将正/负按钮添加到 DialogFragment 的对话框 [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 一样有一个积极的和一个消极的按钮.如何在维护我编写的代码的同时实现这样的目标?

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

我就是这样想出来的.我删除了 onCreateView 并更改了 onCreateDialog.这个链接实际上有答案，所以所有的功劳都应该放在那里.我刚刚发布了它，以防万一有人先提出这个问题.

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();
}
