編輯：關於Android編程
游戲頁面有幾個小游戲，因為時間原因只做了第一個猜成語，是用的選擇題方式，十道題以內答對六題算闖關成功。
目標效果：
以下是具體操作過程
1.新建GameActivity.java頁面和activity_game.xml頁面，activity_game.xml作為顯示游戲目錄頁面：
activity_game.xml頁面：
2.新建GameGuessActivity.java頁面和activity_game_guess.xml頁面，activity_game_guess.xml頁面顯示猜成語游戲規則。 activity_game_guess.xml頁面：
3.新建PlayGuessActivity.java頁面和activity_play_guess.xml頁面，activity_play_guess.xml頁面作為猜成語游戲界面。 activity_play_guess.xml頁面：
4.GameActivity.java頁面跳轉每一個游戲頁面。 GameActivity.java頁面：
package cn.edu.bztc.happyidion.activity;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
import android.widget.TextView;
public class GameActivity extends Activity {
private Intent intent;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_game);
}
public void gamePlay(View view) {
switch (view.getId()) {
case R.id.tvGameGuess:
intent=new Intent(this,GameGuessActivity.class);
startActivity(intent);
break;
case R.id.tvGameConn:
break;
default:
break;
}
}
}
5.GameGuessActivity.java頁面點擊編寫開始游戲點擊事件。
GameGuessActivity.java頁面：
package cn.edu.bztc.happyidion.activity;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
public class GameGuessActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_game_guess);
}
public void startGame(View view){
switch (view.getId()) {
case R.id.ibStartGame:
Intent intent=new Intent(this,PlayGuessActivity.class);
startActivity(intent);
finish();
break;
default:
break;
}
}
}
6.GameDao.java頁面定義游戲中對成語表的查詢方法。
GameDao.java頁面：
package cn.edu.bztc.happyidiom.dao;
import java.util.ArrayList;
import java.util.List;
import android.content.ContentValues;
import android.content.Context;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.util.Log;
import cn.edu.bztc.happyidiom.db.DBOpenHelper;
import cn.edu.bztc.happyidiom.db.MyDatabaseHelper;
import cn.edu.bztc.happyidiom.entity.Animal;
public class GameDao {
private static GameDao gameDao;
private SQLiteDatabase db;
public GameDao(Context context){
DBOpenHelper dbHelper=new DBOpenHelper(context);
db=dbHelper.openDatabase();
}
public synchronized static GameDao getInstance(Context context){
if(gameDao==null){
gameDao=new GameDao(context);
}
return gameDao;
}
/*根據id獲取成語信息*/
public Animal getPhrase(String id){
Animal animal = null;
Cursor cursor=db.query("animal",null,"_id=?",new String[]{id},null,null,null);
if(cursor.moveToFirst()){
animal=new Animal();
animal.setId(cursor.getInt(cursor.getColumnIndex("_id")));
animal.setName(cursor.getString(cursor.getColumnIndex("name")));
animal.setPronounce(cursor.getString(cursor.getColumnIndex("pronounce")));
animal.setAntonym(cursor.getString(cursor.getColumnIndex("antonym")));
animal.setHomoionym(cursor.getString(cursor.getColumnIndex("homoionym")));
animal.setDerivation(cursor.getString(cursor.getColumnIndex("derivation")));
animal.setExamples(cursor.getString(cursor.getColumnIndex("examples")));
animal.setExplain(cursor.getString(cursor.getColumnIndex("explain")));
}
cursor.close();
return animal;
}
}
7.PlayGuessActivity.java頁面為游戲界面。
PlayGuessActivity.java頁面：
package cn.edu.bztc.happyidion.activity;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
