这两天 闲的没事想起来写一个 小游戏练练手，也为了巩固 基础知识吧 ，这段时间我会定期的 写一些小项目。 今天第一篇： 扫雷——Android 版
第一： 新建项目
1： 布局文件：
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/root" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" > <LinearLayout android:layout_centerInParent="true" android:id="@+id/linear_map" android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="vertical" > </LinearLayout> </RelativeLayout>
2 MainActivity
