Listview listener沒有被調用

Question

我有按鈕，點擊後會顯示一個listview，點擊listview項時它必須在logcat上打印一些東西。我以這種方式實現了這一點，即列表視圖及其監聽器出現在按鈕onclick監聽器中。

一切都只是ListView的監聽工作以及是沒有得到所謂的（即，沒有什麼是對列表視圖項被點擊時在logcat的打印）

這裏是我的聽衆。

public class MyClickListener implements View.OnClickListener { 
    LinearLayout parent; 
    LayoutInflater layoutInflater; 
    Context context; 
    Home home; 

    @Override 
    public void onClick(View view) { 
     parent = (LinearLayout) home.findViewById(R.id.main_view); 
     View childLayout = layoutInflater.inflate(R.layout.mylayout, (ViewGroup) view.findViewById(R.id.list_layout)); 
     parent.addView(childLayout, 0); 

     LinearLayout layout = (LinearLayout) home.findViewById(R.id.main_view); 
     ListView list = (ListView) layout.findViewById(R.id.list); 
     list.setAdapter(new MyListAdapter(context)); 
     lsit.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
      @Override 
      public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) { 
       System.out.println("hello Android"); 
      } 
     }); 
    } 
} 

mylayout.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
       android:id="@+id/list_layout" 
       android:orientation="vertical" 
       android:layout_width="match_parent" 
       android:layout_height="wrap_content" 
       android:padding="15dp"> 

    <ListView 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:id="@+id/list" 
     android:padding="15dp" 
     android:divider="@android:color/transparent" 
     android:dividerHeight="5dp" 
     android:listSelector="@android:color/transparent" 
     android:cacheColorHint="@android:color/transparent"/> 
</LinearLayout> 

Home.java

public class Home extends Activity { 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState);  
     setContentView(R.layout.home); 
     Button button= (Button) findViewById(R.id.but); 
     button.setOnClickListener(new MyClickListener(this,this,layoutInflater)); 
    } 
} 

home.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
       android:layout_width="fill_parent" 
       android:layout_height="wrap_content" 
       android:gravity="center" 
       android:background="@color/background"> 
... 
    <LinearLayout 
     android:orientation="vertical" 
     android:layout_width="fill_parent" 
     android:layout_height="fill_parent" 
     android:layout_gravity="center" 
     android:id="@+id/main_view"> 
    </LinearLayout>

Answer 1

從您的onClick（）方法中刪除此代碼和實施的onClick（）方法之外。只需在那裏設置適配器，但實現是錯誤的onItemClickListener（）。

lsit.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
      @Override 
      public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) { 
       System.out.println("hello Android"); 
      } 
     }); 

Answer 2

請確保您的list_item_layout中沒有任何元素是竊取事件，如按鈕或帶有setClickable（true）的TextView。
