上述布局代码使用到了控件ProgressBar（进度条），它是用来显示 小宝宝的生命值、攻击值和敏捷度的。
ProgressBar通经常使用于訪问网络展示Loading对话框以及下载文件时显示的进度。

import java.io.Serializable;
//实现序列化方便传递数据
public class ItemInfo implements Serializable{
private String name;
private int acctack;
private int life;
private int speed;
public ItemInfo(String name, int acctack, int life, int speed) {
this.name = name;
this.acctack = acctack;
this.life = life;
this.speed = speed;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAcctack() {
return acctack;
}
public void setAcctack(int acctack) {
this.acctack = acctack;
}
public int getLife() {
return life;
}
public void setLife(int life) {

public void setSpeed(int speed) {

}
public String toString() {
return " [name=" + name + ", acctack=" + acctack + ", life=" + life + ", speed=" + speed + "]";
}
}须要注意的是，Intent除了传递基本类型之外。仅仅能传递Serializable或Parcelable类型的数据，为了方便数据传递，在这里让ItemInfo类实现Serializable接口。
package select.itcast.cn.huichuan;
/**

*/
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.TextView;
public class ShopActivity extends Activity implements OnClickListener {
private ItemInfo itemInfo;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_shop);
itemInfo = new ItemInfo("金剑", 100, 20, 20);
findViewById(R.id.rl).setOnClickListener(this);
TextView mLifeTV = (TextView) findViewById(R.id.tv_life);
TextView mNameTV = (TextView) findViewById(R.id.tv_name);
TextView mSpeedTV = (TextView) findViewById(R.id.tv_speed);
TextView mAttackTV = (TextView) findViewById(R.id.tv_attack);
// TextView显示字符串,这里传入int值编译不会报错,执行会出错
mLifeTV.setText("生命值+" + itemInfo.getLife());
mNameTV.setText(itemInfo.getName() + "");
mSpeedTV.setText("敏捷度+" + itemInfo.getSpeed());
mAttackTV.setText("攻击力+" + itemInfo.getAcctack());
}
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch (v.getId()) {
case R.id.rl:
Intent intent = new Intent();
intent.putExtra("equipment", itemInfo);
setResult(1, intent);
finish();
break;
}
}
}
上述代码中的重点代码是后几行，从这段代码中能够看出。使用setResult（）方法跳转Activity不须要指定要跳转的Activity。setReult（）方法的作用是让当前Activity返回到它的调用者，在这里能够理解为让ShopActivity返回到MainActivity。
