[Android]SurfaceView繪製奔跑的小人

轉自：http://blog.csdn.net/xiaoxiaobian3310903/article/details/7971962

原文源代碼使用的是橫屏顯示，奔跑的小人多是因爲座標緣由沒法顯示在屏幕上，在這裏我只做了正常豎屏顯示

 

代碼以下：

import android.content.Context;

import android.graphics.BitmapFactory;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;

import android.view.SurfaceHolder.Callback;

        setContentView(view);
    }

程序運行效果（靜態），由於沒法截取動態奔跑
