我写了我的自定义视图，它由TextView和EditText组成LinearLayout。

但是Orientation Change我得到这个错误：

x_edittext_view.xml布局：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">

<TextView
    android:id="@+id/label"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_gravity="center_vertical"
    android:layout_weight="@dimen/textLabel_weight" />

<EditText
    android:id="@+id/input"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_weight="@dimen/inputView_weight" />

</LinearLayout>

在主布局中：

<LinearLayout
        android:id="@+id/linear"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">

        <ge.altasoft.custom_views.XEditText
            android:id="@+id/first_name"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:inputType="phone"
            custom:textLabel="სახელი"
            custom:viewParameter="opaaa"/>
</LinearLayout>

我想，这个问题TextView在我的CustomView课堂上。我将TextView文本XEditText作为自定义传递Attribute，然后在XEditText创建过程中进行设置。但我不确定这是否是问题所在。

编辑 1： 关于我的主要活动：我正在使用 ViewPager，这是我使用此布局的片段：

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import java.io.Serializable;
import java.util.ArrayList;
import ge.altasoft.Item.DetailsItemI;
import ge.altasoft.controllers.ViewFillerController;

public class OrdinaryFragment extends Fragment implements Serializable{
    private static final String LAYOUT_ID = "LayoutId";
    private int layoutId;

    public static final String ARG_SECTION_NUMBER = "section_number";

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    this.setRetainInstance(true);
    layoutId = getArguments().getInt(LAYOUT_ID);

    View rootView = inflater.inflate(layoutId, container, false);

    ArrayList<DetailsItemI> list = (ArrayList<DetailsItemI>)getArguments().getSerializable("ViewData");
    ViewFillerController viewFiller = new ViewFillerController();
    viewFiller.fillTheView(rootView, list);

    return rootView;
}

}

感谢Advnace。

我找到了Solution我的问题。

Bad Cast正如Error告诉我的那样，问题出在 中。

正如我所说，我有很多Custom Views，所有这些都由 2 个组件组成：TextView还有一些Input Type View. 尽管它是类型，但所有TextViews和所有都Input Type Views具有相同的Id-s。

例如，如果我有 2和Custom Views，则在 android 试图改变方向时应用程序崩溃了。EditText TypeSpinner Typecast editText SavedStateSpinner SavedState

所以我只是改变了Id-s，一切都很顺利。

谢谢大家，你们的帮助。
