使用ONLY AppCompat可以实现这一点，请检查我的解决方法：

    import android.support.v7.app.AlertDialog;

    AlertDialog.Builder builder;
    builder = new AlertDialog.Builder(context, R.style.StackedAlertDialogStyle);
    builder.setTitle("Title");
    builder.setMessage("Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nunc dignissim purus eget gravida mollis. Integer in auctor turpis. Morbi auctor, diam eget vestibulum congue, quam arcu pulvinar dui, blandit egestas erat enim non ligula." +
            " Nunc quis laoreet libero. Aliquam consectetur nibh eu arcu eleifend efficitur.");
    builder.setPositiveButton("Positive Button", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
        }
    });
    builder.setNeutralButton("Neutral Button", new DialogInterface.OnClickListener() {
        @Override

    });
    builder.setNegativeButton("Cancel Button", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
        }
    });
    AlertDialog alertDialog = builder.create();
    alertDialog.show();
        try{
            final Button button = alertDialog.getButton(AlertDialog.BUTTON_POSITIVE);
            LinearLayout linearLayout = (LinearLayout) button.getParent();
            linearLayout.setOrientation(LinearLayout.VERTICAL);
        } catch(Exception ex){
            //ignore it
        }

<style name="StackedAlertDialogStyle" parent="Theme.AppCompat.Light.Dialog.Alert">
    <item name="buttonBarButtonStyle">@style/StackedButtonBarButtonStyle</item>

<style name="StackedButtonBarButtonStyle" parent="Widget.AppCompat.Button.ButtonBar.AlertDialog">

以下是我使用ONLY AppCompat库在我的应用中的表现 您可以选择任意数量的

String[] mOptionsArray = new String[]{"Option 1", "Option 2"};
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    AlertDialog.Builder builder = new AlertDialog.Builder(getContext());
    builder.setTitle("Cool! title");
    builder.setMessage("Cool! message");

    LayoutInflater inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View view = inflater.inflate(R.layout.dialog_list_view, null);
    ListView listView = (ListView) view.findViewById(R.id.list_view);
    listView.setAdapter(new ArrayAdapter<>(
            getContext(),
            R.layout.dialog_list_item,
            R.id.button,
            mOptionsArray
    ));
    listView.setDivider(null);
    listView.setOnItemClickListener(mOnItemClickListener);
    builder.setView(view);

    return builder.create();
}

<强> dialog_list_view.xml

<?xml version="1.0" encoding="utf-8"?>
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/list_view"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:paddingBottom="8dp"
    android:paddingLeft="16dp"
    android:paddingRight="16dp" />

<强> dialog_list_item.xml

<?xml version="1.0" encoding="utf-8"?>
<Button xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/button"
    style="@style/Widget.AppCompat.Button.Borderless.Colored"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@null"
    android:clickable="false"
    android:focusable="false"
    android:gravity="right|center_vertical"
    android:paddingRight="8dp"
    android:paddingLeft="8dp"
    android:text="Button"
    android:textAllCaps="true" />

如果按钮上包含长消息文本，这是自动的。

new MaterialAlertDialogBuilder(this)
                .setTitle("Title")
                .setMessage(R.string.lorem_inpsum)
                .setPositiveButton(getResources().getString(R.string.long_positive), null)
                .setNegativeButton(getResources().getString(R.string.long_negative), null)
                .show();
