环境：

主机:WIN10

开发环境:Android Studio 2.2 Preview 3

说明：

用第三方库CircularFloatingActionMenu实现悬浮按钮扇形展开

效果图：

源码：

private void initFloatingActionsMenu(View view) {        // 添加 右下角的白色+号按钮        final ImageView fabIcon = new ImageView(getContext());        fabIcon.setImageDrawable(getResources().getDrawable(R.drawable.ic_fab, null));        final FloatingActionButton fabButton = new FloatingActionButton.Builder(getActivity())                .setContentView(fabIcon)                .setPosition(FloatingActionButton.POSITION_BOTTOM_LEFT)                .build();        SubActionButton.Builder rLSubBuilder = new SubActionButton.Builder(getActivity());        ImageView imageViewQuit = new ImageView(getContext());        ImageView imageViewTool = new ImageView(getContext());        ImageView imageViewPalette = new ImageView(getContext());        ImageView imageViewCamera = new ImageView(getContext());        imageViewQuit.setImageDrawable(getResources().getDrawable(R.drawable.ic_call_end_black_48dp, null));        imageViewTool.setImageDrawable(getResources().getDrawable(R.drawable.ic_settings_applications_black_48dp, null));        imageViewPalette.setImageDrawable(getResources().getDrawable(R.drawable.ic_color_lens_black_48dp, null));        imageViewCamera.setImageDrawable(getResources().getDrawable(R.drawable.ic_camera_alt_black_48dp, null));        SubActionButton buttonQuit = rLSubBuilder.setContentView(imageViewQuit).build();        SubActionButton buttonPalette = rLSubBuilder.setContentView(imageViewPalette).build();        SubActionButton buttonTool = rLSubBuilder.setContentView(imageViewTool).build();        SubActionButton buttonCamera = rLSubBuilder.setContentView(imageViewCamera).build();        // Build the menu with default options: light theme, 90 degrees, 72dp        // radius.        // Set 4 default SubActionButtons        // FloatingActionMenu通过attachTo(fabButton)附着到FloatingActionButton        final FloatingActionMenu buttonToolMenu = new FloatingActionMenu.Builder(getActivity())                .addSubActionView(buttonPalette)                .addSubActionView(buttonCamera)                .addSubActionView(buttonTool)                .addSubActionView(buttonQuit)                .setStartAngle(0)                .setEndAngle(-90)                .attachTo(fabButton)                .build();        // Listen menu open and close events to animate the button content view        buttonToolMenu.setStateChangeListener(new FloatingActionMenu.MenuStateChangeListener() {            @Override            public void onMenuOpened(FloatingActionMenu menu) {                // 增加按钮中的+号图标顺时针旋转45度                // Rotate the icon of fabButton 45 degrees clockwise                fabIcon.setRotation(0);                PropertyValuesHolder pvhR = PropertyValuesHolder.ofFloat(View.ROTATION, 45);                ObjectAnimator animation = ObjectAnimator.ofPropertyValuesHolder(fabIcon, pvhR);                animation.start();            }            @Override            public void onMenuClosed(FloatingActionMenu menu) {                // 增加按钮中的+号图标逆时针旋转45度                // Rotate the icon of fabButton 45 degrees                // counter-clockwise                fabIcon.setRotation(45);                PropertyValuesHolder pvhR = PropertyValuesHolder.ofFloat(View.ROTATION, 0);                ObjectAnimator animation = ObjectAnimator.ofPropertyValuesHolder(fabIcon, pvhR);                animation.start();            }        });        RxView.clicks(buttonQuit)                .throttleFirst(1, TimeUnit.SECONDS)                .compose(this.bindUntilEvent(FragmentEvent.DESTROY))                .subscribe(v -> {                    Voip.getInstance().hangUpCall(callId);                    finishActivity();                });        RxView.clicks(buttonPalette)                .throttleFirst(1, TimeUnit.SECONDS)                .compose(this.bindUntilEvent(FragmentEvent.DESTROY))                .subscribe(v -> {                    buttonToolMenu.close(true);//                    buttonToolMenu.collapse();                    dialogPalette.show();                });        RxView.clicks(buttonCamera)                .throttleFirst(1, TimeUnit.SECONDS)                .compose(this.bindUntilEvent(FragmentEvent.DESTROY))                .subscribe(v -> {                    buttonToolMenu.close(true);//                    buttonToolMenu.collapse();                    dialogSelectImage.show();                });    }
