android TextView如何显示html元素控件

 

    在android中，用textview显示丰富的文本，也可以嵌入html元素控件。

一、MainActivity类的代码

package com.study.android_textview;

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);
        
        //加添一段html
        String html = "<font color='red'>I love android</font><br>";
        html += "<font color='#0000ff'><big><i>I love android</i></big></font><p>";
        html += "<big><a href='http://www.baidu.com'>百度</a></big>";
        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：+86 010-89487369";
        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;
    }
    
}

二、strings.xml

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

    <string name="app_name">如何显示html的元素控件</string>
    <string name="action_settings">Settings</string>
    <string name="hello_world">Hello world!</string>
    <color name="green">#00ff00</color>
    <string name="link_text"><a href="tel:18651032915">打电话</a> </string>

    
</resources>

三、main.xml

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

    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:id="@+id/textview1"
        android:padding="20sp"
         />
     <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:id="@+id/textview2"
        android:padding="20sp"
        android:autoLink="all"
        android:textSize="20sp"
        android:text="@string/link_text"
         />

</LinearLayout>

四、显示效果
