带有 RecyclerView 的 Activity 中的浮动操作按钮未收到 onClick

Question

浮动操作按钮上的点击操作不起作用。

我正在学习 android RecyclerView，我能够用数据填充活动。我在活动的底部也有 FloatingActionButton，它不响应触摸事件。即使监听器附加到按钮，当我点击它时什么也没有发生。

EventsActivity.kt

class EventsActivity : AppCompatActivity() {
    ...

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_events)
        setSupportActionBar(toolbar)

        //MY FAB BUTTON IS ATTACHED WITH LISTENER HERE
        addEvent.setOnClickListener { view ->
            Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
                .setAction("Action", null).show()
        }

        ...

        setupRecyclerAdapter()
    }
}

activity_events.xml

<?xml version="1.0" encoding="utf-8"?>

                android:layout_width="match_parent"
                android:theme="@style/AppTheme.AppBarOverlay">

            <androidx.appcompat.widget.Toolbar
                    android:id="@+id/toolbar"
                    android:layout_width="match_parent"
                    android:layout_height="?attr/actionBarSize"
                    android:background="?attr/colorPrimary"
                    app:popupTheme="@style/AppTheme.PopupOverlay"/>

        </com.google.android.material.appbar.AppBarLayout>

        <include android:id="@+id/content_events"
                 layout="@layout/content_events"/>

        <com.google.android.material.floatingactionbutton.FloatingActionButton
                android:id="@+id/addEvent"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="end|bottom"
                android:layout_margin="@dimen/fab_margin"
                app:srcCompat="@android:drawable/ic_input_add"/>

    </androidx.coordinatorlayout.widget.CoordinatorLayout>
</layout>

Answer 1

addEvent.setOnClickListener(this)

override fun onClick(v: View?)
{
   when(v!!.id)
    {
        R.id. addEvent ->
    {
       Log.i("FABCLICK","Click on Fab icon")
    }

    }
}

Answer 2

您可以尝试打印日志或 Toast 来代替 Snackbar 吗？

之前

  addEvent.setOnClickListener { view ->
        Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
            .setAction("Action", null).show()
    }

之后

  addEvent.setOnClickListener { view ->
       val toast = Toast.makeText(applicationContext, "Hello Javatpoint", Toast.LENGTH_LONG)  
        toast.show()  
    }
