Communication Between Fragment And Dialogfragment

I'm trying to make a Fragment to show a Dialog using DialogFragment API. My dialog only has an EditText view and I want to pass the string wrote on it back to the Fragment. I'm abl

Solution 1:

You can use the setTargetFragment and getTargetFragment methods of Fragment. You can set your Fragment as the target of the DialogFragment and then retrieve a reference to it from within the DialogFragment.

Solution 2:

you can use callbacks. just implement a "done" button or something like that in your dialogfragment.

so in your dialogfragment do something like this:

protectedOnDialogClickedListenercallback=null;

publicinterfaceOnDialogClickedListener {
    publicabstractvoidonDialogClicked(int position);
}

publicvoidsetOnDialogClickedListener(OnDialogClickedListener l){
    callback = l;
}

button.setOnItemClickListener(newOnItemClickListener() {
    publicvoidonItemClick(AdapterView<?> parent, View v, int position, long id) {
        callback.onDialogClicked(position);
        dismiss();
    }
});

in your activity do something like this:

finalYourFragmentf= YourFragment .newInstance(0);
f.show(ft, "YourFragment ");
f.setOnDialogClickedListener(newOnDialogClickedListener() {
    @OverridepublicvoidonDialogClicked(int position) {
        updateText(position);
        f.dismiss();
    }
});
