问题描述
我有以下的catch语句在我的Android应用程序,我想通过显示敬酒任何错误信息,我能做到这一点?
I have the following catch statement in my Android application and I would like to display any error messages via toast, can I do that?
catch (Exception e)
{
//Helper.displayExceptionMessage(this, e.getMessage());
Toast.makeText(this, error, Toast.LENGTH_SHORT).show();
e.printStackTrace();
}
public static void displayExceptionMessage(Context context, String msg)
{
Toast.makeText(context, msg , Toast.LENGTH_LONG).show();
}
我也试图让一个辅助类,以显示消息,但我不知道如何解决帮手。
I’ve also tried to make a helper class to display the message but I have no idea how to resolve "Helper".
推荐答案
谢谢你们,
e.getMessage()的伎俩,
e.getMessage() did the trick,
我做了这个样子,
{
...
catch (Exception e)
{
e.printStackTrace();
displayExceptionMessage(e.getMessage());
}
}
public void displayExceptionMessage(String msg)
{
Toast.makeText(this, msg, Toast.LENGTH_SHORT).show();
}
这样我可以用它来测试在整个活动我猜。我不知道它可能是矫枉过正!
That way I can use it for testing throughout the whole activity I Guess. I don't know it could be overkill!!!
干杯,
