當點擊列表視圖項目沒有執行任何操作和LogCat顯示ViewPostImeInputStage ACTION_DOWN

我試圖創建一個活動，搜索拋出listview項目。我創建了一個switch與caseCategory其中Category是在main<string-array>一個項目，但是當我點擊不執行任何操作的項目和logcat的顯示這條消息 - > 04-29 20：20：00.380：d/ViewRootImpl（30869）：ViewPostImeInputStage ACTION_DOWN當點擊列表視圖項目沒有執行任何操作和LogCat顯示ViewPostImeInputStage ACTION_DOWN

任何人都可以告訴我解決方案嗎？

您必須在ListView上設置itemClickListener。 http://stackoverflow.com/questions/17851687/how-to-handle-the-click-event-in-listview-in-android –

我在代碼中有這種方法，但它不響應，也看到LogCat錯誤@Sammy T – Doglas

那麼它看起來像你的switch-case沒有被調用然後。嘗試將您的switch語句替換爲if語句。使用.equals()是比較字符串更可靠的方法。

TextView thisTextView = (TextView)view.findViewById(R.id.listview_item_title); 
String text = (String)thisTextView.getText(); 

if(text.equals("Category")){ 
    Intent i=new Intent(Search.this, MainActivity.class); 
    startActivity(i); 
}else{ 
    Toast.makeText(Search.this,"What's my text: " + text, Toast.LENGTH_LONG).show(); 
}

仍然不工作！：/在LogCat中的相同msg - >'04-30 21：16：03.920：D/ViewRootImpl（17890）：ViewPostImeInputStage ACTION_DOWN' – Doglas

嘗試使用此新編輯來代替之前的if語句。通過這種方式，它應該告訴你即使由於某種原因失敗了，也會返回哪些文本。我是否認爲你有TextViews填充你的ListView？ –

getActivity（）方法是什麼（未定義）？我嘗試設置'getApplicationContext（）'而不是'getActivity（）'並運行該應用程序，當點擊該項目時，程序停止'不幸已停止' – Doglas

您有onItemClick但您在ListView上設置Click Listener時沒有設置它。把它放在你的setOnItemClickListener

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
     @Override 
     public void onItemClick(AdapterView<?> parent, View view, int position, 
       long id) { 
      //whatever you want to happen when an item is clicked 
     } 
    });

我把它稱爲這個>> listView.setOnItemClickListener（this）;'在'doListSearch（）'和'doListNormal（）'方法 – Doglas

是的，我看到了，但我認爲這可能是你的問題。按照我的建議來嘗試。 –

我已經試過了，仍然沒有工作！ – Doglas
