购买装备

activity_main.xml 布局文件中的代码为：
































其界面效果如下:



创建装备界面activity_shop.xml,来展示装备，其布局文件代码如下：









其界面效果如下:



创建ItemInfo类
package cn.itcast.domain;
import java.io.Serializable;
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) {
this.life = life;
}
public int getSpeed() {
return speed;
}
public void setSpeed(int speed) {
this.speed = speed;
}
public String toString() {
return " [name=" + name + ", acctack=" + acctack + ", life=" + life
+ ", speed=" + speed + "]";
}
}


创建ShopActivity,用来展示装备信息，当单击ShopActivity的装备时，会调回MainActivity，并将装备信息回传给MainActivity。代码如下:
package cn.itcast.select;
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;import cn.itcast.domain.ItemInfo;
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);
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;
}
}
}

界面交互代码：
package cn.itcast.select;
import java.util.ArrayList;import java.util.List;
import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.view.View;import android.widget.ListView;import android.widget.ProgressBar;import android.widget.TextView;import android.widget.Toast;import cn.itcast.domain.ItemInfo;
public class MainActivity extends Activity {
private ProgressBar mProgressBar1;
private ProgressBar mProgressBar2;
private ProgressBar mProgressBar3;
private TextView mLifeTV;
private TextView mAttackTV;
private TextView mSpeedTV;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mLifeTV = (TextView) findViewById(R.id.tv_life_progress);
mAttackTV = (TextView) findViewById(R.id.tv_attack_progress);
mSpeedTV = (TextView) findViewById(R.id.tv_speed_progress);
initProgress(); }

private void initProgress() {
mProgressBar1 = (ProgressBar) findViewById(R.id.progressBar1);
mProgressBar2 = (ProgressBar) findViewById(R.id.progressBar2);
mProgressBar3 = (ProgressBar) findViewById(R.id.progressBar3);
mProgressBar1.setMax(1000); mProgressBar2.setMax(1000);
mProgressBar3.setMax(1000);
}

public void click(View view) {
Intent intent = new Intent(this, ShopActivity.class);
startActivityForResult(intent, 1); }

public void click2(View view) {
Intent intent = new Intent(this, ShopActivity.class);
startActivityForResult(intent, 1);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (data != null) {
if (resultCode == 1) {
if (requestCode == 1) {
ItemInfo info= (ItemInfo) data.getSerializableExtra("equipment");
updateProgress(info);
}
}
}
}
private void updateProgress(ItemInfo info) {
int progress1 = mProgressBar1.getProgress();
int progress2 = mProgressBar2.getProgress();
int progress3 = mProgressBar3.getProgress();
mProgressBar1.setProgress(progress1+info.getLife());
mProgressBar2.setProgress(progress2+info.getAcctack());
mProgressBar3.setProgress(progress3+info.getSpeed());
mLifeTV.setText(mProgressBar1.getProgress()+"");
mAttackTV.setText(mProgressBar2.getProgress()+"");
mSpeedTV.setText(mProgressBar3.getProgress()+"");
}
}
