FirstActivity.Java
has a FragmentA.Java
which calls startActivityForResult()
.
SecondActivity.Java
call finish()
but onActivityResult
never get called which is
written in FragmentA.Java
.
FragmentA.Java
code:
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
// some code
Intent i = new Intent(getActivity(), SecondActivity.class);
i.putExtra("helloString", helloString);
getActivity().startActivityForResult(i, 1);
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
getActivity();
if(requestCode == 1 && resultCode == Activity.RESULT_OK) {
//some code
}
}
SecondActivity.Java
code:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//some code
Intent returnIntent = new Intent();
returnIntent.putExtra("result", result);
setResult(Activity.RESULT_OK,returnIntent);
finish();
}
I have tried debugging the code, but onAcitvityResult()
never get called.
This question is related to
android
android-fragmentactivity
The most important thing, that all are missing here is... The launchMode of FirstActivity must be singleTop. If it is singleInstance, the onActivityResult in FragmentA will be called just after calling the startActivityForResult method. So, It will not wait for calling of the finish() method in SecondActivity.
So go through the following steps, It will definitely work as it worked for me too after a long research.
In AndroidManifest.xml file, make launchMode of FirstActivity.Java as singleTop.
<activity
android:name=".FirstActivity"
android:label="@string/title_activity_main"
android:launchMode="singleTop"
android:theme="@style/AppTheme.NoActionBar" />
In FirstActivity.java, override onActivityResult method. As this will call the onActivityResult of FragmentA.
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
}
In FragmentA.Java, override onActivityResult method
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
Log.d("FragmentA.java","onActivityResult called");
}
Call startActivityForResult(intent, HOMEWORK_POST_ACTIVITY);
from FragmentA.Java
Call finish();
method in SecondActivity.java
Hope this will work.
Don't call finish()
in onCreate()
method then it works fine.
The fragment already has startActivityForResult
, which would call onActivityResult
in the fragment if you use it, instead of getActivity()
...
Kevin's answer works but It makes it hard to play with the data using that solution.
Best solution is don't start startActivityForResult()
on activity level.
in your case don't call getActivity().startActivityForResult(i, 1);
Instead, just use startActivityForResult()
and it will work perfectly fine! :)
just try this:
//don't call getActivity()
getActivity().startActivityForResult(intent, REQ_CODE);
//just call
startActivityForResult(intent, REQ_CODE);
//directly from fragment
_x000D_
We could call startActivityForResult()
directly from Fragment
So You should call this.startActivityForResult(i, 1);
instead of getActivity().startActivityForResult(i, 1);
Intent i = new Intent(getActivity(), SecondActivity.class);
i.putExtra("helloString", helloString);
this.startActivityForResult(i, 1);
Activity will send the Activity Result to your Fragment.
May it's late for the answer. But will be helpful for anyone.
In My case want to call activity from Fragment and setResult back from the fragment.
I have used getContext of Fragment Like.
startActivityForResult(new Intent(getContext(), NextActivity.class), 111);
And Set Result from Fragment
getActivity().setResult(Activity.RESULT_OK);
getActivity().finish();
Now Getting Result to Fragment with
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == Activity.RESULT_OK && requestCode == 111) {
}
}
You must write onActivityResult() in your FirstActivity.Java as follows
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
for (Fragment fragment : getSupportFragmentManager().getFragments()) {
fragment.onActivityResult(requestCode, resultCode, data);
}
}
This will trigger onActivityResult method of fragments on FirstActivity.java
onActivityResult() of MAinActivity will call , onActivityResult() of Fragement wont call because fragment is placed in Activity so obviously it come back to MainActivity
