学习自慕课网，吐血一滩。。。
首先写布局
<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" > <GridLayout android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/gl_main_game" android:columnCount="5" android:rowCount="3" ></GridLayout> </RelativeLayout>
