第一行代码系列第二章——向下一个活动传递数据

</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{
	
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		super.onCreate(savedInstanceState);
		requestWindowFeature(Window.FEATURE_NO_TITLE);
		setContentView(R.layout.second);
		Intent intent = getIntent();
		String data =intent.getStringExtra("extra_data");
		Log.d("SecondActivity", data);
	}
