详解Android获得系统GPU参数 gl.glGetString

详解android获得系统gpu参数 gl.glgetstring

通过文档的查找，以及源码的剖析，android的gpu信息需要通过opengl来获取，android framework层提供gl10来获取相应的参数，而gl10要在使用自定义的view时才可以获得，下面是获得gpu信息的例子：

1.实现render类

class demorenderer implements glsurfaceview.renderer { 
 
  public void onsurfacecreated(gl10 gl, eglconfig config) 
  { 
    log.d("systeminfo", "gl_renderer = " +gl.glgetstring(gl10.gl_renderer));  
    log.d("systeminfo", "gl_vendor = " + gl.glgetstring(gl10.gl_vendor));  
    log.d("systeminfo", "gl_version = " + gl.glgetstring(gl10.gl_version));  
    log.i("systeminfo", "gl_extensions = " + gl.glgetstring(gl10.gl_extensions));  
  } 
 
 
  @override 
  public void ondrawframe(gl10 arg0) { 
    // todo auto-generated method stub 
 
  } 
 
 
  @override 
  public void onsurfacechanged(gl10 arg0, int arg1, int arg2) { 
    // todo auto-generated method stub 
 
  } 
 
} 

2.实现glsurfaceview

class demoglsurfaceview extends glsurfaceview { 
 
  demorenderer mrenderer; 
  public demoglsurfaceview(context context) { 
    super(context); 
    seteglconfigchooser(8, 8, 8, 8, 0, 0); 
    mrenderer = new demorenderer(); 
    setrenderer(mrenderer); 
  } 
} 

3.在activity中 new 一个 demoglsurfaceview 对象

4.设置这个view对象

public class demo extends activity { 
  @override 
  public void oncreate(bundle savedinstancestate) { 
    super.oncreate(savedinstancestate); 
    glsurfaceview glview = new demoglsurfaceview(this); 
    this.setcontentview(glview); 
  } 
} 

以上就是android获取gpu 参数的例子，如果大家研究android gpu 的知识，必须研究android gpu的源码，这里只是给个小例子，希望能帮助到大家，谢谢大家对本站的支持！
