标题页面的设计
第一个页面是标题页面，用一个TextView控件显示游戏的名称quanet的世界，然后两个Button控件，一个是continue，一个是exit。
打开Android Studio 4.1.3，选择Create New Project，选择Empty Activity，项目名称为My Game。
首先设计页面的布局，在layout/activity_main.xml中输入
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <TextView android:id="@+id/tv_display" android:layout_width="match_parent" android:layout_height="400dp" android:scrollbars="vertical" android:gravity="center" android:background="#90ee90" android:textSize="30sp"/> <LinearLayout android:layout_width="match_parent" android:layout_height="80dp" android:orientation="horizontal"> <Button android:id="@+id/btn_continue" android:layout_width="180dp" android:layout_height="80dp" android:layout_gravity="center" android:text="continue" /> <Button android:id="@+id/btn_exit" android:layout_width="180dp" android:layout_height="80dp" android:layout_gravity="center" android:text="exit" /> </LinearLayout> </LinearLayout>
然后书写页面的代码，在com/example/mygame/MainActivity.java中输入
package com.example.mygame;
import androidx.appcompat.app.AppCompatActivity;
import android.content.Intent;
import android.os.Bundle;
import android.text.method.ScrollingMovementMethod;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
private TextView tv_display;
private Button btn_continue, btn_exit;
private final String version = "2021-04-10 v2.1";
private final String game_name = "quanet的世界";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tv_display = (TextView) findViewById(R.id.tv_display);
tv_display.setMovementMethod(new ScrollingMovementMethod());
btn_continue = (Button) findViewById(R.id.btn_continue);
btn_exit = (Button) findViewById(R.id.btn_exit);
btn_continue.setOnClickListener(new ClickCAction());
btn_exit.setOnClickListener(new ClickCAction());
String r = "Welcome to\n" + game_name + "\n(" + version + ")\n";
r += "To continue, or exit:\n\n";
tv_display.setText(r);
}
private class ClickCAction implements View.OnClickListener {
@Override
public void onClick(View v) {
if (v.getId() == R.id.btn_continue) {
Intent intent = new Intent();
intent.setClass(MainActivity.this, Introduction.class);
startActivity(intent);
}
if (v.getId() == R.id.btn_exit) {
System.exit(0);
}
}
}
}代码的意思是建立1个TextView对象tv_display，在打开页面时显示欢迎和显示标题。2个Button对象btn_continue和btn_exit，分别绑定点击监听器，点击btn_continue跳转到ActivityIntroduction页面，点击btn_exit退出。
介绍页面的设计
这个页面包括一个TextView控件，用于显示一段简短的剧情，两个Button控件continue和exit用于选择继续和退出。在Android Studio的菜单选择File - New - Activity - Empty Activity，名字为ActivityIntroduction。
接着设计页面的布局，在layout/activity_main.xml中输入
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <TextView android:id="@+id/tv_intro_display" android:layout_width="match_parent" android:layout_height="600dp" android:scrollbars="vertical" android:gravity="left|top" android:background="#90ee90" android:textSize="20sp"/> <LinearLayout android:layout_width="match_parent" android:layout_height="80dp" android:orientation="horizontal"> <Button android:id="@+id/btn_intro_continue" android:layout_width="180dp" android:layout_height="80dp" android:layout_gravity="center" android:text="continue" /> <Button android:id="@+id/btn_intro_exit" android:layout_width="180dp" android:layout_height="80dp" android:layout_gravity="center" android:text="exit" /> </LinearLayout> </LinearLayout>
接着编写代码，在com/example/mygame/ActivityIntroduction.java中输入
package com.example.mygame;
import androidx.appcompat.app.AppCompatActivity;
import android.content.Intent;
import android.os.Bundle;
import android.text.method.ScrollingMovementMethod;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
public class Introduction extends AppCompatActivity {
private TextView tv_intro_display;
private Button btn_intro_continue, btn_intro_exit;
private String game_process;
private StringBuilder b = new StringBuilder( "" );
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_introduction);
tv_intro_display = (TextView) findViewById(R.id.tv_intro_display);
tv_intro_display.setMovementMethod(new ScrollingMovementMethod());
btn_intro_continue = (Button) findViewById(R.id.btn_intro_continue);
btn_intro_exit = (Button) findViewById(R.id.btn_intro_exit);
btn_intro_continue.setOnClickListener(new ClickCAction());
btn_intro_exit.setOnClickListener(new ClickCAction());
String r = "【quanet】我...我在哪？\n";
tv_intro_display.setText(r);
game_process = "1";
}
private class ClickCAction implements View.OnClickListener {
@Override
