Java 无扩展活动的getIntent

我试图将字符串从ActMain传递到SoundClsRslt，但我的SoundClsRslt不扩展活动。我尝试扩展活动，但它将导致我在此处询问的其他问题：

---

在程序达到“startActivity（i）；”之前，一切都正常工作，应用程序崩溃，日志显示“找不到显式活动类{/com.Hugler.CB.SoundClsRslt}；您是否在AndroidManifest.xml中声明了此活动？”。你知道怎么了吗

---

在为intent创建ActMain和为getintent创建SoundClsRslt段的末尾

您可以在类的构造函数中定义上下文。聊天后，您可以使用

myContext.getIntent（）

获取意图。您的构造函数应该如下所示：

private Context myContext
public SoundClsRslt(ActMain pMain, Context context) {
    m_pMain = pMain;
    m_iID = 0;
    m_iID1 = 0;
    this.myContext = context;
    _fLog = null;
}

---

您已经将ActMain实例传递给SoundClsRslt。因此，请在SoundClsRslt中放入mpmain.getIntent（）而不是getIntent（），然后再试一次。

您能解释一下您试图传递给SoundClsRslt类的字符串是哪一个字符串吗？在创建ActMain for intent，以及在为getintent.ad创建SoundClsRslt段后，将其放入SharedReferences。你的manifast.xml和logcat也会在你的Menifest中声明com.Hugler.CB.SoundClsRslt活动。在程序达到“startActivity（i）；”之前，一切正常，应用程序崩溃，logcat说“找不到显式活动类{/com.Hugler.CB.SoundClsRslt}；您是否在AndroidManifest.xml中声明了此活动？”。您知道哪里出了问题吗？在程序达到“startActivity（i）”之前，一切都正常工作；，应用程序崩溃，logcat说“找不到显式活动类{/com.Hugler.CB.SoundClsRslt}；有
