在activity之间传递intent
step 1. 创建一个新的activity

step 2. 向AndroidManifest.xml的application中添加一个activity

step 4. 实现第一个activity
package com.example.michael;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.widget.TextView;public class Android_SecondActivity extends Activity {private TextView myTextView = null;/** Called when the activity is first created. */    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.second);        Intent intent = getIntent();        String value = intent.getStringExtra("key1");        myTextView = (TextView) findViewById(R.id.myView);        myTextView.setText(value);    }}
