Here's my code (that creates the first, 'Create Tag', dialog):

final Dao<Tag, Integer> tagDao = getHelper().getTagDao();
final EditText input = new EditText(this);
input.setSingleLine(true);
input.setHint(R.string.create_tag_dialog_hint);
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setView(input);
builder.setTitle(getString(R.string.create_tag_dialog_title));
builder.setPositiveButton(
    getString(R.string.create_tag_dialog_positive),
    new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int whichButton) {
            String value = input.getText().toString().trim();
            Toast.makeText(getApplicationContext(), value, Toast.LENGTH_SHORT).show();
            Tag tag = new Tag(value);
            try {
                    tagDao.create(tag);
            } catch (SQLException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
builder.setNegativeButton(
    getString(R.string.create_tag_dialog_negative), null);
builder.show();
Sorry for the length of the post and thanks for any helpful comments.
Just sorted this myself. Using an instance of AlertDialog, you can specify setView and pass in spacing parameters. This will work.
final EditText input = new EditText(this);
AlertDialog alertDialog = new AlertDialog.Builder(this).create();
alertDialog.setTitle("Title");
alertDialog.setMessage("Message");
alertDialog.setView(input, 10, 0, 10, 0); // 10 spacing, left and right
alertDialog.setButton("OK", new OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        // Clicked
alertDialog.show();
Edit: I'm aware this question is old, but no solution was provided.
                Heads Up: alertDialog.setView(View, int, int, int, int); does not exist in the new android api versions.

                Builder.setView can only be called from within the same library group (groupId=androidx.appcompat)  Inspection info:This API has been flagged with a restriction that has not been met.

LinearLayout layout = new LinearLayout(this);
layout.setOrientation(LinearLayout.VERTICAL);
layout.setGravity(Gravity.CENTER_HORIZONTAL);
final EditText input = new EditText(this);
input.setSingleLine(true);
layout.setPadding(10, 0, 10, 0);
input.setHint("Hint");
layout.addView(input);
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setView(layout);
Moreover, setSingleLine is deprecated. You should use InputStyle.
                Thanks for the heads up on the deprecation of SingleLine.  They don't mention it everywhere in the documentation.  Still, it doesn't seem like I should have to pick some number of pixels to correct this.  I am assuming that the present result is incorrect because of my misuse of AlertDialog.Builder (or perhaps it is entirely the wrong technique).

                I'm not exactly sure how to apply that...  but despite sp not being px, it would still be me arbitrarily setting some spacing rather than letting android use a default spacing.  I don't want to adjust the layout to my personal preference, I want Android to do it to it's preference.

                Padding applies to things inside of the view so EditText.setPadding() creates space around the text inside of the EditText.  I did try ((View) input.getParent()).setPadding(10, 10, 10, 10) after builder.setView(input), but this resulted in a null pointer exception.  Regardless, I don't want to find a way to customize it to my personal preference of 5px or such, I want to allow the SDK to format it correctly.  I assume I am using the SDK incorrectly and thus the formatting doesn't look right.
