OpenGLES无法设置渲染

作为初学者,我正在关注“构建OpenGLES环境”文档。我只是想画一个灰色的屏幕。我按照建议编写了每一步,但Eclipse仍然在MyGLSurfaceView类和MyRenderer类中给出了错误。他们在这里

主要活动

package com.example.testopengl;

import android.opengl.GLSurfaceView;
import android.os.Bundle;
import android.app.Activity;

public class OpenGLES20Activity extends Activity {

    private GLSurfaceView mGLView;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);


        mGLView = new MyGLSurfaceView(this);
        setContentView (mGLView);

}


}

MyGLSurfaceView类

package com.example.testopengl;

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

public class MyGLSurfaceView extends GLSurfaceView {


    public MyGLSurfaceView (Context context) {
        super (context);

        setEGLContextClientVersion(2);

        setRenderer(new MyRenderer());

        setRenderMode (GLSurfaceView.RENDERMODE_WHEN_DIRTY);
    }

}

MyGLRenderer类

package com.example.testopengl;

import javax.microedition.khronos.opengles.GL10;

import android.opengl.EGLConfig;
import android.opengl.GLES20;

public class MyGLRenderer implements GLSurfaceView.Renderer {

    public void onSurfaceCreated (GL10 unused, EGLConfig config) {
        GLES20.glClearColor(0.0f, 0.0f, 0.0f, 1.0f);
    }

    public void onDrawFrame (GL10 unused) {
    GLES20.glClear (GLES20.GL_COLOR_BUFFER_BIT);    
    }

    public void onSurfaceChanged (GL10 unused, int width, int height) {
        GLES20.glViewport(0, 0, width, height);

    }

}

在此行setRenderer(new My Renderer())MyGLSurfaceView类中弹出错误;

在公共类的MyGLRenderer类中MyGLRenderer实现GLSurfaceView.Renderer

1 个答案:

答案 0 :(得分:0)

您在渲染器中使用的方法是静态方法:您需要执行以下操作才能使代码正常工作:

import static android.opengl.GLES20.*

然后您可以无限制地使用这些静态函数:

public void onSurfaceChanged (GL10 unused, int width, int height) {
    glViewport(0, 0, width, height); // this is a static method
}
