Question

I currently have a custom Dialog class that extends DialogPreference(which of course is a part of a PreferenceScreen).

This Dialog have custom buttons which handles save and cancel. Therefor i would like to get rid of the standard “positive” and “negative” buttons.

Tried using AlertDialog getButton method but no success.

Answer 1

in your xml use the following instead of DialogPreference:

<Preference
    android:title="This acts as a button"
    android:key="button"
    android:summary="This can act like a button to create it's own dialog"/>

Then in the java:

Preference button = (Preference)findPreference("button");
button.setOnPreferenceClickListener(new Preference.OnPreferenceClickListener() {

            @Override
            public boolean onPreferenceClick(Preference arg0) {
                showDialog(MY_DIALOG); // let's say MY_DIALOG is 'final int MY_DIALOG = 1;' in the class body
                return false;
            }
        });

Then add to your class body:

@Override
    protected Dialog onCreateDialog(int id) {

    switch (id) {       

    case SHOW_APP_STRING:
      LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
      View mylayout = inflater.inflate(R.layout.mylayout, null);


     final AlertDialog myDialog = new AlertDialog.Builder(this)
     .setView(mylayout)
     .show();
      //The buttons are below the dialog so you can close the dialog within your button listeners
      Button save = (Button)myLayout.findViewById(R.id.save);
      Button cancel = (Button)myLayout.findViewById(R.id.cancel);
      //set onClickListeners for both of your buttons

      return myDialog;
    }

}

I’m not sure if this is the best method, but it’s how I do it, and it works.
