}}

3、使用MainActivity

public class MainActivity extends AppCompatActivity { private GobangPanel panel; protected voID onCreate(Bundle savedInstanceState) {  super.onCreate(savedInstanceState);  setContentVIEw(R.layout.activity_main);  panel = this.findVIEwByID(R.ID.gobang_panel);  panel.setListener(new GobangPanel.OnFinishListener() {   @OverrIDe   public voID onFinish(boolean mIsWhiteWinner) {    initDialog(mIsWhiteWinner);   }  }); } /**  * 初始化d框  */ private voID initDialog(boolean mIsWhiteWinner) {  AlertDialog dialog = new AlertDialog.Builder(this)    //.setTitle("这是标题")    .setMessage(mIsWhiteWinner ? "白棋胜利，是否重新开始？" : "黑棋胜利，是否重新开始？")    //.setIcon(R.mipmap.ic_launcher)    .setPositivebutton("确定",new DialogInterface.OnClickListener() {//添加"Yes"按钮     @OverrIDe     public voID onClick(DialogInterface dialogInterface,int i) {      panel.start();     }    })//    .setNegativebutton("取消",new DialogInterface.OnClickListener() {//添加取消//     @OverrIDe//     public voID onClick(DialogInterface dialogInterface,int i) {//      Toast.makeText(MainActivity.this,"这是取消按钮",Toast.LENGTH_SHORT).show();//     }//    })    //方法一：setCanceledOntouchOutsIDe(false);按对话框以外的地方不起作用。按返回键起作用    //方法二：setCanceleable(false);按对话框以外的地方不起作用。按返回键也不起作用    .setCancelable(false)    .create();  dialog.show(); }}

对应布局文件：activity_main：

<horizontalscrollview xmlns:androID="http://schemas.androID.com/apk/res/androID" xmlns:tools="http://schemas.androID.com/tools" androID:layout_wIDth="match_parent" androID:layout_height="match_parent" androID:background="#fff" tools:context=".MainActivity"> <ScrollVIEw  androID:layout_wIDth="match_parent"  androID:layout_height="match_parent">  <com.helloworld.game.GobangPanel   androID:ID="@+ID/gobang_panel"   androID:layout_wIDth="1000dp"   androID:layout_height="1000dp"   androID:layout_centerInParent="true" /> </ScrollVIEw></horizontalscrollview>
