在Ice Cream Sandwich Android 4.0.3版本上使用Texview的getMaxLines()方法时,我遇到了崩溃日志,
I am getting below crash logs while using getMaxLines() method of Texview on Ice Cream Sandwich Android 4.0.3 version,
所以我真正的问题是,我的应用程序正在运行较低的sdk,而该sdk没有此getMaxLines()方法.
So I got the real issue is, that my application is running lower sdk which does not have this getMaxLines() method.
如何清除此崩溃.我没有找到其他替代方法
How can remove this crash. I didn't find any alternatives method

getMaxLines()(类似于TextViewCompat的解决方案.)
The getMaxLines() of TextViewCompat looks like the appropriate solution for this.
您还可以在 SourceCode ,然后复制所需的功能.
You can also take a look in the SourceCode of TextViewCompat, and copy the functions you need.
代码:
int maxLines = TextViewCompat.getMaxLines(yourtextView);代替:
int maxLines = yourtextView.getMaxLines();
我强烈建议使用支持库和TextViewCompat. 但是为了完整起见,这也是 TextViewCompatDonut 的getMaxLines:
I highly recommend using the support lib and TextViewCompat. But just for completeness, here is also the (current) source of TextViewCompatDonut 's getMaxLines :
static int getMaxLines(TextView textView) { if (!sMaxModeFieldFetched) { sMaxModeField = retrieveField("mMaxMode"); sMaxModeFieldFetched = true; } if (sMaxModeField != null && retrieveIntFromField(sMaxModeField, textView) == LINES) { // If the max mode is using lines, we can grab the maximum value if (!sMaximumFieldFetched) { sMaximumField = retrieveField("mMaximum"); sMaximumFieldFetched = true; } if (sMaximumField != null) { return retrieveIntFromField(sMaximumField, textView); } } return -1; }更多推荐
Android 4.0.3(API 15)及以下版本的TextView.getMaxLines()的替代方法
