TextView單擊連結彈出Activity

ui設計

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

    <TextView
        android:id="@+id/textview"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:textSize="20sp" />

</LinearLayout>
           

建立Activity1

package com.android.mytextview;

import android.app.Activity;
import android.os.Bundle;

public class Activity1 extends Activity {

	public Activity1() {
		// TODO Auto-generated constructor stub
	}

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		super.onCreate(savedInstanceState);
		setTitle("Activity1");
	}
}
           

建立Activity2

package com.android.mytextview;

import android.app.Activity;
import android.os.Bundle;

public class Activity2 extends Activity {

	public Activity2() {
		// TODO Auto-generated constructor stub
	}

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		super.onCreate(savedInstanceState);
		setTitle("Activity2");
	}
}
           

AndroidMainfest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.android.mytextview"
    android:versionCode="1"
    android:versionName="1.0" >

    <application
        android:icon="@drawable/icon"
        android:label="@string/app_name" >
        <activity
            android:name=".Main"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:name=".Activity1" >
        </activity>
        <activity android:name=".Activity2" >
        </activity>
    </application>

    <uses-sdk android:minSdkVersion="8" />

</manifest>
           

Main主程式

package com.android.mytextview;

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

public class Main extends Activity {
	/** Called when the activity is first created. */
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		TextView textView = (TextView) this.findViewById(R.id.textview);
		TextView textView2 = (TextView) this.findViewById(R.id.textview2);
		String text1 = "name:dashu";
		String text2 = "name:meizi";
		// 主要是用來拆分字元串
		SpannableString spannableString1 = new SpannableString(text1);
		SpannableString spannableString2 = new SpannableString(text2);
		spannableString1.setSpan(new ClickableSpan() {

			@Override
			public void onClick(View widget) {
				// 點選name跳轉到Activity1
				Intent intent = new Intent(Main.this, Activity1.class);
				startActivity(intent);
			}
		}, 0, 4, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
		spannableString2.setSpan(new ClickableSpan() {
			@Override
			public void onClick(View widget) {
				// 點選meizi跳轉到Activity2
				Intent intent = new Intent(Main.this, Activity2.class);
				startActivity(intent);
			}
		}, 5, text1.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
		textView.append(spannableString1);
		textView.append(spannableString2);
		textView.setMovementMethod(LinkMovementMethod.getInstance());
	}
}
           

定義兩個SpannableString對象拆分字元串，并響應單擊跳轉，實作了一個TextView控件根據不同字段響應不同的點選事件.
