【Android开发日记】TextView超链接启动Activity，取消下划线自定义颜色

需求如题：

代码1：main.xml

    android:layout_
    android:layout_
    android:orientation="vertical" >

            android:id="@+id/tv123"
        android:layout_
        android:layout_
        android:layout_marginTop="40dip"
        android:autoLink="all"
        android:text="123" />

package com.test.link;

import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.graphics.Color;
import android.os.Bundle;
import android.os.Parcel;
import android.text.ParcelableSpan;
import android.text.SpannableString;
import android.text.Spanned;
import android.text.TextPaint;
import android.text.method.LinkMovementMethod;
import android.text.style.ClickableSpan;
import android.view.View;
import android.widget.TextView;

public class TestLinkActivity extends Activity {
private TextView tv;

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

setContentView(R.layout.main);
TextView view6 = (TextView) findViewById( R.id.tv123); 
    SpannableString text6 = new SpannableString("@jesseblack:letters is ...");  
    Intent intent = new Intent(this, TestActivity2.class);  
    text6.setSpan(new IntentSpan(intent), 0, 11, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);  
    view6.setText( text6 );  
    view6.setMovementMethod(LinkMovementMethod.getInstance());  


}

public class IntentSpan extends ClickableSpan implements ParcelableSpan {  
    private Intent mIntent;  
      
    public IntentSpan(Intent toActivity) {  
        mIntent = toActivity;  
    }  
      
    @Override
    public void updateDrawState(TextPaint ds) {
        ds.setColor(Color.parseColor("#00BFFF"));
        ds.setUnderlineText(false); 
    }
    
    @Override  
    public void onClick(View sourceView) {  
        Context cOntext= sourceView.getContext();  
        context.startActivity( mIntent );  
    }  
      
    
    public int getSpanTypeId() {  
        return 100;  
    }  
      
     
    public int describeContents() {  
        return 0;  
    }  
      
    @Override  
    public void writeToParcel(Parcel dest, int flag) {  
        // don't write to parcel  
    }  
      
    public Intent getIntent() {  
        return mIntent;  
    }  
}  

}

 取消超链接下划线 以及超链接部分文字颜色：

@Override
        public void updateDrawState(TextPaint ds) {
            ds.setColor(Color.parseColor("#00BFFF"));
            ds.setUnderlineText(false);
        }
