import android.os.Bundle;
import android.view.View;

import com.google.android.material.snackbar.Snackbar;

    private Button button;
    @Override

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        button=findViewById(R.id.a_btn);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                //"aaaa"即为Snackbar左侧显示内容，setAction可以设计点击事件
                Snackbar.make(v,"aaaa",Snackbar.LENGTH_LONG)
                        .setAction("tob", new View.OnClickListener() {
                            @Override
                            public void onClick(View v) {

                            }
                        }).show();
            }
        });
    }
}

在CoordinatorLayout中允许滑动取消Snackbar
