Google推出了MaterialDesign的设计语言,其中FloatingActionButton就是一部分,但是Google却没有提供一个官方的FloatingActionButton控件,网上找了几个试用了下,但是始终没有找到合适的,所以,自己动手丰衣足食了。
RapidFloatingActionButton(以下简称RFAB)是Floating Action Button的快速实现。
Github地址:https://github.com/wangjiegulu/RapidFloatingActionButton
依赖:
AndroidBucket(https://github.com/wangjiegulu/AndroidBucket):基础工具包
AndroidInject(https://github.com/wangjiegulu/androidInject):注解框架

在需要增加RFAB最外层使用<com.wangjie.rapidfloatingactionbutton.RapidFloatingActionLayout>
,按钮使用<com.wangjie.rapidfloatingactionbutton.RapidFloatingActionButton>
rfal_frame_color: 展开RFAB时候最外覆盖层的颜色,默认是纯白色
rfal_frame_alpha: 展开RFAB时候最外覆盖层的透明度(0 ~ 1),默认是0.7
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
1 @AILayout(R.layout.activity_main) 2 public class MainActivity extends AIActionBarActivity implements RapidFloatingActionContentLabelList.OnRapidFloatingActionContentListener { 3 4 @AIView(R.id.activity_main_rfal) 5 private RapidFloatingActionLayout rfaLayout; 6 @AIView(R.id.activity_main_rfab) 7 private RapidFloatingActionButton rfaBtn; 8 private RapidFloatingActionButtonHelper rfabHelper; 9 10 @Override 11 protected void onCreate(Bundle savedInstanceState) { 12 super.onCreate(savedInstanceState); 13 14 RapidFloatingActionContentLabelList rfaContent = new RapidFloatingActionContentLabelList(context); 15 rfaContent.setOnRapidFloatingActionContentListener(this); 16 List<RFACLabelItem> items = new ArrayList<>(); 17 items.add(new RFACLabelItem<Integer>() 18 .setLabel("Github: wangjiegulu") 19 .setResId(R.drawable.ic_launcher) 20 .setIconNormalColor(0xffd84315) 21 .setIconPressedColor(0xffbf360c) 22 .setWrapper(0) 23 ); 24 items.add(new RFACLabelItem<Integer>() 25 .setLabel("tiantian.china.2@gmail.com") 26 .setResId(R.drawable.ic_launcher) 27 .setIconNormalColor(0xff4e342e) 28 .setIconPressedColor(0xff3e2723) 29 .setWrapper(1) 30 ); 31 items.add(new RFACLabelItem<Integer>() 32 .setLabel("WangJie") 33 .setResId(R.drawable.ic_launcher) 34 .setIconNormalColor(0xff056f00) 35 .setIconPressedColor(0xff0d5302) 36 .setWrapper(2) 37 ); 38 items.add(new RFACLabelItem<Integer>() 39 .setLabel("Compose") 40 .setResId(R.drawable.ic_launcher) 41 .setIconNormalColor(0xff283593) 42 .setIconPressedColor(0xff1a237e) 43 .setWrapper(3) 44 ); 45 rfaContent 46 .setItems(items) 47 .setIconShadowRadius(ABTextUtil.dip2px(context, 5)) 48 .setIconShadowColor(0xff999999) 49 .setIconShadowDy(ABTextUtil.dip2px(context, 5)) 50 ; 51 52 rfabHelper = new RapidFloatingActionButtonHelper( 53 context, 54 rfaLayout, 55 rfaBtn, 56 rfaContent 57 ).build(); 58 59 } 60 61 @Override 62 public void onRFACItemLabelClick(int position, RFACLabelItem item) { 63 Toast.makeText(getContext(), "clicked label: " + position, Toast.LENGTH_SHORT).show(); 64 rfabHelper.toggleContent(); 65 } 66 67 @Override 68 public void onRFACItemIconClick(int position, RFACLabelItem item) { 69 Toast.makeText(getContext(), "clicked icon: " + position, Toast.LENGTH_SHORT).show(); 70 rfabHelper.toggleContent(); 71 } 72 }
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。
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
