学习Android的基本开发也有一段时间了，可是由于没有常常使用Android渐渐的也就忘记了。
Android编程学的不深，不过为了对付逆向，可是有时还是会感到力不从心的。毕竟不是一个计算机专业毕业的Coder，相对来说编程的基础对于以后非常多方面的学习都是非常重要的，特别是想在软件安全或软件的企业开发的过程中有所进步，必需要计算机专业知识扎实。
不多说了，发个Android版的俄罗斯方块，当然基本框架是參照之前的学的C语言版的俄罗斯方块的。俄罗斯方块程序的开发方法比較多，感觉使用数组的方法去实现还是非常方便的。以下看代码的详细实现。
俄罗斯方块界面显示代码的实现：
//俄罗斯方块界面的显示package com.example.mytetris;import android.content.Context;import android.graphics.Canvas;import android.graphics.Color;import android.graphics.Paint;import android.util.AttributeSet;import android.util.DisplayMetrics;import android.view.View;import android.view.WindowManager;public class GameUI extends View{public Game m_Game = null;private byte[][] m_Groundback = null;private Paint m_Paint = new Paint(); //画刷private final int PADDING = 2; private int m_TetrisWidth = 0;@Overrideprotected void onDraw(Canvas canvas) { //设置背景颜色setBackgroundColor(Color.BLACK);//画背景drawGoundback(canvas);//画方块int nX = m_Game.m_nX;int nY = m_Game.m_nY;if (m_Game.m_CurrBlock == null)return;byte[][] data = m_Game.m_CurrBlock;for (int i = 0; i < 4; i++){for (int j = 0; j < 4; j++){if (data[i][j] == Game.ISWALL){int nLeft = nX * m_TetrisWidth + j * m_TetrisWidth;int nTop = nY * m_TetrisWidth + i * m_TetrisWidth;//外框m_Paint.setColor(Color.WHITE);canvas.drawRect(nLeft, nTop, nLeft + m_TetrisWidth, nTop + m_TetrisWidth, m_Paint);//内框m_Paint.setColor(Color.GREEN);canvas.drawRect(nLeft + PADDING, nTop + PADDING, nLeft + m_TetrisWidth - PADDING, nTop +m_TetrisWidth - PADDING, m_Paint);}}}}private void drawGoundback(Canvas canvas){//获取背景m_Groundback = m_Game.getGroundback();for (int i = 0; i < Game.NROWS; i++) {for (int j = 0; j < Game.NCOLS; j++) {if (m_Groundback[i][j] == Game.ISWALL){//画白色的方块--外框m_Paint.setColor(Color.WHITE);canvas.drawRect(j*m_TetrisWidth, i*m_TetrisWidth, (j+1)*m_TetrisWidth, (i+1)*m_TetrisWidth, m_Paint);//画绿色的方块--内框m_Paint.setColor(Color.GREEN);canvas.drawRect(j*m_TetrisWidth + PADDING, i*m_TetrisWidth + PADDING,(j+1)*m_TetrisWidth - PADDING, (i+1)*m_TetrisWidth - PADDING, m_Paint);}}}}public GameUI(Context context, AttributeSet attrs, int defStyleAttr){super(context, attrs, defStyleAttr);}//自己定义view组件。构造调用该函数public GameUI(Context context, AttributeSet attrs){super(context, attrs);//创建Gamem_Game = new Game();//获取手机分辨率WindowManager wmgr = (WindowManager)context.getSystemService(Context.WINDOW_SERVICE);DisplayMetrics outMetrics = new DisplayMetrics();wmgr.getDefaultDisplay().getMetrics(outMetrics);//手机屏幕宽度int nTetrisWidth = outMetrics.widthPixels;//依据手机分辨率。设置方块宽度m_TetrisWidth = nTetrisWidth/Game.NCOLS*3/4;}public GameUI(Context context){super(context);}}
俄罗斯方块详细的逻辑的实现：

俄罗斯方块主体的控制流程的代码实现：

执行效果图，界面做的比較挫：
Android俄罗斯方块的代码实现还不全，有兴趣的Coder能够完好一下。网上Android版俄罗斯方块代码到处都是，可是我认为这份代码给出了俄罗斯方块编写的基本框架，依照这个框架。能够写出非常多语言版本号的俄罗斯方块。
