我对 2.2 版中的片段的兼容性有疑问。我使用“Sherlock Action Bar”来创建操作栏，但我无法创建两个片段。我一直收到这个错误：

我的 main_activity 包含以下内容：

package com.example.pruebasherlock_v4;

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

public class MainActivity extends Activity {

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

我的 main.xml 包含以下内容：

<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"
    tools:context=".MainActivity" >

    <fragment 
        android:id="@+id/listaIzq"
        android:layout_weight="1"
        android:layout_width="0dp"
        android:layout_height="fill_parent" 
        class="com.example.pruebasherlock_v4.Lista"/>

    <fragment 
        android:id="@+id/detallesDer"
        android:layout_weight="3"
        android:layout_width="0dp"
        android:layout_height="fill_parent"
        class="com.example.pruebasherlock_v4.Detalle" />


</LinearLayout>

而“lista”和“Detalle”类包含以下内容：

清单：

package com.example.pruebasherlock_v4;

import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;

import com.actionbarsherlock.app.SherlockListFragment;

public class Lista extends SherlockListFragment{
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState); 
    }

    @Override
    //se sobreescribe este método como el que siempre "carga" la información a mostrar en el fragment
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        String[] values = new String[] { "Android", "iPhone", "WindowsMobile",
        "Blackberry", "WebOS", "Ubuntu", "Windows7", "Max OS X",
        "Linux", "OS/2" };
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this.getActivity(), android.R.layout.simple_list_item_1, values);

        setListAdapter(adapter);
    }

    @Override
    //al hacer tap en algun elemento de la vista, setea el texto del elemento en el nuevo fragment
    public void onListItemClick(ListView l, View v, int position, long id) {
        String item = (String) getListAdapter().getItem(position);
        Detalle fragment = (Detalle) getFragmentManager().findFragmentById(R.id.detallesDer);
        if (fragment != null && fragment.isInLayout()) {
            fragment.setText(item);
        } else {
            /*Intent intent = new Intent(getActivity().getApplicationContext(), DetailActivity.class);
            intent.putExtra("value", item);
            startActivity(intent);*/
        }
    }
}

细节：

package com.example.pruebasherlock_v4;

import android.os.Bundle;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;

import com.actionbarsherlock.app.SherlockFragment;

public class Detalle extends SherlockFragment {
    @Override
    public void onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
        Log.e("Test", "hello");
    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);     
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.detalle, container, false);
        return view;
    }

    public void setText(String item) {
        TextView view = (TextView) getView().findViewById(R.id.textoDetalle);
        view.setText(item);
    }
}

我觉得放了很多代码，但不是因为它是错误的。

非常感谢您的帮助。

我的 main_activity 包含以下内容：

如果您打算使用 ActionBarSherlock，请从Sherlock类继承，例如。SherlockActivity如果你也打算使用片段，请继承自SherlockFragmentActivity.

引用ActionBarSherlock 文档：

在创建活动以在所有版本的 Android 上使用操作栏时，您必须声明您的活动以扩展任何以“Sherlock”开头的活动类（例如，SherlockActivity、SherlockFragmentActivity）。

为了使用兼容性片段和 ABS，您必须扩展 SherlockFragmentActivity

public class MainActivity extends SherlockFragmentActivity {
