RapidFloatingActionButton
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
使用方式:
依赖:
AndroidBucket(https://github.com/wangjiegulu/AndroidBucket):基础工具包
AndroidInject(https://github.com/wangjiegulu/androidInject):注解框架
NineOldAndroids(https://github.com/JakeWharton/NineOldAndroids):兼容低版本的动画框架
activity_main.xml:
1 <com.wangjie.rapidfloatingactionbutton.RapidFloatingActionLayout
2 xmlns:rfal="http://schemas.android.com/apk/res-auto"
3 android:id="@+id/activity_main_rfal"
4 android:layout_width="match_parent"
5 android:layout_height="match_parent"
6 rfal:rfal_frame_color="#ffffff"
7 rfal:rfal_frame_alpha="0.7"

12 android:layout_width="wrap_content"
13 android:layout_height="wrap_content"
14 android:layout_alignParentRight="true"
15 android:layout_alignParentBottom="true"
16 android:layout_marginRight="15dp"
17 android:layout_marginBottom="15dp"
18 android:padding="8dp"
19 rfab:rfab_size="normal"
20 rfab:rfab_drawable="@drawable/rfab__drawable_rfab_default"
21 rfab:rfab_color_normal="#37474f"
22 rfab:rfab_color_pressed="#263238"
23 rfab:rfab_shadow_radius="7dp"
24 rfab:rfab_shadow_color="#999999"
25 rfab:rfab_shadow_dx="0dp"
26 rfab:rfab_shadow_dy="5dp"
27 />
28 </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>
属性解释
RapidFloatingActionLayout:
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
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:
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、label的背景图片、字体大小颜色甚至动画。
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
