Android开发实现TextView显示丰富的文本
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>
