Android支持庫ActionBar不工作在2.3設備

Question

你好朋友我實現了ActionBar支持庫與v7 Appcompact。我用ActionBarActivity擴展我的Activity類。下面是我的主類

import android.os.Bundle; 
import android.support.v7.app.ActionBarActivity; 
import android.support.v7.widget.SearchView; 
import android.view.Menu; 
import android.view.MenuItem; 

public class MainActivity extends ActionBarActivity { 

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

    getSupportActionBar().setDisplayHomeAsUpEnabled(true); 
} 

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    // Inflate the menu; this adds items to the action bar if it is present. 
    getMenuInflater().inflate(R.menu.activity_main, menu); 
    MenuItem menuItem=menu.findItem(R.id.menu_settings); 
    SearchView mSearchView=(SearchView)menuItem.getActionView(); 
    return super.onCreateOptionsMenu(menu); 
     } 

    } 

清單文件，我宣佈主題型這樣

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
package="com.example.appcompactdemo" 
android:versionCode="1" 
android:versionName="1.0" > 

<uses-sdk 
    android:minSdkVersion="8" 
    android:targetSdkVersion="16" /> 

<application 
    android:allowBackup="true" 
    android:icon="@drawable/ic_launcher" 
    android:label="@string/app_name" 
    android:theme="@style/AppTheme" > 
    <activity 
     android:name="com.example.appcompactdemo.MainActivity" 
     android:label="@string/app_name" 
     android:theme="@style/Theme.AppCompat.Light.DarkActionBar"> 
     <intent-filter> 
      <action android:name="android.intent.action.MAIN" /> 

      <category android:name="android.intent.category.LAUNCHER" /> 
     </intent-filter> 
    </activity> 
</application> 

在style.xml象下面這樣：

<style name="ExampleTheme" parent="Theme.AppCompat.Light.DarkActionBar"> 
    <item name="homeAsUpIndicator">@drawable/new_indicator</item> 
    <item name="android:homeAsUpIndicator">@drawable/new_indicator</item> 
    </style> 

上面的代碼工作與Android版本4.0罰款，但在2.3設備它不工作，它會給出錯誤，如：

java.lang.NoSuchMethodError: android.view.MenuItem.getActionView

所以任何想法我怎麼能解決它？

我想回答你的問題是official developers guide：

你應該申報的搜索小插件

<?xml version="1.0" encoding="utf-8"?> 
<menu xmlns:android="http://schemas.android.com/apk/res/android" 
     xmlns:yourapp="http://schemas.android.com/apk/res-auto" > 
    <item android:id="@+id/action_search" 
     android:title="@string/action_search" 
     android:icon="@drawable/ic_action_search" 
     yourapp:showAsAction="ifRoom|collapseActionView" 
     yourapp:actionViewClass="android.support.v7.widget.SearchView" /> 
</menu> 

如果您需要配置動作視圖（如添加事件偵聽器）您可以在onCreateOptionsMenu（）回調期間這樣做。您可以通過調用靜態方法MenuItemCompat.getActionView（）並向其傳遞相應的MenuItem來獲取操作視圖對象。例如，從上面的樣品的搜索小插件，獲取這樣的：

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    getMenuInflater().inflate(R.menu.main_activity_actions, menu); 
    MenuItem searchItem = menu.findItem(R.id.action_search); 
    SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem); // <-- change your code to this 
    // Configure the search info and add any event listeners 
    ... 
    return super.onCreateOptionsMenu(menu); 
}
