觸摸事件不能在單聲道中消耗

Question

我最近從Java移至C＃和Mono以進行Android開發。我有一個ListView，我想選擇返回true或false，但在單聲道中似乎沒有這樣做的選項。下面是一些代碼片段：

的Java（我試圖在單聲道再現）

ListView listview; 
ArrayAdapter<String> adapter; 

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

    listview = (ListView)findViewById(R.id.listView1); 
    adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1); 

    for (int i = 0; i < 50; i++) 
     adapter.add(Integer.toString(i)); 

    listview.setAdapter(adapter); 
    listview.setOnTouchListener(listenerOnTouch); 
} 

private OnTouchListener listenerOnTouch = new OnTouchListener() { 

    @Override 
    public boolean onTouch(View arg0, MotionEvent arg1) { 
     return false; // <---- This line doesn't exist in Mono 
    } 
}; 

單相當於：

ListView listview; 
    ArrayAdapter<String> adapter; 

    protected override void OnCreate (Bundle bundle) 
    { 
     base.OnCreate (bundle); 

     // Set our view from the "main" layout resource 
     SetContentView (Resource.Layout.Main); 

     listview = FindViewById(Resource.Id.listView1) as ListView; 
     adapter = new ArrayAdapter<string>(this, Android.Resource.Layout.SimpleListItem1); 

     for (int i = 0; i < 50; i++) 
      adapter.Add (i.ToString()); 

     listview.Adapter = adapter; 
     listview.Touch += ListenerOnTouch; 
    } 

    private void ListenerOnTouch(object sender, View.TouchEventArgs e) 
    { 
     // Delegate return type is void, so I can't return true/false 
    } 

從根本上說，我想要在此做實例是make是這樣的，如果我向上或向下拖動列表視圖，它會像平常一樣滾動，但是如果我向左或向右拖動它，則會執行其他操作。

我想，可能是e.Handled需要根據您的要求設置真/假。
