Hello,
Im trying to do a basic startActivityForResult, but onActivityResult
is being called before the subactivity has a chance to call setResult.
----------------------------
main activity's menu handler for a specific button-press:
startActivityForResult(new Intent(this, SubActivity.class), someInt);
main activity's onActivityResult(int reqestCode, int resultCode,
Intent data) {
alert(Integer.toString(resultCode)); // always 0 (RESULT_CANCELED?)
alert(Integer.toString(requestCode)); // always someInt
if (data == null) { alert("returned null"); } // SEE BELOW
SubActivity extends listactivity:
onListItemClick(ListView l, View v, int i, long id) {
result = new Intent();
result.putExtra("key","value);
setResult(RESULT_OK, result);
finish();
}
-----------------------------
the activity and subactivity execute fine, the result is where my
problem comes in.
from "SEE BELOW" above:
this line will always alert "returned null", however if i change this
line to:
if (data.equals(null)) { alert("returned null"); }
i get a NullPointerException before the subactivity can visibly start.
the subactivity's onCreate normally logs to the debugger, but nothing
appears if I cause a NullPointerException, which leads me to believe
that onActivityResult is being called before the subactivity is
created.
i've taken a look at the notepad examples along other examples on the
web and my code appears consistent with them.
plz halp
