本文实例讲述了Android开发实现TextView显示丰富的文本的方法。分享给大家供大家参考，具体如下：
如图，显示html的元素控件，点击连接实现上网，发email，拨号
实现源码如下：
MainActivity.java
package com.example.textview2;
import android.os.Bundle;
import android.app.Activity;
import android.text.Html;
import android.text.method.LinkMovementMethod;
import android.view.Menu;
import android.widget.TextView;
public class MainActivity extends Activity {
private TextView textView1, textView2;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textView1 = (TextView) this.findViewById(R.id.textview1);
textView2 = (TextView) this.findViewById(R.id.textview2);
// 添加一段html的标志
String html = "<font color='red'></font><br><br><br>";
html += "<font color='#0000ff'><big><i></i></big></font><p>";
html += "<big><a href='http://www.baidu.com'>百度</a></big><br>";
CharSequence charSequence = Html.fromHtml(html);
textView1.setText(charSequence);
textView1.setMovementMethod(LinkMovementMethod.getInstance());// 点击的时候产生超链接
String text = "我的URL：http://www.sina.com\n";
text += "我的email：abcd@126.com\n";
text += "我的电话：+ 86 010-89487389";
textView2.setText(text);
textView2.setMovementMethod(LinkMovementMethod.getInstance());
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
strings.xml
<?xml version="1.0" encoding="utf-8"?> <resources> <string name="action_settings">Settings</string> <string name="hello_world">Hello world!</string> <string name="app_name">如何显示html的元素控件</string> <color name="green">#00FF00</color> <string name="link_text"><a href="tel:13693207964">打电话</a></string> </resources>
activity_main.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<TextView android:layout_width="fill_parent"
android:layout_height="wrap_content" android:id="@+id/textview1"
android:padding="20sp" />
<TextView
android:id="@+id/textview2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:autoLink="all"
android:padding="20sp"
android:text="@string/link_text"
android:textSize="20sp" />
</RelativeLayout>
希望本文所述对大家Android程序设计有所帮助。
