我在这里要做的是在我单击主要活动中的列表视图项目时加载 OpenGL 上下文。
看起来很简单!但我真的不知道如何将主要活动与 OpenGL 活动联系起来。任何人都可以给我一些提示吗?
谢谢!!
编辑:在这里添加一些代码:
在主要活动中:
listView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Intent launchGL = new Intent(getApplicationContext(), OpenGLActivity.class);
startActivity(launchGL);
}
});
在 OpenGL 活动中:
public class OpenGLActivity extends Activity {
private GLSurfaceView mGLSurfaceView;
@Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
mGLSurfaceView = new GLSurfaceView(this);
// Check if the system supports OpenGL ES 2.0.
final ActivityManager activityManager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
final ConfigurationInfo configurationInfo = activityManager.getDeviceConfigurationInfo();
final boolean supportsEs2 = configurationInfo.reqGlEsVersion >= 0x20000;
if (supportsEs2)
{
// Request an OpenGL ES 2.0 compatible context.
mGLSurfaceView.setEGLContextClientVersion(2);
// Set the renderer to our demo renderer, defined below.
mGLSurfaceView.setRenderer(new MyRenderer());
}
else
{
// This is where you could create an OpenGL ES 1.x compatible
// renderer if you wanted to support both ES 1 and ES 2.
return;
}
setContentView(mGLSurfaceView);
}
}
(使用一些教程代码进行实验)
