上下文菜单单击Android

Question

我不熟悉Android开发。我正试图添加一个上下文菜单到我的应用程序。我明白，默认情况下，它需要长时间点击按钮来打开上下文菜单。但我需要让它出现在单击上。我在这里尝试了所有其他的解决方案，但没有一个真正帮助我。

我已在下面发布我的代码。请让我知道要做些什么修改才能使其工作。

public class ThirdActivity extends ActionBarActivity { 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.third_layout); 
     confirmButton = (Button) findViewById(R.id.confirmButton); 
     registerForContextMenu(confirmButton); 
} 

public void onCreateContextMenu(ContextMenu menu, View v,ContextMenu.ContextMenuInfo menuInfo) { 
    super.onCreateContextMenu(menu, v, menuInfo); 
    menu.setHeaderTitle("Select Menu"); 
    menu.add(0, v.getId(), 0, "Action 1"); 
} 


public boolean onContextItemSelected(MenuItem item) { 

     if (item.getTitle() == "Action 1") { 
     //do something 
    } 
}

just : 

public class ThirdActivity extends ActionBarActivity { 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.third_layout); 
     confirmButton = (Button) findViewById(R.id.confirmButton); 
    confirmButton .setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      confirmButton .performLongClick(); 
     } 
    }); 
     registerForContextMenu(confirmButton); 
} 

public void onCreateContextMenu(ContextMenu menu, View v,ContextMenu.ContextMenuInfo menuInfo) { 
    super.onCreateContextMenu(menu, v, menuInfo); 
    menu.setHeaderTitle("Select Menu"); 
    menu.add(0, v.getId(), 0, "Action 1"); 
} 


public boolean onContextItemSelected(MenuItem item) { 

     if (item.getTitle() == "Action 1") { 
     //do something 
    } 
}
