【Android】ViewPager+GridView结合使用报错？

首先声明下程序是可运行的代码，运用一个initViewPager();方法初始化ViewPager和GridView。我想把初始化GridView初始化放在initGridView中该如何写这部分代码。因为XML文件无错所以就不上了，JAVA代码如下。

 public class MainActivity extends Activity {    private View tab01 = null;    private View tab02 = null;    private ViewPager mViewPager = null;    private List<View> tabList = null;    private PagerAdapter mAdapter = null;    private GridView mGridView = null;    private List<Map<StringObject>> mData = new ArrayList<Map<StringObject>>();    private SimpleAdapter gAdapter = null;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        initViewPager();//      initGridView();         }    private void initGridView() {    }    private List<Map<String Object>>  getData() {        int[] image = {R.drawable.icon_clouddayR.drawable.icon_fog                R.drawable.icon_rainR.drawable.icon_snowR.drawable.icon_sunnyday};        String[] name = {""图一""图二""图三""图四""图五""};        for(int i=0;i<name.length;i++){            Map<StringObject> map = new HashMap<StringObject>();            map.put(""image"" image[i]);            map.put(""name"" name[i]);            mData.add(map);        }        return mData;    }    private void initViewPager() {        this.mViewPager = (ViewPager) findViewById(R.id.mViewPager);        LayoutInflater mInlfater = getLayoutInflater();        this.tab01 = mInlfater.inflate(R.layout.tab01 null);        this.tab02 = mInlfater.inflate(R.layout.tab02 null);        this.tabList = new ArrayList<View>();        tabList.add(tab01);        tabList.add(tab02);        mAdapter = new PagerAdapter() {            @Override            public boolean isViewFromObject(View arg0 Object arg1) {                // TODO Auto-generated method stub                return arg0 == arg1;            }            @Override            public int getCount() {                // TODO Auto-generated method stub                return tabList.size();            }            @Override            public void destroyItem(ViewGroup container int position                    Object object) {                // TODO Auto-generated method stub                container.removeView(tabList.get(position));            }            @Override            public Object instantiateItem(ViewGroup container int position) {                // TODO Auto-generated method stub                container.addView(tabList.get(position));                return tabList.get(position);            }        };        mViewPager.setAdapter(mAdapter);            //--------↓        this.mGridView = (GridView)tab02.findViewById(R.id.mGridView);        this.gAdapter = new SimpleAdapter(this getData()R.layout.griditem                new String[] {""image""name""}new int[] {R.id.imageR.id.name});        this.mGridView.setAdapter(gAdapter);        //--------↑        //以上代码是否可以放在initGridView()中实现，有待考证。    }}

如代码所示

解决方案

Android - Fragment+ViewPager结合使用
android控件篇：ViewPager+Fragment+GridView的使用（与AndroidQuery框架结合）
Android结合fragment灵活使用ViewPager

解决方案二：
可以，保证方法调用先后顺序，放进去调试一下即可。
