getIntent without extend活動

我想從ActMain傳遞一個字符串到SoundClsRslt，但是我的SoundClsRslt沒有擴展Activity。我嘗試了擴展活動，但它會導致其他問題，我問這裏：has no default constructor in android manifest。getIntent without extend活動

一切正常，直到程序到達「startActivity（i）;」，應用程序崩潰並且logcat顯示「無法找到顯式活動類{/com.Hugler.CB.SoundClsRslt};你是否在你的AndroidManifest.xml中聲明瞭這個活動？」。你知道什麼是錯的嗎？

接近ActMain的onCreate意圖的結束，以及對於getintent的SoundClsRslt的onSegment。

你能解釋一下你想傳遞給SoundClsRslt類的字符串嗎 – rahul

只是一個字符串？把它放在SharedPrefences中 – Nirel

爲了intent而在ActMain的onCreate的結尾附近，以及在onClass的SoundClsRslt for getintent。 –

您可以定義在類的構造函數的上下文。聊天后，你可以得到的意圖與myContext.getIntent()你的構造應該是這樣的：

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

一切正常，直到程序到達「startActivity（i）;」，應用程序崩潰並且logcat顯示「無法找到顯式活動類{/com.Hugler.CB.SoundClsRslt};你是否在你的AndroidManifest.xml中聲明瞭這個活動？」。你知道什麼是錯的嗎？ –

您已經通過您的ActMain實例您SoundClsRslt。因此，將m_pMain.getIntent（）而不是getIntent（）放在SoundClsRslt中並嘗試。

你無法啓動SoundClsRslt作爲一項活動。因爲這不是一項活動（根據你的代碼）。 – TdSoft

如果您想將easyPuzzle字符串傳遞給SoundClsRslt。首先在SoundClsRslt中創建一個setter方法，將其稱爲this（例如：m_pSoundClsRslt.yourMethodName（easyPuzzle）;） – TdSoft

getIntent without extend活動
