操作栏的兼容性已经被加入到支持库，修订18.现在有ActionBarActivity类在旧版本的Andr​​oid创建与行动吧。

Action Bar compatibility has been added into support library, revision 18. It now has ActionBarActivity class for creating activities with Action Bar on older versions of Android.

有没有办法从支持库中添加动作栏为 preferenceActivity ？

Is there any way to add Action Bar from support library into PreferenceActivity?

previously我用 ActionBarSherlock 并具有福尔摩斯preferenceActivity 。的

Previously I used ActionBarSherlock and it has SherlockPreferenceActivity.

推荐答案

编辑：在appcompat-V7 22.1.0谷歌增加了AppCompatDelegate抽象类作为一个代表，你可以用它来AppCompat的支持扩展到任何活动

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.

使用这样的：

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

public class SettingsActivity extends PreferenceActivity {

    private AppCompatDelegate mDelegate;

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

    @Override
    protected void onTitleChanged(CharSequence title, int color) {
        super.onTitleChanged(title, color);
        getDelegate().setTitle(title);
    }

    @Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
        getDelegate().onConfigurationChanged(newConfig);
    }

    @Override
    protected void onStop() {
        super.onStop();
        getDelegate().onStop();
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        getDelegate().onDestroy();
    }

    public void invalidateOptionsMenu() {
        getDelegate().invalidateOptionsMenu();
    }

    private AppCompatDelegate getDelegate() {
        if (mDelegate == null) {
            mDelegate = AppCompatDelegate.create(this, null);
        }
        return mDelegate;
    }
}

没有更多的黑客攻击。 code摘自AppCompat$p$pferenceActivity.java.

No more hacking. Code taken from AppCompatPreferenceActivity.java.
