android - 退出和重新进入应用程序时，带有edittext的Listview崩溃

Question

我在 viewpager 中有一个 Listfragment，该片段只包含

    @Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    Log.e("Starter", "Starter");
    View v = inflater.inflate(R.layout.chat, container, false);

    text = (EditText) v.findViewById(R.id.text);


    return v;

}

chat.xml 文件包含

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >

<ListView
    android:id="@android:id/list"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginBottom="45dp" >
</ListView>

<EditText
    android:id="@+id/text"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_alignParentLeft="true"
    android:layout_alignTop="@+id/button1"
    android:layout_toLeftOf="@+id/button1"
    android:ems="10"
    android:inputType="textMultiLine" >
</EditText>

<Button
    android:id="@+id/button1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_alignParentRight="true"
    android:text="Send" />

我可以按 EditText，键盘就会出现，如果我按后退按钮，它就会消失。当键盘升起或按下时，列表视图会改变大小。

所有这一切都很好，直到我按下主页按钮，等待一两秒钟，然后再次进入应用程序。然后我收到以下错误：

我在列表中没有任何位图，也没有任何会导致此错误的内容。在您退出应用程序、重新进入并单击 EditText 之前，这一切都有效。

如果有人知道为什么会发生这种情况，很高兴收到您的来信！
