Question

I understand that there is this documentation

http://developer.android.com/reference/android/app/DialogFragment.html#AlertDialog

but as a new Android/Java le

Answer 1

Alert with custom view

public class MyAlertDialogFragment extends DialogFragment {

    public static final String TITLE = "dataKey";

    public static MyAlertDialogFragment newInstance(String dataToShow) {
        MyAlertDialogFragment frag = new MyAlertDialogFragment();
        Bundle args = new Bundle();
        args.putString(TITLE, dataToShow);
        frag.setArguments(args);
        return frag;
    }

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        String mDataRecieved = getArguments().getString(TITLE,"defaultTitle");

        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
        LayoutInflater inflater = getActivity().getLayoutInflater();
        View view = inflater.inflate(R.layout.alert_layout, null);

        TextView mTextView = (TextView) view.findViewById(R.id.textview);
        mTextView.setText(mDataRecieved);
        setCancelable(false);

        builder.setView(view);
        Dialog dialog = builder.create();

        dialog.getWindow().setBackgroundDrawable(
                new ColorDrawable(Color.TRANSPARENT));

        return dialog;

    }
}

And Alert with YesNoDialog interface

public class MyAlertDialogFragment extends DialogFragment {

    public static final String TITLE = "dataKey";
    private OnYesNoClick yesNoClick;

    public static MyAlertDialogFragment newInstance(String dataToShow ) {
        MyAlertDialogFragment frag = new MyAlertDialogFragment();
        Bundle args = new Bundle();
        args.putString(TITLE, dataToShow);
        frag.setArguments(args);
        return frag;
    }

    public void setOnYesNoClick(OnYesNoClick yesNoClick) {
        this.yesNoClick = yesNoClick;
    }

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        String mDataRecieved = getArguments().getString(TITLE,"defaultTitle");

        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());

        builder
                .setMessage("Message to Show")
                .setNegativeButton("No", new DialogInterface.OnClickListener() {

                    @Override
                    public void onClick(DialogInterface arg0, int arg1) {
                        if(yesNoClick != null)
                            yesNoClick.onNoClicked();
                    }
                })

                .setPositiveButton("Yes", new DialogInterface.OnClickListener() {

                    @Override
                    public void onClick(DialogInterface arg0, int arg1) {
                        if(yesNoClick != null)
                            yesNoClick.onYesClicked();
                    }
                });
        Dialog dialog = builder.create();

        dialog.getWindow().setBackgroundDrawable(
                new ColorDrawable(Color.TRANSPARENT));

        return dialog;

    }

    public interface OnYesNoClick{
        void onYesClicked();
        void onNoClicked();
    }
}

Use it like

private void showYesNoDialog(){
        MyAlertDialogFragment yesNoAlert = MyAlertDialogFragment.newInstance(
                "Data to Send");
        yesNoAlert.show(getFragmentManager(), "yesNoAlert");

        yesNoAlert.setOnYesNoClick(new MyAlertDialogFragment.OnYesNoClick() {
            @Override
            public void onYesClicked() {
                //yes or ok clicked
            }

            @Override
            public void onNoClicked() {
                //no or cancel clicked
            }
        });
    }
