完成了LabVIEW上的2048之后。。最近学了几周的Android，所以就想用Android实现一下。。
百度了不少方案 ，有View，GridView，我就突发奇想……想用TextView实现一下，然后就有了大概的思路：用一个二维数组然后在运算的过程中实时更新TextView的属性，并加入了计分和最高分记录与回显。 上代码！
1.首先是布局文件
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center_horizontal"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="100dp"
android:orientation="horizontal" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="40dp"
android:text="Score:"
android:textColor="#CCC0B3" />
<TextView
android:id="@+id/score"
android:layout_width="60dp"

BufferedReader reader = new BufferedReader(new InputStreamReader(fis)); // 构建字符流对象
String text = reader.readLine();
reader.close();
if (!TextUtils.isEmpty(text)) {
String[] split = text.split("##");
Map<String, String> userInfoMap = new HashMap<String, String>();
userInfoMap.put("Score", split[0]);
userInfoMap.put("BestScore", split[1]);
return userInfoMap;
}
} catch (Exception e) {
// TODO Auto-generated catch block

}
return null;
}
}
最终效果：
