java - 未调用设置 Activity onCreate()

Question

在按下“设置”时，我只看到一个普通的白色屏幕，布局没有被覆盖，所以我设置了断点来检查发生了什么。该类被调用，但 onCreate() 没有被调用。

这是代码-

public class SettingsActivity extends AppCompatActivity {

    @InjectView(R.id.settings_toolbar) Toolbar toolbar;

    @Override
    public void onCreate(Bundle savedInstanceState, PersistableBundle persistentState) {
        super.onCreate(savedInstanceState, persistentState);
        setContentView(R.layout.settings_toolbar);
        ButterKnife.inject(this);
        setSupportActionBar(toolbar);
        getFragmentManager().beginTransaction().
            replace(R.id.content_frame, new MyPreferenceFragment()).commit();
    }

    public static class MyPreferenceFragment extends PreferenceFragment {
        @Override
        public void onCreate(final Bundle savedInstanceState){
            super.onCreate(savedInstanceState);
            addPreferencesFromResource(R.xml.preferences);

        }
    }
}

这是布局文件 -

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <android.support.v7.widget.Toolbar
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent"
        android:elevation="20dp"
        android:id="@+id/settings_toolbar"
        android:theme="@style/AppTheme.Base"
        android:layout_height="wrap_content"
        android:background="?attr/colorPrimary"
        android:minHeight="?attr/actionBarSize" />

    <FrameLayout
        android:id="@+id/content_frame"
        android:layout_below="@+id/settings_toolbar"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</RelativeLayout>

尝试使用

protected void onCreate(Bundle savedInstanceState)

代替

public void onCreate(Bundle savedInstanceState, PersistableBundle persistentState)
