在一个Activity里面的TextView上面添加网页链接,启动后到另一个Activity里面!

可以添加很多的属性,样式或者是什么的,目前要完成的功能是 点击TextView里面的某个文字链接,进入另外一个Activity里面!
例如你可以做微博里面的 @XXX; 点击后进入他的个人主页!

下面都是Activity:

package wq.gdky005;

import java.util.ArrayList;

import android.R.color;
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.graphics.Color;
import android.os.Bundle;
import android.text.Html;
import android.text.Spannable;
import android.text.SpannableStringBuilder;
import android.text.method.LinkMovementMethod;
import android.text.style.ClickableSpan;
import android.text.style.URLSpan;
import android.view.View;
import android.widget.TextView;
import android.widget.Toast;

public class AbcActivity extends Activity {
    private TextView tv;
    private static Context ctx;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        tv = new TextView(this);
        tv.setClickable(false);
        ctx = this;

        String htmlLinkText = "";

        htmlLinkText = "aaaaaaaaaa"
                + "<a style="color:red;" href="我是超链接……">@超链接点击事件;</a>" +
                "     <a style="color:red;" href="我是超链接2……">@超链接点击事件;</a>"
                + "aaaaaaaaaaaaaaaa";
        // 文字的样式(style)被覆盖,不能改变……

        tv.setText(Html.fromHtml(htmlLinkText));
        tv.setMovementMethod(LinkMovementMethod.getInstance());
        CharSequence text = tv.getText();
        if (text instanceof Spannable) {
            int end = text.length();
            Spannable sp = (Spannable) tv.getText();
            URLSpan[] urls = sp.getSpans(0, end, URLSpan.class);
            SpannableStringBuilder style = new SpannableStringBuilder(text);
            style.clearSpans();// should clear old spans
            for (URLSpan url : urls) {
                MyURLSpan myURLSpan = new MyURLSpan(url.getURL());
                style.setSpan(myURLSpan, sp.getSpanStart(url),
                        sp.getSpanEnd(url), Spannable.SPAN_EXCLUSIVE_INCLUSIVE);
            }
            tv.setText(style);
        }
        setContentView(tv);

    }

    private static class MyURLSpan extends ClickableSpan {

        private String mUrl;

        MyURLSpan(String url) {
            mUrl = url;
        }

        @Override
        public void onClick(View widget) {
            Toast.makeText(ctx, mUrl, Toast.LENGTH_LONG).show();
            widget.setBackgroundColor(Color.parseColor("#00000000"));
            
            Intent intent = new Intent(AbcActivity.ctx, AAAActivity.class);
            ctx.startActivity(intent);
            
            
        }
    }
}

这是设置文件的颜色和样式的

TextView是用来显示文本的,有时需要给TextView中的个别字设置为超链接,或者设置个别字的颜色、字体等,那就需要用到Spannable对象,可以借助Spannable对象实现以上设置

myTextView = (TextView) this.findViewById(R.id.myTextView);   
    
  //创建一个 SpannableString对象   
  SpannableString sp = new SpannableString("这句话中有百度超链接,有高亮显示,这样,或者这样,还有斜体.");   
  //设置超链接   
  sp.setSpan(new URLSpan("http://www.baidu.com"), 5, 7,   
  Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);   
  //设置高亮样式一   
  sp.setSpan(new BackgroundColorSpan(Color.RED), 17 ,19,Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);   
  //设置高亮样式二   
  sp.setSpan(new ForegroundColorSpan(Color.YELLOW),20,24,Spannable.SPAN_EXCLUSIVE_INCLUSIVE);   
  //设置斜体   
  sp.setSpan(new StyleSpan(android.graphics.Typeface.BOLD_ITALIC), 27, 29, Spannable.SPAN_EXCLUSIVE_INCLUSIVE);   
  //SpannableString对象设置给TextView   
  myTextView.setText(sp);   
  //设置TextView可点击   
  myTextView.setMovementMethod(LinkMovementMethod.getInstance());
