Android开发之2048安卓版

之前是在eclipse上写的，后面换成了android sudio。

2048游戏的UI整体可以采用线性布局，即LinearLayout，其中嵌套一个线性布局和一个GridLayout，内嵌的线性布局填充文本框，以显示分数，GridLayout中填充4×4的继承自FrameLayout的card类作为主要的游戏界面。由于大部分操作都在GridLayout中进行，可以自定义一个继承自GridLayout的类GameView，类中定义判定上下左右滑动的方法和每次滑动后自动添加一个随机数字的方法以及每次滑动后判断游戏是否可以继续进行的方法。

主布局activity_main.xml代码如下

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:tools="http://schemas.android.com/tools"android:id="@+id/container"//match_parent表示布局充满整个屏幕android:layout_width="match_parent"android:layout_height="match_parent"tools:context="com.example.administractor.game2048.MainActivity"//里面的组件垂直放置android:orientation="vertical"tools:ignore="MergeRootFrame"><LinearLayout//宽度充满整个屏幕，高度自适应。android:layout_width="fill_parent"android:layout_height="wrap_content"android:orientation="horizontal" >//显示当前分数的文本框<TextView android:layout_width="wrap_content"android:layout_height="wrap_content"android:text="Your Score:"/><TextViewandroid:id="@+id/tvScore"android:layout_width="wrap_content"android:layout_height="wrap_content"/></LinearLayout>//使用自定义的GridLayout<com.example.administractor.game2048.GameViewandroid:layout_width="fill_parent"android:layout_height="0dp"android:layout_weight="1"android:id="@+id/GameView" ></com.example.administractor.game2048.GameView> </LinearLayout>
