How can I call OnActivityResult inside Fragment and how it work?

Question

I want to know is it possible on onActivityResult()to use inside Fragment and if yes then how it works please explain with example.

Organogenesis

if you are starting activity from fragment you can use OnActivityResult in activity – Border

Yes you can. In fragment override methdod onActivityResult and comment the super.onActivityResult and work what you want to do in this method. If you did not get how then let me know. – Exciting

@RameshKumar can you plz explain me with example. It's batter for me to understand as well implement. – Organogenesis

What are your requirements? are you gonna call startActivityForResult() from fragment or activity? – Calaverite

@ScottS Fragment – Organogenesis

if you are going to call startActivityForResult() from fragment then you shouldn't call "super.onActivityResult()", that will invoke the fragment's activity's onActivityResult(). – Calaverite

Answer 1

Within your fragment, you need to call:

startActivityForResult(myIntent, MY_INTENT_REQUEST_CODE);

where myIntent is the intent you already defined, and MY_INTENT_REQUEST_CODE is the int constant you defined in this fragment as a global variable as the request code for this intent.

And then, still inside your fragment, you need to override this method:

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
   //super.onActivityResult(requestCode, resultCode, data); comment this unless you want to pass your result to the activity.
}

I startActivityForResult in a fragment, and want to receive in either fragment/activity but onReceive data always null. – Amphetamine

Could you explain more? So what is "i"? and which command i need to call in activity and fragment? – Chantell

Answer 2

Yes you can use OnActivityResult inside Fragment.like this

public void onActivityResult(int requestCode, int resultCode, Intent intent) {
//super.onActivityResult(requestCode, resultCode, intent);
// perform your action here
}

Use this code in the activity.

public void onActivityResult(int requestCode, int resultCode, Intent intent) {
    super.onActivityResult(requestCode, resultCode, intent);
    Fragment fragment = (Fragment) getSupportFragmentManager().findFragmentByTag(childTag);
    if (fragment != null) {
        fragment.onActivityResult(requestCode, resultCode, intent);
    }
}

Definitely it will work, It will work same like in activities. You have call startActivityForResult(intent, requestCode); and normally get result in

@Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
}

Answer 5

if you call startActivityForResult() in fragment , result is delivered to parent activity.

public void onActivityResult(int requestCode, int resultCode, Intent intent) {
super.onActivityResult(requestCode, resultCode, intent);//will deliver result to desired fragment.
}

How is works

if you see requestCode in activity it will be like 655545, now

super.onActivityResult () will calculate desired fragment and request code.

if your fragment in ViewPager desired fragment index is found using

requestCode>>16

and requestCode is found by requestCode&0xffff.

In kotlin: - I can explain using two classes. if user go from one Activity to Another Activty and in back want data then this code help you

In class Abc
startActivityForResult(Intent(context, Bcd::class.java), 141)

  override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
        if (requestCode == 141) {
            if (data!!.extras.get("add").equals("safal")) {
                Log.e("Print Name",data!!.extras.get("add"))
            }
        }
    }

In Class Bcd
 val intent = Intent()
 intent.putExtra("add", "safal")
 setResult(Activity.RESULT_OK, intent)

you can call onActivityResult inside a Fragment in android studio 3.5 with ease

, first, there should be an activity where you are coming to get result . OnActivity result means it has to give a resultant view when prompted. Now in the previous activity lets say

first is an activity and the other is a fragment in the second activity

Xml code for first activity may be like the following:

     <RelativeLayout
     xmlns:androclass="http://schemas.android.com/apk/res/android"  
     xmlns:tools="http://schemas.android.com/tools"  
     android:layout_width="match_parent"  
     android:layout_height="match_parent"  
     tools:context=".MainActivity" >  
    <TextView  
    android:id="@+id/t1"  
    android:layout_width="wrap_content"  
    android:layout_height="wrap_content"  
    android:layout_alignLeft="@+id/button1"  
    android:layout_alignParentTop="true"  
    android:layout_marginTop="48dp"  
    android:text="Default Message" />  
 <Button  
    android:id="@+id/b1"  
    android:layout_width="wrap_content"  
    android:layout_height="wrap_content"  
    android:layout_below="@+id/textView1"  
    android:layout_centerHorizontal="true"  
    android:layout_marginTop="42dp"  
    android:text="GetMessage" />  
    </RelativeLayout>  

