blocks|key|1907566|text|至少对我来说，将PreferenceActivity与ABC集成是不可能的。我尝试了我能找到的两种可能性，但都不起作用：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1907567|选项1：|1907568|ActionBarPreferenceActivity扩展了PreferenceActivity。当你这样做的时候，你会受到ActionBarActivityDelegate.createDelegate(ActionBarActivity+activity)的限制。此外，您还需要实现不可访问的ActionBar.Callbacks|1907569|选项2：|1907570|ActionBarPreferenceActivity扩展了ActionBarActivity。这种方法需要重写一个全新的PreferenceActivity，PreferenceManager，并且可能是PreferenceFragment，这意味着你需要访问像com.android.internal.util.XmlUtils这样的隐藏类。这个问题的解决方案只能来自于谷歌开发人员实现了一个可以添加到任何活动中的ActionBarWrapper。|1907571|如果你真的需要一个偏好活动，我现在的建议是ActionBarSherlock。|1907572|然而，我设法用here实现了它。|1907573|entityMap|0|LINK|mutability|MUTABLE|url|https://gist.github.com/mburumaxwell/8254359^0|8|I|0|0|0|R|U|I|1Q|1W|44|J|0|0|0|R|U|H|1P|I|28|H|2V|I|3O|Y|5T|G|0|L|H|0|7|4|0|0^^$0|@$1|2|3|4|5|6|7|Z|8|@$9|10|A|11|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|12|8|@]|D|@]|E|$]]|$1|H|3|I|5|6|7|13|8|@$9|14|A|15|B|C]|$9|16|A|17|B|C]|$9|18|A|19|B|C]|$9|1A|A|1B|B|C]]|D|@]|E|$]]|$1|J|3|K|5|6|7|1C|8|@]|D|@]|E|$]]|$1|L|3|M|5|6|7|1D|8|@$9|1E|A|1F|B|C]|$9|1G|A|1H|B|C]|$9|1I|A|1J|B|C]|$9|1K|A|1L|B|C]|$9|1M|A|1N|B|C]|$9|1O|A|1P|B|C]|$9|1Q|A|1R|B|C]]|D|@]|E|$]]|$1|N|3|O|5|6|7|1S|8|@$9|1T|A|1U|B|C]]|D|@]|E|$]]|$1|P|3|Q|5|6|7|1V|8|@]|D|@$9|1W|A|1X|1|1Y]]|E|$]]|$1|R|3|-4|5|6|7|1Z|8|@]|D|@]|E|$]]]|S|$T|$5|U|V|W|E|$X|Y]]]]

Integrating <code>PreferenceActivity</code> with ABC is not possible, at least for me. I tried the two possibilities I could find but none worked:

<h2>Option 1:</h2>

<code>ActionBarPreferenceActivity</code> extends <code>PreferenceActivity</code>. When you do this you get restricted by <code>ActionBarActivityDelegate.createDelegate(ActionBarActivity activity)</code>. Also you need to implement <code>ActionBar.Callbacks</code> which is not accessible

<h2>Option 2:</h2>

<code>ActionBarPreferenceActivity</code> extends <code>ActionBarActivity</code>. This approach requires rewriting a whole new <code>PreferenceActivity</code>, <code>PreferenceManager</code> and may be <code>PreferenceFragment</code> which means you need access to hidden classes like <code>com.android.internal.util.XmlUtils</code>
The solution to this can only come from Google devs implementing an <code>ActionBarWrapper</code> that can be added to any activity.

If you really need a preference activity, my advice for now is <code>ActionBarSherlock</code>.

