我的问题围绕 浮动操作按钮 这是在Android的材料设计介绍。
My question revolves around the Floating action button that was introduced in Android Material Design.
有许多图书馆在GitHub上提供了该组件为：
There are many library offering this component on GitHub as:
Android的浮点操作按钮 FloatingActionButton CircularFloatingActionMenu 晶圆厂 浮动动作按钮 Android-floating-action-button FloatingActionButton CircularFloatingActionMenu Fab Floating-action-button不过，我的问题是：
是否与 android.support.vX 的最后一个发行版是专为浮动操作按钮？
Is there a native component with the last release of android.support.vX that was built for Floating action button?
如组件：
android.support.v7.cardview android.support.v4.widget.DrawerLayout android.support.v7.widget.RecyclerView ...推荐答案
今天（29/05/2015），它是正式缴费与新材料设计支持库。
Today (29/05/2015) it is officially avaiable with the new Material Design support Library.
就在这个依赖添加到您的 build.gradle
Just add this dependency to your build.gradle
compile 'com.android.support:design:22.2.0'
添加此视图布局：
<android.support.design.widget.FloatingActionButton
android:id="@+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="end|bottom"
android:src="@drawable/ic_done" />
和使用它：
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
//TODO
}
});
