Android开发（15）-TextView显示丰富的文本

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 = "";
        html += "";
        html += "百度";
        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：[email protected]\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;
    }

}
