不幸的是，Project_Name已停止
我有一个简单的应用程序，您在textview中输入文本，然后按提交，它会在另一个活动中显示文本。 但是，当我按提交时，给我一条消息“不幸发送已经停止”我看了SO上的其他线程，但不幸的是myfirstproject停止工作错误在java似乎最接近他们说检查LogCat文件，它想出了不止一个错误：

有人能帮我吗？
如果您更好地查看错误日志，您会看到：
引起：android.content.ActivityNotFoundException：无法找到显式活动类{com.point / com.point.DisplayMessageActivity}; 你在AndroidManifest.xml中声明了这个活动吗？
那么，你的DisplayMessageActivity在AndroidManifest.xml文件中声明了？
将其添加到Application Tag下的清单文件中：
从您的堆栈跟踪：
Unable to find explicit activity class {com.point/com.point.DisplayMessageActivity}; have you declared this activity in your AndroidManifest.xml?
你呢？
