（四十八）Android TextView中文字通过SpannableString来设置超链接、颜色、字体等属性

1、程序结构图



2、MainActivity.java中的代码

package com.example.setlinkdemo;

import java.io.IOException;

import org.xmlpull.v1.XmlPullParserException;

import android.app.Activity;
import android.content.Intent;
import android.content.res.ColorStateList;
import android.content.res.XmlResourceParser;
import android.os.Bundle;
import android.text.Html;
import android.text.SpannableString;
import android.text.Spanned;
import android.text.method.LinkMovementMethod;
import android.text.style.ClickableSpan;
import android.text.style.TextAppearanceSpan;
import android.view.View;
import android.widget.TextView;

public class MainActivity extends Activity {
private TextView tv_content;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tv_content = (TextView) this.findViewById(R.id.tv_content);
setLink();
}

public  void setLink() {
// TODO Auto-generated method stub
// 创建一个 SpannableString对象
SpannableString sp = new SpannableString(
Html.fromHtml(getString(R.string.set_account_check)));
sp.setSpan(new ClickableSpan() {
@Override
public void onClick(View widget) {
// TODO Auto-generated method stub
startActivity(new Intent(MainActivity.this, TestActivity.class));
}
}, 11, 15, Spanned.SPAN_INCLUSIVE_EXCLUSIVE);

ColorStateList csl = null;
XmlResourceParser xpplinkcolor = getResources().getXml(
R.color.link_color);
try {
csl = ColorStateList.createFromXml(getResources(), xpplinkcolor);
} catch (XmlPullParserException e1) {
e1.printStackTrace();
} catch (IOException e2) {
e2.printStackTrace();
}

sp.setSpan(
new TextAppearanceSpan("monospace",
android.graphics.Typeface.NORMAL, (int) tv_content
.getTextSize(), csl, csl), 11, 15,
Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
tv_content.setText(sp);
// 不添加这一句,超链接不能点击
tv_content.setMovementMethod(LinkMovementMethod.getInstance());
}

}

3、TestActivity.java中的代码

package com.example.setlinkdemo;

import android.app.Activity;
import android.os.Bundle;

public class TestActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}

4、link_color.xml文件中的代码

<?xml version="1.0" encoding="utf-8"?>
<selector  xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true"
android:color="#0099cc"/> <!-- pressed -->
<item android:state_focused="true"
android:color="#0099cc"/> <!-- focused -->
<item android:color="#0099cc"/> <!-- default -->
</selector>

6、strings.xml文件中的代码

<?xml version="1.0" encoding="utf-8"?>
<resources>

<string name="app_name">SetLinkDemo</string>
<string name="hello_world">Hello world!</string>
<string name="action_settings">Settings</string>
<string name="set_account_check">继续进行意味着您已同意服务协议</string>

</resources>

7、AndroidManifest.xml文件中的代码

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.setlinkdemo"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="17" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"

<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".TestActivity" >
</activity>
</application>
</manifest>
