Android 纹理不应用于网格-OpenGL

我正在使用OpenGLES。我已经成功加载了obj文件（网格）并显示良好，但当我应用纹理时，它不会显示

我在下面添加了代码

public void draw(GL10 gl) {
    // bind the previously generated texture
    gl.glBindTexture(GL10.GL_TEXTURE_2D, textures[0]);
    gl.glEnableClientState(GL10.GL_VERTEX_ARRAY);
    gl.glEnableClientState(GL10.GL_TEXTURE_COORD_ARRAY);
    // Set the face rotation
    gl.glFrontFace(GL10.GL_CW);

    gl.glVertexPointer(3, GL10.GL_FLOAT, 0, vertexBuffer);
    gl.glTexCoordPointer(2, GL10.GL_FLOAT, 0, textureBuffer);

    //Disable the client state before leaving
    gl.glDisableClientState(GL10.GL_TEXTURE_COORD_ARRAY);

    for(int i=0; i<parts.size(); i++){
        TDModelPart t=parts.get(i);
        gl.glNormalPointer(GL10.GL_FLOAT, 0, t.getNormalBuffer());
        gl.glDrawElements(GL10.GL_TRIANGLES,t.getFacesCount(),GL10.GL_UNSIGNED_SHORT,t.getFaceBuffer());
        gl.glDisableClientState(GL10.GL_VERTEX_ARRAY);
    }
}

public void buildVertexBuffer(){
    ByteBuffer vBuf = ByteBuffer.allocateDirect(v.size() * 4);
    vBuf.order(ByteOrder.nativeOrder());
    vertexBuffer = vBuf.asFloatBuffer();
    vertexBuffer.put(toPrimitiveArrayF(v));
    vertexBuffer.position(0);

    vBuf = ByteBuffer.allocateDirect(texture.length * 4);
    vBuf.order(ByteOrder.nativeOrder());
    textureBuffer = vBuf.asFloatBuffer();
    textureBuffer.put(texture);
    textureBuffer.position(0);
}

private static float[] toPrimitiveArrayF(Vector<Float> vector){
    float[] f;
    f=new float[vector.size()];
    for (int i=0; i<vector.size(); i++){
        f[i]=vector.get(i);
    }
    return f;
}

/**

public void loadGLTexture(GL10 gl, Context context) {
    // loading texture
    Bitmap bitmap = BitmapFactory.decodeResource(context.getResources(),
            R.drawable.nehe);

    // generate one texture pointer
    gl.glGenTextures(1, textures, 0);
    // ...and bind it to our array
    gl.glBindTexture(GL10.GL_TEXTURE_2D, textures[0]);

    // create nearest filtered texture
    gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MIN_FILTER, GL10.GL_NEAREST);
    gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MAG_FILTER, GL10.GL_LINEAR);

    //Different possible texture parameters, e.g. GL10.GL_CLAMP_TO_EDGE
    //gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_S, GL10.GL_REPEAT);
    //gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_T, GL10.GL_REPEAT);

    // Use Android GLUtils to specify a two-dimensional texture image from our bitmap 
    GLUtils.texImage2D(GL10.GL_TEXTURE_2D, 0, bitmap, 0);

    // Clean up
    bitmap.recycle();
}

public void onSurfaceCreated(GL10 gl, EGLConfig config) {
    gl.glLightfv(GL10.GL_LIGHT0, GL10.GL_AMBIENT, lightAmbientBuffer);      
    gl.glLightfv(GL10.GL_LIGHT0, GL10.GL_DIFFUSE, lightDiffuseBuffer);      
    gl.glLightfv(GL10.GL_LIGHT0, GL10.GL_POSITION, lightPositionBuffer);    
    gl.glEnable(GL10.GL_LIGHT0);

    model.loadGLTexture(gl, context);
    gl.glEnable(GL10.GL_TEXTURE_2D);
    gl.glShadeModel(GL10.GL_SMOOTH);

公共作废提取（GL10 gl）{

（目前，我将忽略您在未启用
GL\u NORMAL\u数组时设置
glnormal指针的情况

请始终记住，OpenGL是一个状态机，所有操作，尤其是draw调用，在调用时都在当前状态上运行，并且该状态不会改变，除非您自己改变它（这里的“您”指的是应用程序代码，包括使用相同OpenGL上下文的任何其他第三方组件）

gl.glDisableClientState(GL10.GL_TEXTURE_COORD_ARRAY);
