意圖功能無法正常工作

-4

即時通訊面臨的一個問題是，即時通過putExtra從電話活動發送線路號碼，並收到撥號活動的值。 getIntent函數第一次收到正確的值，但在第二次時，他無法收到正確的值。第1個谷值第2次出現。意圖功能無法正常工作

這是'Phone.java'類的所有代碼嗎？ –

檢查你是否在第二次傳遞相同的'sPhoneNo和nFreeLineNo' – SathishKumar

你是否在AndroidManifest的DialPad Activity中有任何標誌，如SINGLE_TOP或smth else。如果是這樣的創建可能不會被調用。在這種情況下，您必須重寫activity中的onNewIntent（）方法。 –

嘗試創建一個Bundle對象，然後通過intent.putExtras（束）傳遞，這是通過一個意圖通過額外的正確方法（我明白nFreeLineNo是一個int和sPhoneNo一個字符串）：

Intent intent = new Intent(Phone.this , DialPad.class); 
intent.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT); 
Bundle b = new Bundle(); 
b.putInt("LineNo", nFreeLineNo); 
b.putString("PhoneNo", sPhoneNo); 
intent.putExtras(b); 
startActivity(intent);

另外，在DialPa d getExtras這樣的：

Intent intent = getIntent(); 
Bundle b = intent.getExtras(); 
//Make sure you passed a bundle 
if (b != null){ 
    m_nLineNo = b.getInt("LineNo"); 
    m_sPhoneNo = b.getString("PhoneNo"); 
}else{ 
    //didnt pass bundle, Do what you want 
}

希望我幫你，我也有這個問題，解決了這個方式

如果不幫你，請從logcat的POST錯誤堆棧跟蹤

不是它不工作 – user3136235

請發佈stacktrace然後。否則，我忍不住 – BamsBamx

這是一個無用的答案。其他的東西已經是'Bundle'了。你可以簡單地使用'putExtra（）'（這個OP已經在做）來添加原語和'String'。把這些額外的東西放到一個額外的Bundle中，然後調用putExtras（）將這個Bundle中的數據複製到額外的Bundle中，只是簡單的開銷，並不能完成任何事情。最後，它和OP已經做的完全一樣（這就是爲什麼這個答案不能解決他的問題）。 –

Phone活動啓動DialPad活動使用Intent.FLAG_ACTIVITY_REORDER_TO_FRONT。這意味着如果任務堆棧中已有活動（未完成）DialPad實例，則該活動實例將簡單地移到前面（活動堆棧的頂部）。在這種情況下，onCreate()將不會在DialPad上被調用，因爲它不會重新創建活動。相反onNewIntent()將被調用。您尚未覆蓋DialPad中的此方法，因此您不會看到此方法調用。

既然你是在onCreate()提取的意圖演員LineNo和PhoneNo，你永遠只使用您從第一Intent獲取數據。這正是你所看到的問題。

爲了解決這個問題，覆蓋onNewIntent()並提取從在您在onNewIntent()收到Intent參數傳遞的額外LineNo和PhoneNo。