However, I managed to implement it <a href="https://gist.github.com/mburumaxwell/8254359" rel="nofollow">here</a>.

blocks|key|1907647|text|我能够通过使用getActionBar()获得android.app.Actionbar。它首先返回一个空值...然后我转到清单并将主题更改为：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1907648|android:theme="@style/Theme.AppCompat"|code-block|syntax|javascript|1907649|然后我又可以使用actionbar了。我假设这只适用于特定的构建级别。因此，您可能需要检查内部版本号，或者检查返回的值是否为空。|1907650|这对我来说很好，因为我正在开发的应用程序是针对ICS/4.0%2B的。|1907651|entityMap^0|7|E|N|L|0|0|0|N|7|0^^$0|@$1|2|3|4|5|6|7|Q|8|@$9|R|A|S|B|C]|$9|T|A|U|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|V|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|W|8|@]|D|@]|E|$]]|$1|M|3|N|5|6|7|X|8|@$9|Y|A|Z|B|C]]|D|@]|E|$]]|$1|O|3|-4|5|6|7|10|8|@]|D|@]|E|$]]]|P|$]]

I was able to get <code>android.app.Actionbar</code> by using <code>getActionBar()</code>. It returned a null value at first... then I went to the manifest and changed the theme to:

<pre><code>android:theme="@style/Theme.AppCompat"</code></pre>

Then I was able to have the actionbar again. I'm assuming this will only work for certain build levels. So you might want to do a check for the build number or check if the value returned is null. 

It'll be fine for me because the app I'm working on is for <code>ICS/4.0</code>+.

EDIT: In appcompat-v7 22.1.0 Google added the AppCompatDelegate abstract class as a delegate you can use to extend AppCompat's support to any activity.

Use it like this:

<pre><code>...

import android.support.v7.app.AppCompatDelegate;
import android.support.v7.widget.Toolbar;
...

public class SettingsActivity extends PreferenceActivity {

 getDelegate().installViewFactory();
 getDelegate().onCreate(savedInstanceState);
 super.onCreate(savedInstanceState);
 }

 @Override
 protected void onPostCreate(Bundle savedInstanceState) {
 super.onPostCreate(savedInstanceState);
 getDelegate().onPostCreate(savedInstanceState);
 }

 public ActionBar getSupportActionBar() {
 return getDelegate().getSupportActionBar();
 }

 public void setSupportActionBar(@Nullable Toolbar toolbar) {
 getDelegate().setSupportActionBar(toolbar);
 }

 @Override
 public MenuInflater getMenuInflater() {
 return getDelegate().getMenuInflater();
 }

 @Override
 public void setContentView(@LayoutRes int layoutResID) {
 getDelegate().setContentView(layoutResID);
 }

 @Override
 public void setContentView(View view) {
 getDelegate().setContentView(view);
 }

 @Override
 public void setContentView(View view, ViewGroup.LayoutParams params) {
 getDelegate().setContentView(view, params);
 }

 @Override
 public void addContentView(View view, ViewGroup.LayoutParams params) {
 getDelegate().addContentView(view, params);
 }

 @Override

 super.onPostResume();
 getDelegate().onPostResume();
 }

 @Override

Now the official answer for this problem has been released. It is the <a href="http://developer.android.com/tools/support-library/features.html#v7-preference" rel="nofollow noreferrer">v7/v14 Preference Support</a> library. 

See <a href="https://stackoverflow.com/questions/32070186/how-to-use-the-v7-v14-preference-support-library">How to use the v7/v14 Preference Support library?</a> for the discussion how to use it.

Action Bar compatibility has been added into support library, revision 18. It now has <a href="https://developer.android.com/reference/android/support/v7/app/ActionBarActivity.html" rel="noreferrer"><code>ActionBarActivity</code></a> class for creating activities with Action Bar on older versions of Android.

Is there any way to add Action Bar from support library into <code>PreferenceActivity</code>?

Previously I used <a href="http://actionbarsherlock.com/" rel="noreferrer">ActionBarSherlock</a> and it has <code>SherlockPreferenceActivity</code>.

How to add Action Bar from support library into PreferenceActivity?

动作栏兼容性已经添加到支持库中，版本18。它现在有了类，用于在旧版本的安卓上创建带有动作栏的活动。有没有办法将支持库中的操作栏添加到PreferenceActivity中之前我用的是，它有SherlockPreferenceActivity__。
