</pre>要求：在firstactivity活动中有一串字符串，传递到secondactivity中<p>firstactivity中button1中的代码、</p><p></p><pre name="code" class="java">String data = "hello secondactivity";Intent intent = new Intent(FirstActivity.this,SecondActivity.class);intent.putExtra(extea_data, data);startActivity(intent);

secondactivity将传递的数据取出来，并打印出来

package com.example.activitytest;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.util.Log;import android.view.Window;public class SecondActivity extends Activity{@Overrideprotected void onCreate(Bundle savedInstanceState) {// TODO Auto-generated method stubsuper.onCreate(savedInstanceState);requestWindowFeature(Window.FEATURE_NO_TITLE);setContentView(R.layout.second);Intent intent = getIntent();String data =intent.getStringExtra("extra_data");Log.d("SecondActivity", data);}}
