Linkview ListView中的Android

Question

我想在列表视图中显示的网址，当在URL用户点击它应该在浏览器中打开，我的代码是

package com.app.adapter; 

import com.app.myTracker.UI.R; 
import com.app.utils.Logger; 

import android.content.Context; 
import android.text.Html; 
import android.text.method.LinkMovementMethod; 
import android.text.method.MovementMethod; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.BaseAdapter; 
import android.widget.ImageView; 
import android.widget.TextView; 

public class BrowserLogListAdapter extends BaseAdapter{ 
    String []VISIT,DATE,URL; 
    int []ID; 
    Context c; 
    private LayoutInflater mInflater; 

    static class ViewHolder { 
     TextView url; 
     TextView visit; 
     TextView date; 
     ImageView imgIcon; 
    } 

    public BrowserLogListAdapter(Context context,int[]id, String[]visit, String[]date,String []url){ 
     c=context; 
     mInflater = LayoutInflater.from(context); 
     ID = id; 
     VISIT = visit; 
     DATE = date; 
     URL = url; 
    } 

    public int getCount() { 
     // TODO Auto-generated method stub 
     return ID.length; 
    } 

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

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

    public View getView(int position, View convertView, ViewGroup parent) { 
     // TODO Auto-generated method stub 
     ViewHolder holder; 
     if (convertView == null) 
     { 
      convertView = mInflater.inflate(R.layout.browser_log_list_item, null); 
      holder = new ViewHolder(); 
     // holder.visit = (TextView) convertView.findViewById(R.id.txt_visit); 
      holder.date = (TextView)convertView.findViewById(R.id.txt_time); 
      holder.url = (TextView)convertView.findViewById(R.id.txtURL); 
      convertView.setTag(holder); 
     } 
     else 
      holder = (ViewHolder) convertView.getTag(); 
     Logger.debug(VISIT[position]); 
     //holder.visit.setText(c.getString(R.string.txt_total_visit)+": "+ VISIT[position]); 
     String text = "<a href='"+URL[position]+"'>"+URL[position]+"</a>"; 
     Logger.debug("text:"+text); 
     holder.date.setText(DATE[position]); 
     holder.url.setText(Html.fromHtml(text)); 
     holder.url.setMovementMethod(LinkMovementMethod.getInstance()); 

     return convertView; 
    } 
} 

和活动，我呼吁该适配器一样，

lvlView.setAdapter(new BrowserLogListAdapter(getApplicationContext(), id, visit, time, url)); 

所以当我试图点击列表视图中的URL链接，它让我看到错误，如

如果我使用同样的合作德于简单的TextView URL重定向除了在自定义列表适配器它工作正常，但在列表视图它表明这个错误

Answer 1

试试这个

holder.url.setText(URL[position]); 
holder.url.setOnClickListener(new View.OnClickListener() 
{ 
@Override 
public void onClick(View v) 
{ 
    Intent i = new Intent(Intent.ACTION_VIEW,Uri.parse(URL[position])); 
startActivity(i); 
} 
});
