HoloEverywhere AutoCompleteTextView java.lang.ClassCastException

Question

我想让HoloEverywhere类AutoCompleteTextView与我的应用程序一起工作。造成这种情况的主要原因是我想要的河洛主题预3.0设备（特别是API等级8-10）在这里工作是我的主要活动代码：

package com.example.testautocomp; 

import org.holoeverywhere.widget.AutoCompleteTextView; 

import android.app.Activity; 
import android.os.Bundle; 
import android.widget.ArrayAdapter; 

public class MainActivity extends Activity { 

    private AutoCompleteTextView m_edit; 

    private static final String[] items = { "lorem", "ipsum", "dolor", "sit", 
     "amet", "consectetuer", "adipiscing", "elit", "morbi", "vel", 
     "augue", "purus", "sitter", "sitting", "sither", "sithar" }; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    m_edit = (AutoCompleteTextView)findViewById(R.id.edit2); 

    m_edit.setAdapter(new ArrayAdapter<String>(this, 
      android.R.layout.simple_dropdown_item_1line, items)); 
    } 
} 

也是我activity_main.xml中代码：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:orientation="vertical" > 

<AutoCompleteTextView 
    android:id="@+id/edit2" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:completionThreshold="1" 
    android:hint="Testing" /> 
</LinearLayout> 

当我运行我的应用程序，它进入调试器Eclipse和紧迫简历（或F8）继续线程后，我的应用程序崩溃/强制关闭，我得到了我的logcat以下错误：

我如何解决这个CastClassException？

Answer 1

非常相似，这question

通过改变我的main_activity.xml到固定它：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:orientation="vertical" > 

<org.holoeverywhere.widget.AutoCompleteTextView 
    android:id="@+id/edit2" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:completionThreshold="1" 
    android:hint="Testing" /> 
</LinearLayout> 

主要部分是org.holoeverywhere.widget.AutoCompleteTextView

Answer 2

不，你的以上操作不正确。您应该更改org.holoeverywhere.app.Activity上的活动基类。
