Android自定義ArrayAdapter Listview不可點擊與異步任務

Question

我一直堅持這個問題近一天了，並嘗試了無數以前的帖子在堆棧溢出，在線教程等，但似乎沒有在我的情況下工作。我已經嘗試設置focusable，focusable touch和clickable爲false在每行列表項中的所有textview，在list_item_main.xml的相對佈局中設置android：descendantFocusability =「blocksDescendants」，但沒有任何工作。任何幫助將真正被讚賞！感謝的設置如下：

tab.xml（佈局列表視圖）：

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:orientation="vertical"> 

<ListView 
    android:layout_width="wrap_content" 
    android:layout_height="400dp" 
    android:clickable="true" 
    android:id="@+id/android:list" 
    android:layout_centerHorizontal="true" 
    android:layout_alignParentTop="true" /> 
</LinearLayout> 

list_item_main.xml（每一行項目）：

<?xml version="1.0" encoding="utf-8"?>

DealAdapter：

public class DealAdapter extends ArrayAdapter<Offer2SaleTransaction> {

private static final Logger logger = Logger.getLogger(DealAdapter.class.getName()); 


public DealAdapter(List<Offer2SaleTransaction> activeDeals, Context ctx) {

    this.activeDeals = activeDeals; 
    this.context = ctx;

    if (activeDeals != null) 
     return activeDeals.size();

    return v;

    lView.setOnItemClickListener(this); 

    // Exec async load task

public void onItemClick(AdapterView<?> arg0, View arg1, int position, long id) { 
    Toast.makeText(getActivity(), "PLEASE WORK",Toast.LENGTH_LONG).show();

     else

      adpt.setActiveDeals(result); 
      adpt.notifyDataSetChanged(); 
     } 
    } 
}} 

Answer 1

，因爲要擴展ListFragment，你必須重寫onListItemClick，並在地方onItemClick使用它。

• 拆下實現OnItemClickListener
• 刪除lView.setOnItemClickListener（本）;
• 刪除onItemClick

然後

@Override 
public void onListItemClick(ListView l, View v, int position, long id) {   
    Toast.makeText(getActivity(), "PLEASE WORK",Toast.LENGTH_LONG).show();k(l, v, position, id); 
}
