批像10000。
I want a textview that is collapsable by user's touch. when the textview collapsed, I set textview.setMaxLines(4); how to I clear this state in my expand method? I can only think of call setMaxLines() with a value large number like 10000.
有没有实现这更好的方法呢?
Are there better ways to implement this?
感谢
其实,这样Android平台的确是由MAXLINE设置为Integer.MAX_VALUE。
Actually, the way android platform does that is by setting the MaxLine to Integer.MAX_VALUE.
textView.setMaxLines(Integer.MAX_VALUE);
此外,如果您使用的是Ellipsize,不要忘记设置为null。
also, if you are using Ellipsize, don't forget to set to null.
textView.setEllipsize(null);
只是检查如何Android框架做到这一点;)看setMaxLines(Integer.MAX_VALUE的);
just check how the android framework do just that ;) watch the setMaxLines(Integer.MAX_VALUE);
private void applySingleLine(boolean singleLine, boolean applyTransformation) {
mSingleLine = singleLine;
if (singleLine) {
setLines(1);
setHorizontallyScrolling(true);
if (applyTransformation) {
setTransformationMethod(SingleLineTransformationMethod.getInstance());
}
} else {
setMaxLines(Integer.MAX_VALUE);
setHorizontallyScrolling(false);
if (applyTransformation) {
setTransformationMethod(null);
}
}
}
