TextView

1.用TextView显示url，邮箱，电话号码

package com.example.android_textview01;

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;
	private TextView textView2;
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		textView1=(TextView) findViewById(R.id.textView1);
		textView2=(TextView) findViewById(R.id.textView2);
		String html="<font color='red'><h3>I love android<h3></font><br>";
		html+="<font color='#0000ff'<big><i><h2>I love android<i><h2><big></font><p>";
		html+="<big><a href='www.baidu.com'></a></big>";
		CharSequence charS=Html.fromHtml(html);
		textView1.setText(charS);
		textView1.setMovementMethod(LinkMovementMethod.getInstance());
		
		String text="我的url：www.sina.cn\n";
		text+="email:43232@qq.com \n";
		text+="tel:15538372152\n";
		text+="我的姓名：刘明";
		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;
	}

}

2.在TextView中显示图片表情

package com.example.android_textview02;

import java.lang.reflect.Field;

import android.os.Bundle;
import android.app.Activity;
import android.graphics.Color;
import android.graphics.drawable.Drawable;
import android.text.Html;
import android.text.Html.ImageGetter;
import android.text.method.LinkMovementMethod;
import android.view.Menu;
import android.widget.TextView;

public class MainActivity extends Activity {

	/**
	 * 通过反射取得图片id
	 * @param name
	 * @return
	 */
	public static int getResourceId(String name){
		try {
			Field field=R.drawable.class.getField(name);
			return Integer.parseInt(field.get(null).toString());
		} catch (Exception e) {
			// TODO: handle exception
		}
		return 0;
	}
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		TextView textView=(TextView) findViewById(R.id.textView);
		textView.setBackgroundColor(Color.WHITE);
		textView.setTextColor(Color.BLACK);
		textView.setTextSize(20);
		String html="图片1<img src='pic1'/>图片2<img src='pic2'/>图片3<img src='pic3'/>";
		html+="图片4<a href='http://www.baidu.com'><img src='pic4'/></a>";
		CharSequence charSequence=Html.fromHtml(html, new ImageGetter() {
			
			public Drawable getDrawable(String source) {
				// TODO Auto-generated method stub
				Drawable drawable=getResources().getDrawable(getResourceId(source));
				if(source.equals("pic3")){
					drawable.setBounds(0, 0, drawable.getIntrinsicWidth()/2, drawable.getIntrinsicHeight()/2);
					
				}
				else{
					drawable.setBounds(0, 0, drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight());
				}
				return drawable;
			}
		}, null);
		textView.setText(charSequence);
		textView.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;
	}

}

3.用TextView实现activity的跳转

package com.example.android_textview03;

import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.text.Spannable;
import android.text.SpannableString;
import android.text.method.LinkMovementMethod;
import android.text.style.ClickableSpan;
import android.view.Menu;
import android.view.View;
import android.widget.TextView;

public class MainActivity extends Activity {

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		TextView textView1 = (TextView) findViewById(R.id.textView1);
		TextView textView2 = (TextView) findViewById(R.id.textView2);
		String text1 = "Activity1";
		String text2 = "Activity2";
		SpannableString spannableString1 = new SpannableString(text1);
		SpannableString spannableString2 = new SpannableString(text2);
		spannableString1.setSpan(new ClickableSpan() {

			@Override
			public void onClick(View arg0) {
				// TODO Auto-generated method stub
				Intent intent1 = new Intent(MainActivity.this, Activity1.class);
				startActivity(intent1);

			}
		}, 0, text1.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
		spannableString2.setSpan(new ClickableSpan() {

			@Override
			public void onClick(View arg0) {
				// TODO Auto-generated method stub
				Intent intent2 = new Intent(MainActivity.this, Activity2.class);
				startActivity(intent2);

			}
		}, 0, text1.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
		textView1.setText(spannableString1);
		textView2.setText(spannableString2);
		textView1.setMovementMethod(LinkMovementMethod.getInstance());
		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;
	}

}

4.用TextView实现跑马灯效果，并可以点击超链接（超链接不行啊。。。。）

private TextView textView;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        //实现方式一：
//      String text="北京青年报记者体验下载“96106易达打车”、“96106移步叫车”、“96106嘀嘀打车”和";
//      textView=(TextView)findViewById(R.id.tv);
//      textView.setText(text);

        //实现方式二：
        //添加HTML标签<a></a>可以设置超链接
        String text="北京青年报记者体验下载“96106易达打车“<a href='http://www.baidu.com'>“96106移步叫车”</a>、" +
                "“96106嘀嘀打车”和";
        CharSequence charSequence=Html.fromHtml(text);
        textView=(TextView)findViewById(R.id.tv);
        textView.setText(charSequence);
        textView.setMovementMethod(LinkMovementMethod.getInstance());
    }
布局文件：
<TextView
        android:id="@+id/tv"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:singleLine="true"
        android:ellipsize="marquee"
        android:marqueeRepeatLimit="marquee_forever"
        android:focusable="true"
        android:focusableInTouchMode="true"
        android:background="#FFFFFF"
        android:textColor="#000"
        android:textSize="20dp"
        android:layout_margin="10dp"
         />
        <!-- 属性解析
        singleLine          要实现跑马灯则TextView单行显示
        ellipsize               显示的效果，有四个值
                |——start        省略号在开头
                |——middle  省略号在中间
                |——end      省略号在结尾
                |——marquee 跑马灯显示
        marqueeRepeatLimit          跑马灯重复的限制
        focusable           是否触发焦点，即TextView能否点击
        focusableInTouchMode        设置焦点的联系方式，在模拟器中没有这个属性则没有跑马灯效果。