public void onClick(View v) {
if (v.getId() == R.id.btn_intro_continue) {
if (game_process == "1") {
b.delete(0, b.length());
b.append("【老地精】来我这里接任务...\n");
b.append("【quanet】......\n");
b.append("2. To continue: \n\n");
tv_intro_display.setText(b);
game_process = "2";
} else if (game_process == "2") {
b.delete(0, b.length());
b.append( "【老地精】去山洞里面的最尽头寻找【狼皮】...\n" );
b.append( "【quanet】...\n" );
b.append( "【quanet】好吧...\n" );
b.append( "提示（到达山洞尽头方法）：先down至(0, -10)，然后right至(10, -10)，最后up至(10, 0)。\n" );
b.append("3. To continue: \n\n");
tv_intro_display.setText(b);
game_process = "3";
} else if (game_process == "3") {
Intent intent = new Intent();
intent.setClass(Introduction.this, C01_cave.class);
startActivity(intent);
}
}
if (v.getId() == R.id.btn_intro_exit) {
System.exit(0);
}
}
}
}山洞页面的设计
这个页面包括4个TextView控件，分别显示标题、地图、坐标、消息。10个Button控件，用于执行不同的功能。在Android Studio的菜单选择File - New - Activity - Empty Activity，名字为Activity01Cave。
首先设计TextView控件的显示样式，背景和边框使用不同的颜色。在drawable/textview_border.xml中输入
<?xml version="1.0" encoding="utf-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle"> <solid android:color="#a9a9a9" /> <stroke android:width="1dp" android:color="#98fb98"/> </shape>
接着编写这个页面的布局代码，在layout/activity_activity01_cave.xml中输入
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <TextView android:id="@+id/tv_header" android:layout_width="match_parent" android:layout_height="40dp" android:scrollbars="vertical" android:gravity="left|top" android:background="@drawable/textview_border" android:textSize="24dp" /> <TextView android:id="@+id/tv_map" android:layout_width="match_parent" android:layout_height="150dp" android:scrollbars="vertical" android:gravity="left|top" android:textSize="14dp" android:background="@drawable/textview_border"/> <TextView android:id="@+id/tv_coordinates" android:layout_width="match_parent" android:layout_height="50dp" android:gravity="left|top" android:background="@drawable/textview_border" android:textSize="14dp" /> <TextView android:id="@+id/tv_messages" android:layout_width="match_parent" android:layout_height="300dp" android:scrollbars="vertical" android:gravity="left|top" android:background="@drawable/textview_border" android:textSize="14dp" /> <LinearLayout android:layout_width="match_parent" android:layout_height="80dp" android:orientation="vertical"> <LinearLayout android:layout_width="match_parent" android:layout_height="40dp" android:orientation="horizontal"> <Button android:id="@+id/btn_q" android:layout_width="70dp" android:layout_height="40dp" android:layout_gravity="center" android:text="Q" /> <Button android:id="@+id/btn_w" android:layout_width="70dp" android:layout_height="40dp" android:layout_gravity="center" android:text="W" /> <Button android:id="@+id/btn_e" android:layout_width="70dp" android:layout_height="40dp" android:layout_gravity="center" android:text="E" /> <Button android:id="@+id/btn_r" android:layout_width="70dp" android:layout_height="40dp" android:layout_gravity="center" android:text="R" /> <Button android:id="@+id/btn_F1" android:layout_width="80dp" android:layout_height="40dp" android:layout_gravity="center" android:text="F1" /> </LinearLayout> <LinearLayout android:layout_width="match_parent" android:layout_height="40dp" android:orientation="horizontal"> <Button android:id="@+id/btn_a" android:layout_width="70dp" android:layout_height="40dp" android:layout_gravity="center" android:text="A" /> <Button android:id="@+id/btn_s" android:layout_width="70dp" android:layout_height="40dp" android:layout_gravity="center" android:text="S" /> <Button android:id="@+id/btn_d" android:layout_width="70dp" android:layout_height="40dp" android:layout_gravity="center" android:text="D" /> <Button android:id="@+id/btn_f" android:layout_width="70dp" android:layout_height="40dp" android:layout_gravity="center" android:text="F" /> <Button android:id="@+id/btn_F2" android:layout_width="80dp" android:layout_height="40dp" android:layout_gravity="center" android:text="F2" /> </LinearLayout> </LinearLayout> </LinearLayout>
接着编写代码文件，在com/example/mygame/Activity01Cave.java中输入
package com.example.mygame;
import androidx.appcompat.app.AppCompatActivity;
import android.content.Intent;
import android.os.Bundle;
import android.text.method.ScrollingMovementMethod;
import android.view.View;
import android.widget.TextView;
public class Activity01Cave extends AppCompatActivity {
