2、gobangpanel棋盘面板:

} super.onrestoreinstancestate(state); } /** * 游戏结束回调 */ public onfinishlistener listener; public void setlistener(onfinishlistener listener) { this.listener = listener; } public interface onfinishlistener { void onfinish(boolean miswhitewinner); } }
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); } }); } /** * 初始化弹框 */ 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>
