java-动态绘制多维数据集时出现问题

概述我有一个声明为的float数组camObjCoord.public static float camObjCoord [] = new float [8000];然后,我将其索引填充到一个类似以下内容的类中. public void addcube(float highx, float lowx, float hig

我有一个声明为的float数组camObjCoord.

public static float camObjCoord [] = new float [8000];

然后,我将其索引填充到一个类似以下内容的类中.

                      public voID addcube(float highx,float lowx,float highz,float lowz){    //Constructing new cube...    System.out.println("f = " + f);    Global.cubes++;    float y = 1.5f;    System.out.println("highx = " + highx + "lowx = " + lowx + "highz = " + highz + "lowz = " + lowz);    //FRONT    camObjCoord[i] = lowx;     i++;    camObjCoord[i] = -y;     i++;    camObjCoord[i] = highz;     i++;    camObjCoord[i] = highx;     i++;    camObjCoord[i] = -y;     i++;    camObjCoord[i] = highz;     i++;    camObjCoord[i] = lowx;     i++;    camObjCoord[i] = y;     i++;    camObjCoord[i] = highz;     i++;    camObjCoord[i] = highx;     i++;    camObjCoord[i] = y;     i++;    camObjCoord[i] = highz;    //BACK     i++;    camObjCoord[i] = lowx;     i++;    camObjCoord[i] = -y;     i++;    camObjCoord[i] = lowz;     i++;    camObjCoord[i] = lowx;     i++;    camObjCoord[i] = y;     i++;    camObjCoord[i] = lowz;     i++;    camObjCoord[i] = highx;     i++;    camObjCoord[i] = -y;     i++;    camObjCoord[i] = lowz;     i++;    camObjCoord[i] = highx;     i++;    camObjCoord[i] = y;     i++;    camObjCoord[i] = lowz;     i++;    //left    camObjCoord[i] = lowx;     i++;    camObjCoord[i] = -y;     i++;    camObjCoord[i] = highz;     i++;    camObjCoord[i] = lowx;     i++;    camObjCoord[i] = y;     i++;    camObjCoord[i] = highz;     i++;    camObjCoord[i] = lowx;     i++;    camObjCoord[i] = -y;     i++;    camObjCoord[i] = lowz;     i++;    camObjCoord[i] = lowx;     i++;    camObjCoord[i] = y;     i++;    camObjCoord[i] = lowz;     i++;    //RIGHT    camObjCoord[i] = highx;     i++;    camObjCoord[i] = -y;     i++;    camObjCoord[i] = lowz;     i++;    camObjCoord[i] = highx;     i++;    camObjCoord[i] = y;     i++;    camObjCoord[i] = lowz;     i++;    camObjCoord[i] = highx;     i++;    camObjCoord[i] = -y;     i++;    camObjCoord[i] = highz;     i++;    camObjCoord[i] = highx;     i++;    camObjCoord[i] = y;     i++;    camObjCoord[i] = highz;     i++;    //top    camObjCoord[i] = lowx;     i++;    camObjCoord[i] = y;     i++;    camObjCoord[i] = highz;     i++;    camObjCoord[i] = highx;     i++;    camObjCoord[i] = y;      i++;    camObjCoord[i] = highz;     i++;    camObjCoord[i] = lowx;     i++;    camObjCoord[i] = y;     i++;    camObjCoord[i] = highz;     i++;    camObjCoord[i] = highx;     i++;    camObjCoord[i] = y;     i++;    camObjCoord[i] = lowz;     i++;    //BottOM    camObjCoord[i] = lowx;     i++;    camObjCoord[i] = -y;     i++;    camObjCoord[i] = highz;     i++;    camObjCoord[i] = lowx;     i++;    camObjCoord[i] = -y;     i++;    camObjCoord[i] = lowz;     i++;    camObjCoord[i] = highx;     i++;    camObjCoord[i] = -y;     i++;    camObjCoord[i] = highz;     i++;    camObjCoord[i] = highx;     i++;    camObjCoord[i] = -y;     i++;    camObjCoord[i] = lowz;    i++;    int p = 0;    System.out.println("FulL ARRAY");    while(p < 72){        System.out.println(camObjCoord[p]);        p++;    }}

然后我打电话给makevIEw()

    public voID makevIEw() {     Intent myIntent = new Intent(this,GLCamTest.class);        Bundle b = new Bundle();        b.putfloatArray("tweets",camObjCoord);        myIntent.putExtras(b);    this.startActivity(myIntent);}

然后在新课程中…

public voID onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    Bundle b = this.getIntent().getExtras();    float original[] = b.getfloatArray("tweets");    camObjCoord = original;    counter++;}   

然后,我还有另一个类GLLayer,它的外观如下所示.http://pastebin.org/394884在该类中,我正在从float数组中绘制多维数据集,我已经检查过了,并且确实存在多维数据集的值,当我m在其中编码数组可以工作,但是当我动态构建数组然后将其传递时,立方体无法绘制.我这样叫课.

           glVIEw=new GLLayer(this);           mPrevIEw = new CamLayer(this,glVIEw); 

有人知道为什么吗？我该如何解决我的问题？只是要补充一点,我在动态绘制时将完全相同的值赋予完全相同的索引

          final static float camObjCoord[] = new float[] {            // FRONT             -2.0f,-1.5f,2.0f,-2.0f,1.5f,// BACK             -2.0f,// left             -2.0f,// RIGHT              2.0f,// top             -2.0f,// BottOM             -2.0f,};

然后它将渲染此多维数据集.似乎不喜欢我先创建数组,然后动态添加索引.为什么？我该如何解决？为了获得奖励,我还将接受一个适用于AndroID的适当解决方法.

谢谢.

edit1：我尝试过各种事情,如果不是像这样声明数组,那不是数组的传递导致问题.

edit2：我也尝试过将数组放入GLLayer(渲染多维数据集的类)时进行打印,一切都与您期望的一样.我不知道为什么这些立方体不会出现:(

edit3：我已经添加了如何构造float数组.

edit4：我也尝试将数组的大小设置为等于我输入的值的数量.不起作用

最佳答案我会稍微减少这个问题.如果您要使数组足够大以仅容纳一个多维数据集,并以相同的方式填充它(但仅填充一次),那么它将起作用吗？如果您将它放大到足以容纳两个多维数据集,并为其提供两个多维数据集的数据该怎么办？ 总结
