这里面涉及两个知识点——超链接和跳转。以下进行逐一解说:
1.实现超链接:
1.1形成超链接文本
public static SpannableString getUserlink(String userName,
String userId) {
SpannableString ss = new SpannableString(userName);
URLSpan urlSpan = new URLSpan("gch://" + userId);
ss.setSpan(urlSpan, 0, ss.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
return ss;
}
1.2将其加入到TextView上面:
mTVText.setText(getUserlink("guchuanhang", "2010111180"));
1.3给该TextView设置权限
mTVText.setMovementMethod(LinkMovementMethod.getInstance());
注意:这里默认生成的超链接是有下划线&&字体颜色是蓝色的,假设要删除下划线||改动超链接的颜色。能够使用UrlSpanNoUnderline .java代替URLSpan,其代码例如以下:
package com.scott.crash;
import android.graphics.Color;
import android.os.Bundle;
import android.support.v4.content.res.ResourcesCompat;
import android.support.v7.app.AppCompatActivity;
import android.text.TextPaint;
import android.text.style.URLSpan;
import android.widget.TextView;
public class UrlSpanNoUnderline extends URLSpan {
int greenColor=0;
public UrlSpanNoUnderline(String p_Url) {
super(p_Url);
greenColor= Color.parseColor("#00ff00");
}
public void updateDrawState(TextPaint p_DrawState) {
super.updateDrawState(p_DrawState);
p_DrawState.setUnderlineText(false);
p_DrawState.setColor(greenColor);
}
}

以下是加入超链接页面的完整代码:
package com.example.androidtest;
import android.app.Activity;
import android.os.Bundle;
import android.text.Spannable;
import android.text.SpannableString;
import android.text.SpannableStringBuilder;
import android.text.method.LinkMovementMethod;
import android.text.style.URLSpan;
import android.widget.TextView;
public class FirstActivity extends Activity {
TextView mTVText;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mTVText = new TextView(this);
setContentView(mTVText);
mTVText.setMovementMethod(LinkMovementMethod.getInstance());
mTVText.setText(getUserlink("guchuanhang", "2010111180"));
// mTVText.setText(getZanSequence());
}
public static SpannableString getUserlink(String userName,
String userId) {
SpannableString ss = new SpannableString(userName);
URLSpan urlSpan = new URLSpan("gch://" + userId);
ss.setSpan(urlSpan, 0, ss.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
return ss;
}
}
2.实现跳转:
2.1给目标页面加入对应标志(在manifest中声明。相似于“声称,我是维修电脑的。有电脑问题的请找我”)。
在目标Activity中加入怎样intent
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<data android:scheme="gch" >
</data>
</intent-filter>
在Android中的intent-filter中。声明,处理“gch://?
?
?”的url。
2.2在目标Activity中解析url。获取想要的数据:
import android.app.Activity;
import android.os.Bundle;
import android.text.Spannable;
import android.text.SpannableString;
import android.text.style.URLSpan;
import android.widget.Button;
import android.widget.TextView;
public class SecondActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TextView show = new TextView(this);
setContentView(show);
/**
* 因为gch://有6个字符组成,所以。截取6位之后的字符串就可以
*/
String urlString = getIntent().getDataString().substring(6);
show.setText(urlString);
}
}
