android 数据回传（装备选择）

android 数据回传（装备选择）
一、页面布局‘0’
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通常用于访问网络展示Loading对话框以及下载文件时显示的进度。
ProgressBar几个常用方法属性
1.style属性
2.setMax（）：进度条最大值
3.setProgress（）：设置当前进度

4.getProgress（）：获取当前进度

页面布局：

 

创建装备界面：

 

 

创建ItemInfo类:\

 

 

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:

 

 

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,运行会出错
    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;
    }
    }
    }

编写界面交互代码:

 

 

package select.itcast.cn.huichuan;

    import android.app.Activity;
    import android.content.Intent;
    import android.os.Bundle;
    import android.view.Menu;
    import android.view.MenuItem;
    import android.view.View;
    import android.widget.ProgressBar;
    import android.widget.TextView;


    public class Main extends Activity {

    private ProgressBar mProgressBar1;
    private ProgressBar mProgressBar2;
    private ProgressBar mProgressBar3;
    private TextView mLifeTV;
    private TextView mAttackTV;
    private TextView mSpeedTV;

    @Override
    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();                    //初始化进度条
    }

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

    // 开启新的activity并且想获取他的返回值
    public void click(View view) {
    Intent intent = new Intent(this, ShopActivity.class);
    startActivityForResult(intent, 1); // 返回请求结果,请求码为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) {
    // 判断结果码是否等于1,等于1为主人添加装备,等于2为宝宝添加装备
    if (resultCode == 1) {
    if (requestCode == 1) {
    ItemInfo info= (ItemInfo) data.getSerializableExtra("equipment");
    //更新ProgressBar的值
    updateProgress(info);
    }
    }
    }
    }
    //更新ProgressBar的值
    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() + "");
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_main, menu);
    return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    //noinspection SimplifiableIfStatement
    if (id == R.id.action_settings) {
    return true;
    }

    return super.onOptionsItemSelected(item);
    }
    }
