【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

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >

<TextView
android:id="@+id/tv123"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="40dip"
android:autoLink="all"
android:text="123" />

</LinearLayout>

代码2：mainactivity.java

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;
}
}

}

说明：

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);

}
