在DialogFragment的对话框中添加正/负按钮 [英] Adding positive / negative Button to DialogFragment's Dialog

问题描述

我已经写了一个DialogFragment.现在，我意识到我希望它像AlertDialog一样有一个正按钮和一个负按钮.在维护我编写的代码的同时，如何实现这一目标?

I've already written a DialogFragment. Now I've realized that I want it to have a positive and a negative button just like an AlertDialog. How can I achieve such a thing while maintaining the code that I've written?

public class DoublePlayerChooser extends DialogFragment {
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);        

    setStyle(DialogFragment.STYLE_NORMAL,0);



}

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {

    return new AlertDialog.Builder(getActivity())
            .setTitle("title")
            .setPositiveButton("OK",
                new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int whichButton) {
                        // do something...
                    }
                }
            )
            .setNegativeButton("Cancel",
                new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int whichButton) {
                        dialog.dismiss();
                    }
                }
            )
            .create();
}



@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

    View v = inflater.inflate(R.layout.doubleplayerchooser, container, false);
    getDialog().setTitle("Enter Players");

    firstPlayerPicker =  (ImageButton) v.findViewById(R.id.imageButton1);
    firstPlayerPicker.setOnClickListener(new OnClickListener() {
        public void onClick(final View v){

            callContactPicker(1);

        }       
    });

    secondPlayerPicker =  (ImageButton) v.findViewById(R.id.ImageButton01);
    secondPlayerPicker.setOnClickListener(new OnClickListener() {
        public void onClick(final View v){

            callContactPicker(2);

        }       
    });

    loadFromFile =  (ImageButton) v.findViewById(R.id.imageButton2);
    loadFromFile.setOnClickListener(new OnClickListener() {
        public void onClick(final View v){



        }       
    });

    firstTextfield =  (EditText) v.findViewById(R.id.editText1);
    secondTextfield =  (EditText) v.findViewById(R.id.EditText01);

    firstImage = (ImageView) v.findViewById(R.id.imageView1);
    secondImage = (ImageView) v.findViewById(R.id.ImageView01);



    return v;
}

推荐答案

这就是我的想法.我擦除了onCreateView并更改了onCreateDialog. 这个链接实际上有答案，所以所有功劳都应该放在那儿.我刚刚发布了它，以防万一有人首先碰到这个问题.

This is how I figured it out. I erased the onCreateView and altered the onCreateDialog. This link actually had the answer so all the credit should go there. I've just posted it just in case anyone bumps in this question first.

    @Override
public Dialog onCreateDialog(Bundle savedInstanceState) {

    AlertDialog.Builder b=  new  AlertDialog.Builder(getActivity())
    .setTitle("Enter Players")
    .setPositiveButton("OK",
        new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int whichButton) {
                // do something...
            }
        }
    )
    .setNegativeButton("Cancel",
        new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int whichButton) {
                dialog.dismiss();
            }
        }
    );

    LayoutInflater i = getActivity().getLayoutInflater();

    View v = i.inflate(R.layout.doubleplayerchooser,null);

    firstPlayerPicker =  (ImageButton) v.findViewById(R.id.imageButton1);
    firstPlayerPicker.setOnClickListener(new OnClickListener() {
        public void onClick(final View v){

            callContactPicker(1);

        }       
    });

    secondPlayerPicker =  (ImageButton) v.findViewById(R.id.ImageButton01);
    secondPlayerPicker.setOnClickListener(new OnClickListener() {
        public void onClick(final View v){

            callContactPicker(2);

        }       
    });

    loadFromFile =  (ImageButton) v.findViewById(R.id.imageButton2);
    loadFromFile.setOnClickListener(new OnClickListener() {
        public void onClick(final View v){



        }       
    });

    firstTextfield =  (EditText) v.findViewById(R.id.editText1);
    secondTextfield =  (EditText) v.findViewById(R.id.EditText01);

    firstImage = (ImageView) v.findViewById(R.id.imageView1);
    secondImage = (ImageView) v.findViewById(R.id.ImageView01);


    b.setView(v);
    return b.create();
}
