onListItemClick無法正常工作，如果圖像加載

我有一個自定義列表視圖有兩個textviews和圖像視圖。點擊顯示自定義對話框的每行iam。打開列表視圖後，單擊行iam可以查看對話框，而如果我滾動並單擊行對話框不顯示。onListItemClick無法正常工作，如果圖像加載

我onListItemclick代碼如下 `

final Dialog password = new Dialog(VCStegoInboxWithOutCheckboxes.this); 
     password.setContentView(R.layout.dialog); 
     password.setTitle("Enter your Password"); 

     final EditText getPassword = (EditText) password 
       .findViewById(R.id.edconfirmpwd); 
     Button okButton = (Button) password.findViewById(R.id.ok); 
     okButton.setOnClickListener(new OnClickListener() { 
      @Override 
      public void onClick(View v) { 

       String ConfirmCode = getPassword.getText().toString(); 
       SharedPreferences settingsActivity = getSharedPreferences(
         "UserName", Activity.MODE_PRIVATE); 
       String Password = settingsActivity.getString("Password", null); 

       if (ConfirmCode.equals(Password)) { 
             Intent showMsgIntent = new Intent(); 
         showMsgIntent.setClass(getApplicationContext(), 
           VCStegoShowMessageScreen.class); 

         startActivity(showMsgIntent); 


       } else { 
        Toast.makeText(getBaseContext(), "InvalidPassword", 
          Toast.LENGTH_SHORT).show(); 

       } 

       password.dismiss(); 

      } 
     }); 
     Button cancelButton = (Button) password.findViewById(R.id.cancel); 
     cancelButton.setOnClickListener(new OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       System.out.println("Entered on cancel button clicked"); 
       password.dismiss(); 

      } 
     }); 
     password.show(); 

    }

我觀察到的另一件事是，如果它是一個TextView（而不是ImageView的），即使如果我滾動亞姆能夠爲每行顯示的對話框。

我的適配器方法

public class InboxAdapter extends BaseAdapter { 
    private LayoutInflater inflater; 
    private TextView Tvname, TVtimeStamp; 
    private ImageView IVmsg; 

    public InboxAdapter(Context context, List<VCStegoInboxList> inboxList) { 
     inflater = LayoutInflater.from(context); 
     VCStegoInboxWithOutCheckboxes.Inboxlist = inboxList; 
    } 
    public class ViewHolder{ 
      private TextView Tvname; 
      private TextView TVtimeStamp;    
      private ImageView IVmsg; 
      } 

    public int getCount() { 
     return VCStegoInboxWithOutCheckboxes.Inboxlist.size(); 
    } 

    // @Override 
    public Object getItem(int position) { 
     return VCStegoInboxWithOutCheckboxes.Inboxlist.get(position); 
    } 

    // @Override 
    public long getItemId(int position) { 
     return position; 
    } 

    // @Override 
    public View getView(final int position, View convertView, 
      ViewGroup parent) { 

     ViewHolder holder; 

      if (convertView==null){ 

      holder = new ViewHolder(); 

     convertView = inflater.inflate(R.layout.inboxtextviews, null); 
     Tvname = (TextView) convertView.findViewById(R.id.tvinboxname); 

     IVmsg = (ImageView) convertView.findViewById(R.id.tvinboxmsg); 



     TVtimeStamp = (TextView) convertView.findViewById(R.id.tvtimeStamp); 

     convertView.setTag(holder); 
     }else{ 

     holder = (ViewHolder) convertView.getTag(); 
     } 
      Tvname.setText(VCStegoInboxWithOutCheckboxes.Inboxlist 
       .get(position).getname()); 
      IVmsg.setImageBitmap(VCStegoInboxWithOutCheckboxes.Inboxlist.get(
        position).getBitmap()); 
      TVtimeStamp.setText(VCStegoInboxWithOutCheckboxes.Inboxlist.get(
        position).getTimeStamp()); 
     return convertView; 
    } 

}

我的XML文件是

<?xml version="1.0" encoding="utf-8"?>

<TextView 
    android:id="@+id/tvinboxname" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:textAppearance="?android:attr/textAppearanceMedium" /> 

<ImageView 
    android:id="@+id/tvinboxmsg" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content"   
    android:layout_below="@+id/tvinboxname" 

    android:contentDescription="@string/contentDes" /> 

<TextView 
    android:id="@+id/tvtimeStamp" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_alignParentRight="true" 
    android:layout_below="@+id/tvinboxmsg" 
    android:textAppearance="?android:attr/textAppearanceSmall" />

您需要發佈所有列表代碼，因爲它似乎問題與您的列表，而不是您的對話框。 – Barak

您的listitem點擊在哪裏？ – kyogs

發佈適配器方法和xml。其實如果我用列表項目替換圖像視圖，然後IAM沒有得到任何問題。並與圖像視圖列表顯示正確。只有在滾動iam後才能獲得對話。 – user1203673

給ID像

根佈局ID

<RelativeLayout 
    android:id="@+id/root" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content"> 

<your TextView/> 
<your ImageView/> 
<your TextView/> 

</RelativeLayout>

獲取根在適配器類像

root = (RelativeLayout) convertView.findViewById(R.id.root);

寫的onclick聽衆上述return convertView;行，你的適配器類的onclick監聽器是這樣

root.setOnClickListener(new OnClickListener() { 
      @Override 
      public void onClick(View v) { 
//toast display dialog code here 
} 
});