Xml code for second will be

     <RelativeLayout xmlns:androclass="http://schemas.android.com/apk/res/android"  
    xmlns:tools="http://schemas.android.com/tools"  
   android:layout_width="match_parent"  
   android:layout_height="match_parent"  
   android:paddingBottom="@dimen/activity_vertical_margin"  
   android:paddingLeft="@dimen/activity_horizontal_margin"  
   android:paddingRight="@dimen/activity_horizontal_margin"  
   android:paddingTop="@dimen/activity_vertical_margin"  
   tools:context=".SecondActivity" >  
<EditText  
    android:id="@+id/et1"  
    android:layout_width="wrap_content"  
    android:layout_height="wrap_content"  
    android:layout_alignParentTop="true"  
    android:layout_marginTop="61dp"  
    android:layout_toRightOf="@+id/textView1"  
    android:ems="10" />  
<TextView  
    android:id="@+id/t1"  
    android:layout_width="wrap_content"  
    android:layout_height="wrap_content"  
    android:layout_alignBaseline="@+id/editText1"  
    android:layout_alignBottom="@+id/editText1"  
    android:layout_alignParentLeft="true"  
    android:text="Enter Message:" />  
<Button  
    android:id="@+id/b1"  
    android:layout_width="wrap_content"  
    android:layout_height="wrap_content"  
    android:layout_below="@+id/editText1"  
    android:layout_centerHorizontal="true"  
    android:layout_marginTop="34dp"  
    android:text="Submit" />  
  </RelativeLayout>  

Now we will add startActivityForResult() method and onActivityResult() method

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {

    super.onActivityResult(requestCode, resultCode, data);

    if(requestCode==2)
    {
        String message=data.getStringExtra("MESSAGE");
        if (message!=null){
            profileNameText.setText(message);
        }
      }
     }


     @Override
    public void onClick(View v) {
    Intent i ;
    switch (v.getId()){
        case R.id.profile_option_menu:
            Log.i("profileclicked","profile_menu_image_clicked()");
            PopupMenu popupMenu = new PopupMenu(getActivity(),v);
            MenuInflater inflater = popupMenu.getMenuInflater();
            inflater.inflate(R.menu.profile_menu,popupMenu.getMenu());
            popupMenu.show();
            popupMenu.setOnMenuItemClickListener(new 
            PopupMenu.OnMenuItemClickListener() {
                @Override
                public boolean onMenuItemClick(MenuItem item) {
                    Intent i;
                    switch (item.getItemId()) {

                            case R.id.edit_det:
                            i = new Intent(getActivity().getApplicationContext(), 
                            FirstActivity.class);
                            startActivityForResult(i, 2);
                            return true;
                        default:
                            return onOptionsItemSelected(item);
                    }
                }
            });
            break;
    }
}

the code for the first activity class will be like this

        public class FirstActivity extends Activity {  
         EditText editText1;  
         Button button1;  
         @Override  
          protected void onCreate(Bundle savedInstanceState) {  
          super.onCreate(savedInstanceState);  
          setContentView(R.layout.activity_first);  
          editText1=(EditText)findViewById(R.id.et1);  
          button1=(Button)findViewById(R.id.b1);  
          button1.setOnClickListener(new OnClickListener() {  
            @Override  
            public void onClick(View arg0) {  
                String message=editText1.getText().toString();  
                Intent intent=new Intent();  
                intent.putExtra("MESSAGE",message);  
                setResult(2,intent);  
                finish();//finishing activity  
             }  
         });  
       }  

Here I am writing a method setResult(2, intent) where 2 is result code which will be checked inside fragment in first activity class it will check the result code and and if the condition satifies then it will change the text inside the TextView .

In Kotlin we can do this in a very simplistic way as followings:

In ExampleFragment.kt, let start activity to pic an image.

private val REQUEST_CODE_GALLERY = 101

private fun openGallery() {
    val intent = Intent(Intent.ACTION_PICK)
    intent.type = "image/*"

    requireActivity().startActivityFromFragment(this, intent, REQUEST_CODE_GALLERY)
}

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    super.onActivityResult(requestCode, resultCode, data)

    if(resultCode == Activity.RESULT_OK && requestCode == REQUEST_CODE_GALLERY) {
        Log.d("TAG", "${data.toString()}")
    }
}

Hope, this will be helpful!
