java - PreferenceActivity 中的工具栏设置

Question

我正在尝试使用以下代码在首选项活动中设置工具栏。它确实显示了工具栏，但它覆盖了首选项列表。 这 是来自我的应用程序的屏幕截图链接，我正在执行此操作，因为我在运行时更改了样式主题。我已经在其他活动中实现了它，但我也希望它用于 PreferenceActivity。

设置活动

    public class SettingsActivity extends PreferenceActivity
{
    private AppCompatDelegate mDelegate;


    @Override
    protected void onCreate(Bundle savedInstanceState)
    {


        getDelegate().installViewFactory();
        getDelegate().onCreate(savedInstanceState);
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_settings);
        setSupportActionBar((Toolbar) findViewById(R.id.toolbarsettings));
        getFragmentManager().beginTransaction().replace(android.R.id.content, new MainPrefernceFragment()).commit();

    }



    @Override
    public boolean onOptionsItemSelected(MenuItem item)
    {


        if (item.getItemId() == android.R.id.home)
        {
            onBackPressed();
        }
        return super.onOptionsItemSelected(item);
    }

    @Override
    public void onBackPressed()
    {
        finish();
        super.onBackPressed();
    }






    public static class MainPrefernceFragment extends PreferenceFragment
    {

        @Override
        public void onCreate(Bundle savedInstanceState)
        {
            super.onCreate(savedInstanceState);
            addPreferencesFromResource(R.xml.preferences);

        }

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

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

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

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

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

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

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

}

好的，我得到了最终的解决方案 activity_settings.xml

<RelativeLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    xmlns:app="http://schemas.android.com/apk/res-auto" 
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.nanosoft.icstudio.SettingsActivity">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbarsettings"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"/>



    <FrameLayout 
        android:id="@+id/fragment_container"
        android:layout_width="match_parent"
        android:layout_marginTop="?attr/actionBarSize"
        android:layout_height="match_parent" >


    <ListView 
        android:id="@android:id/list" 
        android:layout_width="match_parent" 
        android:layout_height="wrap_content" />
    </FrameLayout>

</RelativeLayout>

java类SettingsActivity的一些变化

getFragmentManager().beginTransaction().replace(R.id.fragment_container, new MainPrefernceFragment()).commit();
