Question

我的渲染器有以下代码：

package hello.project;

import javax.microedition.khronos.opengles.GL10;

import android.content.Context;
import android.opengl.GLSurfaceView.Renderer;

public class HelloOpenGLES10Renderer implements Renderer {

    private Square      square;

    private Square3     square3;
    private SquareAccesories        squareAcc;
    private SquareEyes      squareEyes;
    private SquareLips      squareLips;
    private SquarePants     squarePants;
    private SquareShoes     squareShoes;
    private Context     context;
    //public static int w,h;


    /** Constructor to set the handed over context */
    public HelloOpenGLES10Renderer(Context context) {
        this.square     = new Square();
        this.square2        = new Square2();

        this.squareShoes        = new SquareShoes();
        this.context=context;
    }

    public void onDrawFrame(GL10 gl) {

        if (Project.ifDraw){
            Square.loadGLTexture(gl, this.context,Square.getSex()); 
            Square2.loadGLTexture(gl, this.context,Square2.getHair());
            Square3.loadGLTexture(gl, this.context,Square3.getDress());

        gl.glClear(GL10.GL_COLOR_BUFFER_BIT | GL10.GL_DEPTH_BUFFER_BIT);
        gl.glMatrixMode(GL10.GL_MODELVIEW);
        gl.glLoadIdentity(); 
        //GLU.gluPerspective(gl, 45.0f, (float)w / (float)h, 0.1f, 100.0f);
        GLU.gluLookAt(gl, 0, 1, 5, 0f, 0f, 0f, 0f, 1.0f, 0.0f);
        gl.glColor4f(1.0f, 1.0f, 1.0f, 2.0f);
        square.draw(gl);

        // Reset the Modelview Matrix

        gl.glTranslatef(0.0f, 0.0f, -5.0f);  // move 5 units INTO the screen
        square.draw(gl);
        square2.draw(gl);*/ 
    }

    public void onSurfaceChanged(GL10 gl, int width, int height) {
        if(height == 0) {                       //Prevent A Divide By Zero By

        //w=width;

        //Square2.loadGLTexture(gl, this.context,Square2.getHair()); 
        gl.glViewport(0, 0, width, height);     //Reset The Current Viewport

        gl.glLoadIdentity();                    //Reset The Mode   lview Matrix
    }

    public void onSurfaceCreated(GL10 gl, EGLConfig config) {
        // Load the texture for the square
        gl.glEnable(GL10.GL_BLEND);
        gl.glEnable(GL10.GL_TEXTURE_2D);

        gl.glClearColor(0.0f, 0.0f, 0.0f, 0.0f);  //Black Background
        gl.glClearDepthf(1.0f);      //Depth Buffer Setup
        gl.glDepthFunc(GL10.GL_NEVER);    //The Type Of Depth Testing To Do

        //Really Nice Perspective Calculations
        gl.glHint(GL10.GL_PERSPECTIVE_CORRECTION_HINT, GL10.GL_NICEST); 
    }
}

在模拟器上，它完美无缺。我使用了Xperia Play进行调试，并在HTC xplorer和Galaxy Nexus上进行了尝试，并且它运行良好。 2天我在三星Galaxy和HTC手机上试过但是SurfaceView没有显示任何内容，它是空白的，任何想法为什么会发生这种情况？

制作图片尺寸2的功率并知道它有效

为什么OpenGL在某些手机上运行而在其他手机上运行？
