錯誤開始新的活動

Question

在我的應用程序我m顯示列表中的Tabview，在一個選項卡時，我試圖啓動一個新的活動onclick列表視圖觸摸事件。我想在網頁視圖中開始一項新活動。

showNewsListView.setAdapter(listAdapter); 
showNewsListView.setOnItemClickListener(new OnItemClickListener(){ 
    public void onItemClick(AdapterView<?> arg0, View arg1, int position, 
     long arg3) { 
      Log.v("status ","tab on position"+position); 
      Intent myIntent = new Intent(BizTab.this, MainView.class); 
      startActivity(myIntent); 

      } 
      }); 

getUrlData(baseUrl); 

} 

，如果我跑這麼多的代碼的應用程序崩潰，所以我剛剛找到自己的解決方案，我應該在asyncrouniously開始一個新的活動所以現在即時通訊做這個

showNewsListView.setAdapter(listAdapter); 
    showNewsListView.setOnItemClickListener(new OnItemClickListener(){ 
    public void onItemClick(AdapterView arg0, View arg1, int position, long arg3) { Log.v("status ","tab on position"+position); 

     new ShowFullNews().execute(); 
     } 
     }); 
getUrlData(baseUrl); 

}` 

`showNewsListView.setAdapter(listAdapter); 
showNewsListView.setOnItemClickListener(new OnItemClickListener(){ 
    public void onItemClick(AdapterView<?> arg0, View arg1, int position, 
     long arg3) { 
      Log.v("status ","tab on position"+position); 

     new ShowFullNews().execute(); 
     } 
     }); 
getUrlData(baseUrl); 

}` 

然後還我的代碼崩潰和不給錯誤只是給這兩個警告

如果我在兩個地方開始一個新的活動onTouch和後執行然後我的代碼是woking，但在這裏它首先顯示屏幕，然後它自動去刷新屏幕，這不看起來不錯。所以如何避免它。請幫我和plese忽略語法錯誤我的工作代碼是

public void onItemClick(AdapterView<?> arg0, View arg1, int position, 
     long arg3) { 
      Log.v("status ","tab on position"+position); 

      //set bundle to send data into other activity 
      b.putInt("total", 10); 
      b.putInt("position",position); 
      b.putStringArray("allurls", allsNewsUrls); 
      b.putString("returnname", "BizTab"); 
      b.putString("footertext","Biz"); 
      b.putInt("tabid", 3); 

      Intent myIntent = new Intent(BizTab.this, MainView.class); 
      myIntent.putExtras(b); 
      startActivity(myIntent); 
      new ShowFullNews().execute(); 
     } 
     }); 

protected void onPostExecute(Long result) { try { 
    Intent myIntent2 = new Intent(BizTab.this, MainView.class); 

startActivity(myIntent2); 


} catch (Exception e) { 
Log.v("error","error in starting new activity"); 
e.printStackTrace(); 
} 

    }` 

日誌生成和我的應用程序正在自動關閉。

相反的：

Intent myIntent = new Intent(BizTab.this, MainView.class); 
myIntent.putExtras(b); 
startActivity(myIntent); 

嘗試用：

Intent myIntent = new Intent(getBaseContext(), BizTab.this); <!-- or MainView.class--> 
myIntent.putExtras(b); 
myIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
startActivity(myIntent);
