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*/

}

3)自定义的格子视图

/*** @Project App_Imooc* @Package com.android.imooc.myui* @author chenlin* @version 1.0* @Date 2014年3月1日* @Note 自定义的格子视图*/
public class XGridView extends GridView {public static final int WORD_COUNTS = 24;public static final int WORD_SELECT_COUNTS = 4;private GridAdapter mAdapter;private List<WordButton> mDatas = new ArrayList<WordButton>();private Context mContext;private Animation mScaleAnimation;private OnWordButtonClickListener mListener;public interface OnWordButtonClickListener{void onButtonClick(WordButton button);}public void setOnWordButtonClickListener(OnWordButtonClickListener listener){this.mListener = listener;}public XGridView(Context context, AttributeSet attrs) {super(context, attrs);this.mContext = context;mAdapter = new GridAdapter();setAdapter(mAdapter);}public void updateData(List<WordButton> datas){this.mDatas = datas;setAdapter(mAdapter);;}public XGridView(Context context) {this(context, null);}/*** @Project App_Imooc* @Package com.android.imooc.myui* @author chenlin* @version 1.0* @Note 适配器*/private class GridAdapter extends BaseAdapter {private LayoutInflater mInflater;public GridAdapter(){mInflater = LayoutInflater.from(mContext);}@Overridepublic int getCount() {if (mDatas != null) {return mDatas.size();}return 0;}@Overridepublic Object getItem(int position) {if (mDatas != null) {return mDatas.get(position);}return null;}@Overridepublic long getItemId(int position) {return position;}@Overridepublic View getView(int position, View view, ViewGroup parent) {final WordButton holder;if (view == null) {holder = mDatas.get(position);view = mInflater.inflate(R.layout.item_gridview, parent, false);//加载动画mScaleAnimation = AnimationUtils.loadAnimation(mContext, R.anim.scale);//依次设置延迟时间mScaleAnimation.setStartOffset(position * 100);holder.button = (Button) view.findViewById(R.id.item_btn);holder.index = position;view.setTag(holder);}else {holder = (WordButton) view.getTag();}holder.button.setText(holder.name);holder.button.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {if (mListener != null) {if (v.getTag() != null) {WordButton holder = (WordButton) v.getTag();mListener.onButtonClick(holder);}}}});//播放动画view.startAnimation(mScaleAnimation);return view;}}}

4）歌曲实体类

/*** 歌曲实体类* @Project    App_Imooc* @Package    com.android.imooc.bean* @author     chenlin* @version    1.0* @Date       2014年3月7日* @Note       TODO*/
public class Song {private String name;//歌曲名称private String filename;//文件名称private int nameLength;//文件名称长度public char[] getNameChar(){//得到名称里的一个个文字return name.toCharArray();}public String getName() {return name;}public void setName(String name) {this.name = name;this.nameLength = name.length();}public String getFilename() {return filename;}public void setFilename(String filename) {this.filename = filename;}public int getNameLength() {return nameLength;}//  public void setNameLength(int nameLength) {//      this.nameLength = nameLength;
//  }}

5)文字按钮实体类：

/*** 文字按钮* * @Project App_Imooc* @Package com.android.imooc.bean* @author chenlin* @version 1.0* @Date 2014年3月1日* @Note TODO*/
public class WordButton {/*** 搜索的索引*/public int index;/*** 是否可见*/public boolean isVisible;/*** 按钮上面的文字*/public String name;/*** 按钮*/public Button button;public WordButton() {this.isVisible = true;this.name = "";}}
