Answer 1

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" /> 

它包含三個項目，如下所示。它在res/menu目錄內創建。 File：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> 

它顯示按鈕單擊上的彈出菜單。 File：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 
}
