Question

我正在尝试在listview中显示网址，当用户点击网址时，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;
    }
}

并且在活动中我称这个适配器为

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

因此当我尝试点击列表视图中的url链接时，它会显示错误，如

如果我在简单文本视图中使用相同的代码进行网址重定向，而不是自定义列表适配器，它可以正常工作，但在列表视图中显示此错误

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);
}
});

Linkview在listview android中
