Android(安卓)猜歌曲游戏开发

一、界面如图：
1)主界面

2）对话框界面

3)过关界面

4)通关界面

二、实现步骤

三、详细代码
1）主界面代码：

   }}

2）通关界面：

/** * 通关后的界面 * @Project App_Imooc * @Package com.android.imooc.song * @author chenlin * @version 1.0 * @Date 2014年3月18日 * @Note TODO */public class PassActivity extends Activity {    private ImageButton mBtnBack;    private ImageButton mBtnShare;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.all_pass_view);        initViews();        initEvents();    }    private void initEvents() {        mBtnBack.setOnClickListener(new OnClickListener() {            @Override            public void onClick(View v) {                int coins = GameUtil.loadData(PassActivity.this)[GameUtil.DATA_COIN];                //过完关后初始化数据                GameUtil.saveData(PassActivity.this, 0, coins);                startActivity(new Intent(PassActivity.this, MainActivity.class));                finish();            }        });        mBtnShare.setOnClickListener(new OnClickListener() {            @Override            public void onClick(View v) {                WeiXinHelper.getInstance(PassActivity.this).sendRequest("我正在玩疯狂猜歌游戏,一起来玩吧!");            }        });    }    private void initViews() {        //隐藏右上角的总金额图标        findViewById(R.id.flayout_coin).setVisibility(View.INVISIBLE);        mBtnBack = (ImageButton) findViewById(R.id.btn_bar_back);        mBtnShare = (ImageButton) findViewById(R.id.btn_share_weixin);    }}

3)自定义的格子视图
