java.lang.IllegalArgumentException異常：未找到片段

Question

我在Android聊天信使。我已經包含。對點擊的ImageView的ImageView的一個活動，一個對話框，將成爲對話打開.Layout工作的看法是：

emoji.xml

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="vertical"> 

    <FrameLayout 
     android:id="@+id/emojicon" 
     android:layout_width="match_parent" 
     android:layout_height="50dp" /> 

</LinearLayout> 

代碼處理圖像點擊

imageView.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      hideKeyboard(); // hiding the keyboard 
      // showEmojiPopUp(!showEmoji); 
      Dialog dialog = new Dialog(ChatActivity.this); 
      dialog.setContentView(R.layout.emoji); 
      getSupportFragmentManager().beginTransaction().replace(R.id.emojicon, EmojiconsFragment.newInstance(false)).commit(); 
      dialog.show(); 
     } 
    }); 

在點擊圖像視圖時，我創建了一個包含FrameLayout的對話框。在這裏，EmojiFragment將創建一個表情符號面板，並且Emoji.xml中的FrameLayout將被EmojiFragment替換。但在這裏我得到了下面提到的錯誤：

java.lang.IllegalArgumentException: No view found for id 0x7f0c004b (com.almabay.almachat:id/emojicon) for fragment EmojiconsFragment{429a7f68 #1 id=0x7f0c004b}

請幫我解決它。

這是顯示自定義對話框的示例。自定義是xml佈局這裏

final Dialog dialog = new Dialog(context); 
      dialog.setContentView(R.layout.custom); 
      dialog.setTitle("Title..."); 

      // set the custom dialog components - text, image and button 
      TextView text = (TextView) dialog.findViewById(R.id.text); 
      text.setText("Android custom dialog example!"); 
      ImageView image = (ImageView) dialog.findViewById(R.id.image); 
      image.setImageResource(R.drawable.ic_launcher); 

      Button dialogButton = (Button) dialog.findViewById(R.id.dialogButtonOK); 
      // if button is clicked, close the custom dialog 
      dialogButton.setOnClickListener(new OnClickListener() { 
       @Override 
       public void onClick(View v) { 
        dialog.dismiss(); 
       } 
      }); 

      dialog.show(); 
      } 

我希望這會有所幫助。
