嘿,我今天刚开始ios编程,我正面临着这个错误.

PLZ帮我删除此错误

PLZ建议我一些不错的ios开发人员教程

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

@end


#import <UIKit/UIKit.h>

@interface ViewController : UIViewController
@property (weak, nonatomic) IBOutlet UITextField *txtUsername;
@property (weak, nonatomic) IBOutlet UITextField *txtPassword;
- (IBAction)loginClicked:(id)sender;
- (IBAction)backgroundClick:(id)sender;


@end

我有我的自定义列表视图,在每行的末尾我都有ImageView从列表中删除该行,但是当我点击这个图像时,我得到"Arryindesoutofboundexception:length = 681 indez = -1"

帮我

private OnClickListener imageviewClickListener = new OnClickListener() {
  @Override
  public void onClick(View v) 
  {
      int index;
        index=listView.getSelectedItemPosition();//itemsListView is the listview
        dataAdapter.remove(topicsList.get(index));
        topicsList.clear();
        dataAdapter.notifyDataSetChanged();


  }
};

我TextView在实时更新时遇到问题.我想更新TextView的ListView实时与自定义适配器.我有我的套接字I/O处理程序,我收到一个JSON消息.我想解析这个JSON并将该文本放入特定的列表行setText().如何获取该ListView行的索引并更新它TextView？

responseid=object.getString("ResponseID");
if(responseid!=null){
    for(int j=0;j<countryList.size();j++){
        //If the countryList row match then i want to update the textView of that particular row
        if(countryList.get(j).getName().equals(caseid)) {                        
            int oldcount = Integer.parseInt((dataAdapter.findViewById(R.id.replycount)).getText().toString());
            int total=oldcount+1;
            (dataAdapter.findViewById(R.id.replycount)).setText(Integer.toString(total));
            dataAdapter.notifyDataSetChanged();
        }
    }    
}
