public class TestDialog extends DialogFragment implements View.OnClickListener{
    TextView textView;
    EditText editText;
    Button button_save;
    Button button_dismiss;
    Button button_help;
              
    public static TestDialog newInstant(String prompt)
    {
        TestDialog td = new TestDialog();
        Bundle bundle = new Bundle();
        bundle.putString("prompt", prompt);
        td.setArguments(bundle);
        return td;
    }
    public void onClick(View arg0) {
        OnDialogDoneListener act = (OnDialogDoneListener) getActivity();
        if(arg0.getId() == R.id.btn_dismiss)
        {
            act.onDialogDone(getTag(), true, null);
            dismiss();
            return;
        }
        if(arg0.getId() == R.id.btn_help)
        {
                      
        }
        if(arg0.getId() == R.id.btn_save)
        {
//          TextView v = (TextView)getView().findViewById(R.id.textView);
            act.onDialogDone(getTag(), false, editText.getText());
            dismiss();
            return;
        }
    }
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.dialog, container, false);
                  
        textView = (TextView)v.findViewById(R.id.promptmessage);
        editText = (EditText)v.findViewById(R.id.inputtext);
                  
        button_save = (Button)v.findViewById(R.id.btn_save);
        button_dismiss = (Button)v.findViewById(R.id.btn_dismiss);
        button_help = (Button)v.findViewById(R.id.btn_help);
                  
        button_save.setOnClickListener(this);
        button_dismiss.setOnClickListener(this);
        button_help.setOnClickListener(this);
                  
        return v;
    }

activity实现自定义的一个借口,与Dialog类交互

public interface OnDialogDoneListener {
    public void onDialogDone(String tag, boolean cancel, CharSequence message);
}

activity类:

public class MainActivity extends Activity implements OnDialogDoneListener {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
//      getMenuInflater().inflate(R.menu.main, menu);
        super.onCreateOptionsMenu(menu);
        menu.add(0, 0, 0, "dialog");
        return true;
    }
    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // TODO Auto-generated method stub
        switch(item.getItemId())
        {
        case 0:
            testDialog();
        }
        return super.onOptionsItemSelected(item);
    }
    @TargetApi(Build.VERSION_CODES.HONEYCOMB)
    @SuppressLint("NewApi")
    private void testDialog()
    {
        TestDialog td = TestDialog.newInstant("xia");
        FragmentManager fm = getFragmentManager();
        FragmentTransaction ft = fm.beginTransaction();
        td.show(ft, "Test Dialog");
    }
    public void onDialogDone(String tag, boolean cancel, CharSequence message)
    {
        String s = tag + "responds with : " + message;
        if(cancel)
        {
            s = tag + " was cancelled by the user";
        }
        Toast.makeText(this, s, Toast.LENGTH_LONG);
        Log.v("log_debug", s);
    }
}
