我的列表活動無法打開

基本上，我的博愛活動列表活動不會從我的活動列表中打開。我不知道爲什麼，但如果你能幫助我，我確實有日誌貓和代碼。謝謝。我的列表活動無法打開

我蟒科類：

/* 
* This class is a list to contain 
* all of the classes for the individual species. 
*/ 


package com.xeecros.reptilekeeper; 

import android.app.ListActivity; 
import android.content.Intent; 
import android.os.Bundle; 
import android.view.View; 
import android.widget.ArrayAdapter; 
import android.widget.ListView; 

public class Boidae extends ListActivity { 

    String boaspecies[] = {"Charina bottae"}; 


    @Override 
    protected void onCreate(Bundle savedInstanceState) { 

     super.onCreate(savedInstanceState); 
     setListAdapter(new ArrayAdapter<String>(Boidae.this, 
       android.R.layout.simple_list_item_1, boaspecies)); 
    } 

    @Override 
    protected void onListItemClick(ListView l, View v, int position, long id) { 

     super.onListItemClick(l, v, position, id); 
     String localposm = boaspecies[position]; 
     try{ 
      Class ourclass = Class.forName("com.xeecros.reptilekeeper" + localposm); 
      Intent bintent = new Intent(Boidae.this, ourclass); 
      startActivity(bintent); 
      }catch (ClassNotFoundException e){ 
       e.printStackTrace(); 
      } 
    } 





}

我serpente類：

package com.xeecros.reptilekeeper; 

import android.app.ListActivity; 
import android.content.Intent; 
import android.os.Bundle; 
import android.view.View; 
import android.widget.ArrayAdapter; 
import android.widget.ListView; 

public class Serpentes extends ListActivity { 

    String snakefam[] = {"Boidae", "Colubridae", 
      "Elapidae", "Pythonidae", "Viperidae"}; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 

     super.onCreate(savedInstanceState); 
     setListAdapter(new ArrayAdapter<String>(Serpentes.this, 
       android.R.layout.simple_list_item_1, snakefam)); 
    } 

    @Override 
    protected void onListItemClick(ListView l, View v, int position, long id) { 

     super.onListItemClick(l, v, position, id); 
     String localposm = snakefam[position]; 
     try{ 
     Class ourclass = Class.forName("com.xeecros.reptilekeeper" + localposm); 
     Intent sintent = new Intent(Serpentes.this, ourclass); 
     startActivity(sintent); 
     }catch (ClassNotFoundException e){ 
      e.printStackTrace(); 
     } 
    } 

}

另外，我有一個問題要問：我如何改變列表的外觀，因爲我不能使用XML，因爲它是一個ArrayAdapter。

謝謝。

變化通過把這個代替

Class ourclass = Class.forName("com.xeecros.reptilekeeper." + localposm);

注意以下行

Class ourclass = Class.forName("com.xeecros.reptilekeeper" + localposm);

。失蹤的錯誤日誌表明它：

ClassNotFoundException: com.xeecros.reptilekeeperBoidae

那裏的愚蠢錯誤謝謝你，但你也知道我會如何改變外觀。 – tridianprime 2013-04-23 19:57:46

我確實對此有點懷疑，但那並沒有想到。下次不好意思。 – tridianprime 2013-04-23 19:58:58

你是什麼意思？你總是可以提出有關外觀的新問題。 – Benoit 2013-04-23 19:59:09

看這（在類蟒科）：

String boaspecies[] = {"Charina bottae"}; 
.... 
String localposm = boaspecies[position]; 
... 
Class ourclass = Class.forName("com.xeecros.reptilekeeper" + localposm);

這可不行，因爲Charina bottae不能是一個類名。

最後你錯過了點（在課堂蟒科和蛇亞）：

Class ourclass = Class.forName("com.xeecros.reptilekeeper." + localposm);

乾杯！

不錯的地方Boidae班也有錯誤，但問題是無法啓動Boidae班。無論如何+1更多的錯誤 – Benoit 2013-04-23 20:03:34
