RelativeLayout 填充影响我的工具栏

RelaiveLayout's paddings are effecting my ToolBar

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/background"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"

    >

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar_top"
        android:layout_height="wrap_content"
        android:layout_width="match_parent"
        android:minHeight="?attr/actionBarSize"
        android:background="@color/colorPrimary"
        android:fitsSystemWindows="true"
        >
        <TextView
            android:id="@+id/toolbar_title"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            style="@style/TextAppearance.AppCompat.Widget.ActionBar.Title"
            android:layout_gravity="center" />
    </android.support.v7.widget.Toolbar>
.
.
.
//etc
</RelativeLayout>

在我的 Activity,

Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar_top);
        TextView textView = (TextView) toolbar.findViewById(R.id.toolbar_title);
        textView.setText("My Title");
        setSupportActionBar(toolbar);
        getSupportActionBar().setDisplayShowTitleEnabled(false);

然后.., 工具栏显示如下..

我使用自定义工具栏的方式似乎很奇怪。我应该把我的工具栏放在哪里?我整晚都在尝试放置自定义工具栏。有什么建议吗?

试试这个

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

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar_top"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@color/colorPrimary"
        android:fitsSystemWindows="true"
        android:minHeight="?attr/actionBarSize">

        <TextView
            android:id="@+id/toolbar_title"
            style="@style/TextAppearance.AppCompat.Widget.ActionBar.Title"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center" />
    </android.support.v7.widget.Toolbar>

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:paddingBottom="@dimen/activity_vertical_margin"
        android:paddingLeft="@dimen/activity_horizontal_margin"
        android:paddingRight="@dimen/activity_horizontal_margin"
        android:paddingTop="@dimen/activity_vertical_margin">

    </RelativeLayout>

</LinearLayout>

不要把Toolbar放在相对布局里面,而是把相对布局放在toolbar下面,如下:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/thisLayoutisTheRootOne"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
   <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar_top"
        android:layout_height="wrap_content"
        android:layout_width="match_parent"
        android:minHeight="?attr/actionBarSize"
        android:background="@color/colorPrimary"
        android:fitsSystemWindows="true">
        <TextView
            android:id="@+id/toolbar_title"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            style="@style/TextAppearance.AppCompat.Widget.ActionBar.Title"
            android:layout_gravity="center" />
    </android.support.v7.widget.Toolbar>
    <RelativeLayout 
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_below="@+id/toolbar_top"
    android:background="@drawable/background"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin">
