RapidFloatingActionButton 是 Floating Action Button 的快速实现,RapidFloatingActionButton(以下简称RFAB)

使用方式:

依赖:
AndroidBucket:基础工具包
AndroidInject:注解框架

activity_main.xml:

<com.wangjie.rapidfloatingactionbutton.RapidFloatingActionLayout        xmlns:rfal="http://schemas.android.com/apk/res-auto"        android:id="@+id/activity_main_rfal"        android:layout_width="match_parent"        android:layout_height="match_parent"        rfal:rfal_frame_color="#ffffff"        rfal:rfal_frame_alpha="0.7"        >    <com.wangjie.rapidfloatingactionbutton.RapidFloatingActionButton            xmlns:rfab="http://schemas.android.com/apk/res-auto"            android:id="@+id/activity_main_rfab"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_alignParentRight="true"            android:layout_alignParentBottom="true"            android:layout_marginRight="15dp"            android:layout_marginBottom="15dp"            android:padding="8dp"            rfab:rfab_size="normal"            rfab:rfab_drawable="@drawable/rfab__drawable_rfab_default"            rfab:rfab_color_normal="#37474f"            rfab:rfab_color_pressed="#263238"            rfab:rfab_shadow_radius="7dp"            rfab:rfab_shadow_color="#999999"            rfab:rfab_shadow_dx="0dp"            rfab:rfab_shadow_dy="5dp"            />  </com.wangjie.rapidfloatingactionbutton.RapidFloatingActionLayout>

在需要增加RFAB最外层使用<com.wangjie.rapidfloatingactionbutton.RapidFloatingActionLayout>,按钮使用<com.wangjie.rapidfloatingactionbutton.RapidFloatingActionButton>

rfab_size: RFAB的尺寸大小,只支持两种尺寸(Material Design规范):            normal: 直径56dp            mini: 直径40dp    rfab_drawable: RFAB中间的图标,默认是一个"+"图标    rfab_color_normal: RFAB背景的普通状态下的颜色。默认是白色    rfab_color_pressed: RFAB背景的触摸按下状态的颜色。默认颜色是"#dddddd"    rfab_shadow_radius: RFAB的阴影半径。默认是0,表示没有阴影    rfab_shadow_color: RFAB的阴影颜色。默认是透明,另外如果rfab_shadow_radius为0,则该属性无效    rfab_shadow_dx: RFAB的阴影X轴偏移量。默认是0    rfab_shadow_dy: RFAB的阴影Y轴偏移量。默认是0

MainActivity:

@AILayout(R.layout.activity_main)  public class MainActivity extends AIActionBarActivity implements RapidFloatingActionContentLabelList.OnRapidFloatingActionContentListener {        @AIView(R.id.activity_main_rfal)      private RapidFloatingActionLayout rfaLayout;      @AIView(R.id.activity_main_rfab)      private RapidFloatingActionButton rfaBtn;      private RapidFloatingActionButtonHelper rfabHelper;        @Override      protected void onCreate(Bundle savedInstanceState) {          super.onCreate(savedInstanceState);            RapidFloatingActionContentLabelList rfaContent = new RapidFloatingActionContentLabelList(context);          rfaContent.setOnRapidFloatingActionContentListener(this);          List<RFACLabelItem> items = new ArrayList<>();          items.add(new RFACLabelItem<Integer>()                          .setLabel("Github: wangjiegulu")                          .setResId(R.drawable.ic_launcher)                          .setIconNormalColor(0xffd84315)                          .setIconPressedColor(0xffbf360c)                          .setWrapper(0)          );          items.add(new RFACLabelItem<Integer>()                          .setLabel("tiantian.china.2@gmail.com")                          .setResId(R.drawable.ic_launcher)                          .setIconNormalColor(0xff4e342e)                          .setIconPressedColor(0xff3e2723)                          .setWrapper(1)          );          items.add(new RFACLabelItem<Integer>()                          .setLabel("WangJie")                          .setResId(R.drawable.ic_launcher)                          .setIconNormalColor(0xff056f00)                          .setIconPressedColor(0xff0d5302)                          .setWrapper(2)          );          items.add(new RFACLabelItem<Integer>()                          .setLabel("Compose")                          .setResId(R.drawable.ic_launcher)                          .setIconNormalColor(0xff283593)                          .setIconPressedColor(0xff1a237e)                          .setWrapper(3)          );          rfaContent                  .setItems(items)                  .setIconShadowRadius(ABTextUtil.dip2px(context, 5))                  .setIconShadowColor(0xff999999)                  .setIconShadowDy(ABTextUtil.dip2px(context, 5))          ;            rfabHelper = new RapidFloatingActionButtonHelper(                  context,                  rfaLayout,                  rfaBtn,                  rfaContent          ).build();        }        @Override      public void onRFACItemLabelClick(int position, RFACLabelItem item) {          Toast.makeText(getContext(), "clicked label: " + position, Toast.LENGTH_SHORT).show();          rfabHelper.toggleContent();      }        @Override      public void onRFACItemIconClick(int position, RFACLabelItem item) {          Toast.makeText(getContext(), "clicked icon: " + position, Toast.LENGTH_SHORT).show();          rfabHelper.toggleContent();      }  }

除了xml中设置的RapidFloatingActionLayout和RapidFloatingActionButton之外,还需要RapidFloatingActionContent的实现类来填充和指定RFAB的内容和形式。
这里提供了一个快速的RapidFloatingActionContent的实现解决方案:RapidFloatingActionContentLabelList。你可以加入多个item(RFACLabelItem,当然,不建议加太多的item,导致超过一个屏幕),然后设置每个item的颜色、图标、阴影甚至动画。
它的效果可参考最上面的效果图片或者Google的Inbox的效果。
除此之外,你还需要使用RapidFloatingActionButtonHelper来把以上所有零散的组件组合起来。

关于扩展:

如果你不喜欢默认提供的RapidFloatingActionContentLabelList,理论上你可以扩展自己的内容样式。方法是继承com.wangjie.rapidfloatingactionbutton.RapidFloatingActionContent,然后初始化内容布局和样式,并调用父类的setRootView(xxx);方法即可。如果你需要增加动画,可以重写如下方法:

public void onExpandAnimator(AnimatorSet animatorSet);  public void onCollapseAnimator(AnimatorSet animatorSet);

把需要的Animator增加到animatorSet中即可
另外,作者也会不定期增加更多的RapidFloatingActionContent的扩展