private TextView tv_header, tv_map, tv_coordinates, tv_messages;
private Basic hero;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_activity01_cave);
tv_header = (TextView) findViewById(R.id.tv_header);
tv_map = (TextView) findViewById(R.id.tv_map);
tv_map.setMovementMethod(new ScrollingMovementMethod());
tv_coordinates = (TextView) findViewById(R.id.tv_coordinates);
tv_messages = (TextView) findViewById(R.id.tv_messages);
tv_messages.setMovementMethod(new ScrollingMovementMethod());
findViewById(R.id.btn_q).setOnClickListener(new ClickCAction());
findViewById(R.id.btn_w).setOnClickListener(new ClickCAction());
findViewById(R.id.btn_e).setOnClickListener(new ClickCAction());
findViewById(R.id.btn_r).setOnClickListener(new ClickCAction());
findViewById(R.id.btn_F1).setOnClickListener(new ClickCAction());
findViewById(R.id.btn_a).setOnClickListener(new ClickCAction());
findViewById(R.id.btn_s).setOnClickListener(new ClickCAction());
findViewById(R.id.btn_d).setOnClickListener(new ClickCAction());
findViewById(R.id.btn_f).setOnClickListener(new ClickCAction());
findViewById(R.id.btn_F2).setOnClickListener(new ClickCAction());
tv_header.setText("第一幕 山洞");
setMap();
setHint();
hero = new Basic();
hero.setStatus("before_introduction");
hero.display_coordinates(tv_coordinates);
}
private class ClickCAction implements View.OnClickListener {
@Override
public void onClick(View v) {
if (v.getId() == R.id.btn_F1) {
setHint();
}
if (v.getId() == R.id.btn_F2) {
System.exit( 0 );
}
if (v.getId() == R.id.btn_w) {
hero.change_y_coordinate(1, tv_coordinates);
hero.make_event(tv_messages);
}
if (v.getId() == R.id.btn_s) {
hero.change_y_coordinate(-1, tv_coordinates);
hero.make_event(tv_messages);
}
if (v.getId() == R.id.btn_a) {
hero.change_x_coordinate(-1, tv_coordinates);
hero.make_event(tv_messages);
}
if (v.getId() == R.id.btn_d) {
hero.change_x_coordinate(1, tv_coordinates);
hero.make_event(tv_messages);
}
if (v.getId() == R.id.btn_q) {
//hero.display_full_attribution(tv_messages);
Intent intent = new Intent();
intent.setClass(C01_cave.this, Activity_Character.class);
intent.putExtra("name", hero.getName());
intent.putExtra("profession", hero.getProfession());
intent.putExtra("lv", hero.getLv());
intent.putExtra("potential", hero.getPotential());
intent.putExtra("HP", hero.getHP());
intent.putExtra("HP_max", hero.getHP_max());
intent.putExtra("MP", hero.getMP());
intent.putExtra("MP_max", hero.getMP_max());
intent.putExtra("attack", hero.getAttack());
intent.putExtra("defence", hero.getDefence());
intent.putExtra("strength", hero.getStrength());
intent.putExtra("quickness", hero.getQuickness());
intent.putExtra("intelligence", hero.getIntelligence());
intent.putExtra("luck", hero.getLuck());
intent.putExtra("Exp", hero.getExp());
intent.putExtra("Exp_max", hero.getExp_max());
intent.putExtra("coin", hero.getCoin());
startActivity(intent);
}
if (v.getId() == R.id.btn_e) {
//hero.display_equipments(tv_messages);
Intent intent = new Intent();
intent.setClass(C01_cave.this, Activity_Equipment.class);
intent.putExtra("shirt", hero.getEquipment("shirt"));
intent.putExtra("long_underwear", hero.getEquipment("long_underwear"));
intent.putExtra("helmet", hero.getEquipment("helmet"));
intent.putExtra("breastplate", hero.getEquipment("breastplate"));
intent.putExtra("cloak", hero.getEquipment("cloak"));
intent.putExtra("gloves", hero.getEquipment("gloves"));
intent.putExtra("belt", hero.getEquipment("belt"));
intent.putExtra("shoes", hero.getEquipment("shoes"));
intent.putExtra("lefthand_item", hero.getEquipment("lefthand_item"));
intent.putExtra("righthand_item", hero.getEquipment("righthand_item"));
startActivity(intent);
}
if (v.getId() == R.id.btn_r) {
//hero.print_backpack(tv_messages);
Intent intent = new Intent();
intent.setClass(C01_cave.this, Activity_BackPack.class);
intent.putExtra("names", hero.getBackPackItemNames());
intent.putExtra("nums", hero.getBackPackItemNums());
startActivity(intent);
}
}
}
public void setMessage(String b) {
tv_messages.setText(b);
}
public void setMap() {
String s = "地图：\n";
s += "1. 草药（-5 < x < 15, -15 < y < 5）\n";
s += "2. 史莱姆（x = 0, -10 < y < 0），术士、蝙蝠（0< x < 10, y = -10），骷髅（x=10, -10 < y < 0）\n";
s += "3. 药店（x = 0, y = 0）\n";
tv_map.setText(s);
}
public void setHint() {
tv_messages.setText("提示：\n" + "移动：上W左A下S右D，攻击F，人物状态Q，装备E，背包R，提示F1，退出F2。");
}
}这里用到了一个自编的Basic类，里面包含了英雄角色的基本信息，以及对于角色各种动作的响应。
