Gridview的onclick監聽器不工作

我使用gridview的佈局，它不工作後的列表中的網格視圖項目，它顯示「throwIndexOutOfBoundsException」在logcat error.without onclick函數，如果我使用敬酒其工作，如果我給爲下一個活動的onlcick功能它不工作Gridview的onclick監聽器不工作

Gridviewadapter.java

public class GridviewAdapter extends BaseAdapter 
{ 
    private ArrayList<String> listginfy; 
    private ArrayList<Integer> listimage; 
    private Activity activity; 

    public GridviewAdapter(GinfyActivity ginfyActivity,ArrayList<String> listginfy, ArrayList<Integer> listimage) { 
     super(); 
     this.listginfy = listginfy; 
     this.listimage = listimage; 
     this.activity = (Activity) ginfyActivity; 
    } 

    @Override 
    public int getCount() { 
     // TODO Auto-generated method stub 
     return listginfy.size(); 
    } 

    @Override 
    public String getItem(int position) { 
     // TODO Auto-generated method stub 
     return listginfy.get(position); 
    } 

    public int getItemId() { 
     // TODO Auto-generated method stub 
     return 0; 
    } 

    public static class ViewHolder 
    { 
     public ImageView imgViewGinfy; 
     public TextView txtViewTitle; 
    } 

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 
     // TODO Auto-generated method stub 
     ViewHolder view; 
     LayoutInflater inflator = activity.getLayoutInflater(); 

     if(convertView==null) 
     { 
      view = new ViewHolder(); 
      convertView = inflator.inflate(R.layout.gridview_row, null); 

      view.txtViewTitle = (TextView) convertView.findViewById(R.id.textView1); 
      view.imgViewGinfy = (ImageView) convertView.findViewById(R.id.imageView1); 

      convertView.setTag(view); 
     } 
     else 
     { 
      view = (ViewHolder) convertView.getTag(); 
     } 

     view.txtViewTitle.setText(listginfy.get(position)); 
     view.imgViewGinfy.setImageResource(listimage.get(position)); 

     return convertView; 
    } 

    @Override 
    public long getItemId(int arg0) { 
     // TODO Auto-generated method stub 
     return 0; 
    } 


}

Mainactivity.java

@Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.home_ginfy); 

     prepareList(); 

     // prepared arraylist and passed it to the Adapter class 
    mAdapter = new GridviewAdapter(this,listginfy, listimage); 

     // Set custom adapter to gridview 
     gridView = (GridView) findViewById(R.id.gridView1); 
     gridView.setAdapter(mAdapter); 

     // Implement On Item click listener 
     gridView.setOnItemClickListener(new OnItemClickListener() 
     { 
      @Override 
      public void onItemClick(AdapterView<?> a, View v, int position, long id) { 


       mAdapter = results.get(position); 

       switch(mAdapter.getItemId()) 
       { 
       case 1: 
       Intent newActivity = new Intent(GinfyActivity.this,MainActivity.class); 
       startActivity(newActivity); 
       break; 

       case 2: 
       Intent new1Activity = new Intent(GinfyActivity.this,AndroidTabLayoutActivity.class); 
       startActivity(new1Activity); 
       break; 
       default: 
        Toast.makeText(GinfyActivity.this, "Wrong Input", Toast.LENGTH_LONG).show(); 
        } 
      } 
     }); 

    } 

    public void prepareList() 
    { 
     listginfy = new ArrayList<String>(); 

     listginfy.add("Prayers"); 
     listginfy.add("Poojaroom"); 


     listimage = new ArrayList<Integer>(); 
     listimage.add(R.drawable.ginfyprayer); 
     listimage.add(R.drawable.poojaroom1); 

    } 


}

克的ONCLICK功能idview不起作用這裏我也發佈我的XML佈局。

<RelativeLayout 
    android:id="@+id/relativeLayout1" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"

發佈您的logcat。 –

'mAdapter = results.get（position）;'？這一行沒有意義。 'mAdapter.getItemId（）'這個將永遠執行'default：'case – Blackbelt

你可以發佈你的xml佈局嗎？ – user936414

你有很多錯誤在你的代碼..（如android:clickable="True"在佈局>>刪除）

只是爲了測試，以替換代碼：

// Implement On Item click listener 
     gridView.setOnItemClickListener(new OnItemClickListener() 
     { 
      @Override 
      public void onItemClick(AdapterView<?> a, View v, int position, long id) { 



      switch(position) 
      { 
      case 1: 
      Intent newActivity = new Intent(GinfyActivity.this,MainActivity.class); 
      startActivity(newActivity); 
      break; 

      case 2: 
      Intent new1Activity = new Intent(GinfyActivity.this,AndroidTabLayoutActivity.class); 
      startActivity(new1Activity); 
      break; 
      default: 
       Toast.makeText(GinfyActivity.this, "Wrong Input", Toast.LENGTH_LONG).show(); 
       } 
     } 
    });

的getItemId您的適配器總是返回0 ..

，它的工作原理，但點擊第一張圖片時顯示錯誤輸入，點擊第二張圖片後打開mainacitty， –

實際上我在gridview中給出了兩張圖片，我希望首先點擊它必須去主要活動的圖像，第二個圖片必須去androidtablayoutactivity，以什麼方式我可以作爲開關，它將如何按照他們的點擊花花公子@Pauland –

lol ...位置從0開始索引...現在，只是將案例1替換爲案例0和案例2的案例1; – Pauland

更換

mAdapter = results.get(position); 

       switch(mAdapter.getItemId())

通過

switch(position)

沒有onclick函數不工作，它的靜態，點擊gridview之後它沒有做任何事 –

花花公子它不工作 –

我一直在使用這樣的事情。在你的情況下，這應該工作。
