1.在layout中创建程序（activity.main）
用来编写主界面
代码如下：
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/activity_main" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context="com.example.bz0209.xzx0734.MainActivity">
<TextView android:id="@+id/biao" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerInParent="true" android:text="快给我买装备"/> <TableLayout android:id="@+id/sheng" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_gravity="center" android:layout_marginBottom="20dp" android:layout_below="@id/biao" > <TableRow android:layout_width="match_parent" android:layout_height="wrap_content"> <TextView android:id="@+id/shengming" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="生命值:" /> <ProgressBar android:id="@+id/progressBar1" style="?android:attr/progressBarStyleHorizontal" android:layout_height="wrap_content" android:layout_width="match_parent" android:layout_gravity="center" android:layout_weight="9" /> <TextView android:id="@+id/tv_life_progress" android:layout_height="wrap_content" android:layout_weight="1" android:text="0" android:textColor="#000000" /> </TableRow> <TableRow android:layout_width="match_parent" android:layout_height="wrap_content"> <TextView android:id="@+id/gongji" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="攻击:" /> <ProgressBar android:id="@+id/progressBar2" style="?android:attr/progressBarStyleHorizontal" android:layout_height="wrap_content" android:layout_width="match_parent" android:layout_gravity="center" android:layout_weight="9" /> <TextView android:id="@+id/tv_attack_progress" android:layout_height="wrap_content" android:layout_weight="1" android:text="0" android:textColor="#000000" /> </TableRow> <TableRow android:layout_width="match_parent" android:layout_height="wrap_content"> <TextView android:id="@+id/minjie" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="敏捷:" /> <ProgressBar android:id="@+id/progressBar3" style="?android:attr/progressBarStyleHorizontal" android:layout_height="wrap_content" android:layout_width="match_parent" android:layout_gravity="center" android:layout_weight="9" /> <TextView android:id="@+id/tv_speed_progress" android:layout_height="wrap_content" android:layout_weight="1" android:text="0" android:textColor="#000000" /> </TableRow>
</TableLayout> <RelativeLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginLeft="50dp" android:layout_marginRight="50dp" android:layout_marginTop="20dp">
</RelativeLayout> <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="买装备" android:onClick="click" android:layout_below="@id/sheng" android:layout_centerHorizontal="true"/> </RelativeLayout>
2.创建装备选择的界面
<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/activity_shop2" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context="com.example.bz0209.xzx0734.ShopActivity">
<TextView android:id="@+id/tv_name" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="商品名称" android:layout_marginLeft="90dp"
/> <LinearLayout android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerHorizontal="true" android:orientation="vertical" > <TextView android:id="@+id/tv_life" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="生命值" /> <TextView android:id="@+id/tv_attack" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="攻击"/> <TextView android:id="@+id/tv_speed" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="速度"/> </LinearLayout> </RelativeLayout>
3.创建一个类用于封装信息
package com.example.bz0209.xzx0734.cn.itcast.domain;
import java.io.Serializable;
/** * Created by Administrator on 2017/4/1. */
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+"]"; } }
4.创建shopActivity
package com.example.bz0209.xzx0734;
import android.app.Activity; import android.content.Intent; import android.os.Bundle; import android.view.View; import android.widget.TextView; import com.example.bz0209.xzx0734.cn.itcast.domain.ItemInfo;
/** * Created by Administrator on 2017/3/30. */
public class ShopActivity extends Activity implements View.OnClickListener { private ItemInfo itemInfo;
protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_shop2); itemInfo = new ItemInfo("金剑", 100, 20, 20); findViewById(R.id.activity_shop2).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()); }
public void onClick(View v) { switch (v.getId()) { case R.id.activity_shop2: Intent intent = new Intent(); intent.putExtra("equipment", itemInfo); setResult(1, intent); finish(); break; } } }
5.编写交互代码MainAcitvity
package com.example.bz0209.xzx0734;
import android.app.Activity; import android.content.Intent; import android.os.Bundle; import android.view.View; import android.widget.ProgressBar; import android.widget.TextView;
import com.example.bz0209.xzx0734.R; import com.example.bz0209.xzx0734.ShopActivity; import com.example.bz0209.xzx0734.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;
@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(); }
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); }
@Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); super.onActivityResult(requestCode, resultCode, data); if (data != null) { if (resultCode == 1) { if (requestCode == 1) { ItemInfo info = (ItemInfo) data.getSerializableExtra("equipment"); updataProgress(info); } } }
}
private void updataProgress(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() + ""); }
}
运行程序后选择买装备后显示信息
点击物品后属性变化
