1.创建程序界面

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

</LinearLayout>
2.创建装备界面
1. <?xml version="1.0" encoding="utf-8"?>
2. <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
4. android:id="@+id/rl"
5. android:layout_width="match_parent"
6. android:layout_height="wrap_content"
7. android:orientation="vertical">
8. <View
9. android:layout_width="30dp"
10. android:layout_height="30dp"
11. android:background="@android:drawable/ic_menu_info_details"
12. android:layout_centerVertical="true"
13. android:layout_alignParentLeft="true"
14. />
15. <TextView
16. android:id="@+id/tv_name"
17. android:layout_width="wrap_content"
18. android:layout_height="wrap_content"
19. android:layout_centerVertical="true"

45. android:text="敏捷"
46. android:layout_marginTop="5dp"/>
47. </LinearLayout>
48. </RelativeLayout>
49. 3.创建Info类
50. 1. public class ItemInfo implements Serializable{
  2. private String name;
  3. private int acctack;
  4. private int life;
  5. private int speed;
  6. public ItemInfo(String name, int acctack, int life, int speed) {
  7. this.name = name;
  8. this.acctack = acctack;
  9. this.life = life;
  10. this.speed = speed;
  11. }
  12. public String getName() {
  13. return name;
  14. }
  15. public void setName(String name) {
  16. this.name = name;
  17. }
  18. public int getAcctack() {
  19. return acctack;
  20. }
  21. public void setAcctack(int acctack) {
  22. this.acctack = acctack;
  23. }
  24. public int getLife() {
  25. return life;
  26. }
  27. public void setLife(int life) {
  28. this.life = life;
  29. }
  30. public int getSpeed() {
  31. return speed;
  32. }
  33. public void setSpeed(int speed) {
  34. this.speed = speed;
  35. }
  36. public String toString() {
  37. return " [name=" + name + ", acctack=" + acctack + ", life=" + life + ", speed=" + speed + "]";
  38. }
  39. }
4.创建购买装备程序界面
1. import android.app.Activity;
2. import android.content.Intent;
3. import android.os.Bundle;
4. import android.view.View;
5. import android.view.View.OnClickListener;
6. import android.widget.TextView;
9. public class ShopActivity extends Activity implements OnClickListener {
11. private ItemInfo itemInfo;
13. protected void onCreate(Bundle savedInstanceState) {
14. super.onCreate(savedInstanceState);
15. setContentView(R.layout.activity_shop);
16. itemInfo = new ItemInfo("金剑", 100, 20, 20);
17. findViewById(R.id.rl).setOnClickListener(this);
18. TextView mLifeTV = (TextView) findViewById(R.id.tv_life);
19. TextView mNameTV = (TextView) findViewById(R.id.tv_name);
20. TextView mSpeedTV = (TextView) findViewById(R.id.tv_speed);
21. TextView mAttackTV = (TextView) findViewById(R.id.tv_attack);
22. // TextView显示字符串,这里传入int值编译不会报错,运行会出错
23. mLifeTV.setText("生命值+" + itemInfo.getLife());
24. mNameTV.setText(itemInfo.getName() + "");
25. mSpeedTV.setText("敏捷度+" + itemInfo.getSpeed());
26. mAttackTV.setText("攻击力+" + itemInfo.getAcctack());
27. }
29. @Override
30. public void onClick(View v) {
31. // TODO Auto-generated method stub
32. switch (v.getId()) {
33. case R.id.rl:
34. Intent intent = new Intent();
35. intent.putExtra("equipment", itemInfo);
36. setResult(1, intent);
37. finish();
38. break;
39. }
40. }
41. }
42. 5.界面交互程序
43. 1. import android.app.Activity;
  2. import android.content.Intent;
  3. import android.os.Bundle;
  4. import android.view.Menu;
  5. import android.view.MenuItem;

  16. private TextView mLifeTV;
  17. private TextView mAttackTV;
  18. private TextView mSpeedTV;
  20. @Override
  21. protected void onCreate(Bundle savedInstanceState) {
  22. super.onCreate(savedInstanceState);
  23. setContentView(R.layout.activity_main);
  24. mLifeTV = (TextView) findViewById(R.id.tv_life_progress);
  25. mAttackTV = (TextView) findViewById(R.id.tv_attack_progress);
  26. mSpeedTV = (TextView) findViewById(R.id.tv_speed_progress);
  27. initProgress(); //初始化进度条
  28. }
  30. private void initProgress() {
  31. mProgressBar1 = (ProgressBar) findViewById(R.id.progressBar1);
  32. mProgressBar2 = (ProgressBar) findViewById(R.id.progressBar2);
  33. mProgressBar3 = (ProgressBar) findViewById(R.id.progressBar3);
  34. mProgressBar1.setMax(1000); //设置最大值1000
  35. mProgressBar2.setMax(1000);
  36. mProgressBar3.setMax(1000);
  37. }
  39. // 开启新的activity并且想获取他的返回值
  40. public void click(View view) {
  41. Intent intent = new Intent(this, ShopActivity.class);
  42. startActivityForResult(intent, 1); // 返回请求结果,请求码为1
  43. }
  45. public void click2(View view) {
  46. Intent intent = new Intent(this, ShopActivity.class);
  47. startActivityForResult(intent, 1);
  48. }
  50. @Override
  51. protected void onActivityResult(int requestCode, int resultCode, Intent data) {
  52. super.onActivityResult(requestCode, resultCode, data);
  53. if (data != null) {
  54. // 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
  55. if (resultCode == 1) {
  56. if (requestCode == 1) {
  57. ItemInfo info= (ItemInfo) data.getSerializableExtra("equipment");
  58. //更新ProgressBar的值
  59. updateProgress(info);
  60. }
  61. }
  62. }
  63. }
  64. //更新ProgressBar的值
  65. private void updateProgress(ItemInfo info) {
  66. int progress1 = mProgressBar1.getProgress();
  67. int progress2 = mProgressBar2.getProgress();
  68. int progress3 = mProgressBar3.getProgress();
  69. mProgressBar1.setProgress(progress1+info.getLife());
  70. mProgressBar2.setProgress(progress2+info.getAcctack());
  71. mProgressBar3.setProgress(progress3+info.getSpeed());
  72. mLifeTV.setText(mProgressBar1.getProgress()+"");
  73. mAttackTV.setText(mProgressBar2.getProgress() + "");
  74. mSpeedTV.setText(mProgressBar3.getProgress() + "");
  75. }
  77. @Override
  78. public boolean onCreateOptionsMenu(Menu menu) {
  79. // Inflate the menu; this adds items to the action bar if it is present.
  80. getMenuInflater().inflate(R.menu.menu_main, menu);
  81. return true;
  82. }
  84. @Override
  85. public boolean onOptionsItemSelected(MenuItem item) {
  86. // Handle action bar item clicks here. The action bar will
  87. // automatically handle clicks on the Home/Up button, so long
  88. // as you specify a parent activity in AndroidManifest.xml.
  89. int id = item.getItemId();
