1.First create an interface

public static class ShowBottomSheetDialog extends BottomSheetDialogFragment {
//stp 1
public interface BottomSheetListener{//step 1
void onUpdateClick(Object updatedInfo,String CallBackTag);
}

//stp 2
2.create a member variable or that interface
private BottomSheetListener mBListener;//step 2

3.onattach init the member variable

try {
      mBListener=(BottomSheetListener) context;//step 3
}catch (ClassCastException e){
      throw new ClassCastException(context.toString()+" need to impliment BottomSheetListener interface.");
}

 

3.1: impliment the Listener 

public void setOnUpdateClickListener(BottomSheetListener mBListener){
    try {
        this.mBListener=(BottomSheetListener)mBListener;
       // mBListener=(BottomSheetListener) context;//step 3
    }catch (ClassCastException e){
        throw new ClassCastException(context.toString()+" need to impliment BottomSheetListener interface.");
    }
}

4.pass callback value————->>>>

 mBListener.onUpdateClick(newDeposit,Define.DEPOSIT_TAG);

}
}

========================NOw in activity -impliment the interface and get data

@Override
   public void onUpdateClick(Object updatedInfo, String CallBackTag) {
      if(CallBackTag.equals(DEPOSIT_TAG)){
         FireStoreModelDeposit updateDepo=(FireStoreModelDeposit) updatedInfo;
         //Helper.TOAST(this,updateDepo.getMem_deposit_amount());
         Helper.LOG("new_UPdated_deposit",updateDepo.getMem_deposit_amount());
   }
}
