this is my code!是不是loadTexture里有问题？
protected static int loadTexture(GL10 gl,Bitmap bmp, boolean
reverseRGB) {

int[] tmp_texture = new int[1];
gl.glGenTextures(1, tmp_texture, 0);
int texture = tmp_texture[0] ;//QQ
System.out.println("k=0 loadTexture 11111 in GLTutorialBase");
ByteBuffer bb = ByteBuffer.allocateDirect(bmp.getHeight()
*bmp.getWidth()*4);
bb.order(ByteOrder.BIG_ENDIAN);
IntBuffer ib = bb.asIntBuffer();
System.out.println("k=0 loadTexture 22222 in
GLTutorialBase");
for (int y=bmp.getHeight()-1;y>-1;y--)
for (int x=0;x<bmp.getWidth();x++) {
int pix = bmp.getPixel(x,bmp.getHeight()-y-1);
// Convert ARGB -> RGBA
@SuppressWarnings("unused")
byte alpha = (byte)((pix >> 24)&0xFF);
byte red = (byte)((pix >> 16)&0xFF);
byte green = (byte)((pix >> 8)&0xFF);
byte blue = (byte)((pix)&0xFF);
// It seems like alpha is currently broken in
Android...
ib.put(red << 24 | green << 16 | blue << 8 |
0xFF);//255-alpha);
}
