Android listview onclicklistener活動

Question

我想，如果我點擊'Leerlingenraad'的列表視圖，他打開Leerlingenraad.xml類的Leerlingenraad類，如果我點擊聯繫人，他打開類與contact.xml聯繫我已經找到這很多話題，但它不會工作。有人知道我的腳本中出了什麼問題嗎？請不要評價。

我假設你已經有了詳細的活動，我把它叫做OndernemingDetailActivity

在你的ListView活動：

lv.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
     @Override 
     public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) { 

      Intent in = new Intent(this, OndernemingDetailActivity.class); 
      //Send onderneming 
      in.putExtra("selected_onderneming", adapter.getItem(i)); 
      startActivity(in); 
     } 
    }); 

然後在您的詳細信息視圖，你會得到「selected_onderneming」從包像這樣：

String selectedOnderneming; 
Bundle extras = intent.getExtras(); 
    if(extras != null) 
     onderneming = extras.getString("selected_onderneming"); // retrieve the selected onderneming 

這是爲了讓演員出最快捷的方式捆綁。檢查出this發佈一個更健壯和安全的方式來這樣做。

然後，您可以顯示您選擇的'選擇開始'的數據。我希望這回答了你的問題。
