本文实例讲述了Android编程开发之TextView单击链接弹出Activity的方法。分享给大家供大家参考，具体如下：

话不多说直接上码：

核心源码：

package com.example.textview4;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 MainActivity extends Activity {  @Override  protected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.activity_main);    TextView tv1 = (TextView) findViewById(R.id.textView1);    TextView tv2 = (TextView) findViewById(R.id.textView2);    String text1 = "显示第一个activity";    String text2 = "显示第二个activity";    // 将text进行拆分    SpannableString ss1 = new SpannableString(text1);    SpannableString ss2 = new SpannableString(text2);    ss1.setSpan( new ClickableSpan() {      @Override      public void onClick(View widget) {        Intent intent = new Intent(MainActivity.this, FirstActivity.class);        startActivity(intent);      }    }, 0, text1.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);    ss2.setSpan(new ClickableSpan() {      @Override      public void onClick(View widget) {        Intent intent = new Intent(MainActivity.this, SecondActivity.class);        startActivity(intent);      }    }, 0, text2.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);    tv1.setText(ss1);    tv2.setText(ss2);    tv1.setMovementMethod(LinkMovementMethod.getInstance());    tv2.setMovementMethod(LinkMovementMethod.getInstance());  }}

运行效果截图如下：
