Implement emojis in android keyboard with popupwindow

Question

I've developed a keyboard and now i need to add emojis to it , from other questions i've realized the best way is with popupwindow,

Here's what i've done:

  case -102:
            LayoutInflater layoutInflater
                    = (LayoutInflater)getBaseContext()
                    .getSystemService(LAYOUT_INFLATER_SERVICE);
            View popupView = layoutInflater.inflate(R.layout.emoji_view, null);
            final PopupWindow popupWindow = new PopupWindow(
                    popupView,
                    LinearLayout.LayoutParams.MATCH_PARENT,
                    LinearLayout.LayoutParams.MATCH_PARENT);
            popupWindow.showAsDropDown(getWindow().getOwnerActivity().getCurrentFocus(),50, -30);

Unfortunatly this doesn't work , showAsDropDown needs a view as its first var , and if the keyboard is in another app i don't have a view to give him...

Is there a way to fix that ? or am i going about it all wrong and there is a better way...

all help will be appreciated!

hi i have done same things. I have made one custom keyboard in android.

EmoticonsPagerAdapter emojiAdapter;

/**
 * Defining all components of emoticons keyboard
 */
private void enablePopUpView() {

    final ViewPager pager = (ViewPager) popUpView
            .findViewById(R.id.emoticons_pager);
    pager.setOffscreenPageLimit(3);

    final ArrayList<EmojiItem> paths = EmojiUtil.getInstance(acitiviy)
            .getAllEmojis();
    final ArrayList<EmojiItem>[] groups = new ArrayList[5];
    for (EmojiItem emoji : paths) {
        if (groups[emoji.emojiGroup] == null) {
            groups[emoji.emojiGroup] = new ArrayList<EmojiItem>();
        }
        groups[emoji.emojiGroup].add(emoji);
    }
    final ArrayList<EmojiItem> history = new ArrayList<EmojiItem>();
    ArrayList<Integer> historyIds = SettingsUtil.getHistoryItems(acitiviy);
    for (Integer his : historyIds) {
        for (EmojiItem emoji : paths) {
            if (emoji.id == his) {
                history.add(emoji);
                break;
            }
        }
    }
    history.add(paths.get(0));

    final KeyClickListener onEmojiClick = new KeyClickListener() {

        @Override
        public void keyClickedIndex(EmojiItem index) {

            int cursorPosition = editMessage.getSelectionStart();
            editMessage.getText().insert(cursorPosition, index.emojiText);
            try {
                editMessage.getText().setSpan(
                        new ImageSpan(index.emojiDrawable), cursorPosition,
                        cursorPosition + 1,
                        Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
            } catch (Exception e) {
            }
            if (history.get(0) != index)
                history.add(0, index);
            SettingsUtil.setHistoryItems(acitiviy, history);
            emojiAdapter.notifyDataSetChanged();
            pager.setAdapter(emojiAdapter);
        }
    };

    ((ImageButton) popUpView.findViewById(R.id.emoji2))

Answer 3

Given that you are using the official SoftKeyBoard implementation as a template for your keyboard:

//Cut some pieces of the code for clarity
case -102:
    LayoutInflater layoutInflater = (LayoutInflater)getBaseContext()
        .getSystemService(LAYOUT_INFLATER_SERVICE);
    View popupView = layoutInflater.inflate(R.layout.emoji_view, null);
    PopupWindow popupWindow = new PopupWindow(popupView, MATCH_PARENT, MATCH_PARENT);
    popupWindow.showAsDropDown(mInputView);

Use the view that you have inflated for your keyboard, in the offical SoftKeyBoard and the snippet above it is called mInputView.
