如何使用Android SDK API 21版(支持库)删除新工具栏中的额外填充？

我在谈论这张照片上的红色箭头:

这是我正在使用的代码:

<android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_height="wrap_content"
        android:layout_width="match_parent"
        android:background="?attr/colorPrimary"
        android:padding="0dp"
        android:layout_margin="0dp">

        <RelativeLayout
            android:id="@+id/action_bar_layout"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_margin="0dp"
            android:padding="0dp"
            android:background="#000000">

            <Spinner
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"/>

        </RelativeLayout>
</Toolbar>

正如您所看到的,我已将所有相关填充设置为0,但Spinner周围仍有填充.我做错了什么或者我需要做些什么才能摆脱额外的填充？

编辑 有些人质疑我为什么要这样做.

根据材料设计规格,旋转器应距离左侧72dp

我需要中和Google为了正确放置我的微调器而放置的填充:

根据Chris Bane在下面的回答,我将contentInsetStart设置为0.对于支持库,您需要使用app命名空间:

<android.support.v4.widget.DrawerLayout
    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.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_height="wrap_content"
        android:layout_width="match_parent"
        android:minHeight="@dimen/action_bar_height"
        android:background="?attr/colorPrimary"
        android:contentInsetStart="0dp"
        android:contentInsetLeft="0dp"
        app:contentInsetLeft="0dp"
        app:contentInsetStart="0dp"
        app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
        app:popupTheme="@style/ThemeOverlay.AppCompat.Light">

</android.support.v4.widget.DrawerLayout>

我希望这对某人有所帮助,让我困惑了好几天.

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

<ListView
    android:id="@+id/left_drawer"
    android:layout_width="240dp"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    android:background="#111"
    android:choiceMode="singleChoice"
    android:divider="@android:color/transparent"
    android:dividerHeight="0dp" />

根据创建导航抽屉文档将其添加到布局xml中

我正在尝试实现导航抽屉,但我不断收到此错误.我看到了类似的问题,但对我没有用.我有以下布局activity_main2.xml:

<android.support.v4.widget.DrawerLayout
    android:layout_width="match_parent"
    android:id="@+id/drawerLayout"
    android:layout_height="match_parent">

   <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"/>

   <RelativeLayout
        android:layout_gravity="left|start"
        android:layout_width="match_parent"
        android:background="#fff"
        android:layout_height="match_parent">

        <ListView
            android:id="@+id/left_drawer"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:divider="#eee"
            android:background="#fff"
            android:dividerHeight="1dp" />
    </RelativeLayout>
</android.support.v4.widget.DrawerLayout>

在我的activity_main2.java上

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main2);
    initView();
    if (toolbar != null) {
        //toolbar.setTitle("");
        setSupportActionBar(toolbar);
    }
    initDrawer();
}

private void initView() {
    leftDrawerList = (ListView) findViewById(R.id.left_drawer);
    toolbar = (Toolbar) findViewById(R.id.toolbar);
    drawerLayout = (DrawerLayout) findViewById(R.id.drawerLayout);
    navigationDrawerAdapter = new ArrayAdapter<String>( MainActivity.this, android.R.layout.simple_list_item_1, leftSliderData);
    leftDrawerList.setAdapter(navigationDrawerAdapter);
    leftDrawerList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long …

我正在关注本教程,面对一个奇怪的问题.

不要紧,什么是我的DrawerLayout,但如果它layout_height还是layout_width被设置为硬编码的一些其他的东西,它会抛出此运行时异常.

我试图在图形布局工具中渲染输出时看到很多关于此错误的报告,但在运行时错误中找不到任何报告.

我有最新的支持库,刚刚更新到版本 21.0.2

如果可能的话,我想避免硬编码我的身高和宽度.

文件的开头看起来像这样.这样,它就会粉碎.

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >
