在列表视图的每一行中添加单击Listner

Question

我想在android listview项目中添加可点击的链接，我在listview的每一行中添加了5个项目，并且我只希望两个项目在webview中使用putextras（）intents创建可点击和打开的sholud我正在使用自定义适配器请任何人hlep我。

假设“链接1”是：“视图校对”（proofinglink）（在textview中）和“链接2”是：“获取更多详细信息”（附加链接）我想要点击链接1时，它应该在webview中打开在他自己的网址后面。当我点击链接2时：它也应该在他自己给定的网址中的webview中打开。使用putextras（）意图 这里是我的代码。

         Intent intent = new Intent(getApplicationContext(), 
      Tipster_webview.class); 

         intent.putExtra("gettproofing_URl",getproofing); 
         intent.putExtra("getsiteURL",getsite); 
         startActivity(intent);

       }); 

     } 

    } 

    LoginAsync la = new LoginAsync(); 
    la.execute(); 

    } 

我想“proofinglink”和“附加链接”可点击以及开放中的WebView

这里是自定义适配器

   public class Tipster_adapter extends BaseAdapter { 
       Context context; 
      ArrayList<Tipster_list>tipslist; 

       public Tipster_adapter(Context context, 
    ArrayList<Tipster_list> tipslist) { 
    super(); 
    this.context = context; 
    this.tipslist = tipslist; 
} 



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

    @Override 
    public Object getItem(int position) { 
    // TODO Auto-generated method stub 
    return position; 
    } 

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

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 
    if(convertView==null){ 

     LayoutInflater inflater=(LayoutInflater) 
    context.getSystemService(context.LAYOUT_INFLATER_SERVICE); 
     convertView=inflater.inflate(R.layout.activity_tipster_adapter 
       ,null); 


     ImageView icon= 
     (ImageView)convertView.findViewById(R.id.icon_tipsterIconID); 

     TextView name=(TextView) 
      convertView.findViewById(R.id.txt_name_tipsterID); 
     TextView total=(TextView) 
    convertView.findViewById(R.id.txt_total_tipsterID); 
     TextView proofingLink=(TextView) 
    convertView.findViewById(R.id.txt_proofinglink_tipsterID); 
     TextView siteLink=(TextView) 
    convertView.findViewById(R.id.txt_sitelink_tipsterID); 

     Tipster_list services=tipslist.get(position); 
     Picasso.with(context).load(services.getImage()).into(icon); 
     Log.d("Url",services.getImage()); 
     name.setText(services.getName()); 
     total.setText(services.getTotal()); 
     proofingLink.setText(services.getProofinglink()); 
     siteLink.setText(services.getSitelink()); 

     } 



    return convertView; 
    } 

} 

Answer 1

你的代码是确定需要在添加监听你的适配器为您想要触发的视图例如

inside your adapter getview method paste this code like this 

@Override 
public View getView(int position, View convertView, ViewGroup parent) { 
    Tipster_list services=tipslist.get(position); 
    if(services!=null){ 
     LayoutInflater inflater=(LayoutInflater) context.getSystemService(context.LAYOUT_INFLATER_SERVICE); 
     convertView=inflater.inflate(R.layout.activity_custom_adapter,null); 
     ImageView icon=(ImageView)convertView.findViewById(R.id.icon_tipsterIconID); 
     TextView name=(TextView) convertView.findViewById(R.id.txt_name_tipsterID); 
     TextView total=(TextView) convertView.findViewById(R.id.txt_total_tipsterID); 
     TextView proofingLink=(TextView) convertView.findViewById(R.id.txt_proofinglink_tipsterID); 
     TextView siteLink=(TextView) convertView.findViewById(R.id.txt_sitelink_tipsterID); 
     Picasso.with(context).load(services.getImage()).into(icon); 
     Log.d("Url",services.getImage()); 
     name.setText(services.getName()); 
     total.setText(services.getTotal()); 
     proofingLink.setText(services.getProofinglink()); 
     siteLink.setText(services.getSitelink()); 
     convertView.setTag(position); 
     String getName=services.getName(); 
     final String getproofing=services.getProofinglink(); 
     final String getsite=services.getSitelink(); 
     proofingLink.setOnClickListener(new View.OnClickListener() { 

      @Override 
      public void onClick(View v) { 
       // TODO Auto-generated method stub 
       Intent intent = new Intent(context, Tipster_webview.class); 
       intent.putExtra("gettproofing_URl",getproofing); 
       context.startActivity(intent); 
      } 
     }); 
     siteLink.setOnClickListener(new View.OnClickListener() { 

         @Override 
         public void onClick(View v) { 
          // TODO Auto-generated method stub 
          Intent intent = new Intent(context, Tipster_webview.class); 
          intent.putExtra("site",getsite); 
          context.startActivity(intent); 
         } 
        }); 
     } 



return convertView; 
} 

Answer 2

TextView proofingLink=(TextView) convertView.findViewById(R.id.txt_proofinglink_tipsterID); 

    proofingLink.setOnClickListener(new OnItemClickListener() { 

    @Override 
    public void onClick(View arg0) { 

     String url = services.getProofinglink(); 
     Intent i = new Intent(Intent.ACTION_VIEW); 
     i.setData(Uri.parse(url)); 
     startActivity(i); 
      } 
     }); 

Answer 3

TextView proofingLink=(TextView) 
convertView.findViewById(R.id.txt_proofinglink_tipsterID); 
proofingLink.setOnClickListener(new OnClickListener() { 
    @Override 
    public void onClick(View v) { 
     // TODO Auto-generated method stub 
    } 
}); 
TextView siteLink=(TextView) 
convertView.findViewById(R.id.txt_sitelink_tipsterID); 
siteLink.setOnClickListener(new OnClickListener() { 
    @Override 
    public void onClick(View v) { 
     // TODO Auto-generated method stub 

    } 
});
