FloatingActionButton 子菜单

【问题描述】：

我想实现类似 pushbullet 的 FAB 子菜单。但我不知道如何在片段和活动中点击 FAB。

这是 pushbullet FAB 的样子：

现在我正在做的是将 FAB 菜单布局视为一个片段。当我点击工厂时，只需启动片段。但是，FAB 菜单片段膨胀后，我无法单击 FAB。因为 FAB 菜单片段会覆盖 FAB 按钮。

有人知道pushbullet 是如何制作FAB 菜单的吗？？？

嗨@Harry，我现在已经成功了。但是你知道如何确保背景一直是暗半透明的吗？我的只有到 ActionBar 下方

使用工具栏而不是操作栏。如果您喜欢，请投票给答案！

【参考方案1】：

首先将此添加到您的依赖项 compile 'com.getbase:floatingactionbutton:1.10.1'

dependencies 
    compile fileTree(include: ['*.jar'], dir: 'libs')
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', 
        exclude group: 'com.android.support', module: 'support-annotations'
    )
    compile 'com.android.support:appcompat-v7:25.3.1'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:design:25.3.1'

    compile 'com.getbase:floatingactionbutton:1.10.1'

然后将以下代码粘贴到您的片段：

public class YourFragment extends BaseFragment  

    @Override
    public void onAttach(Context context) 
        super.onAttach(context);
    

    @Override
    public void onCreate(@Nullable Bundle savedInstanceState) 
        super.onCreate(savedInstanceState);
    

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) 

        View v = inflater.inflate(R.layout.fragment_home, null, false);
        getActivity().setTitle(getResources().getString(R.string.app_name));

        v.findViewById(R.id.pink_icon).setOnClickListener(new View.OnClickListener() 
            @Override
            public void onClick(View v) 
            
        );

        FloatingActionButton button = (FloatingActionButton) v.findViewById(R.id.setter);
        button.setSize(FloatingActionButton.SIZE_MINI);
        button.setColorNormalResId(R.color.pink);
        button.setColorPressedResId(R.color.pink_pressed);
        button.setIcon(R.drawable.bubble_in);
        button.setStrokeVisible(false);

        final View actionB = v.findViewById(R.id.action_b);

        FloatingActionButton actionC = new FloatingActionButton(baseActivity);
        actionC.setTitle("Hide/Show Action above");
        actionC.setOnClickListener(new View.OnClickListener() 
            @Override
            public void onClick(View v) 
                actionB.setVisibility(actionB.getVisibility() == View.GONE ? View.VISIBLE : View.GONE);
            
        );

        final FloatingActionsMenu menuMultipleActions = (FloatingActionsMenu) v.findViewById(R.id.multiple_actions);
        menuMultipleActions.addButton(actionC);

        final FloatingActionButton removeAction = (FloatingActionButton) v.findViewById(R.id.button_remove);
        removeAction.setOnClickListener(new View.OnClickListener() 
            @Override
            public void onClick(View v) 
                ((FloatingActionsMenu) v.findViewById(R.id.multiple_actions_down)).removeButton(removeAction);
            
        );

        ShapeDrawable drawable = new ShapeDrawable(new OvalShape());
        drawable.getPaint().setColor(getResources().getColor(R.color.white));
        ((FloatingActionButton) v.findViewById(R.id.setter_drawable)).setIconDrawable(drawable);

        final FloatingActionButton actionA = (FloatingActionButton) v.findViewById(R.id.action_a);
        actionA.setOnClickListener(new View.OnClickListener() 
            @Override
            public void onClick(View view) 
                actionA.setTitle("Action A clicked");
            
        );

        // Test that FAMs containing FABs with visibility GONE do not cause crashes
        v.findViewById(R.id.button_gone).setVisibility(View.GONE);

        final FloatingActionButton actionEnable = (FloatingActionButton) v.findViewById(R.id.action_enable);
        actionEnable.setOnClickListener(new View.OnClickListener() 
            @Override
            public void onClick(View view) 
                menuMultipleActions.setEnabled(!menuMultipleActions.isEnabled());
            
        );

        FloatingActionsMenu rightLabels = (FloatingActionsMenu) v.findViewById(R.id.right_labels);
        FloatingActionButton addedOnce = new FloatingActionButton(baseActivity);
        addedOnce.setTitle("Added once");
        rightLabels.addButton(addedOnce);

        FloatingActionButton addedTwice = new FloatingActionButton(baseActivity);
        addedTwice.setTitle("Added twice");
        rightLabels.addButton(addedTwice);
        rightLabels.removeButton(addedTwice);
        rightLabels.addButton(addedTwice);


        return v;

    

    @Override
    public void onViewCreated(View view, Bundle savedInstanceState) 
        super.onViewCreated(view, savedInstanceState);
    

BaseFragment 应该是：

public class BaseFragment extends Fragment implements View.OnClickListener  
    protected BaseActivity baseActivity;

    @Override
    public void onAttach(Context context) 
        super.onAttach(context);
        baseActivity = (BaseActivity) context;
baseActivity.getApplication();

    

    @Override
    public void onDetach() 
        baseActivity = null;

        super.onDetach();
