Android上下文菜單

Question

我想創建一個上下文菜單。我試過以下內容

public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 

} 

public void onCreateContextMenu(ContextMenu menu, View v, 
     ContextMenuInfo menuInfo) { 
    super.onCreateContextMenu(menu, v, menuInfo); 
    MenuInflater inflater = getMenuInflater(); 
    inflater.inflate(R.layout.menuex, menu); 
} 

爲什麼我的上下文菜單不顯示？

您必須致電registerForContextMenu(View)才能爲特定項目註冊上下文菜單。
