实现Android键盘与popupwindow

Question

表情符号，我已经开发了一个键盘，现在我需要表情符号吧，其他的问题我已经意识到最好的办法是与popupwindow，

这里就是我完成：

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); 

不幸的是，这并不工作，showAsDropDown需要一个视图作为其第一个变种，如果键盘是另一个应用程序，我没有一个视图给他......

有没有办法解决这个问题？ 或者我是否全都错了，还有更好的方法...

所有帮助将不胜感激！

Answer 1

既然你使用的是官方SoftKeyBoard implementation为你的键盘模板：

//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); 

使用已膨胀为你的键盘来看，在官方SoftKeyBoard和它上面的片段被称为mInputView。

您好，我已经做了同样的事情，这GitHub的链接。我在android中创建了一个自定义键盘。

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))

    emojiAdapter = new EmoticonsPagerAdapter(acitiviy, groups[0],

    pager.setAdapter(emojiAdapter); 

    // Creating a pop window for emoticons keyboard 
    popupWindow = new PopupWindow(popUpView, LayoutParams.MATCH_PARENT, 
      (int) keyboardHeight, false);

        0, 0, 0, KeyEvent.KEYCODE_ENDCALL); 
      editMessage.dispatchKeyEvent(event); 
     }
