动态壁纸----线条

 
在原基础上进修了修改，一下贴出增加的代码：
 
private int x_point = 0;// 保存x坐标
     private int y_point = 0;// 保存y坐标
     private int height = 0;// 保存屏幕的长度
     private int width = 0;// 保存屏幕的宽度
     private int count;
     private int i = 0;
 
 
 
效果实现代码：
mPaint.setAntiAlias(true);
            mPaint.setColor(Color.BLUE);
