Action Bar Sherlock + ListFragments + Fragments

Question

我有一个版本2.2中的片段兼容性问题。我使用“Sherlock Action Bar”创建操作栏，但我无法创建两个片段。我得到这个错误的所有时间：

我main_activity包含此：

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main.xml中包含此：

<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> 

和类 “LISTA” 和“Detalle “承认：

列表：

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);*/ 
     } 
    } 
} 

Detalle：

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); 
    } 
} 

我觉得把很多代码，但不是因为它是错误的。

非常感谢您的帮助。

Answer 1

我main_activity包含此：

请从Sherlock类继承，如SherlockActivity，如果你打算使用ActionBarSherlock。如果您还打算使用，请从SherlockFragmentActivity继承。

引述the ActionBarSherlock documentation：

在创建活动使用操作栏上的Android的所有版本，您必须声明你的活动扩展任何与“福尔摩斯”（例如启动活动课， SherlockActivity，SherlockFragmentActivity）。

Answer 2

为了与保持兼容碎片和ABS的工作，你必须扩展SherlockFragmentActivity

public class MainActivity extends SherlockFragmentActivity {
