我正在尝试创建一个带有滑动选项卡的圆形浮动操作菜单按钮。主浮动操作按钮正在工作，但子菜单按钮的点击事件不起作用。

这是菜单按钮的xml文件：

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
>

<android.support.design.widget.FloatingActionButton
    android:id="@+id/fab_1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="bottom|end"
    android:layout_margin="@dimen/fab_margin"
    android:src="@android:drawable/ic_menu_compass"
    android:visibility="invisible"
    app:backgroundTint="@color/colorAccent"
    app:fabSize="mini" />

<android.support.design.widget.FloatingActionButton
    android:id="@+id/fab_2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="bottom|end"
    android:layout_margin="@dimen/fab_margin"
    android:src="@android:drawable/ic_menu_myplaces"
    android:visibility="invisible"
    app:backgroundTint="@color/colorAccent"
    app:fabSize="mini" />

<android.support.design.widget.FloatingActionButton
    android:id="@+id/fab_3"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="bottom|end"
    android:layout_margin="@dimen/fab_margin"
    android:src="@android:drawable/ic_menu_share"
    android:visibility="invisible"
    app:backgroundTint="@color/colorAccent"
    app:fabSize="mini" />
</FrameLayout>

Activity_main.xml：

这是 MainActivity.java 类：

public class MainActivity extends AppCompatActivity  {

private Toolbar toolbar;
NavigationDrawer navigationDrawer;
DrawerLayout drawerLayout;

FloatingActionButton fab;
FloatingActionButton fab1;
FloatingActionButton fab2;
FloatingActionButton fab3;
CoordinatorLayout coordinatorLayout;

private boolean FAB_status=false;

Animation show_fab_1;
Animation hide_fab_1;
Animation show_fab_2;
Animation hide_fab_2;
Animation show_fab_3;
Animation hide_fab_3;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    ViewPager viewPager = (ViewPager) findViewById(R.id.viewPager);
    TabLayout tabLayout = (TabLayout) findViewById(R.id.sliding_tab);
    toolbar = (Toolbar) findViewById(R.id.app_bar);
    drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);

    setSupportActionBar(toolbar);
    getSupportActionBar().setDisplayShowHomeEnabled(true);
    viewPager.setAdapter(new ViewPagerAdapter(getSupportFragmentManager(), MainActivity.this));
    tabLayout.setupWithViewPager(viewPager);

    navigationDrawer = (NavigationDrawer) getSupportFragmentManager().findFragmentById(R.id.nav_drawer);
    navigationDrawer.setUp(R.id.nav_drawer, drawerLayout, toolbar);

    coordinatorLayout= (CoordinatorLayout) findViewById(R.id.coordinatorLayout);
    fab= (FloatingActionButton) findViewById(R.id.fab);
    fab1= (FloatingActionButton) findViewById(R.id.fab_1);
    fab2= (FloatingActionButton) findViewById(R.id.fab_2);
    fab3= (FloatingActionButton) findViewById(R.id.fab_3);

    show_fab_1= AnimationUtils.loadAnimation(getApplication(),R.anim.fab1_show);
    hide_fab_1= AnimationUtils.loadAnimation(getApplication(),R.anim.fab1_hide);
    show_fab_2= AnimationUtils.loadAnimation(getApplication(),R.anim.fab2_show);
    hide_fab_2= AnimationUtils.loadAnimation(getApplication(),R.anim.fab2_hide);
    show_fab_3= AnimationUtils.loadAnimation(getApplication(),R.anim.fab3_show);
    hide_fab_3= AnimationUtils.loadAnimation(getApplication(),R.anim.fab3_hide);


    fab.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            if (FAB_status == false) {
                //Display FAB menu
                expandFab();
                FAB_status = true;
            } else {
                //Close FAB menu
                hideFAB();
                FAB_status = false;
            }
        }
    });

    fab1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Toast.makeText(getApplication(), "Floating Action Button 1", Toast.LENGTH_SHORT).show();
        }
    });

    fab2.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Toast.makeText(getApplication(), "Floating Action Button 2", Toast.LENGTH_SHORT).show();
        }
    });

    fab3.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Toast.makeText(getApplication(), "Floating Action Button 3", Toast.LENGTH_SHORT).show();
        }
    });

}

添加到 XML 布局：

<android.support.design.widget.FloatingActionButton
        android:id="@+id/myFAB"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/your_icon"
        app:elevation="4dp"
        ... />

添加到后面的代码：

FloatingActionButton myFab = (FloatingActionButton) myView.findViewById(R.id.myFAB); 
myFab.setOnClickListener(new View.OnClickListener() { 
    public void onClick(View v) { 
          // TODO something when floating action menu third item clicked
    } 
});
