我正在使用startActivity调用另一个Activity，并且收到“Activity Not Found Exception”(找不到 Activity )。这是我的代码:
TextView textView = (TextView) itemClicked;
String strText = textView.getText().toString();
String key = "symptom";
Intent mIntent = new Intent(symptomActivity.this, symptomRemedyActivity.class);
Bundle mBundle = new Bundle();
mBundle.putString(key, strText);
mIntent.putExtras(mBundle);
startActivity(mIntent);
这是Logcat的输出:
INFO/ActivityManager(59): Displayed activity com.android.homeopathy/.HomeopathyActivity: 5542 ms (total 39089 ms)
INFO/ARMAssembler(59): generated scanline__00000077:03545404_00000004_00000000 [ 47 ipp] (67 ins) at [0x3283e0:0x3284ec] in 627000 ns

INFO/ActivityManager(59): Starting activity: Intent { cmp=com.android.homeopathy/.symptomRemedyActivity (has extras) }
这是调试窗口输出:

symptomRemedyActivity是我项目中的另一项 Activity 。是否需要执行一些操作，例如导入symptomRemedyActivity，以便startActivity可以看到symptomRemedyActivity，以删除此“未找到 Activity 异常”？
最佳答案
我知道这是一篇旧文章，但目前在google搜索之上，因此对于以后再来的任何人:ActivityNotFound可能是由于您要创建的 Activity 中onCreate中未处理的异常所致。我花了一段时间才注意到我在那儿造成了nullPointerException，因为我没有在找它。
