我有一個問題，我下面的代碼：Android的gridview的問題

public class RestListActivity extends Activity{ 
    ImageButton [] buttons; 
    RelativeLayout rl; 
    int restCount=0; 
    Resources a; 
    int resIndex=0; 
    boolean resFound=false; 
    int last; 
    int resCount=0; 
    GridView gv; 
    // TODO Auto-generated constructor stub 
    @Override 
    public void onCreate (Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 

     setContentView(R.layout.restlist); 
     rl = (RelativeLayout) findViewById(R.id.relativeLayoutRest); 

     Log.i("asd","asd"); 

     gv=new GridView(this); 
     a=this.getResources(); 
     int i=0x7f020000; 
     boolean done=true; 

     Log.i("asd","asd"); 
     try 
     { 
      for (i=0x7f020000 ;done&&i<0x7f020040;i++) 
      { 
       Log.i("rest buttons","----"+i); 
       String name=a.getResourceName(i); 
       name=name.substring(name.indexOf(':')+1); 
       name=name.substring(9); 
       if(name.startsWith("rest")) 
       { 
        if(!resFound) 
        { 
         resIndex=i; 
         resFound=true; 
        } 
        Log.i("rest buttons",name); 

        resCount++; 
       } 
      } 
     } 
     catch(Exception e) 
     { 
      last=i; 
      Log.i("LAST",i+""); 
      done=false; 
      e.printStackTrace(); 
     } 
     buttons=new ImageButton[resCount]; 
     Button orderButton = (Button)findViewById(R.id.adbutton); 
     orderButton.setText("REKLAMLAR"); 
     orderButton.setOnClickListener(new View.OnClickListener() { 
      public void onClick(View view) { 
       Log.i("ACTION","AD BUTTON CLICKED"); 
       try 
       { 
        Intent i = new Intent(RestListActivity.this,AVMSystemActivity.class); 
        startActivity(i); 
       } 
       catch(Exception e) 
       { 
        Log.i("cort",e.toString()); 
       } 
      } 
     }); 
     if(rl==null) 
      Log.i("------------","RLOUT NULL AGA"); 
     else 
      Log.i("------------","RLOUT EXISTS AGA"); 
     //************************************************************************************

     for(int j=resIndex,f=0;j<resIndex+resCount;j++,f++)

        buttons[f].setImageDrawable(a.getDrawable(j)); 
        buttons[f].setOnClickListener(new View.OnClickListener() {

第一個異常告訴你的資源，那就是在R文件中提及，但在res文件夾不存在。這意味着您應該清理並重建項目以重新生成R文件。希望這個對你有幫助。

是，首先清理項目。您的代碼中的for (i=0x7f020000 ;done&&i<0x7f020040;i++)部分也非常危險，因爲您的資源ID將在每次構建後發生更改，並且在項目中添加另一個ID後，您肯定會失敗。

你也可能需要重新考慮你的設計。爲什麼在ListView中使用按鈕？您應該將不僅僅是圖像，實施您的Activity的onItemClickListener接口和攔截在​​方法，當用戶在ListView點擊的項目。

感謝您的回覆。我清理和重建項目沒有任何改變。然後我只是評論了行gv.addView（按鈕[f]，f）; 然後輸出是完美的。資源名稱列表等。當我添加到gridview時，我做錯了什麼。爲什麼它不起作用？這就是我想知道的：/ – dramaticlook
