问题描述
有 e.printStackTrace（）方法来打印特殊的错误，所以我想将整个异常字符串，并显示通过 Toast.makeText（）
我怎样才能做到这一点？
如果有更多的替代想法，那么请与我分享或暗示我。
There are e.printStackTrace() method to print exceptional error, so I would like to take entire exception in String and show it by Toast.makeText()
How can i do this?
If there are more alternate idea, then please share with me or suggest me.
推荐答案
使用下面这段code：
Use the following piece of code:
Writer writer = new StringWriter();
PrintWriter printWriter = new PrintWriter(writer);
exception.printStackTrace(printWriter);
String s = writer.toString();
＆NBSP;
更新（过时，见下文）
正如他的回答指出通过@BlackRider有一种方法来提取异常堆栈跟踪到的字符串（，但在Android 4.x的它并不总是可靠的，检查更新2以下的）：
As pointed by @BlackRider in his answer there is a way to extract an exception stacktrace into the String (but on Android 4.x it's not always reliable, check Update 2 below):
String stackTrace = Log.getStackTraceString(exception);
更新2
不过从Android 4.0的（API 14）开始， Log.getStackTraceString 方法是不可靠的了，因为的为的UnknownHostException （见的Android 问题＃21436 了解细节，简而言之就是：减少量日志喷出的应用程序在做网络正在恕我直言，一个可疑的决定，修改 Log.getStackTraceString 法）不可用的Android工程师的非错误状态。
因此，它仍然是最好使用code我提供在这篇文章的开头。
But starting from Android 4.0 (API 14) Log.getStackTraceString method is not reliable anymore, as it returns an empty string for UnknownHostException (see Android issue #21436 for the details, in short: "to reduce the amount of log spew that apps do in the non-error condition of the network being unavailable" Android engineers made imho a dubious decision to modify Log.getStackTraceString method).
Thus it's still better to use the code I provided at the beginning of this post.
