Im trying to listen or pass data from an BotomSheetDialogFragment into Fragment to change something on the Fragment (Just like a picker).
I've tried with getTargetFragment to instantiate the listener but getting a compiler error Found: 'MyFragment', required: 'android.support.v4.app.Fragment' less..
Any ideas or i'm takin the wrong approach?
public class MyBottomSheetDialogFragment extends BottomSheetDialogFragment implements View.OnClickListener {
ReportType reportType;
public interface OnChooseReasonListener {
void onChooseReason(ReportType reportType);
}
OnChooseReasonListener listener;
@Override
public void setupDialog(Dialog dialog, int style) {
super.setupDialog(dialog, style);
View contentView = View.inflate(getContext(), R.layout.picker_bottom_sheet_, null);
dialog.setContentView(contentView);
CoordinatorLayout.LayoutParams layoutParams =
(CoordinatorLayout.LayoutParams) ((View) contentView.getParent()).getLayoutParams();
CoordinatorLayout.Behavior behavior = layoutParams.getBehavior();
//get null here!!!:
listener = (OnChooseReasonListener) getParentFragment();// or with getTargetFragment();
}
@Override
public void onClick(View view) {
switch (view.getId()){
case R.id.cool_button:
this.reportType = ReportType.ME;
//trying to execute the lisstener on null
listener.onChooseReason(this.reportType);
dismiss();
break;
}
}}
And the fragment:
public class MyFragment extends Fragment
implements View.OnClickListener,
MyBottomSheetDialogFragment.OnChooseReasonListener {
//....code here
public void showPicker() {
//getting and compiler error Wrong 1st argument type.
// picker. setTargetFragment(MyFragment.this , 300);
picker.show(fm, picker.getTag());
}
@Override
public void onChooseReason(ReportType reportType) {
//not getting here
Log(TAG, "You choose something" + reportType.getValue());
}
}
Besides that it's not working, that code smells a little since you're coupling MyBottomSheetDialogFragment
with the object that created it.
The correct approach would be to have a method void setOnChooseReasonListener(OnChooseReasonListener listener)
on MyBottomSheetDialogFragment
and call it when you create the instance.
myBottomSheetDialogFragment.setOnChooseReasonListener(this);
