如何将焦点从WhatsApp编辑字段更改为在自定义键盘中实现的自定义编辑字段？

Question

我为贴纸应用创建了自定义键盘。它具有搜索贴纸并在WhatsApp，Facebook等上共享的功能。 但是我的问题是，我无法在键盘内将焦点从WhatsApp编辑字段更改为自定义edittext。 当前，当我尝试触摸键盘中实现的编辑文本并在其中写入一些文本时，它会自动在默认的WhatsApp编辑字段中进行编辑，而不会在自定义编辑文本中进行编辑。

任何解决方案...

这是我的代码。

keyboard_view.setOnKeyboardActionListener(new KeyboardView.OnKeyboardActionListener() {
        @Override
        public void onPress(int i) {
        }

        @Override
        public void onRelease(int i) {

        }

        @Override
        public void onKey(int primaryCode, int[] ints) {
            InputConnection ic = getCurrentInputConnection();
            playClick(primaryCode);
            switch (primaryCode) {
                case Keyboard.KEYCODE_DELETE:
                    getCurrentInputConnection().sendKeyEvent(new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_DEL));
                    break;
                case Keyboard.KEYCODE_SHIFT:
                    caps = !caps;
                    keyboard.setShifted(caps);
                    keyboard_view.invalidateAllKeys();
                    break;
                case android.inputmethodservice.Keyboard.KEYCODE_DONE:
                    if (isSearched){
                        searchQuery();
                        frame_contain.setVisibility(View.GONE);
                        frame_container_search.setVisibility(View.VISIBLE);
                        keyboard_view.setVisibility(View.GONE);
                        search_view_items.setVisibility(View.VISIBLE);
                        callAdapterForSearchedStickers();
                        isSearched = false;
                        break;

                        ic.sendKeyEvent(new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_ENTER));
                        ic.sendKeyEvent(new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_ENTER));
