Question

我正在弹出窗口中显示表情符号，就像来自this库的whatsapp一样。我创建了一个弹出窗口，在主要活动中显示它。点击按钮后，我制作了以下代码

button.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                View popUp = getLayoutInflater().inflate(R.layout.popup_item, null);
                window = new PopupWindow(getApplicationContext());
                window = new PopupWindow(popUp,LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT,true);
                window.setAnimationStyle(android.R.style.Animation_Activity);
                window.showAtLocation(popUp, Gravity.BOTTOM, 0, 0);
                window.setFocusable(true);
                window.setOutsideTouchable(true);
            }
        });

popup_item包含以下内容

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:emojicon="http://schemas.android.com/apk/res-auto"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
    tools:context="com.rockerhieu.emojicon.example.MainActivity$PlaceholderFragment" >

    <com.rockerhieu.emojicon.EmojiconTextView
        android:id="@+id/txtEmojicon"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"/>

    <com.rockerhieu.emojicon.EmojiconEditText
        android:id="@+id/editEmojicon"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        emojicon:emojiconSize="28sp" />

    <fragment
        android:id="@+id/emojicons"
        android:layout_width="fill_parent"
        android:layout_height="220dp"
        class="com.rockerhieu.emojicon.EmojiconsFragment" />

</LinearLayout>

显示以下错误。

我发现它的原因是嵌套片段。但不知道解决方案。请帮忙。我真的需要解决这个问题。我是android的新手。感谢。
