如何在android中实现下面提到的显示？

我的问题是，我希望实现一个显示，在点击每首歌曲侧面的虚线按钮时，我希望弹出一个显示，就像下面显示的第二张图像一样？

To create POPUp menu on button click:

list_item.xml：

<Button  
    android:id="@+id/button1"  
    android:layout_width="wrap_content"  
    android:layout_height="wrap_content"  
    android:layout_alignParentLeft="true"  
    android:layout_alignParentTop="true"  
    android:layout_marginLeft="62dp"  
    android:layout_marginTop="50dp"  
    android:text="Show Popup" />

它包含三个项目，如下所示。它在res / menu目录中创建。文件：poupup_menu.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android" >  

<item  
    android:id="@+id/one"  
    android:title="PlayNext"/>  

<item  
    android:id="@+id/two"  
    android:title="AddtoPlayList"/>  

<item  
    android:id="@+id/three"  
    android:title="Add to Queue"/>  
</menu>  

按钮单击时显示弹出菜单。文件：MainActivity.java

private Button button1;  

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

    button1 = (Button) findViewById(R.id.button1);
    button1.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            //Creating the instance of PopupMenu
            PopupMenu popup = new PopupMenu(MainActivity.this, button1);
            //Inflating the Popup using xml file
            popup.getMenuInflater()
                .inflate(R.menu.popup_menu, popup.getMenu());

            //registering popup with OnMenuItemClickListener
            popup.setOnMenuItemClickListener(new      

           PopupMenu.OnMenuItemClickListener() {
                public boolean onMenuItemClick(MenuItem item) {
                    Toast.makeText(
                        MainActivity.this,
                        "You Clicked : " + item.getTitle(),
                        Toast.LENGTH_SHORT
                    ).show();
                    return true;
                }
            });

            popup.show(); //showing popup menu
        }
    }); //closing the setOnClickListener method
}
