識別哪個StartActivityForResult正在調用當前活動

我有如下所述的情況。識別哪個StartActivityForResult正在調用當前活動

活動A可以撥打B或D.

B調用C，輸入細節成C，並按回後，C將數據傳遞迴B.從B，如果我選擇行，行會帶我到D.

現在，我的問題是，從D，我想設置if-else語句來知道B的哪個StartActivityForResult正在調用D，以便我可以將相應的數據從C發送到B併發送到D 。

 _____>B------>C 
    / | 
A---->  |(B can call D and pass data from selected row from B to D.) 
     \_____>D

下面的代碼使用，開始從d片斷B中因爲代碼是長排的點擊，所以我儘量說得清楚〜

tableRow1.setOnClickListener(new OnClickListener() { 
     public void onClick(View v) { 
       Intent Intent1 = new Intent(AccountSetup.this, BluGuardProto2Activity.class); 
       Intent1.putExtra("activity", "activity1"); 
       startActivityForResult(Intent1, 150);}});

該代碼看起來很好看一眼。將一個斷點放在String選項= getIntent（）。getStringExtra（「activity」）;字符串是否爲空？ – britzl 2013-05-14 10:38:28

對不起，我不知道如何識別這個〜我的資料不能共享:-( 我已經堅持了2天~~ !!!!!!：〜（ – Angela 2013-05-15 08:16:34

對不起，但是我不能幫助你更多。你能讓我們知道String choice = getIntent（）。getStringExtra（「activity」）的值嗎？？它是null？ – britzl 2013-05-15 10:05:01

我不確定我是否完全理解了這個問題，不過我要試一試。所以你想知道Activity B中用於啓動Activity D的兩個不同選項中的哪一個？難道你不能簡單地將它傳遞給活動D時，它使用Intent.putExtra()啓動？

是這樣的：現在

public class ActivityB extends Activity { 

    private void startActivityDFromFirstChoice() { 
     Intent i = new Intent(this, ActivityD.class); 
     i.putExtra("CHOICE", "first"); 
     startActivityForResult(i, 1234); 
    } 

    private void startActivityDFromSecondChoice() { 
     Intent i = new Intent(this, ActivityD.class); 
     i.putExtra("CHOICE", "second"); 
     startActivityForResult(i, 1234); 
    } 

} 


public class ActivityD extends Activity { 

    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 

     String choice = getIntent().getStringExtra("CHOICE"); 
     if(choice != null && choice.equals("first")) { 
      // activity was launched from first choice in B 
     } 
     else if(choice != null && choice.equals("second")) { 
      // activity was launched from second choice in B 
     } 
    } 
}

，這個例子遠非完美（字符串傳遞，其中的int或類似的可能會更好），但它說明了我的意思。

好像你正在試圖做同樣的事情對我的例子，但我注意到兩兩件事：

我似乎無法找到活動d一個地方，你實際上得到了額外的字符串，你你必須在Activity D的某個地方添加getIntent（）。getStringExtra（「activity」）。
在Intent1.putExtra（「activity1」，「activity1」）;而在另一個Intent2.putExtra（「activity」，「activity2」）;在這兩種情況下，它不應該是「活動」嗎？

正是，@britzl！你的輝煌〜這就是我的問題〜現在我的代碼和你的代碼是一樣的，但不幸的是數據仍然沒有出現在我的活動中D一旦我使用if-else語句。但如果沒有if-else語句，那麼我的數據會顯示在活動D〜 – Angela 2013-05-14 07:07:21

可以幫我識別我的問題??????我被卡在這裏〜:-( – Angela 2013-05-14 07:44:37

請發表你正在使用的代碼，這樣會更容易幫到你 – britzl 2013-05-14 07:45:34

您可以在您的活動中使用getCallingActivity來獲取調用活動。 http://developer.android.com/reference/android/app/Activity.html#getCallingActivity()
