Android - DialogFrame中的中心文字

Question

如何将dialog_more_information集中在以下代码中？是否有必要使用自定义视图？

提前致谢！

这就是我所说的＆gt;

@Override
public boolean onOptionsItemSelected(MenuItem item) {

    switch (item.getItemId()) {
    case R.id.more_information:
        MoreInformationDialogFragment mDialog = new MoreInformationDialogFragment();
        mDialog.show(getFragmentManager(), null);

        return true;
    default:
        return false;
    }
}

这是MoreInformationDialogFragment类＆gt;

public class MoreInformationDialogFragment extends DialogFragment {

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState){
        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
        builder.setMessage(R.string.dialog_more_information)
            .setPositiveButton(R.string.dialog_visit_moma, new DialogInterface.OnClickListener() {
               public void onClick(DialogInterface dialog, int id) {
                   Uri uri = Uri.parse("http://www.somesite.org");
                   Intent SomeSite = new Intent(Intent.ACTION_VIEW, uri);
                   startActivity(SomeSite);
               }
           })
           .setNegativeButton(R.string.dialog_cancel, new DialogInterface.OnClickListener() {
               public void onClick(DialogInterface dialog, int id) {
                   // Cancel
                   setResult(RESULT_CANCELED); // is this really needed?
               }
           });

        return builder.create();
    }
}

以下是如何做到的：

Dialog dialog = builder.create();
TextView messageText = (TextView)dialog.findViewById(android.R.id.message);
messageText.setGravity(Gravity.CENTER);
return dialog;
