Action Bar Sherlock未启动

Question

我的Android应用程序由于某种原因未启动。这是一个非常基本的应用程序。当我运行它时，它只是说它必须关闭，并且我逼着关闭。

import com.actionbarsherlock.app.ActionBar.Tab; 
import com.actionbarsherlock.app.ActionBar.TabListener; 
import com.actionbarsherlock.app.*; 
import com.actionbarsherlock.app.SherlockActivity; 
import com.actionbarsherlock.app.ActionBar; 
import com.actionbarsherlock.app.SherlockFragmentActivity; 

import android.os.Bundle; 
import android.support.v4.app.FragmentActivity; 
import android.support.v4.app.FragmentTransaction; 
import android.util.Log; 


public class MainActivity extends SherlockFragmentActivity implements TabListener{ 

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

     final ActionBar actionBar = getSupportActionBar(); 
     actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS); 

     Tab tabRed = actionBar.newTab(); 
     tabRed.setText("Red Side"); 
     // tabRed.setTabListener(new TabListener<TabFragment>(this, "tab1", TabFragment.class)); 
     Tab tabBlue = actionBar.newTab(); 
     tabBlue.setText("Blue Side"); 
     // tabBlue.setTabListener(new TabListener<TabFragment>(this, tabBlue, TabFragment.class)); 

     actionBar.addTab(tabRed); 
     actionBar.addTab(tabBlue); 


    } 

    @Override 
    public void onTabSelected(Tab tab, FragmentTransaction ft) { 
     Log.d("Main Activity", "tab " + String.valueOf(tab.getPosition()) + " clicked"); 

    } 

    @Override 
    public void onTabUnselected(Tab tab, FragmentTransaction ft) { 
     Log.d("Main Activity", "tab " + String.valueOf(tab.getPosition())+ " un-clicked"); 

    } 

    @Override 
    public void onTabReselected(Tab tab, FragmentTransaction ft) { 
     Log.d("Main Activity", "tab " + String.valueOf(tab.getPosition()) + " re-clicked"); 


    } 



} 

这是我的activity_main.xml，其中只有文字。我是否也必须在xml中设置操作栏？

<RelativeLayout 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" > 



    <TextView 
     android:id="@+id/textView1" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_centerHorizontal="true" 
     android:layout_centerVertical="true" 
     android:text="@string/hello_world" /> 

</RelativeLayout> 

的logcat的

Answer 1

每个标签页必须有一个TabListener，例如：

Tab tabRed = actionBar.newTab(); 
tabRed.setText("Red Side"); 
tabRed.setTabListener(this); 
actionBar.addTab(tabRed); 

// The same is true for tabBlue
