Comprehensive example of Android 3D Game implementation (preliminary)

The effect is a little more harmonious than the code in March, but it still needs to be improved. Now I will send the code.

(1) Activity Class

Package SIM. feel; import Java. io. ioexception; import Java. io. inputstream; import android. app. activity; import android. content. res. assetmanager; import android. content. res. resources; import android. graphics. bitmap; import android. graphics. bitmapfactory; import android. openGL. glsurfaceview; import android. OS. bundle; import android. view. window; import android. view. windowmanager; public class advancedexample extends activity {// glsurfaceview private glsurfaceview glview; // instantiate myrenderer object private myrenderer mr = new myrenderer (); @ override public void oncreate (bundle savedinstancestate) {super. oncreate (savedinstancestate); // you can specify the value of requestwindowfeature (window. feature_no_title); // sets full screen getwindow (). setflags (windowmanager. layoutparams. flag_fullscreen, windowmanager. layoutparams. flag_fullscreen); // init LoadFile new LoadFile (getresources (); glview = new glsurfaceview (this); glview. setrenderer (MR); setcontentview (glview) ;}// load the file class LoadFile {public static resources resource; Public LoadFile (Resources res) {resource = res ;} // file public static inputstream loadf (string filename) {assetmanager AM = LoadFile. resource. getassets (); try {return AM. open (filename) ;}catch (ioexception e) {return NULL ;}// image public static bitmap loadi (int id) {Bitmap bitmap = bitmapfactory. decoderesource (resource, ID); Return bitmap ;}}
