ListView對選擇沒有反應

我有一個ListView在一個活動中，確實注意到被選中的反應。這可能是一件小事，因爲我對Android比較陌生，但似乎無法自己弄清楚。ListView對選擇沒有反應

我的onLoad（）在我的活動負載是這樣的：

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

    Bundle extras = getIntent().getExtras(); 
    if(extras != null){ 
     if(extras.containsKey("categoryId")) categoryId = extras.getLong("categoryId"); 
    } 

    ListView lv = (ListView) findViewById(R.id.article_list_activity); 
    iDomsAndroidApp app = ((iDomsAndroidApp) getApplicationContext()); 

    try { 
     objects = app.getDataManager().getArticlesForCategory(categoryId, 15); 
     adapter = new ArticleListAdapter(this, R.layout.article_list_cell, objects, categoryId); 
     lv.setOnScrollListener(adapter); 
     lv.setAdapter(adapter); 
    } catch (Exception e){ 
     Log.e(iDomsAndroidApp.TAG, "Error " + e.getMessage(), e); 
    } 

    lv.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
     public void onItemClick(AdapterView<?> parent, View view, 
           int position, long id) { 
      // When clicked, show a toast with the TextView text 
      Toast.makeText(getApplicationContext(), objects.get(position).getTitle(), 
        Toast.LENGTH_SHORT).show(); 


      Intent intent = new Intent(view.getContext(), ArticleActivity.class); 
      intent.putExtra("articleId", objects.get(position).getId()); 
      startActivity(intent); 


     } 
    }); 

}

然後在我的適配器（ArrayAdapter）

public View getView(int i, View view, ViewGroup viewGroup) { 
     LayoutInflater inflater = (LayoutInflater)getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE); 

     if (view == null) { 
      view = inflater.inflate(R.layout.article_list_cell, viewGroup, false); 
     } 

     Article article = getItem(i); 
     TextView titleText = (TextView)view.findViewById(R.id.article_list_titleText); 

     try{ 
     TextView siteText = (TextView)view.findViewById(R.id.article_list_siteText); 
     TextView summaryText = (TextView)view.findViewById(R.id.article_list_summaryText); 
      RadioButton readBttn = (RadioButton) view.findViewById(R.id.article_list_readButton); 
      TextView updatedText = (TextView) view.findViewById(R.id.article_list_updatedText); 
      TextView date = (TextView) view.findViewById(R.id.article_cell_date); 

      titleText.setText(article.getTitle()); 
      siteText.setText(article.getSite().getName()); 
      summaryText.setText(article.getSummary()); 

      date.setText(DateFormat.getMediumDateFormat(this.getContext()).format(article.getPubDate())); 
      if(article.getRead()){ 
       readBttn.setChecked(false); 
      } else { 
       readBttn.setChecked(true); 
      } 

      if(article.getUpdated()){ 
       updatedText.setVisibility(View.VISIBLE); 
      } else { 
       updatedText.setVisibility(View.INVISIBLE); 
      } 

     } catch (Exception e) { 
      titleText.setText("Error loading article content!"); 
     } 

     return view; 
    }

article_list_cell.xml：

你可以嘗試更改列表的id到xml中的android：id/list，並將其作爲android.R.id.list ..雖然不知道是否該問題b問題 –

我的猜測是當您點擊列表項目時，RadioButton需要關注。

所以加

android:descendantFocusability="blocksDescendants"

中根元素article_list_cell.xml

編輯：

焦點和focusableintouchmode cud也設置爲false –

試過了，但沒有什麼區別。同時禁用單選按鈕而不更改。我用article_list_cell.xml文件更新了問題 –

@ LuukD.Jansen將檢查並恢復 – Raghunandan

嘗試@Override添加到您的onItemClick方法

lv.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
    @Override 
    public void onItemClick(AdapterView<?> parent, View view, 
          int position, long id) {}

當實現接口方法時不允許 –

l1.setOnItemClickListener(new OnItemClickListener() { 
       public void onItemClick(AdapterView<?> parent, View view, 
        int position, long id) { 
       // TODO Auto-generated method stub 
       String name=(String)parent.getItemAtPosition(position); 

       Toast.makeText(getBaseContext(), name, Toast.LENGTH_LONG).show(); 
        Intent i = new Intent(getBaseContext(),Webview.class); 
        //i.putExtra("USERNAME", name); 
        startActivity(i); 

       } 
      });
