toggle() does not work

[penpens]

Hi I'm trying to toggle the layout from code, but it does not work.

Calling toggle() (not expanding):

Pressing on the header (and works fine):

My code:

public void addDynamicLayout(int count_p, String[] param) {
        final String nome = "PROGRAMMA " + String.valueOf(count_p);
        final ExpansionHeader expansionHeader = createExpansionHeader(count_p, nome);
        dynamicLayoutContainer.addView(expansionHeader, ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);

        final ExpansionLayout expansionLayout = createExpansionLayout(count_p, param);
        dynamicLayoutContainer.addView(expansionLayout, ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);

        expansionLayout.addListener(new ExpansionLayout.Listener() {
            @Override
            public void onExpansionChanged(ExpansionLayout expansionLayout, boolean expanded) {
                editorProg.putBoolean(nome, expansionHeader.isExpanded());
                editorProg.commit();
            }
        });

        boolean toggle = toggleProg.getBoolean(nome, false);

        if (toggle) {
            expansionLayout.toggle(true);
        }

        expansionHeader.setExpansionLayout(expansionLayout);
    }

Thanks in advance.

Not working. At the end, finally, I made an working workaround using performClick(). Anyway, thanks for the help.

findViewById(R.id.lay_sms).findViewWithTag("headerProg1").post(new Runnable() {
                            @Override
                            public void run() {
                                findViewById(R.id.lay_sms).findViewWithTag("headerProg1").performClick();
                            }
                        });
