Dialog buttons with long text not wrapping / squeezed out - material theme on android 5.0 lollipop

Question

While optimizing an app for material theme on lollipop, I\'m encountering this annoying problem:

Whenever there is long text on dialog buttons, that doesn\'t fit the but

Here is a workaround I came up with, with the help of the linked answer from Andrey T (https://stackoverflow.com/a/29662638/1317564):

First, you create an utility method which will wrap the buttons only if they need to be wrapped:

public static void applyWorkaroundForButtonWidthsTooWide(Button dialogButton) {
        if (dialogButton == null)
            return;
        if (!(dialogButton.getParent() instanceof LinearLayout))
            return;            

        // Workaround for buttons too large in alternate languages.
        final LinearLayout linearLayout = (LinearLayout) dialogButton.getParent();
        linearLayout.addOnLayoutChangeListener(new View.OnLayoutChangeListener() {
            @Override
            public void onLayoutChange(View v, int left, int top, int right, int bottom, int oldLeft, int oldTop,
                                       int oldRight, int oldBottom) {
                if (right - left > 0) {
                    final int parentWidth = linearLayout.getWidth();
                    int childrenWidth = 0;
                    for (int i = 0; i < linearLayout.getChildCount(); ++i)
                        childrenWidth += linearLayout.getChildAt(i).getWidth();

                    if (childrenWidth > parentWidth) {
                        // Apply stacked buttons
                        linearLayout.setOrientation(LinearLayout.VERTICAL);
                        linearLayout.setPadding(linearLayout.getPaddingLeft(), 0, linearLayout.getPaddingRight(),
                                linearLayout.getPaddingBottom());
                        for (int i = 0; i < linearLayout.getChildCount(); ++i) {
                            if (linearLayout.getChildAt(i) instanceof Button) {
                                final Button child = (Button) linearLayout.getChildAt(i);
                                child.setGravity(Gravity.END | Gravity.CENTER_VERTICAL);
                                final LinearLayout.LayoutParams params = (LinearLayout.LayoutParams) child.getLayoutParams();
                                params.width = LinearLayout.LayoutParams.MATCH_PARENT;
                                params.gravity = Gravity.END;
                                child.setLayoutParams(params);
                            } else if (linearLayout.getChildAt(i) instanceof Space) {
                                linearLayout.removeViewAt(i--);
                            }
                        }
                    }

                    linearLayout.removeOnLayoutChangeListener(this);
                }
            }
        });
    }

You can add additional error handing (i.e. try/catches) and customize this further as appropriate.

Now, you call this utility method when the dialog is shown:

dialog.setOnShowListener(new DialogInterface.OnShowListener() {
                @Override
                public void onShow(DialogInterface dialogInterface) {
                    MaterialAlertDialogUtils.applyWorkaroundForButtonWidthsTooWide(dialog.getButton(AlertDialog.BUTTON_POSITIVE));
                }
            });

This does the trick and will only wrap the buttons if needed. I've been using it everywhere, as even two-button dialogs may need wrapping in German and three-button dialogs surely need it in many languages.
