android activitygroup with tabhost, keyboard not showing

Question

I have a tabhost and for each tab i have a activitygroup.

When the app starts and i press on a editText the keyboard comes out. When i start a child activity and then go back to the main activity the keyboard doesnt come out anymore.

My code for starting the the subactivity

Intent i = new Intent(this, ShowAddFoodToSelection.class).addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

View view = ActivityGroupMeal.group.getLocalActivityManager().startActivity(DataParser.activityIDMeal, i).getDecorView();

ActivityGroupMeal.group.setContentView(view);

my code to go back to the main activity

ActivityGroupMeal.group.back();

And the back code in the activitygroup:

public void back() {
        try {
            // if we set history.size() > 0 and we press back key on home
            // activity
            // and then on another activity we wont get back!
            if (history.size() > 1) {
                history.remove(history.size() - 1);
                // call the super.setContent view! so set the real view
                super.setContentView(history.get(history.size() - 1));
            } else {

            }
        } catch (Exception e) {
            if (history.size() >= 0)
                super.setContentView(history.get(0));
        }
    }

i set a onClickListener on the editText with the folowing code:

private void keyboardShow() {
        InputMethodManager inputManager = (InputMethodManager) ActivityGroupMeal.group.getSystemService(Context.INPUT_METHOD_SERVICE);

        boolean test = inputManager.showSoftInput(editTextSearch, InputMethodManager.SHOW_IMPLICIT);

        Toast.makeText(this, "show keyboard " + test, Toast.LENGTH_SHORT).show();
    }

The first time it returns true and the time i come back from a childactivity it returns false.

When i click on a other tab and then back on the first tab, and then i click on the editText it returns true again.

Edit: i got a temporary fix, i set a onClicklistener on the editTextbox and then there i show the keyboard with code

InputMethodManager inputManager = (InputMethodManager) ActivityGroupMeal.group
                .getSystemService(Context.INPUT_METHOD_SERVICE);

        // show keyboard , when it fails first switch tab and then try again
        if (!inputManager.showSoftInput(null, InputMethodManager.SHOW_FORCED)) {
            // switch from tab and back
            // the keyboard wont show if we dont do this
            ShowHomeTab parentActivity;
            parentActivity = (ShowHomeTab) this.getParent().getParent();
            parentActivity.goToTab(DataParser.activityIDTracking);
            parentActivity.goToTab(DataParser.activityIDShowFoodList);

            inputManager.showSoftInput(null, InputMethodManager.SHOW_FORCED);
        }

When i come back from the childactivity i first have to switch tabs with code before the keyboard will show =/

anyone got a explanation for that ?

In my application where I used Activity Group, I used below code to resolve the same issue

YOUR_EDIT_TEXT.setOnEditorActionListener(new OnEditorActionListener() {

            public boolean onEditorAction(TextView v, int actionId,
                    KeyEvent event) {
                if (event != null&& (event.getKeyCode() == KeyEvent.KEYCODE_ENTER)) {
                    InputMethodManager in = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
                    in.hideSoftInputFromWindow(searchName
                            .getApplicationWindowToken(),
                            InputMethodManager.HIDE_NOT_ALWAYS);
                }
                return false;
            }
        });

and it was working fine. So try out this code snippet.
