使用Sherlock ActionBar，片段Tab的，ViewPager，PreferenceActivity

Question

所以我有这种偏好活动，似乎无法弄清楚如何使这项工作，如果它可以做到。我的应用程序使用Sherlock Actionbar，View-pager和Fragment Tabs。我的所有标签都不是最后一个，这是我的PreferenceActivity。

public class Prefs extends SherlockPreferenceActivity implements 
    OnSharedPreferenceChangeListener { 

    public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    addPreferencesFromResource(R.xml.settings); 

    Preference customPref = (Preference) findPreference("clearcache"); 
    customPref 
      .setOnPreferenceClickListener(new OnPreferenceClickListener() { 

       public boolean onPreferenceClick(Preference preference) { 
        Toast.makeText(getBaseContext(), "Cache Cleared", 
          Toast.LENGTH_LONG).show(); 
        Webview.web.clearCache(true); 
        return false; 
       } 
      }); 

    Preference customerPref1 = (Preference) findPreference("intent1"); 
    customerPref1 
      .setOnPreferenceClickListener(new OnPreferenceClickListener() { 

       public boolean onPreferenceClick(Preference preference) { 
        Intent myIntent = new Intent(Prefs.this, Intent1.class); 
        Prefs.this.startActivity(myIntent); 
        return true; 
       } 
      }); 

这就是我的偏好活动设置。选择此选项卡时，主要问题如下。

任何想法的，例如，其他的建议，是能够做一个设置页，即使其他的例子，我的大部分设置都只是意图的其他活动。

Answer 1

您正在尝试加载活动来代替片段。这就是为什么它给出了一个例外。如果您的设置是简单的意图，则无需将其置于偏好活动中。只需扩展SherlockFragment并将代码放置在那里。
