尝试着把min3d引擎移植到android stdio上开发，开始的时候遇到不少问题，所以在CSDN上开个帖。同时感谢美丽同事XY的帮忙。

第一个问题：一开始把min3d包导入Android stdio后，在MainActivity中提示“improt unused imports statement”，然后声明了对象，也同样没用。

后来上谷歌查了不少资料，在另一篇CSDN博客上找到了一项设置：

然后点 ok，这样 Android stdio就懂得自动导入响应的包。import就不会报错了。

第二个问题：在Android stdio上新建的空工程，public class MainActivity extends AppCompatActivity。而min3d要显示跑起来，需要继承的是RendererActivity。所以修改的代码如下：

package com.example.zk.min3d_demo;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.DisplayMetrics;
import android.view.Window;
import android.view.WindowManager;
import android.widget.FrameLayout;

import min3d.animation.AnimationObject3d;
import min3d.core.Object3dContainer;
import min3d.core.RendererActivity;
import min3d.objectPrimitives.Box;
import min3d.parser.IParser;
import min3d.parser.Parser;
import min3d.vos.Light;

public class MainActivity extends RendererActivity {
//public class MainActivity extends AppCompatActivity {
    Object3dContainer faceObject3D;     //3D对象
    private AnimationObject3d ogre;
    private RockerView rockerView1;
    float modelx = 0;
    float modely = 0;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);
        //frame3dView
        FrameLayout ll = (FrameLayout) this.findViewById(R.id.frame3dView);
        //在xml中，指定显示的控件，这里是一个FrameLayout。
        ll.addView(_glSurfaceView);//加入到_glSurfaceView中显示。

        rockerView1 = (RockerView) findViewById(R.id.rockerView1);
        rockerView1.setRockerChangeListener(new RockerView.RockerChangeListener() {

            @Override
            public void report(float x, float y) {
                // TODO Auto-generated method stub
                modelx = x/1000;
                modely = y/1000;
            }
        });

    }

    public void initScene() {
        scene.lights().add(new Light());

        IParser parser = Parser.createParser(Parser.Type.MD2,
                getResources(), "com.example.zk.min3d_demo:raw/ogro", false);
        parser.parse();

        ogre = parser.getParsedAnimationObject();
        ogre.scale().x = ogre.scale().y = ogre.scale().z = .07f;
        ogre.rotation().z = -90;
        ogre.rotation().x = -90;
        scene.addChild(ogre);
        ogre.setFps(70);
        ogre.play();
    }

    public void updateScene() {
        //     faceObject3D.rotation().x++;//围绕着X轴旋转，正数为顺时针，速度由X的数值变化决定
        ogre.rotation().x +=modelx;//设置初始位置，平截头体中xyz的坐标位置
        ogre.position().y +=modely;
    }
}
