我的情况如下所述。
活动A可以调用B或D.
B在输入C之后调用C，然后按回，C将数据传回B.从B，如果我选择任一行，该行将把我带到D.
现在，我的问题是，从D开始，我想设置if-else语句来知道B中的哪个StartActivityForResult正在调用D，这样我就可以将相应的数据从C发送到B和D.
_____>B------>C
/ |
A----> |(B can call D and pass data from selected row from B to D.)
\_____>D

下面是用于从B中的行中单击启动D的代码片段，因为代码很长，所以我试着让它更清晰〜
tableRow1.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
Intent Intent1 = new Intent(AccountSetup.this, BluGuardProto2Activity.class);
Intent1.putExtra("activity", "activity1");
startActivityForResult(Intent1, 150);}});
答案 0 :(得分：1)
我不确定我是否完全理解这个问题，但无论如何我都会尝试一下。因此，您想知道活动B中用于启动活动D的两个不同选项中的哪一个？你是否可以在使用Intent.putExtra()？
启动时将其传递给活动D.类似的东西：
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
}
}
}
现在，这个例子远非完美（传递整数或类似可能更好的字符串），但它说明了我的意思。
看起来你正在尝试做一些类似于我的例子，但我注意到两件事：

您可以在活动中使用getCallingActivity来获取调用活动。 http://developer.android.com/reference/android/app/Activity.html#getCallingActivity()
