Android之装备选择案例

1.创建程序界面

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

xmlns:tools="http://schemas.android.com/tools"

android:layout_width="match_parent"

android:layout_height="match_parent"

tools:context=".Main"

android:orientation="vertical"

<TableLayout

android:layout_width="fill_parent"

android:layout_height="wrap_content"

android:layout_gravity="center"

android:layout_marginBottom="20dp">

<TableRow

android:layout_width="fill_parent"

android:layout_height="wrap_content">

<TextView

android:layout_width="0dip"

android:layout_height="wrap_content"

android:layout_weight="1"

android:text="生命值："

android:textColor="@android:color/black"

android:textSize="14sp"/>

<ProgressBar

android:id="@+id/progressBar1"

</TableRow>

<TableRow

android:layout_width="fill_parent"

android:layout_height="wrap_content"

android:layout_marginTop="5dp">

<TextView

android:layout_width="0dip"

android:layout_height="wrap_content"

android:layout_weight="1"

android:text="攻击力:"

android:textColor="@android:color/black"

android:gravity="center"

android:textColor="#000000" />

</TableRow>

<TableRow

android:layout_width="fill_parent"

android:layout_height="wrap_content"

android:layout_marginTop="5dp">

<TextView

android:layout_width="0dip"

android:layout_height="wrap_content"

android:layout_weight="1"

android:text="敏 捷:"

android:textColor="@android:color/black"

android:textSize="14sp" />

</TableRow>

</TableLayout>

<RelativeLayout

android:layout_width="match_parent"

android:layout_height="wrap_content" >

<Button

android:id="@+id/btn_baby"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_alignParentRight="true"

android:layout_alignParentTop="true"

android:drawablePadding="3dp"

android:drawableRight="@android:drawable/ic_menu_add"

android:onClick="click2"

android:text="小宝宝购买装备"

android:textSize="14sp" />

</RelativeLayout>

</LinearLayout>

2.创建装备界面

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:id="@+id/rl"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:orientation="vertical">

<View

android:layout_width="30dp"

android:layout_height="30dp"

android:background="@android:drawable/ic_menu_info_details"

android:layout_centerVertical="true"

android:layout_alignParentLeft="true"

/>

<TextView

android:id="@+id/tv_name"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_centerVertical="true"

android:layout_marginLeft="60dp"

android:text="商品名称"/>

<LinearLayout

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_centerInParent="true"

android:orientation="vertical">

<TextView

android:id="@+id/tv_life"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:textSize="13sp"

android:text="生命值" />

<TextView

android:id="@+id/tv_attack"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:textSize="13sp"

android:text="攻击力"

android:layout_marginTop="5dp"/>

<TextView

android:id="@+id/tv_speed"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:textSize="13sp"

android:text="敏 捷"

android:layout_marginTop="5dp"/>

</LinearLayout>

</RelativeLayout>

3.创建Info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 + "]";

}

}



4.创建购买装备程序界面

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;

}

}

}

5.界面交互程序

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);

}

}
