开发步骤：

1.告诉系统 想打开新的界面并且想获取新界面的返回值

2. 将数据返回 并关闭自己

3. 实现onActivityResult()  获取响应值

MainActivity.java

package com.li.pageTransfer;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.view.View;import android.widget.ImageView;import android.widget.TextView;public class MainActivity extends Activity {	private ImageView mHandImage;	private TextView mSex;	@Override	protected void onCreate(Bundle savedInstanceState) {		super.onCreate(savedInstanceState);		setContentView(R.layout.activity_main);		mHandImage=(ImageView)findViewById(R.id.handImage);		mSex=(TextView)findViewById(R.id.setTextView);	}	//点击跟换头像	public void clickHandImage(View v){		Intent intent = new Intent(this,MyHandImage.class);		//requestCode		startActivityForResult(intent, 1);	}	//点击选择性别	public void clickSelectSex(View v){		Intent intent = new Intent(this,SetSex.class);		startActivityForResult(intent, 2);	}	@Override	//resultCode区分哪一个页面的传来的值	protected void onActivityResult(int requestCode, int resultCode, Intent data) {		if(data!=null){			if(requestCode==1){				mHandImage.setImageResource(data.getIntExtra("image", 0));			}			if(requestCode==2){				mSex.setText(data.getStringExtra("sex"));			}		}	}	}
