Floating Action Button cast issue

Question

I am getting this error:

Caused by: java.lang.ClassCastException: com.github.clans.fab.FloatingActionButton cannot be cast to android.support.design.widget.FloatingActionButton.

Here is my Code:

Vechile.xml

   <RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

        fab:menu_labels_textSize="15sp"
        fab:menu_openDirection="up"
        fab:menu_shadowColor="#66aff198"
        fab:menu_shadowRadius="4dp"
        fab:menu_shadowXOffset="1dp"
        fab:menu_shadowYOffset="4dp"
        fab:menu_showShadow="true">

        <com.github.clans.fab.FloatingActionButton
            android:id="@+id/material_design_floating_action_menu_item1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/car"
            fab:fab_label="Add Car"
            fab:fab_size="mini"
            fab:menu_colorNormal="#3F51B5"/>
       </com.github.clans.fab.FloatingActionMenu>
   </RelativeLayout>

Vechile.java

FloatingActionMenu materialDesignFAM;
FloatingActionButton floatingActionButton1;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.vehicle);
    materialDesignFAM = (FloatingActionMenu) 
    findViewById(R.id.material_design_android_floating_action_menu);
    floatingActionButton1 = (FloatingActionButton) 
    findViewById(R.id.material_design_floating_action_menu_item1);

    floatingActionButton1.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {


           Intent intent = new Intent(VehicleActivity.this, Brand 
 Activity.class);

            startActivity(intent);
        }
    });

}
}

In my case, I clear the cache, and the issue is resolved. – Md Imran Choudhury Jul 17 '20 at 05:56 — Md Imran Choudhury, Jul 17 '20 at 05:56

Your activity is importing from the support library and the import is android.support.design.widget.FloatingActionButton while you are using an external library element in your xml com.github.clans.fab.FloatingActionButton. Use correct imports and you won't face ClassCastException

Make sure your activity has

import com.github.clans.fab.FloatingActionButton

and not

import android.support.design.widget.FloatingActionButton

Similar thing for FloatingActionMenu. Make sure your import starts with the package name of the library you are using. Normally people face this time of error because of auto importing by Android Studio

You can simply use android's FAB itself like this:

<android.support.design.widget.FloatingActionButton
    android:id="@+id/fab"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="bottom|end"
    android:layout_marginRight="16dp"
    android:layout_marginBottom="20dp"
    app:backgroundTint="@color/pink"
    android:src="@mipmap/add_icon"/>

You can customize the FAB however you like in the above widget itself. And call it like this:

FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);

Makes life easier!

See that if u added a Button Instead of FloatingActionButton when calling a button object. just simply put FloatingActionButton /your button object name/.
