关于PreferenceActivity、PreferenceFragment、ToolBar就不再做介绍了，本文主要讲解的是在PreferenceActivity、PreferenceFragment中添加ToolBar。

下面介绍不同版本相应的方法:

PreferenceActivity+ToolBar(限Android 5.0以上)

继承PreferenceActivity重写onCreate方法添加如下代码:

  @Override
  protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setStatusBar();
      //找到Activity根布局
      ViewGroup rootView = (ViewGroup) findViewById(android.R.id.content);
      //获取根布局子View
      View content = rootView.getChildAt(0);
      //加载自定义布局文件
      LinearLayout toolbarLayout = (LinearLayout)LayoutInflater.from(this).inflate(R.layout.activity_toolbar, null);
       //移除根布局所有子view
      rootView.removeAllViews();
      //注意这里一要将前面移除的子View添加到我们自定义布局文件中，否则PreferenceActivity中的Header将不会显示
      toolbarLayout.addView(content);
      //将包含Toolbar的自定义布局添加到根布局中
      rootView.addView(toolbarLayout);
      //设置toolbar
      Toolbar toolbar=(Toolbar)toolbarLayout.findViewById(R.id.toolbar);
      toolbar.setTitle("设置");
      toolbar.setTitleTextColor(Color.WHITE);
      Drawable d=getResources().getDrawable(R.drawable.abc_ic_ab_back_mtrl_am_alpha);
      toolbar.setNavigationIcon(d);
}

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

    <android.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="?attr/colorPrimary"
        android:minHeight="?attr/actionBarSize">
    </android.widget.Toolbar>

@Override

     super.onCreate(savedInstanceState);
     //直接调用setContentView方法
     setContentView(R.layout.activity_toolbar);
     Toolbar toolbar=(Toolbar)findViewById(R.id.toolbar);
     toolbar.setTitle("设置");
     toolbar.setTitleTextColor(Color.WHITE);
     Drawable d=getResources().getDrawable(R.drawable.abc_ic_ab_back_mtrl_am_alpha);
     toolbar.setNavigationIcon(d);
}

       <--!这里必须能添加一个id为@android:id/list的ListView否则会报错-->
