package viralandroid.com.androidmaterialdesigntutorial;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;import com.github.clans.fab.FloatingActionButton;
import com.github.clans.fab.FloatingActionMenu;public class MaterialDesignFloatingActionMenu extends AppCompatActivity {
FloatingActionMenu materialDesignFAM;
FloatingActionButton floatingActionButton1, floatingActionButton2, floatingActionButton3;@Override

super.onCreate(savedInstanceState);
setContentView(R.layout.material_design_floating_action_menu);materialDesignFAM = findViewById(R.id.material_design_android_floating_action_menu);

});
floatingActionButton3.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {

});
}
}
运行错误:
com.github.clans.fab.FloatingActionButton cannot be cast to android.support.design.widget.FloatingAction
导入包应该是：
import com.github.clans.fab.FloatingActionMenu;
import com.github.clans.fab.FloatingActionButton;
不应该有：
import android.support.design.widget.FloatingAction
