passing argument to DialogFragment
I used to send some values from my listview
How to send
mListview.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
@Override
public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
Favorite clickedObj = (Favorite) parent.getItemAtPosition(position);
Bundle args = new Bundle();
args.putString("tar_name", clickedObj.getNameTarife());
args.putString("fav_name", clickedObj.getName());
FragmentManager fragmentManager = getSupportFragmentManager();
TarifeDetayPopup userPopUp = new TarifeDetayPopup();
userPopUp.setArguments(args);
userPopUp.show(fragmentManager, "sam");
return false;
}
});
How to receive inside onCreate() method of DialogFragment
Bundle mArgs = getArguments();
String nameTrife = mArgs.getString("tar_name");
String nameFav = mArgs.getString("fav_name");
String name = "";
// Kotlin upload
val fm = supportFragmentManager
val dialogFragment = AddProgFargmentDialog() // my custom FargmentDialog
var args: Bundle? = null
args?.putString("title", model.title);
dialogFragment.setArguments(args)
dialogFragment.show(fm, "Sample Fragment")
// receive
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
if (getArguments() != null) {
val mArgs = arguments
var myDay= mArgs.getString("title")
}
}
as a general way of working with Fragments, as JafarKhQ noted, you should not pass the params in the constructor but with a Bundle
.
the built-in method for that in the Fragment
class is setArguments(Bundle)
and getArguments()
.
basically, what you do is set up a bundle with all your Parcelable
items and send them on.
in turn, your Fragment will get those items in it's onCreate
and do it's magic to them.
the way shown in the DialogFragment
link was one way of doing this in a multi appearing fragment with one specific type of data and works fine most of the time, but you can also do this manually.
So there is two ways to pass values from fragment/activity to dialog fragment:-
Create dialog fragment object with make setter method and pass value/argument.
Pass value/argument through bundle.
Method 1:
// Fragment or Activity
@Override
public void onClick(View v) {
DialogFragmentWithSetter dialog = new DialogFragmentWithSetter();
dialog.setValue(header, body);
dialog.show(getSupportFragmentManager(), "DialogFragmentWithSetter");
}
// your dialog fragment
public class MyDialogFragment extends DialogFragment {
String header;
String body;
public void setValue(String header, String body) {
this.header = header;
this.body = body;
}
// use above variable into your dialog fragment
}
Note:- This is not best way to do
Method 2:
// Fragment or Activity
@Override
public void onClick(View v) {
DialogFragmentWithSetter dialog = new DialogFragmentWithSetter();
Bundle bundle = new Bundle();
bundle.putString("header", "Header");
bundle.putString("body", "Body");
dialog.setArguments(bundle);
dialog.show(getSupportFragmentManager(), "DialogFragmentWithSetter");
}
// your dialog fragment
public class MyDialogFragment extends DialogFragment {
String header;
String body;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (getArguments() != null) {
header = getArguments().getString("header","");
body = getArguments().getString("body","");
}
}
// use above variable into your dialog fragment
}
Note:- This is the best way to do.
Using newInstance
public static MyDialogFragment newInstance(int num) {
MyDialogFragment f = new MyDialogFragment();
// Supply num input as an argument.
Bundle args = new Bundle();
args.putInt("num", num);
f.setArguments(args);
return f;
}
And get the Args like this
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mNum = getArguments().getInt("num");
...
}
