FWIW, 

It would appear that there is no <code>Snackbar</code> implementation in the <a href="http://developer.android.com/preview/reference.html" rel="nofollow">L Developer Preview</a>. I've also implemented a <a href="https://github.com/MrEngineer13/SnackBar" rel="nofollow">Snackbar library</a> with the intentions of being as close to the <a href="http://www.google.com/design/spec/components/snackbars-and-toasts.html#" rel="nofollow">material design guidelines</a> as I can. Thanks.

Mabye take a look at this here.

I am guessing the native version will show up in the sdk eventually. It is a bit odd I agree.

blocks|key|4583273|text|Snackbar实际上只是一个有边际的Crouton。Crouton目前的形式只支持添加到ViewGroup的开始(第0项)，但是你可以在my+github上找到对Crouton，DownUnderMode的非常“斯特拉扬”增强。只需注意，官方的Crouton库和DownUnderMode版本有点不同步(当DownUnderMode拉取请求被接受时，有望在2058年修复)。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|4583274|entityMap|0|LINK|mutability|MUTABLE|url|https://github.com/keyboardsurfer/Crouton|1|https://github.com/coreform/Crouton^0|J|7|0|1X|9|1|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@$A|O|B|P|1|Q]|$A|R|B|S|1|T]]|C|$]]|$1|D|3|-4|5|6|7|U|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]|L|$5|G|H|I|C|$J|M]]]]

Snackbar is effectively just a <a href="https://github.com/keyboardsurfer/Crouton" rel="nofollow">Crouton</a> with some margins. Crouton in its current form only supports adding to start (0th item) of a ViewGroup, however you can find the very "strayan" enhancement to Crouton, DownUnderMode, at <a href="https://github.com/coreform/Crouton" rel="nofollow">my github</a>.
Just beware that the official Crouton library and DownUnderMode version are a little out of sync (which will hopefully be fixed in the year 2058 when the DownUnderMode pull request is accepted).

Here is simple way to implement snackbar in android 

Step 1. Add support library 23 and compile your project with 

<pre><code>compile 'com.android.support:appcompat-v7:23.0.1'
</code></pre>

Step 2. Add coordinate layout in your activity file

<pre><code>&lt;android.support.design.widget.CoordinatorLayout 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/coordinatorLayout"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 tools:context=".MainActivity"&gt;


&lt;/android.support.design.widget.CoordinatorLayout&gt;
</code></pre>

Step 3. Now add following code in your MainActivity.java to implement snackbar

<pre><code>public class MainActivity extends AppCompatActivity {

 CoordinatorLayout coordinatorLayout;

 @Override
 protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_main);
 coordinatorLayout = (CoordinatorLayout) findViewById(R.id.coordinatorLayout);
 ShowSnack();
 }

 public void ShowSnack() {
 Snackbar snackbar = Snackbar.make(coordinatorLayout, "Snackbar Label", Snackbar.LENGTH_LONG);
 snackbar.setAction("Action", new View.OnClickListener() {
 @Override
 public void onClick(View v) {
 Toast.makeText(MainActivity.this, "Action", Toast.LENGTH_LONG).show();
 }
 });
 snackbar.setActionTextColor(Color.RED);
 View snackbarView = snackbar.getView();
 snackbarView.setBackgroundColor(Color.DKGRAY);
 TextView textView = (TextView) snackbarView.findViewById(android.support.design.R.id.snackbar_text);
 textView.setTextColor(Color.YELLOW);
 snackbar.show();
 }
}
</code></pre>

Hope this will work for you.

The Material design website mentions a new Toast-like element called a Snackbar: <a href="http://www.google.com/design/spec/components/snackbars-and-toasts.html" rel="noreferrer">http://www.google.com/design/spec/components/snackbars-and-toasts.html</a>

The Android L preview SDK documentation (sorry can't link since it's only downloadable) doesn't have any mention of Snackbar in the classes list or as a modifier in the Toast class documentation. Am I missing something obvious or should I build my own Snackbar.java?

Is there code for Snackbars in Android L or are we expected to implement them ourselves?

Android

Material设计网站提到了一个新的类似吐司的元素，称为Snackbar：Android L预览版SDK文档(很抱歉无法链接，因为它只能下载)在类列表中没有提到Snackbar，也没有在Toast类文档中将Snackbar作为修饰符。我是否遗漏了一些显而易见的东西，或者我应该构建自己的Snackbar.java？

问Android L中有Snackbar的代码吗?或者我们希望自己实现它们？
